How Nuclear Power Works at Nuclear Power Now

Nuclear power plants provide about 17 percent of the world's electricity. Some countries depend more on nuclear now power for electricity than others. In France, for instance, about 75 percent of the electricity is generated from nuclear power, according to the International Atomic Energy Agency. In the United States, nuclear power supplies about 15 percent of the electricity overall, but some states get more power from nuclear plants than others. There are more than 400 nuclear power plants around the world, with more than 100 in the United States.

Introductory tutorial on how nuclear power works can be found at Nuclear Power Technology, Nuclear energy is, in many places, competitive with fossil fuel for electricity generation ( Nuclear Power Economics ) and The History of Nuclear Power Safety A chronology of nuclear safety research and development ( Nuclear Power Safety ).

The United States produces the most nuclear energy, with nuclear power providing 20% of the electricity it consumes, while France produces the highest percentage of its electrical energy from nuclear reactors—80% as of 2006. In the European Union as a whole, nuclear energy provides 30% of the electricity.Nuclear energy policy differs between countries, and some countries such as Austria and Ireland have no active nuclear power stations.
