“As a whole, battery vehicles are pretty horrible on efficiency from source energy. Gas is better.”
Then why is the $/mile fuel cost less for electric cars?
Then why is the $/mile fuel cost less for electric cars?Do they factor in the value of the electricity drained from the grid?
If not, aren't they overlooking a significant cost?
It isn't.
Much of the perceived savings is merely cost-shifting, along with a complete failure to add up all the costs. It's still cheaper to fill your gas tank and drive 450 miles than to charge up your car battery and drive that same distance. People don't look at their electric bills. People using public charging stations do not even pay the electric bills.
It is still cheaper to transport 10,000 joules of energy in the form of natural gas or liquid hydrocarbon than by means of electric lines. And the hydrocarbon form is easy to store. Generated electric power cannot be stored very long or in large quantities and losses in transmission lines are considerable. Battery storage (elector-chemical in nature) is already pushing known physical limits. Perhaps there are some new discoveries to be made. That won't be cheap.
