Greens vs Resources

I'd first seen a mention of the fact that a Hummer uses less energy in its lifecycle than does a Prius on Art de Vany's blog, and now I've run into more details via Going Private. As usual, the environmentalists' arguments depend on emotional outpourings and moral posturing, their actual programs waste resources as any elementary economic analysis will show. (However, I think equity private neglects a factor explaining why manufacturers have built the cars -- government-mandated average mpg standards.)
