Meaning of Life and Socrates Essay

Socrates was considered by many to be the wisest man in ancient Greece. While he was eventually condemned for his wisdom, his spoken words are still listened to and followed today. When, during his trial, Socrates stated that, â€Å"the unexamined life is not worth living† (Plato 45), people began to question his theory. They began to wonder what Socrates meant with his statement, why he would feel that a life would not be worth living. To them, life was above all else, and choosing to give up life would be out of the picture. They did not understand how one would choose not to live life just because he would be unable to examine it. Socrates felt that if he was unable to examine life, he would not be really living. To Socrates, living meant being able to question the world around him. Examining life gives one freedom. Once one examines himself and understands who he is, he can take control of his life. Socrates believed that the ability to ask, to examine, and to understand would make a life whole. He believed that the purpose of life was to grow, both physically and spiritually. Being able to explore and understand would lead to a deeper understanding of the world around us as well as a deeper understanding of ourselves. (Plato 46) Socrates felt that, above all, one should be a good citizen and always do the right thing (Plato 18). However, many in his time did not worry about doing what was correct. Socrates realized this, and understood that they did not care to look into their actions and beliefs. Their first thoughts were on the goals that they had, such as money and pleasure, rather than the thought of whether or not the goals they held were actually what should have been considered important and right (Plato 26). Socrates knew that, unless they took the time to question their lifestyles, they would never do the right thing. By living a life that was being examined, the citizens would be living a life that was, for the most part, also right. Socrates†¦ Personally, I have found great value in examining the wisdom of many acts in my life, yet there are many types of people in this world, and if some do not ponder the wisdom of their actions much at all, must we (or particularly they) conclude their life is less worth living? It seems awfully condescending. The people who don’t examine their lives much probably aren’t examining Socrates statement. If they did, they might object to the interpretation with which it is adopted by philosophers. The live in which I let other people tell me what the questions of life are, the life in which I let other people give me their answers without my thinking through to my own answers, is the unexamined life. Socrates is saying that the life in which I ask my own questions and answer them for myself in a reasonable manner is a more valuable life than the unexamined life. The examined life is so much better than an unexamined life that Socrates is willing to die for that value. Through out generations, mankind has been asking themselves what is the purpose of life. And obviously, it would not easy for one alone to answer or explain what the meaning of life is. Nevertheless, one’s life is monotonous if it is meaningless, and it is not monotonous if it has a purpose, a target to go. Thus, the question here is how one knows that his life is worth living or not? Socrates, the father of ancient philosophy, once stated, â€Å"An unexamined life is not worth living. † In order to make one life becomes worth to live, this famous statement strongly addresses that one must exanimate himself first and then others in the society to find the meaning and happiness of life. After reading Plato’s account of Socrates defense, the Apology, I was completely blown away by the power of Socrates words and ideas. The reading left me thinking about how I felt regarding what he had said about virtue, truth and the quest for both. In class, we discussed Socrates search for virtue and we touched on the topic of this paper: the reasons Socrates believed that â€Å"the unexamined life is not worth living for man†. It is my opinion that he is correct in that view and in this paper I intend to show you why. Like many philosophers alive in his time, it was Socrates belief that virtue could only be attained through examination. Only through exploration can you really understand what virtue is, and begin to act virtuously. Understanding, as well as sharing, this information was very important goal to Socrates. The significance of examining and understanding our lives is far greater than one might think. Understanding and comprehending the behavior of friends, as well as of ourselves, enables us to have empathy and compassion for them. And, allows us not to stand in judgment, which, in turn, allows us to live the moral, noble lives that Socrates spoke of. As one analyzes the â€Å"Apology† by Plato, one is able to analyze and contrast and most people would agree with Socrates when he claims that â€Å"†¦the unexamined life is not worth living†¦Ã¢â‚¬ . From a more personal standpoint I would completely agree with Socrates point of view, due to the fact most of us in society have chosen to live the â€Å"unexamined life† for centuries and as a result we live in a society where one has to live segregated from our freewill as human beings as well as a society that is restrained by rules and other types of social â€Å"walls†. When one reads and is able to contrast Plato’s â€Å"Allegory of the Cave† it clearly shows a great and perhaps the most clear example of the point that Socrates was attempting to make to the jury, in the â€Å"Apology†. For example in Plato’s â€Å"Allegory of the Cave†, Plato makes the reader visualize a cave where there are a great number of prisoners who are restrained and are faced staring at the wall where all they can see is shadow movements that are projected from a fire that is placed right behind these prisoners, and this fire is displaying false images from what appears to be images of the outside world. As the story proceeds, one of the prisoners manages to pe the cave and he walks outside into the â€Å"real† world and is able to see a completely different view of the real world and this prisoner is able to see a completely different image of the outside world, different from the images that the shadows inside the cave were exposing to the prisoners. What Socrates is implying is that if one decides not to discover thyself and attempts to focus more on material interest and the acquisition of personal power, one is capable of abusing this power to an extent where it may result in havoc and possibly the destruction of those who occupy the state, either emotionally or physically and all as a result of decisions that were not taken into consideration before being applied. † What I was able to grasp from this quote that Socrates phrased is that one has the wisdom to accomplish anything in one’s personal life, but one should able to find our soul and locate the wisdom that one contains inside the mind before one attempts to reach personal obstacles in life. the greatest good of all man is daily to converse about virtue. When the time for the exam came along I decided not cheat in the exam simply because I was going to have to live with a guilty conscious for quite sometime and although cheating on the exam appeared tempting at the time I still needed some time to myself and ponder about the decision that I had to make that was probably going to damage my personal morality as an individual. † The part of the phrase that really caught my attention is when Socrates says â€Å". † What Socrates is trying to make us see is that the more one speaks about virtue the more a person is able to learn about the â€Å"virtues† of one’s personal life, or in other words we are able to acquire more knowledge of the human mind and its capabilities. I did not go where I could do no good to you or to myself; but where I could do the greatest good privately to everyone of you , thither I went, and sought to persuade every man among you that he must look to himself , and seek virtue and wisdom before he looks to his private interests, and look to the state before he looks to the interests of the state; and that this should be the order which he observes in all his actions. In my third semester in Santa Monica College I was taking a math class and during the first month of the semester I had already taken two exams and had failed on both, as a result before the day of the third exam arrived I was feeling somewhat nervous due to the fact that I was not prepared to take this exam. So as the moment was arriving for this exam, I began to ponder about idea of cheating in order for the results to go my way. When the escaped prisoner decides to go into the cave and attempts to explain to the other prisoners about what is really occurring in the outside world, the other prisoners decide to gain up on the â€Å"liberated† prisoner, because they were not prepared to see reality for what it really is, so they decided to chose to somewhat live the life of a â€Å"social slave† and not the life of a person who lives a life of freedom nor freewill. Another quote that Socrates applies in this story is when he quotes â€Å". The same thing goes for the â€Å"unexamined life†, sometimes we as a human being attempt to achieve a certain level of success in life and sometimes at the expense of others and although we may acquire success, we will always live with the conscious of such guilt that later on in life it is going to comeback and hunt us. â€Å"The unexamined life is not worth living. † (Apology, p. 41) Socrates held him self up to this standard by allowing the courts to take his life because they would not allow him to continue his quest set forth by the Oracle. An unexamined life would be just coasting through and not making any decisions or asking any questions. Socrates could not see a point in living if you were unable to ask questions and challenge your way of thinking. An examined life would be trying to understand your purpose and the current state of things. By examining your life, therefor understanding yourself, you will not be subject to actions motivated by passion or instinct. Socrates demonstrated this when Crito arrived at his jail cell with news that he could help Socrates escape. This was an event where they had to act quickly, however Socrates said â€Å"Let us examine the question together, my dear friend, and if you can make any objection while I am speaking, make it and I will listen to you, but if you have no objection to make, my dear Crito, then stop now from saying the same thing so often, that I must leave here against the will of the Athenians. I think it important to persuade you before I act, and not to act against your wishes. See whether the start of our enquiry is adequately stated, and try to answer what I ask you in the way you think best. † (Crito, p. 51) Socrates examines the situation with Crito instead of acting hastily. This example displays how dedicated Socrates was to his way of thinking, and helps explain Socrates actions in court. Meletus was the catalyst of this case brought against Socrates. Meletus’s affidavit said â€Å"Socrates is guilty of wrongdoing in that he busies himself studying things in the sky and below the earth; he makes the worse into the stronger argument, and he teaches these same things to others. † (Apology, p. 25) Socrates says all these claims are false and challenges anyone in the court to speak up if they are true. Socrates was also accused of corrupting the young and of not believing in the gods the city believed in but believing in his own gods. Socrates attacked each of these accusations point by point. To disprove the accusation that he corrupts the young he says â€Å"They say: That man Socrates is a pestilential fellow who corrupts the young. If one ask them what he does and what he teaches to corrupt them, they are silent, as they do not know. † (Apology, p. 29) To disprove the statement that he does not believe in the gods the city believes in, he starts to question the jury. Socrates states â€Å"Does any man, Meletus, believe in human activities who does not believe in humans? † â€Å"Or in flue-playing activities but not in flute-players? † (Apology, p. 32) Socrates sets up these analogies so he can compare them to the statements that he does not believe in any gods. Socrates then applies this analogy to himself by saying. â€Å"Then since I do believe in spirits, as you admit, if spirits are gods, this is what I mean when I say you speak in riddles and in jest, as you state that I do not believe in gods and then again that I do, since I do believe in spirits†. (Apology, p. 32) Socrates in his defense is trying to prove that Meletus’s charges are blown out of proportion and they are wasting the courts time. Socrates is posed with the question â€Å"Are you not ashamed, Socrates, to have followed the kind of occupation that has led to your being now in danger of death? † (Apology, p. 33) Socrates replies â€Å"Whenever a man has taken a position that he believes to be best, or has been placed by his commander, there he must I think remain and face danger, without a thought for death or anything else, rather than disgrace. † (Apology, p. 33) Socrates is saying when you dedicate your life or you strongly believe in a belief or subject no matter what the danger, you should still stand behind your beliefs. By doing this, you live an examined life. In Socrates case, if he were to accept the punishment of never practicing philosophy he would be living an unexamined life because he could just set aside his beliefs and move on through life. Socrates explains his passion for philosophy by saying â€Å"Gentlemen of the jury, I am grateful and I am your friend, but I will obey the god rather than you, and as long as I draw breath and am able, I shall not cease to practise philosophy, to exhort you and in my usual way to point out to any one of you whom I happen to meet. † (Apology, p. 34) The way Socrates explains himself to the jury, I see a man who truly believes in what he preaches. He demonstrates that he has lived an examined life, and even with the threat of death and an opportunity to escape death, he sticks with what he truly believes is right. He questions everything and will not accept ignorance. However I feel that since Socrates was at the age of 70 his fear of death was dramatically reduced. I think if he were younger he would have taken the opportunity Crito presented to escape, so he could continue his quest. â€Å"Now the hour to part has come. I go to die, you go to live. Which of us goes to the better lot is know to no one, except the god. † (Apology, p. 44).

