context_page_description: Nuclear power is the controlled use of nuclear energy. Nuclear energy is energy in 'fissionable' elements like uranium that can be released by nuclear reactions in a machine called a nuclear reactor. This energy is made into electricity, which then can be used to power machines and heat homes. In 2007, 14% of the world's electricity came from nuclear power. Nuclear power plants also make radioactive waste that could be harmful if it is not stored properly.
  People have also been studying since the middle 20th century to use fusion power which produces much more energy and doesn't produce radioactive waste. Nuclear fusion reactors don't exist yet and are still being developed.
