Global warming or not....why would people be against developing alternative energy sources that would create whole new massive industries and employ millions of Americans? Clinging to 20th century industry won't work....that battle has been lost overseas. Time to adapt and reassert yourself as a world leader, or slowly watch the decline you've been seeing since the 80's.
Unless people just want to play partisan politics so they can say "Ah ha! I told you so!! Stupid liberals". Which seems WAY more important that being on the cutting edge.....you know....the place that made America so rich and powerful in the first place.
