where is nuclear energy used most in the world
United States France

This is a little more than the combined global electricity production from wind, solar, biomass and geothermal power, which together provided 2% of global final energy consumption in 2014. In addition, there were approximately 140 naval vessels using nuclear propulsion in operation, powered by about 180 reactors. Nuclear power's share of global electricity production has fallen from 16.5% in 1997 to about 10% in 2017, in large title: Nuclear power text: electricity in 2017, equivalent to about 10% of global electricity generation. As of April 2018, there are 449 civilian fission reactors in the world, with a combined electrical capacity of 394 gigawatt (GW). Additionally, there are 58 reactors under construction and 154 reactors planned, with a combined capacity of 63 GW and 157 GW, respectively. Over 300 more reactors are proposed. Most of reactors under construction are of generation III reactor design, with the majority in Asia. There is a social debate about nuclear power. Proponents, such as the World Nuclear Association and Environmentalists for Nuclear Energy, contend that nuclear title: Nuclear power by country text: Nuclear power by country Nuclear power plants currently operate in 31 countries. Most are in Europe, North America, East Asia and South Asia. The United States is the largest producer of nuclear power, while France has the largest share of electricity generated by nuclear power. In 2010, before the Fukushima Daiichi nuclear disaster, it was reported that an average of about 10 nuclear reactors were expected to become operational per year, although according to the World Nuclear Association, of the 17 civilian reactors planned to become operational between 2007 and 2009, only five actually came on stream. Global nuclear electricity title: Worldwide energy supply text: Wyoming 11%, Pennsylvania 8%, W Virginia 5% and Oklahoma 4%. In the Mid-East the Persian Gulfstates Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia and the Arab Emirates produce most. A small part comes from Bahrain, Jordan, Lebanon, Syria and Yemen. The top producers in Africa are Nigeria (254), S-Africa (167), Algeria (138) and Angola (100). In the EU France (138, mainly nuclear), Germany (120), UK (119), Poland (68, mainly coal) and Netherlands (48, mainly natural gas) produce most. Of the world renewable supply 1319 is biofuel and waste, mostly in developing countries, 334 is generated with hydro power and 200 title: Nuclear technology text: release energy for work including propulsion, heat, and the generation of electricity. Nuclear energy is produced by a controlled nuclear chain reaction which creates heat—and which is used to boil water, produce steam, and drive a steam turbine. The turbine is used to generate electricity and/or to do mechanical work. Currently nuclear power provides approximately 15.7% of the world's electricity (in 2004) and is used to propel aircraft carriers, icebreakers and submarines (so far economics and fears in some ports have prevented the use of nuclear power in transport ships). All nuclear power plants use fission. No man-made fusion reaction
