George W. Bush as made a nice U-turn regarding renewable energy lately. Peole have been talking about reducing America's dependency on oil for years now, but GWB was thought to be an ally of the oil companies and didn't do anything to encourage Americans to move to alternative fuels, until very recently. What made him change his attitude? The ongoing war in Iraq? The situation with Iran? Why now? Is there more to it than meets the eye? Was he simply, as unlikely as it may sound, acting sensibly?
