PoW is an environmental disaster because of its terrible incentives. When the price is low the amount of energy spent isn't such a big deal because it will be limited by the expected reward (which is low), but the more the price raise the more miners will spend to get their rewards (which correlates directly with a higher energy footprints).

And next time you think a "grey goo" or "paperclip optimizer" scenario can never happen, think of this. A clear cut case of it, we're just lucky humans were still involved so we can choose to pull the plug.

A distributed plug though, that will be hell to unplug it!