Indiana Jones: Raiders of the Lost Ark Hero’s Journey Analysis Essay

Ordinary World In the first opening scene we see is Indiana Jone’s whip in his pocket. Then we see the hat from behind and that is when the die-hard Indiana Jones fans realize that they are witnessing the entrance of a great hero. The ordinary world for Indiana Jones is really not that boring at all. He is constantly hit on by many undergraduates that he teaches in his Archaeology class. A prime example being an extremely attractive undergraduate girl closes her eye lids to display the message â€Å"LOVE YOU.† The Call The call to action in this movie was when the two federal agents came to enlist the help of Indiana Jones to acquire the Ark of the Covenant. Indiana Jones informs them of the history behind the Ark and is informed that the Nazis have found Tanis the last known location of the Ark. Jones informs the federal agents that he is no expert on the subject of Ark myth, but they should be asking Abner Ravenwood. Ravenwood collected many relics of Tanis including the head piece to the Staff of Ra. The head piece is the key to finding the Well of Souls where the Ark is kept. The Refusal Indiana Jones is gung ho about embarking on his quest to find the Ark of the Covenant. Marcus Brody, the head curator of the National Museum tells Jones that is might not be a good idea to go seeking the Ark. Brody expresses his convern when he says, â€Å"Well, I mean that for nearly three thousand years man has been searching for the lost ark. It’s not something to be taken lightly. No one knows its secrets. It’s like nothing you’ve ever gone after before.† Jones tells Brody not to worry, for he does not believe in the supernatural.† Meeting the Mentor This movie has a slight twist in terms of meeting the mentor. The mentor, Abner Ravenwood is mentioned but we never get to meet him, for Jones and he had a falling out many years prior. Jones later meets up with Sollah who guides him through Egypt. Crossing the Threshold In this movie, however, Jones goes to Nepal to go see Marion, Abner Ravenwoods’ daughter, to obtain the head piece to the Staff of Ra. Accomplishing this task is not easy for Jones because a romantic encounter he had with Marion years earlier. Test Allies & Enemies Indiana Jones is greeted quite rudely when he enters through Marion’s door she says, â€Å"Always knew someday you’d come back through my door!† and then proceeds to punch him, â€Å"In the last ten years, I learned to hate you. I was a child. You knew what you were doing.† Jones finds out that his mentor is dead. He gives her money to buy the head piece, and she tells him to come back tomorrow to retrieve it. After Jones leaves the bar, agents from the German Gustapo looking for the head piece. They subdue her and threaten to burn her with a hot poker in order to torture her for information about the whereabouts the head piece. Right as they are about to start the torment Jones comes in and saves her by whipping out the hot poker out of the tormentor’s hands. The hot poker lights the curtains ablaze resulting in the head piece heating up. The head Gustapo officer grabs the medallion and burns his hands in the process. Marion then pays back the favor to Jones by shooting an assailant saving Jones’ life. She looks and turns to Jones and says, â€Å"I’m your god damned partner!† At this point a partnership has been formed and we have Jones’ first major ally in the quest to find the Ark. The Approach * They arrive in Cairo in Egypt, where they meet up with Sollah, and an old colleague of Jone’s. * Rene Belloch is running the archaeological dig in Tannis * The Germans have found the map room that Jones had mentioned before, but cannot find the location to the Well of Souls without the head piece. * Sollah acts as their guide and warns them of the dangers * â€Å"The Ark. If it is there, at Tanis, then it is something that man was not meant to disturb. * Death has always surrounded it. It is not of this earth.† – Sollah * Jones and Marian start to rekindle their relationship * They are attacked by the Nazis and Jones throws Marion in a basket to keep her safe from harm * While hiding in the basket the monkey hops on the top cover of the basket, giving her position away * Indiana Jones seeks out Marion but is unable to find her * He shoots the explosives truck and the truck explodes which leads Jones to believe that Marian is dead * He meets up with Sollah after and they come to the conclusion that they only have one side of the head piece * The Nazis are digging in the wrong place * Sollah and Jones realize they do not have much time, for they must get to the map room around 9:00am when the sun hits the map room * The sun shines through and points them to the location where they must dig * Jones goes to Balloch’s tent and finds Marion * Jones promises to come back for her after he retrieves the Ark * They find the entrance to the Well of Souls when they are ambushed by Belloch and his Nazi cohorts Supreme Ordeal Jones is locked inside with Marion in the Well of Souls. The floor is covered with snakes which makes this even more excruciating for Jones. Snakes are Jones’ worst fear and he despises them with a passion. At this point it seems as if all hope is lost, but Jones and Marion manage to escape the Well of Souls and try to flee the archeological dig site at Tannis. The Reward After a fistfight with a giant Nazi mechanic, blowing up an airplane on the airstrip, and chasing down a fleet of trucks, Jones takes back the Ark before it can be shipped to Berlin. He obtains what he was looking for all along plus he has Marion by his side, which is what he really wanted all along. The Road Back Indiana and Marion leave Cairo to escort the Ark to England on board a steam boat. The next day, their boat is breached by Belloch, and the Nazis, who once again steal the Ark and kidnap Marion. Indiana stows away on their U-boat and follows them to an isolated island where Belloch plans to test the power of the Ark before presenting it to Hitler. Indiana reveals himself and threatens to destroy the Ark with a rocket-propelled grenade launcher, but Belloch calls his bluff, knowing Jones cannot bear to eradicate an important historical artifact. The Resurrection Indiana surrenders and is tied to a post with Marion as Belloch performs a ceremonial opening of the Ark, which appears to contain nothing but sand. Belloch’s Nazi cohorts start laughing thinking they had just wasted their time. Suddenly, angels start to emerge from the Ark. Aware of the supernatural danger of looking at the opened Ark, Indiana warns Marion to close her eyes. The apparitions suddenly morph into gruesome creatures of death, and lightning bolts and burst of fire and flame begin flying out of the Ark, killing the Nazi soldiers, while Belloch and the rest of the commanding officers meet their fates as well. Return with Elixir Indiana and Brody ask about the whereabouts of the ark and are informed by the federal agents that the Ark â€Å"is someplace safe† to be studied by â€Å"top men†. The Ark is sealed in a wooden crate and stored in a giant government warehouse in Area 51 filled with countless similar crates.

Jing-Mei Character Analysis

Amy Tan’s short story â€Å"Two Kinds† illustrates a young girls struggle with her highly opinionated mother and finding her own way. Jing-Mei’s mother continually enforces Jing-Met to carry out tasks the way she wants her to, her way. Therefore Jing-Mei is unable to grow as her own person and carry out the choices she wants to. Throughout Jing-Mei’s journey she begins to develop negative thoughts of herself and displays the attributes of insecurity, stubbornness and cruelty.Jing-Mei’s stubbornness encourages her to believe her mother is being unfair and cruel, â€Å"when [her] mother had told [her] this, [she] felt as though [she’s] been sent to hell. † When in reality, all her mother is doing is guiding her so she won’t have to go through the hardships she herself had gone through (Page 5). Jing-Mei has no desire to cooperate with her mother. She fights with her every way she can, determined to extinguish her mother’s d reams of her becoming successful, Jing-Mei neglects her studies as well as the piano.Jing-Mei believes her mother is trying to change her, Jing-Mei states â€Å"I won’t let her change me†¦ I won’t be what I’m not†¦Ã¢â‚¬  despite her mother’s real intentions of her becoming successful (Page 3). Jing-Mei feels she must reject her mother in order to find herself â€Å"right then and there, [she] was determined to put a stop to her foolish pride. † however, in doing so, she is rejecting her heritage and identity (Page 7).Suyuan Woo’s constant criticism hands Jing-Mei the idea of lack of affection, which results in Jing-Mei’s insecurity. Suyuan’s values of family obedience, concealment of unnecessary emotions, and criticism as expressions of love contrast with Jing-Mei’s American ideas of independence, self-esteem and open expressions of love guide Jing-Mei’s belief of never fulfilling her mother’s e xpectations. Therefore, Jing-Mei constantly puts herself down â€Å"[she] looked in the mirror†¦ [she] began to cry, such a sad ugly girl! due to misunderstanding her mother’s intentions (Page 3). Her mother’s high expectations and criticism are her way of expressing love and faith in her daughter. Jing-Mei misunderstands her mother’s actions which lead her to the conclusion that she will â€Å"never be the kind of daughter [her mother] wants her to be† and leads her to the question of â€Å"why don’t you like me the way I am? I am not a genius! † (Page 10,5).

