...To begin, I would keep Three Mile Island open because of all the good effects. Although T.M.I. had a disaster in the past, I would still keep it open. This is a two way argument, whether or not to keep T.M.I. open or not. In the paragraphs below I will state my opinion of why it should be kept open. Nuclear energy is the only form of energy that significantly replaces fossil fuels. Fossil fuels are nonrenewable and can’t be replaced. Also Nuclear power is considered renewable, although it uses a product (Uranium-235) which is nonrenewable. This type of power also powers 20% of the US. This may not seem like a lot, but Nuclear power has only been used for 70 years, unlike fossil fuels for hundreds of years . Another reason to consider is...

...Engineering Date: 13.03.2014 Submitted to: Engin ALKAN EFFECTS OF NUCLEAR ENERGY In our world, the energy is the most essential issue today. The more energy we have, the more we produe. In order to get some energy we need sources like nuclear power which harmful for the world. There are several reasons such as money, safety and failures for this. Firs of all, producing energy from nuclear power is very expensive. Although it seems the best way to generate energy, the fuel itself is expensive. Moreover, building and operating power plants are not cheap at all. Hiring workers and the crews of engineers and scientist is neccessary. Beside that, the teams need a training program. Plus, the conditions need to be safe for people who workk there and live in the city or country that they work in. Hiring, training and making the conditions safe means money. Secondly, most of the nuclerr materials are not safe. The nuclear fuels which are used in the power staations are dangerous. Mining fuels is also dangerous because it has radioactive gas. Workers may be effected unless they are fully proteccted from the radioactive gas. Every nuclear energy stations have it’s own waste products which are also not secure. Thet are very dabgerıys abd şt şs dşffşcykt tı dispose of or store safely. Thirdly, it is possible to accure any accidents. For instane, nuclear power plants can fail, whic is happened in Three Mile Island, U.S.A. ın 1979, Tarpur India in 1992 and Dorlington Canada in 1992...

...electricity for heat and light . The only practical short term solution for the energy-crisis is nuclear power. Nuclear power, however is not as safe as burning coal, gas or oil in a factory it is in fact, much more dangerous, There are dangers associated with a nuclear power plant which far out weigh the benefits to society as a whole and in part to the community living and working around the power plant . About 20 percent of our nation's total electrical consumption per year is supplied by nuclear power from the 100 or so nuclear power plants throughout the country . Even though atomic power has been in use for over 50 years it was primarily a tool of war and destruction when the war ended need for atomic bombs diminished . The scientists who created the weapons were out of jobs . They then turned this destructive power into huge plants generating "clean and cheap " electricity for the country . It was called progress. Progress also brought with it sickness , mutations , cancer and eventually death to those exposed to high levels of radiation . Government declared that nuclear power is safe and efficient . Also have big Oil corporations who have a lot of money invested in nuclear power and want to see as many plants as possible put into and kept in operation . The truth is that accidents do happen at nuclear power plants and at other facilities all the time . An accident at a nuclear power plant has the potential to be much more devastating than an accident...

...Europe’s energy security: challenges and opportunities GAWDAT BAHGAT Several geopolitical and economic developments in the first decade of the twentyfirst century have heightened Europe’s sense of vulnerability in respect of its energy supplies. On the supply side of the energy equation, the continuous fighting and rising ethnic and sectarian tension in Iraq, and the diplomatic confrontation over Iran’s nuclear programme, have intensified concern over the stability of supplies from the Persian Gulf. On the demand side, China’s and India’s skyrocketing energy consumption and their efforts to secure supplies have intensified global competition over scarce hydrocarbon resources. These changes in the landscape of the global energy market, in conjunction with diminishing refinery capacity, shrinking spare capacity and a low level of investment, have driven oil and natural gas prices higher. Currently, the European Union’s oil bill (for imported and domestically produced oil) stands at around €250 billion a year, or roughly 2.3 per cent of gross domestic product (GDP).1 These soaring prices have exerted tremendous pressure on European economies and underscored the need for a common European energy policy. The dispute between Russia and Ukraine over natural gas prices in January 2006 further highlighted the risks of dependence on a few energy suppliers. In early 2005 the Russian state monopoly, Gazprom, announced plans to start applying ‘market rules’ in its gas dealings with former Soviet...

...With the rapid advancement in wind technology, reliable product quality and more than 95% feasibility rates, wind power has become a safe and reliable energy source. With ever-increasing economization of generating electricity using wind power, the costs are becoming comparable to that for coal-fired generators and are lower than petroleum-fired and nuclear generators. Taking into account the intermediary investments in environmental protection and transportation, it is more economical to use wind power in place of coal to generate electricity. In addition, the construction of wind power stations takes a relatively shorter amount of time. The installation and adjustment of a wind turbine system takes a few weeks, and the whole process of land construction, installation and commencement of productions will only take 6 months to one year – a feat which coal-fired or nuclear stations cannot match up to. The investment scope is also flexible; one can chose to install as much capacity as possible based on the available capital. For offshore islands, remote highlands which are inaccessible, vast but thinly-populated grasslands and pastures, and rural villages and frontier regions which are far away from power supply networks and will continue to remain unreached, wind power can be an effective energy source for production and survival, which further enhances its significance. bad aspects The spinning blades kill and maim birds and bats Noise like "brick wrapped in a towel turning...

