I think more important than global warming, and more of a reason to switch to renewables, is the fact that oil is running out, and if oil ran out like today, we would not be prepared for it at all. Therefore we should be as prepared as possible.
There wasa great program the BBC did called Burn Up, which effectively was about how the Saudis had lied about how much oil there was left, and many people (mostly American :P) wanted to cover it up for fear of the economy, though eventually the Oil company CEO that found it, released it to the press.
As far as I'm concerned that's a much better reason, and one that isn't open to debate, after all it's not as if oil is infinite lol.