Government Higher Education Policies Essay Example | Topics and Well Written Essays - 1750 words

Government Higher Education Policies - Essay Example It may entail acquisition of new skills and information or merely boost an understanding of already existing elements. Through education, a generation that breeds an alteration of society virtues is created and these develop the environment positively as they strive to achieve constant progress. These institutions further provide a platform involving social interaction measures as different cultural affiliations and individual behaviors cross (Hasley et. al., 1997, 14). The system limits discrimination as it involves assembling different ethnic affiliations with constantly environmental entities and technology. An educational government entity entails numerous models that constitute its functionality. It promotes individual intellectual development as they mature into adulthood faced with tough societal advancements. The system also works towards producing skilled individuals that are capable of propagating advancement in the technology to boost an impending economy. However, the edu cational policy entails a careful use of resources that need adequate provision especially by the government to instigate its advancement. There need to be sufficient resources availability to accommodate the entire population using the facility. It is the government duty to check on syllabus revision and provision of qualified professionals to help advance the learning process. A deficiency in any entity that supports the education policy negatively influences general institutional and individual improvement. There have been numerous policy changes in the UK educational system to advance the performance in the Higher Education institution. Government Higher Education Policies There have existed numerous reforms in the British education system over the years to accommodate better learning environments. These reforms have been targeted to solve impending constraints on the educational system. There have emerged problems in the standards of school performance with low school attendanc e leading to poor skills in the overall working population. These problems have developed to present discrepancy in higher education system where most individuals are lowly motivated to boost their overall performance. In 1980s, an experienced slow growth in educational progress among individuals especially below 16years led to the ranking of the country among poor performers. This system saw a conservative policy implementation where the government, involved parents in policymaking and articulated their financial status from number enrolled (Hill, 2001, 3). This system further promoted a public revealing of student’s result that enabled parents compare results and performance of different schools. The government sought to these systems to improve the results and general individual performance. The government of the 1980s had been conservative and exposed the inequalities in the system that existed among several schools. Secondly, there existed a problem in poor depiction of working skills especially among the younger working individuals in the UK market. The government sought to solve this problem through introducing a curriculum that applied uniformly across individuals especially in their early learning ages. This policy to maintain equal curriculum implementation was further improved in the 1990s. This saw an introduction of a system that encourages teachers especially in

Factors Affecting the Performance of Employees Research Paper

Factors Affecting the Performance of Employees - Research Paper Example The human resource policies and strategies of an organization are the key determinants of employees’ performance (Armstrong, 2006). For example, in my previous employment, there were various incentives such as Christmas bonuses to employees, which aimed at motivating employees. Despite the human resource policies and strategies, the interrelationships of various departments of the organization, inter-organizational relations, and demographic factors have an impact on employees’ performance. According to Armstrong (2006), human resources are valuable assets for an organization. Understanding the issues, which influence worker performance, may be key to enhancing employee’s productivity and morale. Organizations formulate strategies for providing an excellent work environment in order to attract and retain the best employees. These strategies should address those factors that affect the performance of workers. These factors may be within or outside the company, inc luding those factors emanating from the employee’s personal lives. The paper will discuss the following factors as determinants of employees’ performance. These factors include ability, knowledge and skills, feedback, environment, standards, and motivation.  Ã‚  Motivation is the key to an effective organization to sustain the stability of the work in a strong way and help the survival of the organization. Motivation is discovering a requirement inside the workers and assisting to attain it. Motivation enables employees to widen their skills to meet the organizational objectives. Motivation drives human beings to achieve their objectives and company objectives through each challenge and limitation they experience in their workplace. The need of accomplishment leads in a desire to put extra effort to have something done better and the desire for success. There are three internal forces that influence an individual’s behavior; direction, intensity, and persisten ce. In terms of direction, motivation is directed by objectives while in terms of intensity, it is the amount of effort allotted. In terms of persistence, it is the time and effort applied. The following are the five main approaches of motivation; Maslow’s need hierarchy theory, Adams’ equity theory, Vroom’s expectancy theory, Herzberg’s two-factor theory, and Skinner’s reinforcement theory (Herzberg, 1987). Maslow points out that there are five levels of employee needs; safety, physiological, ego, social, and self-actualizing. Maslow observed that employees are motivated when their low-level needs are satisfied first before the next high-level needs. Herzberg’s study classified motivation into two factors; hygiene and motivators. Intrinsic or motivator factors, such as recognition and achievement lead to job satisfaction. Extrinsic or hygiene factors, such as level of remuneration and degree of job security generate job dissatisfaction. Vro om’s approach is based on the idea that worker effort will result in performance, which will result in rewards. The rewards can be either negative or positive. The more positive the prize the more probable the worker will be extremely motivated (Armstrong, 2006). On the contrary, the more negative the prize, the less probable the worker will be motivated.  Ã‚  

Manufacturing Technology lab Report Example | Topics and Well Written Essays - 1500 words

Manufacturing Technology - Lab Report Example The first order of business was to machine the chamfer. The chamfer was created using a High Speed Steel (HSS) tool through tapered turning using the taper turning attachment. The tapering operation was measured for consistency to ensure that the angle or the dimensions were not exceeded beyond the drawing recommended levels. Next, the portion of the job, with the largest diameter was held inside the chuck. The next operation was to rough up the stock billet using the single point tool along with acceptable feed rates and depths of cut. The cutting speed for aluminum is recommended as 75-105 meters per minute (Smith & Peterson, 2008). The rotational speed of the lathe chuck was determined using the formula shown below: In a similar manner, the feed rate was required for determining how fast the piece would be fed to the lathe machine. Two different feed rates were used, one for roughing operations and one for finishing operations (Fox Valley Tech, 2014). The chosen feed rate for roughing was 0.65 mm per minute while the finishing rate chosen was 0.20 mm per minute. The entire stock billet was roughed out in the first series of operations, after which it was measured to determine how much finishing would be required. The finishing operations were carried out to create a stepped piece which would further require an external grooving operation and a chamfering operation on one end. The next operation was creating an external groove. This groove was created using a finer finishing tool with a much slower cutting speed and feed rate to contain accuracy. Once the external groove was machined into place, and measured for consistency at four different points on the circumferential surfaces of the groove, the piece was faced to size. The facing was carried out with the same finishing tool. The final step was to create a M8 thread on the 8mm diameter portion of the job. The piece was centered

Muscle Strength Assessment Essay Example | Topics and Well Written Essays - 1250 words

Muscle Strength Assessment - Essay Example Consider that the minute diameter afferent impacts efferents, hence, sensitivity of the muscle spindle and likely resulting to proprioceptive acuity that may not be attributed to the exhausted muscle. This could take place in different areas in the exercise region and likewise, contra laterally (Pedersen, 1999). Though, it is claimant that the clinicians must delay the process of the joint position sense evaluation because of the fatigue state, unless the assessment of the proprioceptive effects of fatigue is deliberate, it shows that there were no report about the presumptive effects of exercise that are non-exhausting. Even so, extreme non-exhausting exercises, like the strengthening and muscle evaluation, are likely to produce the said metabolic results that keeps the possibility of acute effects on the micro trauma in the spindle muscles, spindles of the muscle and changed in the neurone excitability of the spinal neurone. The chance to evaluate the effe... sults that keeps the possibility of acute effects on the micro trauma in the spindle muscles, spindles of the muscle and changed in the neurone excitability of the spinal neurone. The chance to evaluate the effects of the strength of the thigh muscle on the joint sense, most especially during sports activities, directs to the collaboration of research study with other groups who also wants to study the same subject. The joint position sense evaluation result on both knees was already published in by Stillman in 1998. Justification for Proprioceptive Treatments In 1996 Sports Medicine and Musculoskeletal Surgery, Joerosch & Prymka specified that: "In conservative therapy more focus should be put on exercising the proprioceptive capability. In surgical therapy we should identify procedures which not only restore the anatomy but also reconstruct the neurophysiological feedback mechanism. In preventive programmes, proprioceptive training should be included as well"(177). The similar observations were brought about by Safran and others, in 1994. In aid for the proceeding discussion, proprioceptive treatment pertain to any therapeutic operations that is assumed to rejuvenate, enhance or maintain proprioception. At present, however, it is still unknown if it yields. Moreover, surgeons have some grounds in the attempt of retaining much of the proprioceptively stimulated structures likely in the anterior cruciate ligament restoration and in the surgical replacement of the osteoarthritic joints ( Safran et al 1994, Insall et al 1981). Histological experimental studies in animals resulted in reconstituted mechanoreceptor in the reconstructed cruciate ligaments in the 6 to 12 months post operative ( Barrack et al 1997, Denti et al 1994, Tsujimoto et al 1993, Goertzen

The Effect of Smoking on the Heart Essay Example | Topics and Well Written Essays - 1500 words

The Effect of Smoking on the Heart - Essay Example In order to demonstrate the highly-addictive properties of smoking, one study followed a cohort of men who were diagnosed with an acute, largely fatal, disease diagnosis, and others who were diagnosed with chronic, smoking-related illness. While there was some reduction in smoking, and some cessation, this behavior was not universal. This article reviews further research that is needed in order to better tailor findings about smoking and cardiovascular (and other vascular) disease, in order to understand how it correlates to specific genomic types, and to better predict who might be most susceptible to heart disease. There is no more medical debate about whether smoking causes cardiovascular and other diseases. Despite the nearly-unanimous verdict of the medical community, the persistence of smoking behaviors requires a better understanding of who is most susceptible, and how smoking exactly affects health. Much of the research in the past has concentrated on "all-or-nothing" verdicts: non-smokers versus smokers. In fact, there are many smokers who may decide, on the basis of personal diagnoses, to reduce their smoking rather than quit altogether. New research has established that smoking reduction may have some advantages as compared to continuing to smoke at previous rates. The enThe entire science of genomics offers, in conjunction with new clinical studies, the opportunity to better track who is susceptible and who is less likely to contract smoking-related illnesses. New diagnostic techniques may offer the opportunity to track smoking-related illnesses more exactly, giving physicians new ways of identifying and tracking the course of smoking-related illnesses. LITERATURE REVIEW The evidence that smoking is related to heart disease has existed for several decades. Recent work has attempted to better understand the mechanisms by which smoking influences heart disease, and to vary the types of smoking exposure in order to determine degree of severity of cardiovascular damage and the amount and timing of smoking. According to Terry Martin, there are no "easy" or lighter ways to prevent the deleterious effect of smoking (Martin). Low-tar cigarettes are no better than regular cigarettes. In a useful overview of literature, Martin cites the National Cancer Institute's recent study which concludes that even light cigarettes "provide no benefit to smokers' health." The Journal of the American College of Cardiology (JACC) concluded that, while smoking increases the chances of contracting heart disease, smoking cessation can lengthen one's quality of life-years, but not to the same extent as if one had not smoked at all (Iso). This study, which was performed on Asians, found that the best benefits to reduction of heart disease occurred 10-14 years after cessation. Note that the Japanese population studied generally has a much lower rate of heart disease than Caucasians or African-Americans. One should be cautious, therefore, in tying these results to those expected with different populations. That there is a link is indisputable. For example, an article in the "Journal of Behavioral Medicine" in 2005 recounts the study of smokers from age

