The thing is, the United States is self sufficient in petroleum. But domestic prices will go up to reflect the effect on world supply.

Arguably the same could happen given widespread use of non petroleum sources of energy. Prices will go up to reflect the marginal cost of hydrocarbon based energy, even if that use is minimal, until the point where the energy network is completely decoupled from those markets.

This happened in the United Kingdom after the invasion of Ukraine. More wind was used as gas became more expensive. But the price of electricity from wind also went up.

US could ban fuel exports. Unlikely as rich people would suffer, but they may be placated with bribes.

The UK increase was because of how the contracts work but yeah agreed in general. Sustainable energy is good for a bunch of non environmental reasons.
