I don't trust any politicians, for or against global warming, but this I do know, the glaciers are melting and we all rely too much on oil as our primary source of energy. What is the downside to developing alternative sources of energy? It creates high tech jobs and hopefully will eventually lead to energy independence. I'm tired of sending my money to terroists sponsoring regimes in the middle east. I would rather pay twice as much for some other form of energy than send them more money.

And sooner or later, oil will run out. Maybe not in our life time, but someday it will, so why not develop a "replacement" now? Who does that hurt? New technology won't happen by itself.
