Would have been more interested to know how the avg EEV household electricity consumption compares to offset gasoline usage (as energy). My understand is that the efficiency of power plants is so much higher than automobile combustion engines that even if all power plants were gas-powered, EEVs would be an efficiency improvement thermodynamically.

I mean, of course EEV household consume more electricity, and of course they are parked at night...and that happens to be cheap electricity hours.
