Yea, I wrote about this recently:

Ethanol is not a green fuel by any means and is a boondoggle on top of that. We can't produce enough of it to remotely satisfy our needs.
If dumb people weren't involved in decision making, we would have an energy system something like this:
Nuclear power plants providing electricity. Plug-in Hybrids that go 20 miles on an electric charge before needing to use gas.
Both technologies exist, are relatively cheap in mass production, and would drastically reduce our dependence on foreign oil.
But we won't get them any time soon because the same people who cry about global warming are the same idiots who cry about Nuclear power. It's one of the reason the global warming crowd has so little credibility with a lot of people because we already know that the enviro-left's grasp on science is tenuous at best.
