Yet unrealistic extremists from the left would have us give up cars for bikes, etc, it's just not going to happen. How about we stay with reality, we're not going back to horse and buggy. People are not going to be willing to pay 3x more $ for solar or wind power. They block windfarms because a few stupid birds might die or it might block the view from Martha's Vineyard. They block nuke power and domestic drilling despite environmental advances in all industries. One of my favorites was the ELF ones that burned the Hummers at teh dealership...causing more pollution that the Hummers would have in 10 lifetimes. I'm for energy independence but I'm not willing to go broke to get it. Fortunately, one short term possibility is biodiesel but even that has "issues."
