I agree.
My point was to determine what the true energy cost is per mile for electrical versus crude oil derived fueled cars.
The common “green” assumption is that electrical cars “saves” fossil fuels, (coal, nat. gas, crude oil), when the reality is that 40 % of our electricity is generated from the burning of the fossil fuel coal, and its derivative coke.
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.
A better measure of cost per mile might be the to convert the energy consumed to a standard, such as the old BTU, and then use that to compare the expenditure of BTUs per mile for the various types of power consumed by vehicles.
Depleteable fuel sources, (such as Nuclear, Coal, Natural Gas, Crude Oil), are being depleted to provide electric power to “green” energy electric cars, but the cost, and loss of these valuable resources is not realistically included.
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.
