Also, please look at diesel-electric engines.

Same principles applies to the energy costs of an electric vehicle, they just happen to charge their batteries from a source other than onboard motor.

Also, at 12 cents a kilowatt hour, the costs are much less than how much petrol you'd use in an e90 over the same amount of miles. I think your math is off. As one reviewer stated, his 300 mile trip cost about 7 bucks. That same trip in an e90 will cost about 60.
