For half the US population (those in regions that use more renewable power sources), electric vehicles are equivalent to about 70mpg in terms of emissions, so they're a clear win. In the regions that use mostly coal, it's more like 35mpg, so a really efficient gasoline-powered car is a better choice.[1] However, I'd argue that even a car that gets 35mpg is better than average and its use should be encouraged.