Professional Role Transition - Assignment Example Data sources that contained information related to the topic were also used during the research process. The studies presented evidences such as quoting those who were interviewed during the study. This showed that students were given equal opportunity to answer the questions directed at them. The studies also took a while to be completed. A slow research ensures that the researcher gains all the information required. Things tend to change with time and by conducting a research study within a long time, the researcher gets to record every change that may take place and also predict how the study will be in future. What I know about the journal is that it intends to understand the challenges that students face when transitioning into BN from LPN. The journal identifies all the challenges and helps to explain methods that can be used to curb them. The journals target LPN students who may be interested in studying BN. The study will help them understand the challenges they are bound to face. The journals also target other scholars that focus on studying the topic. These journals will give them a point of reference for their study. Educators in the institutions that the students enroll for BN are also a target audience for the study because they will have the knowledge of how to help the students adapt to the transition. Because of the challenges faced when transitioning from LPN to BN, students opt to turn to their mentors at their places of work to guide them. These mentors are in a great position to help them put into practice what they have studied. The journals have also helped explain why the LPNs choose to expand their knowledge. One of the reasons given by the participants is that at the work place, they are considered less of nursing practitioners and their opinions are not valued. Some of them had to endure being called Little Pretend Nurses instead of their real titles. For the students who have

Australian education trends Essay It is often known that education forms the backbone of economic development and growth in any nation. The investment in pre-school, primary and secondary education as well as community college education ensures availability of human capital endowed with relevant skills and knowledge for enhanced productivity. This has proven to be a necessity for sustained economic development in any country in the world. Educated people are in no doubt different from the uneducated or less educated in a variety ways (Tiffen, Gittins, 2004). At the outset, the difference is eminent in attitudes and behavior, in their well being and health status, income as well as values regarding morals, religion, politics and employment among others. By instilling these positive characteristics to individuals in the community, education has therefore transformed the world people live in from the old ignorance-ridden era to the technologically-advanced modern life (Tiffen, Gittins, 2004). Australia has experienced a steady increase in education levels in the last century. The government has in the past centralized funding of education and imposed high taxes on high income earners in an attempt to finance education. Students are not spared either in this plan and have been included in the â€Å"user pays† principle where they reimburse for the education services received. However, this scheme has affected education in many countries and how the government plans to implement the principle together with high taxation is a matter of concern. In Australia, the Government provides public funding for non-government schools as well as substantial assistance to government academic institution. Funding of state government schools is the primary responsibility of States and territories (Laporte, Ringold, 1997). These organs can also provide assistance to non-governmental institutions of learning. It is estimated that more than two thirds of the students in non-government academic institutions are affiliated to Catholic as a religion. Australian education system is a three tier model where children enroll in Kindergarten at the age of about five years, then graduate to primary followed by secondary levels from year one to twelfth year and finally tertiary education (Harrison, 2002). Education is mandatory for the children aged between five to about sixteen years but the federal government caters for the university education. This system has ensured a reduced school life expectancy thereby enhancing educational development in the country (Centre for Educational Research and Innovation, 2008). This however draws a sharp contrast to the old system. Australian education system was highly stratified and that only infants and primary education were provided for the children. Additionally, Selection for high school education was very competitive, and favored the siblings of specific people who used to be prominent in the society (Henry, 1990). These individuals included industrialists, agriculturalists as well as businessmen among other professionals. Teaching profession was undermined since the government offered low wages to the teachers in addition to subjecting them to strict laws that restricted their personal as well as professional conduct. These factors reduced the productivity of the teaching staff thereby suppressing students’ performance in schools (Henry, 1990). The tremendous increase in level of education in Australia has been largely attributed to changes in a variety of factors including social and institutional framework as well as economic changes and student financing much else besides (Evans Kelley, 2002). To start with, changes in educational levels have been associated with urbanization. The rural-urban migration brought about by the inadequacy of farmland as well as search for skilled jobs in the cities has enhanced the development of cities in Australia. This has therefore called for the provision of educational services in these highly populated regions hence increasing the educational levels. Evans Kelley (2002) estimates the changes brought about by urbanization to about six percent over the last century. Economic growth on the other hand has been articulated with the steady increase in the educational levels in Australia. This country has witnessed a considerable economic growth in the recent past. Australian GDP for instance is currently valued at 1050 billion dollars which is slightly above 1.6 percent of the world economy (Laporte, Ringold, 1997).   Australia has so far recorded steady economic growth and unlike other OECD nations it did not fall to the economic recession witnessed in the recent past (Organization for Economic Co-operation and Development, 2007). Moreover, the country has recorded a growth rate of about 3.6% annually for the last fifteen years. This has empowered the government hence its ability to fund education as well as other sectors (UNESCO/OECD World Education Indicators Program, 2005). It therefore implies that most of the Australians are able to access education compared to the past where parents used to dropout of school after compulsory education level. The current parents have therefore acquired high social status in addition to pursuing the available high skilled and well-paying professional jobs. The Australian children who hail from well educated families can now access proper education thereby increasing the levels of education in the country (Ruitenberg, 2010). Economic growth has therefore contributed to about twenty six percent education growths in Australia. This change has mainly improved education levels in both the primary education which is compulsory as well as secondary education which the educated and socially as well as economically-empowered parents can now afford (Evans Kelley, 2002).The duo however admit that the aforementioned factors only contribute to a little percentage of the sources of educational transformation so far witnessed in Australia and that the real sources of change in education trend in this century are still unclear. Youth participation in education including vocational education and training has also improved in Australia. According to Sue et al (2009) a variety of factors have influenced this upsurge in the education trends in Australia. Factors such as how the young people’s families as well as community value education, the socioeconomic status of the general population, available education and training and the school curriculum, existing policies on education and youth employment, financial incentives and obstacles, economic structure in regard to industry and occupation have changed hence improvement of youth participation in education and vocational training in Australia (Kilpatrick, Sue,  Baynes, Chapman Hazel An indexing term that provides specific identifying information in a category: geographic names, laws and legislation, or tests and testing., ()), 2009). Australia just like other developed States has recorded a steady decline in fertility rate which has brought about the ratio of two children per couple (Tiffen, Gittins, 2004). It is always presumed that the higher the number of children in a family the reduced ability of the parents to provide quality education to an individual child. This is because the available resources such as finance, energy and time are shared among the many children thereby reducing the amount received by an individual child (Evans Kelley, 2002). The reduced fertility rate in Australia has ensured reduced number of children in a family which the parents can afford to provide quality education for thus contributing to increased level of education in the country. These changes in education levels brought about by changes in family size are only noticeable in secondary schools and tertiary levels and not in primary level where the government funds education (Harrison, 2002). The government’s commitment to provide quality education has also influenced to a greater extent the steady growth in education levels so far witnessed in Australia. The Australian government has increased its spending on education of both males and females compared to the last century. There have been issues of gender inequality in education and females have been stereotyped as underperformers in the past (Evans Kelley, 2002). It is note worthy that in all countries except New Zealand; there have been lower performance by females than their male counterparts especially in mathematics literacy (Marginson, 1993). This traditional stereotype is being overcome by the Australian government through equal provision of educational services to both the sexes. Philosophers such as Martin Roland have also contributed to this issue of gender equality and education of the girl child. Roland argues that the old tradition was a barrier to the equal distribution of resources to both the sexes in the society since it discriminated against the females and favored the males. She reiterates that gender issues should be embedded in the curriculum as well as in teaching and schooling activities to ensure that the product of such a system is an ideal educated person. John Dewey is another renowned philosopher whose contribution to education, politics as well as philosophy has been globally recognized. According to Dewey, education was the cornerstone to intellectual development and progress of the society. He stressed on the improvement of moral and social nature of schools as an attempt to fostering democracy and community prosperity (Paringer, 1990). Dewey asserts that provision of education service to a single child in the society empowers the child towards self- effectiveness which consequently provides a guarantee to a lovely, worthy and harmonious society. Democracy never used to prevail in the ancient society as a result of lack of knowledge by then. According to Dewey, the nature of things should be viewed from a perspective of change and growth and therefore the continuous transformation in education is inevitable (Dewey, 2007). Nel Noddings is an additional prominent philosopher whose argument revolves around the moral reasoning, beliefs and values in education. She states that the current education trends encourages moral development hence the need to adopt educational structures that incorporates ethics and the use of motherly interest to inform moral learning. She however blames politics that fulfills the interests of particular groups for threatening the establishment of strong ethical foundation of learning as well as teaching in the academic institution (Palmer, Bresler, Cooper, 2001). Conclusion Education in Australia has undergone commendable changes since the first half of the last century. The Australian government as well as other stakeholders in the educational sector has contributed towards the social progress which is primarily dependent on the enhanced education standards in the country. Education has so far transformed from the old system characterized by repugnant traditions and values to the modern technologically- advanced era where education is the basic requirement for community sustainability. The progress in science and technology in the current era has created the knowledge and skills necessary for the developed industrial economy, while growth of education has provided workforce that is needed to utilize these new opportunities. Australia currently enjoys a socially-friendly environment with high paying professional jobs as well as improved living standards courtesy of development witnessed in the education sector.

