No energy-related technology is completely 'risk free'and unlimited demands on energy increase this risk factor many -fold .All energy use creates heat and contributes to atmosperic temperature.In addition,many forms of energy release carbon dioxide and lead to global warming .Nuclear energy family plants have caused enormous losses to the environment due to the leakage of nuclear meterial .The inability to effectively manage and safely dispose of nuclear waste is serious global warm
