Maybe the energy will be there. But progress in battery technology has been depressingly slow despite huge investments. The economy you describe does not exist without order of magnitude jumps in battery technology.

The tesla car gets 250 miles on a charge. So just doubling that to 500 miles would mean that teslas get more on a charge than most gasoline cars get from a tank of gas.

Doubling is not an order of magnitude. An order of magnitude is 10 times higher.
Depends on your number system choice.