Chapter 7: This chapter considers nuclear energy through certain areas which may be beneficial or not to Ireland. Chapter 8: This is the final chapter of the dissertation where the author reaches conclusions from the research carried out to date, followed by recommendations and areas for further study. Research Methodology Research may be defined as, the systematic study of materials and sources in order to establish facts and reach new conclusions (Concise Oxford English Dictionary 2005). This section outlines the research methods used to prepare this dissertation. The structure of this dissertation presents the findings of research, clearly identified, which was conducted by the author. Also aspects of data collection associated with problems encountered and limitations will be summarized. Research Process Preliminary research began during the Authors placement year (year 3 of BSc Construction Economics Management in Limerick Institute of Technology). As part of the year a dissertation proposal submission was required. An initial investigation on the availability of information was carried out and being satisfied that the information available was sufficient, I decided to continue with the topic. The initial sources primarily included books, Internet, papers and magazines. Research Planning For the research process consideration was given to the possible methods of approach to the actual dissertation. To carry out the research effectively and in a detailed manner a research plan and programme was established. This plan consisted of giving sufficient time for the detailed research of material both published and unpublished. From this the author got a detailed understanding of the topic and the exact focus of the dissertation was established along with the content and scope of the various chapters. After choosing the title, aim, objectives and hypothesis, a detailed plan had to be formulated to meet each objective of the dissertation. This proved vital to the success of the dissertation, given the limited time frame to review material, engender results and complete the dissertation. Due to the amount of publications and information that needed reviewing for inclusion into the dissertation file, reading and analysis was continuously ongoing. All articles of information were scanned generally to assess their suitability and all relevant information marked accordingly. All relevant information, once analysed, was categorized based on its relevance to a given chapter. Data Collection Methods In order to test the hypothesis of this dissertation effectively detailed information had to be sought on all aspects of renewable energies and the Irish energy market. The types of data used for compiling this dissertation came from both primary and secondary sources. Material from both sources was read in detail and any information relevant to any aspect of the dissertation topic was highlighted and noted. For the actual structure of the separate chapters, this information was subdivided into separate files for each proposed chapter. Primary Sources The dissertation utilized primary sources, as work contained provided accurate information. The volume of the information was obtained from Government organisations and EU reports. The up to date factor of the reports was its main advantage. Other organisations such as Sustainable Energy Ireland published reports which proved very beneficial. As the dissertation subject is topical at present, there have been many related conferences and the proceedings published. Official Government publications were helpful especially for information relating to the All Island Energy Market. Other official publications from the EU were used to gather information on EU Directives and the Kyoto Protocol. Finally structured interviews were conducted in relation to setting up and operating wind farms as the results offered accurate first hand information. Past dissertations have been utilized but for the purpose of guidance. Secondary Sources An in depth documentary review was undertaken by the author, which involved examining various sources of information for factual information. This information was taken from construction journals, textbooks, brochures and magazines. Text books were used only for background information. Magazines and national papers proved helpful in keeping up with new developments affecting the topic, for example the Budget and Government publications. As the dissertation required up to date information on the topic, a large quantity of information was obtained from the Internet. Limitations There were a number of difficulties encountered during the research of this dissertation. The main concern for the author was the realization that new information on the chosen topic was constantly being up dated with new developments. As the dissertation is somewhat based on what may happen in the future, the conclusions and recommendations are based on educated assumptions. There exists a lack of published work in relation to the All Island Energy Market, as the consultation period is still on going. Contact with the Department of Communications, Marine and Natural Resources was made with regard to the topic and all other topics relating to the dissertation. The author was informed that the most up to date information would be available in the Governments Energy White Paper 2007 Delivering a Sustainable Energy Future for Ireland and that information contained within it could not be released until the Governments official launch on the 12th of March 2007. Due to time constraints the author was not able to exploit this source. Based on the limited amount of information available the author utilized a significant amount of secondary sources. Also research questionnaires had to be abandoned due to a lack of response from organisations. Although certain information available was limited, with continued research and perseverance though all possible avenues it is believed that suitable material was compiled delivering a complete dissertation on the subject matter. CHAPTER TWO What Is Renewable Energy? Introduction Renewable energy comes from energy sources that are continuously replenished by nature. They are non-fossil energy sources that are not depleted by utilization. The main sources of renewable energy are the wind, the sun (solar energy), water (hydropower, wave and tidal energy) and biomass (wood, biodegradable waste and energy crops). Renewable energy sources are those which are effectively inexhaustible (such as wind, wave, solar, hydro etc) or which are replenished at or about their rate of consumption (such as managed forests and energy crops and other forms of biomass) (Anon 2005). What are the Benefits of Renewable energy? Renewable energy resources are clean sources of energy. They can be harnessed without damaging the environment, unlike using fossil fuels which release carbon dioxide (a greenhouse gas) and other harmful pollutants into the atmosphere. Increasing the use of renewable energy is therefore a key strategy for reducing greenhouse gas emissions and meeting Irelands Kyoto commitments. Renewable energy resources will not become exhausted. Unlike finite fossil fuels, renewable energy resources are continuously replenished and will not run out. Renewable energy resources are indigenous resources. Ireland is heavily reliant on imported fossil fuels. We now import around 89% of the fuels we need for energy. By tapping the renewable energy resources with which Ireland is richly endowed, we could reduce this reliance on imports. By increasing our use of renewable resources, we can achieve a more secure and stable energy supply for the long term (Sustainable Energy Ireland a). Chapter Summary Renewable energy generally refers to energy derived from non-fossil fuel resources (excluding nuclear). Renewable energy has become more popular in recent times as talks of global warming increase internationally and exhaustion of fossil fuels. Renewable energy will benefit the environment and help reduce our dependency on depleting sources of energy. CHAPTER THREE Irelands Potential Energy Needs Introduction To assess the potential of renewable sources sustaining Irelands energy needs in the future, firstly energy trends have to be evaluated to estimate the future requirements. It is impossible to know for sure what the future will hold but by reviewing different forecasts, a reasonable estimate can be made. Energy Trends Energy trends of the past fifteen years will give a good review of Irelands energy growth. It was within this time that the country experienced significant economic growth which was seen in the energy sector. The amount of energy consumed is shown through the Total Primary Energy Requirement (TPER). Total Energy Requirement (TER) figures represent the total Irish electricity generation at the plant exported level plus imports, less exports. The TER is the amount of electricity required to meet total final consumption in the Republic of Ireland including an allowance for transmission and distribution losses (Anon 2005). Figure 3.1 shows the Total Primary Energy Requirement (TPER) of the Republic of Ireland, broken down by fuel type, over the period 1990 to 2000. Estimates for the period 2001 to 2010 are also included. This figure shows that there was rapidly increasing growth in energy demands in the 90s and in particular, the mid 90s to 2000. It also shows a high dependence on the oil and gas. Energy Forecasts The Government document, All-Island Energy Market: Renewable Electricity A 2020 Vision; Preliminary Consultation Document, (Anon 2005), forecasts energy demands by firstly modifying the 2005 2011 median TER values so as to account for generation plant house load, and then determining the values for 2012 2020 at the assumed growth rates of 3% per annum between 2012 and 2015, and of 2% per annum between 2015 and 2020. This can be clearly seen in Table 3.1. These facts are based on the future for the whole island of Ireland, a joint north and south venture of meeting future energy demands and include Northern Ireland which is discussed in Chapter Six. The above forecast is not alone in believing that there will be a steady growth, although slightly less over a longer period of time. The report (Howley et al 2006) assumes electricity demand to grow significantly. Table 3.2 from the report shows the predicted growth. The prediction assumes the CO2 costs â‚ ¬15/tonne in 2010 and â‚ ¬30/tonne in 2020. Chapter Summary The past energy trends showed that there has been a constant rise in energy demand and this is reflected in the forecasts. The two different reports predicted to 2020 and show a similar prediction. It can then be assumed that to 2010 a 3.0 4.0% increase can be expected and from 2010 2020, a lesser 1.0 2.0%. The forecast for the generating fuel is predicted through past trends and present economic development, predicting oil to be eliminated by 2010 and gas to dominate. Although renewables are predicted to increase, early forecasts report they will only have a minor impact. CHAPTER FOUR Why a Renewable Energy Future? Introduction The future of Irelands energy supply is changing and it can not be stopped but we can adapt. The foremost important issue for the Government is to secure the countries future energy supply. Irelands geographical location and fuel resources means it is of critical importance that the future energy supply is secured now before it is too late. Ireland is too dependant on import fossil fuels for energy and so we need to become more independent, which renewable energy can provide. While Irelands imports of fossil fuels for energy still stand at about 85 per cent, much higher than the EU average of 50 per cent, there is a definite shift towards renewables. But there are other factors steering Ireland towards renewable sources, including EU and Kyoto responsibilities. Oil and Gas Depletion Oil and gas are a finite resource and there so going to completely run out some day. The demand for gas and in particular oil is increasing. This is mainly due to significant economic growth of China and India. The report Exxon-Mobils view of the future of oil and gas predicts demand is expected to rise through the year 2010 at a rate of about 2 per cent per year for oil and 3 per cent per year for gas (Longwell), as shown in Figure 4.1. This is leading to a rise in price, Figure 4.2, which already is affecting Ireland. As stated in the EU Green Paper in 2006, Oil and gas prices are rising. They have nearly doubled in the EU over the past two years, with electricity prices following. This is difficult for consumers. With increasing global demand for fossil fuels, stretched supply chains and increasing dependence on imports, high prices for oil and gas are probably here to stay (Anon 2006). Rising oil prices In its 2001 review BP commented The worlds oil R/P (reserve to production) ratio has fallen modestly since 1990 as world oil production growth has outpaced additions to reserves (Busby 2002). A chart in the 2001 review shows 1990 as the year when the R/P peak ratio of 44 was passed, reducing to 40 by the end of 2000. At the end of 2002 the R/P ratio had reduced further to 39, to rise to 41 at the end of 2003, dropping back to 40.5 at the end of 2004, but shown at 40.6 at the end of 2005. As production continues to rise and additions to reserves fail to match it, the ratio of oil reserves to production (R/P) will continue to decline and the price of crude oil will rise. The world gas R/P ratio in 2005 was 65.1, compared to 40.6 for oil. At 2005 production rates, gas reserves would provide a source of energy for a further 24 years after oil exhaustion. But when oil supplies starts to run out, more gas will be used as a substitute, hence increasing gas depletion. So if oil production peak is predicted at 2010, gas production peak should follow bout the year 2020. The problem starts to become apparent when you realise the decline of oil discovery, as shown in Figure 4.3. The gap between discovery and consumption is widening and this will eventually lead to oil production peaking. Chevron, one of the worlds largest