High energy prices drive investment in cheaper alternatives, which would be renewables. That's a good side effect because we need more of that. Though of course it sucks for people who don't have the opportunity to make the switch yet. And while it is short term nice for coal and gas suppliers to be able to sell at a higher price, the price instability is going to decimate their customers and accelerate the move to cleaner and more price stable sources of energy.

People working in coal mines need to actively worry about layoffs. Many remaining coal plants might not make it through the decade and a lot of mines have already closed.
