There is a considerable amount of electricity required to refine gasoline, models as to exactly how much vary, but a figure of 8KWh/gallon of gasoline is credible. Which means that a gasoline-powered car needs more electricity to drive 100 miles than an EV does!
This suggests that if all the electricity used to refine fuel was simply used to charge vehicles instead, there would be sufficient generation capacity (on a global basis) to power electric cars and that all emissions directly from cars would in effect be eliminated.
