Recommended: Advantages & disadvantages of nuclear energy
The great physicist Albert Einstein once said, “A new type of thinking is essential if mankind is to survive and move to higher levels.” He understood the importance of exploiting novelties to create something beneficial for mankind. No one demonstrates this way of thinking better than Einstein because he had the boldness to explore fields of science that few have ever approached in order to make the world a better place. Today, human society faces the detrimental consequence of global warming due to pollution from fossil fuel combustion; the world once again needs to discover never-before-seen alternatives. These alternatives may be risky in certain ways, but for mankind to prosper and continue to survive, these risks are necessary. One alternative to fossil fuel is nuclear energy, a recent innovation that is still fairly uncommon in producing power. Clearly, nuclear energy should play a greater role in powering the world because it possesses environmental, viable, and political incentives. Nuclear energy has significant environmental advantages over conventional energy sources. One prime example is the comparison of the effects of fossil fuel versus nuclear energy on global warming. When examining pollution, an important factor is a power plant’s carbon dioxide (CO2) emission. Using nuclear power could significantly slow global warming because it produces much less CO2 than fossil fuel. For example, a 1,250 megawatt coal-fired power plant releases 11.8 million tons of CO2 per year; a nuclear power plant of similar magnitude releases merely 0.5 million tons (McLeish 37). This means nuclear energy produces less than 5% the emission as coal energy! However, people may doubt the impact of global warming.

Overall, the environmental, practical, and political benefits all make nuclear energy the ideal source to power the world. No matter what critics say or believe, the advantages of nuclear energy far outweigh any disadvantages. Despite the fact that people probably wish to immediately increase nuclear power plants, achieving the ultimate goal to combat pollution or foreign leverage will require time. Fortunately, by choosing nuclear energy, the American public will have taken a step toward the future to create more innovative features that will benefit everyone. As the world continues to advance, people will need to take risks that can lead to better lives. Whether the positive results are immediate or not, taking risks will definitely pave the way for improvement and success.
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.
Almost every single nation in our world today, the United States included, is extremely reliant on oil and how much of it we can obtain. Wars have been started between countries vying for control of this valuable natural resource. The United States as a whole has been trying to reduce its reliance on foreign oil and has had some success, especially with the discovery of the Bakken formation and projects like the Keystone Pipeline.
...gy can successfully replace oil. Just as oil will not run out overnight, its replacement will be equally gradual. The success of this transition is largely contingent on time management. Presently, there is no nation privy to a miracle solution. A bulk of available alternative energy sources are not self sufficient, and require oil to jump start their production. Solar panels, while a step in the right direction, are built in factories, shipped in trucks, flown in planes dependent on oil. Oil needs to be conserved, reserved solely for uses that will benefit future generations, such as creating green energy products. As long as there exists a shadow of a doubt as to the inevitability of peak oil, the existence of debate serves not only as an obstacle, but as a cause for hope. When everyone is forced to acknowledge the peak oil issue, it may very well be too late.
Central Idea: Nuclear energy only contributes a small amount to the world’s electricity yet it has hazards and dangers that far out-way its benefits. There are many other alternative power producing sources that can produce energy more efficiently and more safely than nuclear power plants can.
After the United States developed the atomic at the end of World War II, interest in nuclear technology increased exponentially. People soon realized that nuclear technology could be used for electricity, as another alternative to fossil fuels. Today, nuclear power has its place in the world, but there is still a lot of controversy over the use of nuclear energy. Things such as the containment of radiation and few nuclear power plant accidents have given nuclear power a bad image. However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer.
The United States has had several scares throughout its history in terms of oil, most turn out to be over exaggerations of a small event. However, these scares highlight a massive issue with the U.S. and that issue is the U.S.’s dependence on foreign oil. Why does it matter that our oil should come from over seas? In a healthy economy this probably wouldn’t be as relevant, but the U.S.’s economy is not exactly healthy at the moment. There are 4 things that I would like to address: what the problem is, how it affects us, what some solutions are, and what solutions I feel are best.
The world is facing an energy crisis and many are unaware of this growing problem. Sustainability is avoiding depletion of our natural resources in order to provide for future generations, and the only way to ensure that resources are available into the future is to find alternative sources to meet the world’s energy needs. Nuclear energy is just one source of alternative energy being implemented today in an effort to support the needs of the population and mitigate global climate change. Nuclear energy holds the necessary benefits in order to continue being used globally as an alternative solution.
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.

According to the US Environmental Protection Agency, over half of the oil used in the USA is imported. Most of this imported oil is located in the middle east and is controlled by OPEC members. Subsequent oil price shocks and price manipulation by OPEC have cost our economy dearly—about $1.9 trillion from 2004 to 2008—and each major shock was followed by a recession (Reduce). We may never be able to fully eliminate our need to import oil, but we can reduce cartel market control and the economic impact of price shocks by reducing our demand (Reduce). One way we can reduce our reliance on oil is through investing in renewable energy. Solar power, wind power, and hydro power are all forms of energy which come from renewable resources. Unlike oil, solar, wind and hydro electric power is abundant and can be obtained locally.
The use of nuclear power in the mid-1980s was not a popular idea on account of all the fears that it had presented. The public seemed to have rejected it because of the fear of radiation. The Chernobyl accident in the Soviet Union in April of 1986 reinforced the fears, and gave them an international dimension (Cohen 1). Nevertheless, the public has to come to terms that one of the major requirements for sustaining human progress is an adequate source of energy. The current largest sources of energy are the combustion of coal, oil, and natural gas. Fear of radiation may push nuclear power under the carpet but another fear of the unknown is how costly is this going to be? If we as the public have to overcome the fear of radiation and costly project, we first have to understand the details of nuclear energy. The known is a lot less scary then the unknown. If we could put away all the presumptions we have about this new energy source, then maybe we can understand that this would be a good decision for use in the near future.
Prevent dangerous climate change by phasing out fossil fuels (oil, coal, gas) and replacing them with clean renewable energy such as solar.
To remain competitive and employable in the twenty-first century workplace, society today must conform to the changing demands. Technology is one of the principal driving forces of the future; it is transforming our lives and shaping our future at rates unprecedented in history, with profound implications, which we cannot even begin to see or understand.
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
