If you've been assuming you need to replace all the oil with the same amount of electrical power then you're seriously wrong.

Electric motors are extremely efficient over a wide speed range, whereas combustion engines aren't very efficient even in their relatively narrow optimal range and the arrangement needed to translate that power into motion further reduces overall efficiency.

While replacing the energy 1:1 would entail roughly doubling US electrical generation you actually want to replace the function and that's maybe 20-25% increase. It's not a trifle but it's very do-able. Especially if you time-shift car charging so that it's happening when humans are asleep and there's slack in the network.

You charge your phone while you sleep right? If you're used to filling up a car at a gas station it can feel weird but you can charge a car while you sleep too.

Its not a 1:1 replacement but its also quite a significant amount of energy and infrastructure that is needed. You still have losses in electrical production from Gas/Solar/Wind/Nuclear to your charging round trip efficiency.

Its a massive change in how things operate in the US - significant amount of money reinvested into the grid and not solvable only through behavioral change. Thats one of a quiver of things that need to be done.