oil companies, admits to the imminent peak and decline of oil. An Oil production peak before or by 2010 seems now to be generally accepted. The not so distant future of Irelands energy market will then have to contend without oil. The oil market is global where the gas market is regional and this is where Ireland could really suffer in the long term. It is predicted that gas will outlast oil but gas has to be piped and Irelands geographical location causes problems. The discovery of the Corrib gas field is potentially very important as it offers temporary relief from increasingly unreliable supplies of gas from the United Kingdom and Europe, says Colin Campbell, petroleum geologist (Campbell). In the near future with oil demand rising pushing up prices and in the distant future oil not been available, we must look to renewables now. The Corrib gas field is small and might get ten or more years out of it at the current rate of consumption but the Government should use this opportunity to draw on the gas to help support renewable energy. The Environment and EU Directive Irelands main source of energy is fossil fuels which produce vast quantities of CO2, add to climate change and which the EU intend to reduce. The emissions that are produced from burning fossil fuels are becoming more serious every year and a much discussed topic at national and international level. Climate Change and the Kyoto Protocol Fossil fuels constitute a significant repository of carbon buried deep under the ground. Burning them results in the conversion of this carbon to carbon dioxide, which is then released into the atmosphere. This results in an increase in the Earths levels of atmospheric carbon dioxide, which enhances the greenhouse effect and contributes to global warming (Wikipedia). As was seen in Figure 4.4, fossil fuels are a major electricity fuel for Ireland. Fossil fuels, particularly coal, contain a dilute radioactive material which is released into the environment leading to low levels of radioactive contamination. Within the EU burden sharing agreement to meet its obligation under the Kyoto Protocol, Ireland must stabilise its Greenhouse gas emissions at 13% above 1990 levels within the period 2008 to 2012 (Department of Communications, Marine and Natural Resources 1998). Intergovernmental Panel on Climate Change (IPCC) latest Assessment Report was released on the 2nd of February 2007 in Paris. The report was produced by some 600 authors from 40 countries. According to the IPCC, the warming of the world is unequivocal, and that humans are very likely (higher than 90% likelihood) behind the warming. The key conclusions were: Possible temperature rise between 1.1C and 6.4C by 2100 Sea level most likely to rise by 18-59cm (7in-23in) Artic summer sea ice disappears in second half of century Increase in heatwaves very likely Increase in tropical storm intensity likely Considering overall greenhouse gas emissions, energy related CO2 emissions accounted for 51% in 1990 compared to a projected 66% in 2010 if we continue in the same direction. Renewable energy would dramatically reduce Irelands CO2 emissions by replacing fossil fuels. This will take time, so if want to have any chance of meeting the requirements, we have to act now. EU Directive The use of renewable energy has a legislative basis in the EU under Directive (2001/77/EC). The Directive asserts the European Countries need to promote renewables to contribute to: †¦environmental protection and sustainable development. In addition this can also create local employment, have a positive impact on social cohesion, contribute to security of supply and make it possible to meet Kyoto targets more quickly'(Anon 2005). The directive forces Ireland to have an output of renewable powered electricity to 13.2% of total electricity consumed in Ireland by 2010. But the Government is hoping to have it up to 15% by 2010 through the Renewable energy Feed In Tariff (ReFIT) programme. The new Renewable energy Feed in Tariff (ReFIT) programme replaces the Governments previous support mechanism, the Alternative Energy Requirement (AER) programme and provides financial support of â‚ ¬119m to renewable energy projects over a fifteen year period The ReFIT programme will support the construction of an initial target of at least 400 megawatts (MW) of new renewable energy powered electricity generating plants. Its main aim is to increase the contribution of renewable energy sources to electricity production. The ReFIT programme will help make renewable energy competitive and is a move closer to reaching the Kyoto Protocol and the EU directive. Failure to meet the Kyoto Protocol and EU Directive (2001/77/EC) will have serious financial implications. On April 4th 2006 the European Commission launched legal proceedings against Ireland, for failing to meet the deadline of October 2003 for taking the necessary measures to transpose Community legislation on renewable electricity into national law. Ireland is now under pressure to act on renewable energy. Future Policies EU Leaders decided on Friday 9th of March 2007 to slash greenhouse gas emissions, which included a binding target for renewable sources to make up a fifth of EU energy use by 2020. The leaders committed to a target of reducing EU greenhouse gas emissions by 20 per cent by 2020 and offered to go to 30 per cent if major nations such as the United States, Russia, China and India follow suit. According to a draft agreement, the EU will aim to go even further in the future, with cuts of 60 to 80 per cent by 2050. Reports of drastic future climate change in the wake of the IPCCs recent assessment, talk of a post Kyoto agreement is been debated. The recent EU summit outcome of reducing greenhouse gas emissions by 20 per cent will form the basis of the EUs position in international talks to replace the U.N. Kyoto Protocol, which expires in 2012. Whatever it may be called, it will aim to severely reduce Greenhouse Gases to coincide with Global Warming reports. Either way it will mean a serious change for Governments and society. Chapter Summary The demand for gas and in particular oil is increasing largely due to the economic growth of China and India. The reserves at the moment show gas will outlast oil. Oil production is predicted to peak around 2010 but as oil resources decrease, demand for gas will increase to make up the slack which will result in gas production peaking sooner rather than later. The large growth in demand at present is increasing prices and with talk of oil production peaking and the politically unstable situation in the Middle East, prices look set to continue escalating. Renewable energy can help Ireland reduce its dependence on imported fossil fuels. Irelands main energy source, fossil fuels, is seriously damaging the environment and the main cause of Global Warming. The Kyoto Protocol requires Ireland to reduce its CO2 emissions. Under EU legislation Ireland must increase the use of renewable energy to 13.2% of all electricity produced but the Government are aiming for 15% with the announcement of the ReFIT programme. The programme will help meet Kyoto and EU obligations. Recent announcement from the EU requires 20% of the EUs electricity generation mix be from renewable sources by 2020. This ambitious target will require serious consideration from the Government. CHAPTER FIVE The Renewable Energy Options for the Future Introduction To meet the future energy demands, the Government will have to put a lot more work into developing renewable sources of energy. The positive from this, is Ireland has vast potential for renewable energy production, especially wind. Although the Government are starting to take more notice of renewable energy technology. Within Budget 2007 Brian Cowan stated scheme of tax relief in place in the form of a deduction from a companys profits for corporate investment in renewable energy products in the solar, wind, hydro or biomass technology categories, shall be continued for a further five years, subject to EU approval (Cowan 2006). But when considering renewable energy options, it is important to realistically assess their full potential. The present renewable energy sources should be looked at in a view of their output and efficiency, then evaluate their future part in securing the countrys energy supply. Wind Power Wind power is one of the most mature renewable energy technologies to date and currently has a good record of reliability and availability. The wind resources in Ireland are among the best in the EU due to the strength of the Atlantic winds. A wind turbine in Ireland will deliver twice as much power as the same turbine in Germany. We are the envy of Europe because of our wind speeds (Seanad Éireann 2005). Wind energy has seen major advances in Ireland recently, especially in the last four years. Wind energy now has the largest installed capacity of all renewable energy technologies in Ireland (Figure 5.1). As per up to date statistics from EirGrid, there is currently a total of 744 MW worth of wind power connected to the main grid and an additional 547.3 MW worth of energy from contracted wind farms currently in production to be connected at various stages in the future. (See Appendix C and Appendix D) Renewable Connections Kinetic energy in airflows is used to run wind turbines; some are capable of producing 5 MW of power, but the most cost effective are currently 500 kW 1.5 MW. Conventional investment costs are about â‚ ¬1,100 per kW installed. Wind energy has been growing significantly over recent years and following the trend, wind power will keep going in the near future, Figure 5.2. Wind Generation since 1992 to 2007 Onshore Wind Onshore wind in Ireland is mainly concentrated on the west coast due to strong winds from the Atlantic. Wind-speed maps help decide on the locations by showing the wind potential of certain areas but sites close to the western sea shore is generally the best region, as with Tursillagh Wind Farm. (Example of Analysis of Wind Potential See Appendix E) Turbines at Tursillagh Winds in an area are often monitored for a year and detailed maps constructed prior to wind generators being installed. Coastlines tend to be the windiest sites for turbines, because a primary source of wind is convection from the differential heating and cooling of land and sea. The erection of a wind farm onshore is becoming straight forward with companies having gained much experience and knowledge. Ireland has had well developed onshore wind energy for many years and has the knowledge to develop bigger wind farms to help meet the countries energy demand. Offshore Wind The offshore electricity production in Ireland is minimal but has made a good start. Arklow Offshore Wind Power Plant is the worlds first offshore project to deploy giant wind turbines in excess of 3megawatts and is Irelands only offshore wind project. But already is showing great prospect, showing excellent reliability and availability, areas where wind power is mainly criticised. The site was chosen as tests proved to be one of the windiest areas in Europe. Offshore turbines cause less aesthetic controversy as usually can not be seen from the shore. It offers fewer obstacles and stronger winds but is also more inaccessible and the conditions are harsh, corrosive and can increase the costs of maintenance. Unlike with onshore wind farms, planning is not an issue. The biggest obstacle at present is the significant capital cost even compared to onshore wind. Irelands offshore potential is an untapped resource and must be harnessed to become a serious contributor to the Irish electricity mix. Offshore wind power generation should be recognised for what it is; Irelands best option for meeting present renewable energy and CO2 targets. Planning for the Future To promote wind as one of the major sources of electricity in the future, it can be beneficial to look at a similar EU country with a successful wind market, for example Denmark. The ESB system is comparable in size to the west Denmark Eltra system. The Transmission System Operator (TSO) in Ireland, ESB National Grid (ESB NG), has asked for a report, explaining the management of the western Danish system Eltra with a focus on handling of wind production (Hilger 2004). This shows the level of interest in the Danish system for wind. The ESB has spotted the potential of assessing Denmarks approach to wind for our own future development. Denmark has only modest wind speeds, compared to Irelands impressive wind energy potential. As can be seen in the Case Study (Appendix F), the key to Denmarks wind power success is the support from the interconnectors to other EU countries. Winds intermittence problem is compensated with bought in electricity from the Nordic power pool at the going rate. The major interest in Denmarks Eltra system for the future will come from Denmarks offshore development, in particular the Horns Rev Wind Park. The Horns Rev Wind Park is a show case of Danish initiative in the large scale promotion of renewable energy. Horns Rev is the largest offshore wind farm in the world, producing two per cent of Denmarks total energy consumption. Much can be learned from Horns Rev in planning the future of wind power generation in Ireland. The offshore turbines produce 150 per cent more electricity than land based turbines. Also Denmarks offshore areas are restricted but the Irish situation is a decentralised approach where the pick of areas is open for private initiative. The Horns Rev project was a result of fourteen years of research and initiated by the Danish Government which was the main factor for its commencement. The turbines used (Vestas V80) which can adapt the output of the turbine to suit the parameters of any electricity grid. Although a lot of p lanning and research went into Horns Rev, construction only took six months which was run through the summer months for improved weather conditions. And finally so successful was Horns Rev, an additional wind farm (Horns Rev 2) is to be built northeast of the existing farm. The new offshore wind farm and the landing facilities will be commissioned in May 2009.

