My understanding is that power loss through transmission averages at 6-7% for electricity (don't know if the Wikipedia article includes all losses happening: http://en.wikipedia.org/wiki/Electric_power_transmission#Losses http://en.wikipedia.org/wiki/Electric_power_transmission#Los...), which is really not that bad. I am not an engineer, but converting oil to gasoline/diesel, distributing it and burning it at an inefficient RPM in a car might be just as bad or worse.
