Nuclear

The first commercial plant was built in 1957, and as of 2008 [9] there were 443 nuclear power plants in the world, with an installed capacity of 365 GW (production, 2,659 TWH; 2006 data) and 104 plants in the United States (installed capacity, 106 GW; production, 788 TWH). They provide around 15% of global electricity, with the largest percentage being France at 78%. The United States has not built any new nuclear plants in a number of years, and the percent of the U.S. electricity has declined from 23 to 20% as new electric plants are primarily fired by natural gas (Table 2.3).
