He said it wrong, but isn't it implied that he meant the right thing? What's the correct term or principle? The one where we get 30-40% of the energy from fossil fuel in ICEs whereas an electric motor gets some 96% from the battery?
Yes, disclaimer here, disclaimer there, electricity has to be produced in order to be put into a battery. But didn't he mean the right thing?
ICE is closer to 20% gas to wheels. 30+ (reaching 50 on large diesel) is at the best efficient point, mainly when used for diesel-electric or pumps.
EV has 85% charging and 85% battery to wheels, overall 70+.
That's "energy efficiency," not "energy density."
