EVs compare even better to ICEs if you take into account the energy needed to take crude oil from the ground and turn it into gasoline/diesel.

- kragen 2y agoYeah, I didn't try to estimate losses due to the rest of the energy system itself; there are also transmission losses with electrical energy, as well as battery losses. Do you have a ballpark for the sizes of these different losses? I'm assuming that for gasoline it's mostly the energy consumed in hydrocracking?
- adrianN 2y agoThe range is pretty wide depending on the source of the crude oil: https://en.m.wikipedia.org/wiki/Energy_return_on_investment https://en.m.wikipedia.org/wiki/Energy_return_on_investment Refinery losses seem to be around 10% https://anl.app.box.com/s/a8s8qagg9smrl902jh5m6v06oe1ls0r6 https://anl.app.box.com/s/a8s8qagg9smrl902jh5m6v06oe1ls0r6
