Thanks for the link Eniac, that was interesting reading. The conclusion seemed to be that inefficiencies in refining resulted in 7.5kWh of energy being lost but the actual electricity used was less than 1kWh.
I don't know what method they use to calculate the energy of the crude going into the refinery, it would be an interesting number to know how much electricity you could generate if you ran an electrical generation plant with crude as the input.
And thanks Adrian for that link, those tables are informative. The tables base their electricity numbers on California's mix of fuel sources for generation, are those not better than the national average wrt coal?
Another aspect of the question that perhaps someone has some data for is whether the mix differs significantly for peak and off-peak generation. If the amount of fossil fuel generated electricity is significantly lower non-peak then the numbers might be even better when recharging overnight.
