What is Nuclear energy?
Utilizing nuclear reactions to generate electricity is known as nuclear power. Nuclear fission, nuclear decay, and nuclear fusion reactions can all provide nuclear energy. Currently, nuclear power plants use the fission of uranium and plutonium to generate the great majority of the world's electricity from nuclear sources.
The only significant, carbon-free electricity source that the nation can extensively expand to produce significant amounts of electricity is nuclear energy. When fossil fuels are burned to produce the same amount of electricity, nuclear power plants avoid producing a sizable amount of emissions.
