I'm not going to get into the global warming debate, since BOTH sides tend to take a religious view of it. {our mailing list split over censoring of someone's GW posts, among others.} But, assuming that GW is a problem, regulation is NOT the way to solve it. In fact, regulation in favor of and subsidies to the oil industry is the reason we have oil based fuels and virtually nothing else. The first thing to do is end all subsidies and sweetheart deals to the oil industry, then alternative fuels would have a more level playing field. And I don't have to accept global warming to be in favor of that. I only need to see us fighting over oil in the middle east to see that.

See my post on the subject here.
