"I will have to go over them when I am wide awake, but it sounds like one of the mistakes that get made when converting units incorrectly..."

Yes, I'm getting the sense we're comparing apples to oranges or even lima beans. An automobile engine, as I understand it, generates a certain amount of horsepower in order to move on down the road. To do this it "burns" a certain quantity of gasoline. The more horsepower you call for, the more fuel it consumes, and we talk about miles traveled per gallon consumed. An electric motor does essentially the same thing, except it calls for fuel in the form of electrical current. I need to understand the proper unit of measuring its "fuel" usage per mile - KW? Amp Hours? Joules? And then I think I need to understand how to compare its energy consumption to that of an "equivalent" gasoline motor.

Or, I need to forget the whole thing and pump up the tires on my bicycle...
