Don't we all, but 'facts' (especially on this subject) seem quite conflicting - No matter which side of the argument you wish to present, 15 minutes on Google will get you all the 'facts' you need
Here's an interesting article - http://www.electric-cars-are-for-girls. ... -cars.html
As you can see, "According to the World Resources Institute, electric powered cars recharging from coal-fired plants will reduce CO2 emissions by at least 17 to 22 percent."
Since we use coal to generate about 50% of our electric power here in the USA, those figures should be considerably better than the quoted 17 to 22 percent
Since 'facts' are so hard to come by, I'd opt for a little common sense - Efficiency usually relates pretty well to scale. It makes lots of sense (at least to me) that most any large power producing plant would be more efficient at converting one form of energy to another than any fossil fuel burning car. I've read many times that an ICE powered vehicle only converts 15 to 20 percent of the energy in it's gasoline fuel into motion. Most of it is wasted as heat, not to mention all of the energy it's wasting when sitting still or moving very slowly. Power plants, no matter what form of energy they use, recover and reuse much of that wasted heat. Also, all of the kinetic energy an ICE powered car wastes when slowing and stopping, only to expend all over again when getting back up to speed. This is one reason why hybrid vehicles get better fuel economy than similar all gasoline vehicles . . . . they can recover much of that wasted energy
If you drive an ICE powered car and your 'facts' prove to you that you're generating less carbon than the average EV'er, I'm happy for you - I'm sure it helps you to sleep well at night and that's the important thing
