Question: If we put up all these wind turbines and associated transmission lines, convert the entire American fleet to electric vehicles, replace all of our gas stations with charging stations, and then find out not only that it doesn't work, but that the weather doesn't get any better, will this guy give us a full refund?

"If you have a person who is driving a nice, newer car, having them switch to an electric car, there isn't going to be much benefit in reducing smog," said Tom Cahill, a professor emeritus of physics at University of California Davis. "But there could be a whole lot of gain in climate change."
Because all-electric vehicles like the Nissan Leaf burn no fossil fuels, and plug-in hybrids like the Chevy Volt burn only small amounts of gasoline, tailpipe emissions from electric cars are basically zero.
... In California, because it has for 50 years had the toughest tailpipe standards in the nation, a 2010 gasoline-burning car puts out only 2 percent or less of the pollution spewed by a 1980s model.

In a recent study, Jacobsen computed the carbon footprint of every major energy source, wondering which would be greenest if America converted all its vehicles to run on each. He found that electric vehicles powered by wind energy were best, with a 99 percent reduction in carbon and air pollution emissions from the current vehicle fleet. In fact, every vehicle in America could run on the electricity provided by 144,000 5-megawatt wind turbines, he concluded.