Research Methodology Research may be defined as, the systematic study of materials and sources in order to establish facts and reach new conclusions (Concise Oxford English Dictionary 2005). This section outlines the research methods used to prepare this dissertation. The structure of this dissertation presents the findings of research, clearly identified, which was conducted by the author. Also aspects of data collection associated with problems encountered and limitations will be summarized. Research Process Preliminary research began during the Authors placement year (year 3 of BSc Construction Economics Management in Limerick Institute of Technology). As part of the year a dissertation proposal submission was required. An initial investigation on the availability of information was carried out and being satisfied that the information available was sufficient, I decided to continue with the topic. The initial sources primarily included books, Internet, papers and magazines. Research Planning For the research process consideration was given to the possible methods of approach to the actual dissertation. To carry out the research effectively and in a detailed manner a research plan and programme was established. This plan consisted of giving sufficient time for the detailed research of material both published and unpublished. From this the author got a detailed understanding of the topic and the exact focus of the dissertation was established along with the content and scope of the various chapters. After choosing the title, aim, objectives and hypothesis, a detailed plan had to be formulated to meet each objective of the dissertation. This proved vital to the success of the dissertation, given the limited time frame to review material, engender results and complete the dissertation. Due to the amount of publications and information that needed reviewing for inclusion into the dissertation file, reading and analysis was continuously ongoing. All articles of information were scanned generally to assess their suitability and all relevant information marked accordingly. All relevant information, once analysed, was categorized based on its relevance to a given chapter. Data Collection Methods In order to test the hypothesis of this dissertation effectively detailed information had to be sought on all aspects of renewable energies and the Irish energy market. The types of data used for compiling this dissertation came from both primary and secondary sources. Material from both sources was read in detail and any information relevant to any aspect of the dissertation topic was highlighted and noted. For the actual structure of the separate chapters, this information was subdivided into separate files for each proposed chapter. Primary Sources The dissertation utilized primary sources, as work contained provided accurate information. The volume of the information was obtained from Government organisations and EU reports. The up to date factor of the reports was its main advantage. Other organisations such as Sustainable Energy Ireland published reports which proved very beneficial. As the dissertation subject is topical at present, there have been many related conferences and the proceedings published. Official Government publications were helpful especially for information relating to the All Island Energy Market. Other official publications from the EU were used to gather information on EU Directives and the Kyoto Protocol. Finally structured interviews were conducted in relation to setting up and operating wind farms as the results offered accurate first hand information. Past dissertations have been utilized but for the purpose of guidance. Secondary Sources An in depth documentary review was undertaken by the author, which involved examining various sources of information for factual information. This information was taken from construction journals, textbooks, brochures and magazines. Text books were used only for background information. Magazines and national papers proved helpful in keeping up with new developments affecting the topic, for example the Budget and Government publications. As the dissertation required up to date information on the topic, a large quantity of information was obtained from the Internet. Limitations There were a number of difficulties encountered during the research of this dissertation. The main concern for the author was the realization that new information on the chosen topic was constantly being up dated with new developments. As the dissertation is somewhat based on what may happen in the future, the conclusions and recommendations are based on educated assumptions. There exists a lack of published work in relation to the All Island Energy Market, as the consultation period is still on going. Contact with the Department of Communications, Marine and Natural Resources was made with regard to the topic and all other topics relating to the dissertation. The author was informed that the most up to date information would be available in the Governments Energy White Paper 2007 Delivering a Sustainable Energy Future for Ireland and that information contained within it could not be released until the Governments official launch on the 12th of March 2007. Due to time constraints the author was not able to exploit this source. Based on the limited amount of information available the author utilized a significant amount of secondary sources. Also research questionnaires had to be abandoned due to a lack of response from organisations. Although certain information available was limited, with continued research and perseverance though all possible avenues it is believed that suitable material was compiled delivering a complete dissertation on the subject matter. CHAPTER TWO What Is Renewable Energy? Introduction Renewable energy comes from energy sources that are continuously replenished by nature. They are non-fossil energy sources that are not depleted by utilization. The main sources of renewable energy are the wind, the sun (solar energy), water (hydropower, wave and tidal energy) and biomass (wood, biodegradable waste and energy crops). Renewable energy sources are those which are effectively inexhaustible (such as wind, wave, solar, hydro etc) or which are replenished at or about their rate of consumption (such as managed forests and energy crops and other forms of biomass) (Anon 2005). What are the Benefits of Renewable energy? Renewable energy resources are clean sources of energy. They can be harnessed without damaging the environment, unlike using fossil fuels which release carbon dioxide (a greenhouse gas) and other harmful pollutants into the atmosphere. Increasing the use of renewable energy is therefore a key strategy for reducing greenhouse gas emissions and meeting Irelands Kyoto commitments. Renewable energy resources will not become exhausted. Unlike finite fossil fuels, renewable energy resources are continuously replenished and will not run out. Renewable energy resources are indigenous resources. Ireland is heavily reliant on imported fossil fuels. We now import around 89% of the fuels we need for energy. By tapping the renewable energy resources with which Ireland is richly endowed, we could reduce this reliance on imports. By increasing our use of renewable resources, we can achieve a more secure and stable energy supply for the long term (Sustainable Energy Ireland a). Chapter Summary Renewable energy generally refers to energy derived from non-fossil fuel resources (excluding nuclear). Renewable energy has become more popular in recent times as talks of global warming increase internationally and exhaustion of fossil fuels. Renewable energy will benefit the environment and help reduce our dependency on depleting sources of energy. CHAPTER THREE Irelands Potential Energy Needs Introduction To assess the potential of renewable sources sustaining Irelands energy needs in the future, firstly energy trends have to be evaluated to estimate the future requirements. It is impossible to know for sure what the future will hold but by reviewing different forecasts, a reasonable estimate can be made. Energy Trends Energy trends of the past fifteen years will give a good review of Irelands energy growth. It was within this time that the country experienced significant economic growth which was seen in the energy sector. The amount of energy consumed is shown through the Total Primary Energy Requirement (TPER). Total Energy Requirement (TER) figures represent the total Irish electricity generation at the plant exported level plus imports, less exports. The TER is the amount of electricity required to meet total final consumption in the Republic of Ireland including an allowance for transmission and distribution losses (Anon 2005). Figure 3.1 shows the Total Primary Energy Requirement (TPER) of the Republic of Ireland, broken down by fuel type, over the period 1990 to 2000. Estimates for the period 2001 to 2010 are also included. This figure shows that there was rapidly increasing growth in energy demands in the 90s and in particular, the mid 90s to 2000. It also shows a high dependence on the oil and gas. Energy Forecasts The Government document, All-Island Energy Market: Renewable Electricity A 2020 Vision; Preliminary Consultation Document, (Anon 2005), forecasts energy demands by firstly modifying the 2005 2011 median TER values so as to account for generation plant house load, and then determining the values for 2012 2020 at the assumed growth rates of 3% per annum between 2012 and 2015, and of 2% per annum between 2015 and 2020. This can be clearly seen in Table 3.1. These facts are based on the future for the whole island of Ireland, a joint north and south venture of meeting future energy demands and include Northern Ireland which is discussed in Chapter Six. The above forecast is not alone in believing that there will be a steady growth, although slightly less over a longer period of time. The report (Howley et al 2006) assumes electricity demand to grow significantly. Table 3.2 from the report shows the predicted growth. The prediction assumes the CO2 costs â‚ ¬15/tonne in 2010 and â‚ ¬30/tonne in 2020. Chapter Summary The past energy trends showed that there has been a constant rise in energy demand and this is reflected in the forecasts. The two different reports predicted to 2020 and show a similar prediction. It can then be assumed that to 2010 a 3.0 4.0% increase can be expected and from 2010 2020, a lesser 1.0 2.0%. The forecast for the generating fuel is predicted through past trends and present economic development, predicting oil to be eliminated by 2010 and gas to dominate. Although renewables are predicted to increase, early forecasts report they will only have a minor impact. CHAPTER FOUR Why a Renewable Energy Future? Introduction The future of Irelands energy supply is changing and it can not be stopped but we can adapt. The foremost important issue for the Government is to secure the countries future energy supply. Irelands geographical location and fuel resources means it is of critical importance that the future energy supply is secured now before it is too late. Ireland is too dependant on import fossil fuels for energy and so we need to become more independent, which renewable energy can provide. While Irelands imports of fossil fuels for energy still stand at about 85 per cent, much higher than the EU average of 50 per cent, there is a definite shift towards renewables. But there are other factors steering Ireland towards renewable sources, including EU and Kyoto responsibilities. Oil and Gas Depletion Oil and gas are a finite resource and there so going to completely run out some day. The demand for gas and in particular oil is increasing. This is mainly due to significant economic growth of China and India. The report Exxon-Mobils view of the future of oil and gas predicts demand is expected to rise through the year 2010 at a rate of about 2 per cent per year for oil and 3 per cent per year for gas (Longwell), as shown in Figure 4.1. This is leading to a rise in price, Figure 4.2, which already is affecting Ireland. As stated in the EU Green Paper in 2006, Oil and gas prices are rising. They have nearly doubled in the EU over the past two years, with electricity prices following. This is difficult for consumers. With increasing global demand for fossil fuels, stretched supply chains and increasing dependence on imports, high prices for oil and gas are probably here to stay (Anon 2006). Rising oil prices In its 2001 review BP commented The worlds oil R/P (reserve to production) ratio has fallen modestly since 1990 as world oil production growth has outpaced additions to reserves (Busby 2002). A chart in the 2001 review shows 1990 as the year when the R/P peak ratio of 44 was passed, reducing to 40 by the end of 2000. At the end of 2002 the R/P ratio had reduced further to 39, to rise to 41 at the end of 2003, dropping back to 40.5 at the end of 2004, but shown at 40.6 at the end of 2005. As production continues to rise and additions to reserves fail to match it, the ratio of oil reserves to production (R/P) will continue to decline and the price of crude oil will rise. The world gas R/P ratio in 2005 was 65.1, compared to 40.6 for oil. At 2005 production rates, gas reserves would provide a source of energy for a further 24 years after oil exhaustion. But when oil supplies starts to run out, more gas will be used as a substitute, hence increasing gas depletion. So if oil production peak is predicted at 2010, gas production peak should follow bout the year 2020. The problem starts to become apparent when you realise the decline of oil discovery, as shown in Figure 4.3. The gap between discovery and consumption is widening and this will eventually lead to oil production peaking. Chevron, one of the worlds largest oil companies, admits to the imminent peak and decline of oil. An Oil production peak before or by 2010 seems now to be generally accepted. The not so distant future of Irelands energy market will then have to contend without oil. The oil market is global where the gas market is regional and this is where Ireland could really suffer in the long term. It is predicted that gas will outlast oil but gas has to be piped and Irelands geographical location causes problems. The discovery of the Corrib gas field is potentially very important as it offers temporary relief from increasingly unreliable supplies of gas from the United Kingdom and Europe, says Colin Campbell, petroleum geologist (Campbell). In the near future with oil demand rising pushing up prices and in the distant future oil not been available, we must look to renewables now. The Corrib gas field is small and might get ten or more years out of it at the current rate of consumption but the Government should use this opportunity to draw on the gas to help support renewable energy. The Environment and EU Directive Irelands main source of energy is fossil fuels which produce vast quantities of CO2, add to climate change and which the EU intend to reduce. The emissions that are produced from burning fossil fuels are becoming more serious every year and a much discussed topic at national and international level. Climate Change and the Kyoto Protocol Fossil fuels constitute a significant repository of carbon buried deep under the ground. Burning them results in the conversion of this carbon to carbon dioxide, which is then released into the atmosphere. This results in an increase in the Earths levels of atmospheric carbon dioxide, which enhances the greenhouse effect and contributes to global warming (Wikipedia). As was seen in Figure 4.4, fossil fuels are a major electricity fuel for Ireland. Fossil fuels, particularly coal, contain a dilute radioactive material which is released into the environment leading to low levels of radioactive contamination. Within the EU burden sharing agreement to meet its obligation under the Kyoto Protocol, Ireland must stabilise its Greenhouse gas emissions at 13% above 1990 levels within the period 2008 to 2012 (Department of Communications, Marine and Natural Resources 1998). Intergovernmental Panel on Climate Change (IPCC) latest Assessment Report was released on the 2nd of February 2007 in Paris. The report was produced by some 600 authors from 40 countries. According to the IPCC, the warming of the world is unequivocal, and that humans are very likely (higher than 90% likelihood) behind the warming. The key conclusions were: Possible temperature rise between 1.1C and 6.4C by 2100 Sea level most likely to rise by 18-59cm (7in-23in) Artic summer sea ice disappears in second half of century Increase in heatwaves very likely Increase in tropical storm intensity likely Considering overall greenhouse gas emissions, energy related CO2 emissions accounted for 51% in 1990 compared to a projected 66% in 2010 if we continue in the same direction. Renewable energy would dramatically reduce Irelands CO2 emissions by replacing fossil fuels. This will take time, so if want to have any chance of meeting the requirements, we have to act now. EU Directive The use of renewable energy has a legislative basis in the EU under Directive (2001/77/EC). The Directive asserts the European Countries need to promote renewables to contribute to: †¦environmental protection and sustainable development. In addition this can also create local employment, have a positive impact on social cohesion, contribute to security of supply and make it possible to meet Kyoto targets more quickly'(Anon 2005). The directive forces Ireland to have an output of renewable powered electricity to 13.2% of total electricity consumed in Ireland by 2010. But the Government is hoping to have it up to 15% by 2010 through the Renewable energy Feed In Tariff (ReFIT) programme. The new Renewable energy Feed in Tariff (ReFIT) programme replaces the Governments previous support mechanism, the Alternative Energy Requirement (AER) programme and provides financial support of â‚ ¬119m to renewable energy projects over a fifteen year period The ReFIT programme will support the construction of an initial target of at least 400 megawatts (MW) of new renewable energy powered electricity generating plants. Its main aim is to increase the contribution of renewable energy sources to electricity production. The ReFIT programme will help make renewable energy competitive and is a move closer to reaching the Kyoto Protocol and the EU directive. Failure to meet the Kyoto Protocol and EU Directive (2001/77/EC) will have serious financial implications. On April 4th 2006 the European Commission launched legal proceedings against Ireland, for failing to meet the deadline of October 2003 for taking the necessary measures to transpose Community legislation on renewable electricity into national law. Ireland is now under pressure to act on renewable energy. Future Policies EU Leaders decided on Friday 9th of March 2007 to slash greenhouse gas emissions, which included a binding target for renewable sources to make up a fifth of EU energy use by 2020. The leaders committed to a target of reducing EU greenhouse gas emissions by 20 per cent by 2020 and offered to go to 30 per cent if major nations such as the United States, Russia, China and India follow suit. According to a draft agreement, the EU will aim to go even further in the future, with cuts of 60 to 80 per cent by 2050. Reports of drastic future climate change in the wake of the IPCCs recent assessment, talk of a post Kyoto agreement is been debated. The recent EU summit outcome of reducing greenhouse gas emissions by 20 per cent will form the basis of the EUs position in international talks to replace the U.N. Kyoto Protocol, which expires in 2012. Whatever it may be called, it will aim to severely reduce Greenhouse Gases to coincide with Global Warming reports. Either way it will mean a serious change for Governments and society. Chapter Summary The demand for gas and in particular oil is increasing largely due to the economic growth of China and India. The reserves at the moment show gas will outlast oil. Oil production is predicted to peak around 2010 but as oil resources decrease, demand for gas will increase to make up the slack which will result in gas production peaking sooner rather than later. The large growth in demand at present is increasing prices and with talk of oil production peaking and the politically unstable situation in the Middle East, prices look set to continue escalating. Renewable energy can help Ireland reduce its dependence on imported fossil fuels. Irelands main energy source, fossil fuels, is seriously damaging the environment and the main cause of Global Warming. The Kyoto Protocol requires Ireland to reduce its CO2 emissions. Under EU legislation Ireland must increase the use of renewable energy to 13.2% of all electricity produced but the Government are aiming for 15% with the announcement of the ReFIT programme. The programme will help meet Kyoto and EU obligations. Recent announcement from the EU requires 20% of the EUs electricity generation mix be from renewable sources by 2020. This ambitious target will require serious consideration from the Government. CHAPTER FIVE The Renewable Energy Options for the Future Introduction To meet the future energy demands, the Government will have to put a lot more work into developing renewable sources of energy. The positive from this, is Ireland has vast potential for renewable energy production, especially wind. Although the Government are starting to take more notice of renewable energy technology. Within Budget 2007 Brian Cowan stated scheme of tax relief in place in the form of a deduction from a companys profits for corporate investment in renewable energy products in the solar, wind, hydro or biomass technology categories, shall be continued for a further five years, subject to EU approval (Cowan 2006). But when considering renewable energy options, it is important to realistically assess their full potential. The present renewable energy sources should be looked at in a view of their output and efficiency, then evaluate their future part in securing the countrys energy supply. Wind Power Wind power is one of the most mature renewable energy technologies to date and currently has a good record of reliability and availability. The wind resources in Ireland are among the best in the EU due to the strength of the Atlantic winds. A wind turbine in Ireland will deliver twice as much power as the same turbine in Germany. We are the envy of Europe because of our wind speeds (Seanad Éireann 2005). Wind energy has seen major advances in Ireland recently, especially in the last four years. Wind energy now has the largest installed capacity of all renewable energy technologies in Ireland (Figure 5.1). As per up to date statistics from EirGrid, there is currently a total of 744 MW worth of wind power connected to the main grid and an additional 547.3 MW worth of energy from contracted wind farms currently in production to be connected at various stages in the future. (See Appendix C and Appendix D) Renewable Connections Kinetic energy in airflows is used to run wind turbines; some are capable of producing 5 MW of power, but the most cost effective are currently 500 kW 1.5 MW. Conventional investment costs are about â‚ ¬1,100 per kW installed. Wind energy has been growing significantly over recent years and following the trend, wind power will keep going in the near future, Figure 5.2. Wind Generation since 1992 to 2007 Onshore Wind Onshore wind in Ireland is mainly concentrated on the west coast due to strong winds from the Atlantic. Wind-speed maps help decide on the locations by showing the wind potential of certain areas but sites close to the western sea shore is generally the best region, as with Tursillagh Wind Farm. (Example of Analysis of Wind Potential See Appendix E) Turbines at Tursillagh Winds in an area are often monitored for a year and detailed maps constructed prior to wind generators being installed.

