Gasoline automobiles are incredibly inefficient. If they were converted to electricity, the total energy consumed would be only a small fraction of electric power generated. Especially if most are recharged during off-peak hours there is plenty of spare capacity to handle them. This would consume more fuel, of course. To be more specific, transportation now consumes about 27 quads, whereas only 12 quads of electricity are delivered. That sounds bad! But it isn't so bad because: With electric cars, transportation would only consume ~9 quads AND Nearly all 12 quads of electric energy are delivered during the day, between 10 a.m. and 7 p.m. So you could easily deliver another 9 quads between 8 at night and 8 the next morning. You just have to burn more coal, gas, or fission more uranium. Or build a bunch of wind turbines and use smart metering. See: http://www.lenr-canr.org/acrobat/NRELenergyover.pdf - Jed
