Nuclear energy now is the world’s mainly useful form of energy. Energy are devolved and have been used from the fossils fuels and are still be used now, but it is not an option to use it in the future. So this turned that we have a nuclear power as the best choice. There are many positives to nuclear energy over fossil fuels such as less global warming effects. At this time nuclear power provides 6% of the world’s energy and about 14% of the world’s electricity. The best part of this nuclear power is generated from the U.S., Japan, and France.

To comparing nuclear energy to fossil fuels it’s simple to see why so much time is used to use nuclear energy. It has been long time since we used the fossil fuels and it would stay forever. The three major fossil fuels are coal, oil, and gas. Oil is usually used but when the oil price is expensive there is a way to find other alternatives. Before oil was the largest, coal was also a major supply of energy. Coal has a long history of use as an energy source. It was the fuel of the industrial revolution and although many other energy sources have replaced some of the applications in which coal was used; it still is an important fuel for electrical generation. (http://www.wou.edu). These three are energy sources in partial contribute. There is a way of human being takes a part to burn throughout them, and will never stay. It is not just impossible to realize energy that stays forever, doing so much to have some negative side effects.
Nuclear power is the use of sustained nuclear fission to generate heat and do useful work. Nuclear Electric Plants, Nuclear Ships and Submarines use controlled nuclear energy to heat water and produce steam, while in space, nuclear energy decays naturally in a radioisotope thermoelectric generator. Scientists are experimenting with fusion energy for future generation, but these experiments do not currently generate useful energy. (http://reference.canadaspace.com)
Fusion is defined as two small atoms combine to form a larger atom of a different element. Fission is defined as a large atom of one element is split to produce two smaller atoms of different elements. Nuclear fusion reactions have the potential to be safer and generate less radioactive waste than fission. These reactions appear potentially viable, though technically quite difficult and have yet to be created on a scale that could be used in a functional power plant. Fusion power has been under intense theoretical and experimental investigation since the 1950s. (http://reference.canadaspace.com)
Another use of nuclear energy is already being used in the medical field. Nuclear energy can be used to help treat cancer through radiotherapy. Small doses of radioisotope tracers...

Many scientists believed that nuclear power is the best source of energy to provide a large amount of energy in a short period time and take up less land than other alternative energy. For example, the world largest wind farm , Roscoe Wind Farm near Roscoe, Texas, power capacity is about 781.5 megawatts, which is equal to an average nuclear power plant’s output capacity. For Roscoe
