It was both a steam and jet engine. It was not particularly great one of either, but it was both.
You like to point out that sometimes people use gasoline to generate the electricity for an EV. Here is the question, can people use electricity to generate gasoline for an ICE? Of course not. If you have an ICE, you are tied to one source of power: gasoline. Electricity means you can use any source of power, because they are all used to generate power.
I have high hopes for nuclear power, coupled with solar/wind, and some sort of storage. Nuclear tends to give very steady power(when demand goes up and down). Solar and wind give very variable power, but not variable in sync with demand. I think it could all be made to work well.
We definitely need to rebuild our grid. Even if we were not to convert to a smart grid, our grid is so old it needs a complete rebuild. With the smart grid, with many sources moving electricity all over the place, we can have a new grid, and a more reliable grid.
Or we can just keep trying to use to same old, tired, not working solutions.
