The world's highest energy consuming country, the us , has done little to promote renewable energy. Being one of the major emitters of heat trapping gases like carbon dioxide, the us would be expected to demonstrate some more moral responsibility towards promoting alternative energy resources. Excessive dependence on fossil fuels is causing atmospheric concentrations of greenhouse gases to rise at a high rate, leading to global warming and climate change. Instead of improving matters, the new George Bush administration, in its new energy policy has announced a cut of 37 per cent in the budget of its renewable energy resources programme.
