Sustainable Energy provides about 25% of the worlds energy needs and, without nuclear energy, global warming and the release of carbon dioxide and other noxious gases into the atmosphere would be more severe. France has led the way with about 80% of its power generated from its nuclear power stations. However, many other countries use nuclear power as an important component in a diverse mix of energy sources. Finland, Japan, Belgium, USA, South Korea and China all have substantial civil nuclear programmes.
