> maybe don't make a campaign promise to end fossil fuels and act all surprised when the prices for fossil fuels go through the roof

There's a well sourced explanation in this video regarding the price of fuel that I really enjoyed. https://youtu.be/QnBqAzJXVGo There's also previous ones dealing with oil drilling.

The tldr idea is that the US could drill more to satisfy the supply right now, but oil corps like money and high oil prices give them that. And that's regardless of the demand going down over years - the drilling rights are already in place.
