What do you get when you mix Al Gore, global warming, whacky environmentalists, skyrocketing oil prices, lots of venture funding, and irrational exuberance? An alternative-energy bubble.

What, you don’t believe that there’s an alternative-energy bubble? Then you’re just not paying attention. It may not be the biggest bubble in the history of technology–yet. And it may not be ready to burst–yet. But it’s a bubble, all right. All the signs are there.