...Global Warming The atmosphere is something that is around us everyday, but do we really think about the changes that occur in it. It isn't that we just aren't paying attention, but more of the fact that it is hard to notice slight changes over long periods of time. Everyday gases are released into the air by all living material. The gases in the air are used for many important things. For example, hydrogen is released by volcanoes, which can give energy to the cell; photosynthesis has evolved to take the gas carbon dioxide and create food and release oxygen; nitrogen is a gas used in our air, oceans, and solid earth, as an essential part of living things. Carbon dioxide is also involved in processes where it is stored as limestone and marble, as gas and oil and coal, and is in organic material in the soil. Not only do these gases make up our atmosphere, but they also keep the temperature of the earth stable. Carbon dioxide absorbs the radiation that would otherwise escape the earth. By adding oxygen and taking away carbon dioxide this causes the earth to be cooler than it would otherwise be. These are just two of the many gases that make up the atmosphere we live in today. The temperature in our earth is directly determined by these five gases. If not enough are in the air, then the earth is too cold, but if too many gases are released into the air, then we have the problem of things heating up. Even though the causes of global warming are known, the exact...

...Renewable Energy Sources The Sustainability Revolution John C. Ayers "In a sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to us. Plants capture solar energy directly through photosynthesis. Fossil fuels contain the energy of sunlight captured hundreds of millions of years ago. Photovoltaic (PV) cells also capture sunlight energy directly. Other energy sources capture the energy of sunlight indirectly. Heat from the sun powers the flowing air and water. We usually capture the kinetic energy of wind and water by using turbines that transfer the energy to an alternator, an electrical generator that produces alternating current. Geothermal energy is different in that it captures flowing heat energy produced by radioactive decay in the earth’s interior. In this chapter we will see that Wind, Water, and Sun (WWS) energy sources are sustainable because they are renewable, clean, safe, and nearly carbon-free. Although they have low energy densities, meaning that they require large areas of land or water to produce energy, they are...

...power embodying global strategic thinking means that it must expand its maritime strategy by developing its navy and preparing for armed confrontation in terms of international relations realism. Conversely, Beijing’s maritime policy leads at the same time towards globalization, which involves multilateralism and strategic coexistence of a more pragmatic kind. This research analyses Chinese maritime strategy in the Asia-Pacific by asking: ‘Whither the Chinese maritime strategy in the ever changing Asia-Pacific security environment since the PRC was established in 1949?’ In general, contemporary China’s national security strategy is closely connected with its maritime strategy and with its comprehensive security plan for its economy, its energy supplies and its...

...JAPAN’S CULTURE JAPAN’S CULTURE History Japan has a very colorful history filled with rulers such as samurai warriors and emperor kings. The samurai warrior ruled Japan in the twelfth century and was a distinctive social class. The samurai tradition was mainly about war. The samurai tradition consisted of singling out a worthy opponent for a challenge. They would wait until enemy lines were broken and then enter into single combat. People began to develop battlefields to fight and would have battles several times to establish territory. (Clode, 2011) This was the beginning of the fighting and war that continued in Japan for centuries to come. Throughout Japan’s history it saw the rise and fall of many emperors that ruled the country. Through most of the history of Japan they had a policy that their borders were locked to the outside world and they did not allow foreigners in their country. This same policy applied to the Japanese people and they were not allowed to leave the country. The early emperors in Japan ruled the country by engaging in wars and the country was primarily run as an imperial and military rule. (Facts About Japan, 2013) After many years of declaring war on countries in nineteen thirty seven Japan declared war on China. This war led to the nineteen forty two attack that Japan launched in the United States on Pearl Harbor. After almost eight years of war atomic bombs were dropped on Japan bringing this war to an end. After Japan surrendered...

NASCAR Tries to Restart Its Engine ASCAR is widely known as the most popular spectator sport in the United States. Yet even its most diehard fans are tapping the brakes when it comes to buying tickets to their favorite speedway. Tracks in cities such as Phoenix and Talladega have reported double-digit percent declines in attendance. Just as worrisome is the fact that, instead of watching races at home, fans are changing the channel. Some critics of NASCAR blame a drop in dramatic action and a mandated car chassis design that leaves car models undifferentiated. Others say that the races are just too long and the broadcast commentary is boring. But NASCAR defenders argue that there’s another huge obstacle: the...
