This is not the correct comparison to make!

Both future car designs, in the correct comparison, will be electric -- and will have identical drive trains . . .

Ah, yes. I see your point. I was comparing apples to oranges, and the correct comparison is Stayman Winesap apples to McIntosh apples.

On a National average this is what? 35% in the USA ? This is not a large fraction.

That's a little complicated. For all electricity, hydro plus nukes plus other renewables is 27.9%. See:

However for electricity at night in some geographic locations the numbers are quite different. At night they only leave on baseline generators which are mainly nuclear. In Texas a substantial fraction of electricity comes from wind and you cannot turn it off at night.
