Re: apples for apples

If you calculate the amount of energy used by UK road transport today, even if you then halve it because electric cars are more efficient, and add it to the current national grid draw, you get a figure that requires every power station in the country to be running flat out, 24/7/365.
True, but not as bad as it seems. I can't remember the exact figures, but apparently the process of refining oil into petrol requires a considerable amount of electricity - about 1/3??? of the amount of energy in the fuel, and so that would be released back into the grid.
But even so, it would be a massive infrastructure change, and there are almost certainly better alternatives, using renewable leccy to create hydrogen, alcohol or whatever.
