Thus, the true cost per mile of electric powered cars needs to include the cost of the coal, loss of heat while the coal is burned, and cost to clean up the coal smoke and ash.

If you are going to do that, you need to add in energy used in exploration, drilling, production, transportation of crude oil, refining, transportation of gasoline, etc.

There should only be one measurement that matters to the end consumer, Miles per dollar.

Right.

Electric cars will probably be the most costly per mile driven.
