That's not a problem at all. If you compare the raw power usage, it's still both cleaner and more efficient to use electricity than gas. Also, gas engines aren't going to get that much cleaner, whereas the energy grid is only going to get cleaner with cleaner coal, nuclear, and renewables. I wouldn't be surprised if in 15 years from now, if half of all new cars sold use electricity as their primary source. Energy independence should be a goal for every country, but especially for a country like the U.S. that uses so much oil.
