Introduction
To reduce the GHGs emissions and resolve the climate change is still a challenge, while the world is going to facing the running out of fossil fuels energy, yet the demand of energy keep increasing in these years. One efficient approach to solve the problem is to switch to the renewable energy or, nuclear energy indeed. The more people are hold against nuclear energy science the accident in Fukushima 2011, with stronger supporting to develop the renewable energy.
Compare to the renewable energy, the nuclear powers are used widely for decades with mature and applicable technology. Overall, more than 400 nuclear power plants operating in 30 countries, produced 2620 billion kWh, which supply 13.5% of the world’s electricity in year 2010 (T.N.&T.S., 2012). China decided to turn to nuclear power instead of natural gas and fossil fuel to meet the national electricity expansion – “mainland China has 20 nuclear power reactors in operation, 28 under construction, and more about to start construction”, says World Nuclear Association (2014).
Yet, the raw material of generate nuclear electricity, the uranium, is nonrenewable resource, and the nuclear plants brings negative impacts to the environment, which the essay elaborates below.
Discussion
Rationales of nuclear power
Nuclear energy, also known as atomic energy, became popular in the early 20th century. The atom held enormous capacity of energy - the uranium (uranium-238 and uranium-235) is formed into solid ceramic pellets packaged into long, vertical tubes for uses. In the reaction, the pellets are bombarded with neutrons, which causing the uranium atoms to split and release heat and neutrons, then the neutrons collide with other uranium atoms and release additional heat ...

Energy is undoubtedly one of the most important issues facing the world today. While fossil fuels may produce enough energy at a low cost, it also has severe environmental impacts on the world. Wind energy is a clean source, but is also extremely expensive to maintain. Nuclear energy may be the best energy alternative to coals and oil, with the ability to produce much more energy with relatively low cost, while also being more environmentally sound.
One of the many benefits of Nuclear energy is that it is completely emission free, in fact, more than 70% of the clean energy produced in the United States comes from nuclear (“11 Facts about Nuclear Energy”) With those lack of emissions we will see a reduction in the
Nuclear power has no place in having a safe, clean, sustainable future. Today, the manufacturing of nuclear power plants has become a critical topic throughout the world that many strongly believe should be stopped. Nuclear Power is not safe anywhere in the world nor is it environmentally friendly. Nuclear power plants are truly something that could cause mass destruction in the world and has the potential to wipe out a whole country with ease. Despite proponents’ that claim that nuclear power is safe, there is a history that proves otherwise and marks a number of disasters caused by nuclear power plants.
I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...

Although nuclear energy may emit less carbon dioxide as compared to oil or gas, it is nowhere near the alternative energy source we need. A Huffington Post article showed that water shortages, exacerbated by global climate change, minimizes the ability for expansion of nuclear power plants. As the generators require large amounts of water to keep them cool, they must be built on large water sources, mostly rivers and lakes. This reliance on water severely limits the places the nuclear power plants could be built, which makes nuclear an unreliable resource to replace oil and gas in the future as it could not meet all our energy needs. Furthermore, in 2009, France was forced to shut down many of their power plants due to the unseasonably warm summer it had, most likely caused by climate change. As our Earth continues to heat up and more places experience drought, nuclear energy is less and less reliable due to the reliance on cold water. Additionally, runoff from the water flows into nearby water sources, causing thermal pollution to the animals and ecological consequences. Coupled with the fact that we still have no idea how to properly dispose of the waste material left behind from nuclear reactions, nuclear power is not the alternative energy that solves major world problems. This hurts future generations, as we will not only create yet another reliance on an energy source that harms the planet, but divert attention away from truly solving the issue on hand. A Bloomberg New Energy Finance report from early June projects that as early as 2028, solar energy can replace the oil and gas sector demands. The cost of projection would also decrease for both solar and wind energy by 66-71% within the next ten years as well. Solar and wind have considerably less risks to the environment and, regarding these as more possible
Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
A. Attention Material: Have you ever thought about energy? Where it comes from and how it powers things? Nuclear energy is one of the many types of energy sources in the world today. It is a non-renewable resource such as coal and natural gas. The first nuclear reactor ever created by man was built in December of 1942. The discovery of building a nuclear power plant was discovered over 150 years ago (Nuclear Power: Villain or Victim?, p. 15).
Nuclear energy has is an overall success and continues to be because it is a reliable, efficient energy source that produces minimal pollution. Although it is a efficient energy source, it is also a massive destructive force that has been used in the past and can be used in the future if not properly defended against. America today can learn from instances in the 20th century such as the atomic bomb drops, exploration of fusion reactions, the knowledge gained from the three mile island accident, and from espionage. Nuclear technology is basically that manipulation of atoms in their current state. Usually radioactive elements such as high-grade plutonium or uranium are used in order to create a massive radioactive reaction that have the potential to obliterate any object in its way leaving a lasting negative effect on the environment. Nuclear energy was mainly researched for the atomic bomb droppings that occurred in 1945 as a result of Japanese oppression during World War II. The science of atomic manipulation, atomic radiation, nuclear fission and nuclear fusion was first developed in 1895. Research began to significantly speed up when the government took a large interest in the destructive force that nuclear weapons had the potential to hold. The only reason that the world ever had the experience of nuclear energy was because of World War II and oppression. Nuclear Energy came with a price of thousands of lives, that were not rightfully taken, but without those lives lost, our world would be different today, and we continue to learn from the mistakes and from the successes that we have had with nuclear technology.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...

Though it might seem that the world’s energy supply is secure as of the present, this issue is something that is beginning to worry even the richest states. “Countries as far apart as South Africa and Tajikistan are plagued by power cuts and there have been riots in several nations because of disruptions to electricity” and “rich states [are] no longer strangers to periodic blackouts” (ElBaradei). If we look again at the breakdown of U.S. electricity generation by energy source, it is evident that nuclear power is the next most substantial chunk of energy generation, with other renewables weighing in far behind that. I believe this begs the question, why do we not expand nuclear power to encompa...
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
