You pointed out France as a place superior to the U.S. in emissions control. I then pointed out that was due to France using nuclear power for most of their electricity production. You then went off about nuclear being bad. You want it both ways, to be able to criticize the U.S. by saying that other countries do it better, then criticize other countries on how they do it better. Make your mind up. As far as efficiency goes, the market determines that. Companies trying to make a profit try to run as efficiently as possible. Governments don't. People often don't. So it appears you'll have to depend on corporations to save the planet. Oh the irony....
