Interesting calculation! But the point of shifting electricity usage from refineries to car batteries still stands: Apparently it's 1.5 kwh per liter of gasoline [Edit: this might not be accurate, or might be mainly related to drilling, see comments below]. At 7-8 liters/100km we've already covered 11 kwh.
Edit: And 7-8 liters/100km for a Tesla seems optimistically low. But maybe 18kwh is also optimistic.
- twic 5y agoI think you should cite a source for that 1.5 kWh/litre number. It seems there are a lot of varying claims here [0]. Looking at the US statistics for 2019, it seems refineries used 47 140 million kWh of electricity [1], and produced 3 199 032 thousand barrels of Finished Motor Gasoline [2], plus a lot of other products. That makes 0.093 kWh per litre, for the package of a litre of gasoline plus a bundle of other products. If gasoline is half of the output of refineries, then the rate is more like 0.05 kWh per litre. This is just for refining, and doesn't include the energy cost of drilling, transport, etc. But 0.05 is a long way from 1.5.

- chki 5y agoYes you are correct, that's an important thing to look at. Apparently the main energy usage which causes the 1.5kwh number is drilling, I'll see whether I can find some sources. If it's actually drilling that makes a big difference because drilling might not be done where the oil is raffined
