Wind is part of the answer. Scientific American published an article last winter called "A Solar Grand Plan": http://www.sciam.com/article.cfm?id=a-solar-grand-plan
It seems like he's ignoring electric cars. We can run vehicles on any natural resource if we convert it to electricity first. And we already have a distribution system for electricity.
The problem with electric cars is finding an efficient, clean, and sustainable way to store energy while the car is resting and then give it back quickly when it needs to run. Hydrogen is often proposed, but the economics aren't there. It's not a fuel in the economic sense; you have to make it. And if you have a clean enough source of energy to make hydrogen, you might as well use that directly for other purposes. And fuel cells pose a big, big lifecycle problem: it hasn't been demonstrated that all those Prius fuel cells are better for the environment when you junk it than an ordinary, cheaper Corolla.
The industry never acted unless it was certian that it MUST act or else things will go to complete shit. Nice to know these idiots are finally putting forth some effort to do it.
