A popular movement against nuclear power has gained strength in the Western world, based on concerns about more nuclear accidents and concerns about nuclear waste. Anti-nuclear critics see nuclear power as a dangerous, expensive way to boil water to generate electricity. The 1979 Three Mile Island accident and the 1986 Chernobyl disaster played a key role in stopping new plant construction in many countries. Major anti-nuclear power groups include Friends of the Earth, Greenpeace, Institute for Energy and Environmental Research, Nuclear Information and Resource Service, and Sortir du nucléaire (France).
