Nuclear energy can also be freed in two other ways: nuclear fusion and nuclear fission. Nuclear fusion is the combining of two light atoms into a heavier one and nuclear fission is the splitting of a heavy atom. Both ways make big amounts of energy. They sometimes take place in nature. Fusion is the source of heat in the sun. Fission is also used in nuclear power plants to make electricity. Both fusion and fission can be used in nuclear weapons.

Nuclear energy production and use has been a controversial topic over the years. This has always been dictated by the history of the nuclear energy and also on the current energy demands as well as environmental conservation demands. Countries should venture into nuclear energy production to help meet the rising energy demand, to help conserve the environment by avoiding pollution, and also as a long lasting replacement for the depleting fossil fuels sources of energy. There have been mitigation measures put in place to ensure that nuclear energy accidents like those of Chernobyl and Fukushima do not have a repeat. Countries should also cease from using the nuclear energy to make dangerous weapons of mass destruction.
