Shop Nuclear Energy Pros and Cons As of today, nuclear energy is considered as one of the most environmentally friendly source of energy as it produces fewer greenhouse gas emissions during the production of electricity as compared to traditional sources like coal power plants. Nuclear fission is the process that is used in nuclear reactors to produce high amount of energy using element called uranium. It is the energy that is stored in the nucleus of an atom.
During the past 20 years more than 19, Russian warheads have been dismantled and processed to make fuel for U. In fact, during that period more than half the uranium fuel that powered the more than reactors in the U.
In addition to reducing the risk of nuclear war, U. They also avoided spewing soot and other air pollution like coal-fired power plants do and thus have saved some 1. If you replace these power plants with modern, safe nuclear reactors you could do a lot of [pollution reduction] quickly.
The world needs to drop its global warming pollution by 6 percent annually to avoid "dangerous" climate change in the estimation of Hansen and his co-authors in a recent paper in PLoS One. Nuclear future China leads the world in new nuclear reactors, with 29 currently under construction and another 59 proposed, according to the World Nuclear Association.
And China has not confined itself solely to the typical reactors that employ water and uranium fuel rods; it has built everything from heavy-water reactors originally designed in Canada to a small test fast-reactor. Yet, even if every planned reactor in China was to be built, the country would still rely on burning coal for more than 50 percent of its electric power—and the Chinese nuclear reactors would provide at best roughly the same Nuclear energy in north america essay of energy to the developing nation as does the existing U.
Plus, nuclear requires emissions of greenhouse gases for construction, including steel and cement as well as the enrichment of uranium ore required to make nuclear fuel or the downblending of uranium from nuclear weapons as in the case of the " Megatons to Megawatts " program.

Over the full lifetime of a nuclear power plant, that means greenhouse gas emissions of roughly 12 grams of CO2-equivalent per kilowatt-hour of electricity produced, the same as wind turbines which also require steel, plastics, rare earths and the like in their construction and less than photovoltaic panels, according to the U.
In other parts of the world nuclear has begun to dwindle. Japan may never restart its nuclear plants in the wake of the multiple meltdowns at Fukushima Daiichi following the earthquake and tsunami inwhich also soured public opinion in many parts of the world.
Germany still plans to eliminate nuclear power and even France has announced plans to reduce its reliance on reactors. A big problem is cost.
The construction of large nuclear power plants requires a lot of money to ensure safety and reliability. For example, for the U. One other idea to cut cost is to begin building smaller reactors of so-called modular design.
The Tennessee Valley Authority hopes to catalyze development of such reactors by installing one at its Clinch River site in Tennessee, former home of the U. That never-completed breeder reactor is part of a legacy of failed U. That said, nuclear reactors are beginning to get the kind of scientific attention not seen since at least the end of the cold war.
Alternative concepts have attracted funding from billionaires like Bill Gates. Even worse, a nuclear stall can lead to the construction of more coal-fired power plants, as happened in the U.
Hansen, for one, argues that abundant, clean energy is necessary to lift people out of poverty and begin to reduce greenhouse gas emissions from a swelling human population. Nuclear is one of the technologies available today—and with room for significant improvement and innovation.
But significant hurdles remain, not least the decades required for design, licensing and construction of even existing nuclear technologies, let alone novel ideas.
That may mean advanced nuclear power cannot contribute much to efforts to combat climate change in the near term, which leaves current reactor technology as the only short-term nuclear option—and one that is infrequently employed at the global scale at present.
In the same way, U. Russia retains an estimated 8, nuclear warheads —and the U. The problem of fission and climate change is equally stuck at present. But, as Hansen wrote in an additional assessment of his new analysis"Environmentalists need to recognize that attempts to force all-renewable policies on all of the world will only assure that fossil fuels continue to reign for base-load electric power, making it unlikely that abundant affordable power will exist and implausible that fossil fuels will be phased out.Our largest and best clean-air energy source is nuclear.