Offshore Wind The offshore electricity production in Ireland is minimal but has made a good start. Arklow Offshore Wind Power Plant is the worlds first offshore project to deploy giant wind turbines in excess of 3megawatts and is Irelands only offshore wind project. But already is showing great prospect, showing excellent reliability and availability, areas where wind power is mainly criticised. The site was chosen as tests proved to be one of the windiest areas in Europe. Offshore turbines cause less aesthetic controversy as usually can not be seen from the shore. It offers fewer obstacles and stronger winds but is also more inaccessible and the conditions are harsh, corrosive and can increase the costs of maintenance. Unlike with onshore wind farms, planning is not an issue. The biggest obstacle at present is the significant capital cost even compared to onshore wind. Irelands offshore potential is an untapped resource and must be harnessed to become a serious contributor to the Irish electricity mix. Offshore wind power generation should be recognised for what it is; Irelands best option for meeting present renewable energy and CO2 targets. Planning for the Future To promote wind as one of the major sources of electricity in the future, it can be beneficial to look at a similar EU country with a successful wind market, for example Denmark. The ESB system is comparable in size to the west Denmark Eltra system. The Transmission System Operator (TSO) in Ireland, ESB National Grid (ESB NG), has asked for a report, explaining the management of the western Danish system Eltra with a focus on handling of wind production (Hilger 2004). This shows the level of interest in the Danish system for wind. The ESB has spotted the potential of assessing Denmarks approach to wind for our own future development. Denmark has only modest wind speeds, compared to Irelands impressive wind energy potential. As can be seen in the Case Study (Appendix F), the key to Denmarks wind power success is the support from the interconnectors to other EU countries. Winds intermittence problem is compensated with bought in electricity from the Nordic power pool at the going rate. The major interest in Denmarks Eltra system for the future will come from Denmarks offshore development, in particular the Horns Rev Wind Park. The Horns Rev Wind Park is a show case of Danish initiative in the large scale promotion of renewable energy. Horns Rev is the largest offshore wind farm in the world, producing two per cent of Denmarks total energy consumption. Much can be learned from Horns Rev in planning the future of wind power generation in Ireland. The offshore turbines produce 150 per cent more electricity than land based turbines. Also Denmarks offshore areas are restricted but the Irish situation is a decentralised approach where the pick of areas is open for private initiative. The Horns Rev project was a result of fourteen years of research and initiated by the Danish Government which was the main factor for its commencement. The turbines used (Vestas V80) which can adapt the output of the turbine to suit the parameters of any electricity grid. Although a lot of p lanning and research went into Horns Rev, construction only took six months which was run through the summer months for improved weather conditions. And finally so successful was Horns Rev, an additional wind farm (Horns Rev 2) is to be built northeast of the existing farm. The new offshore wind farm and the landing facilities will be commissioned in May 2009. (See Appendix F, Case Study) Constraints of Wind P
