Bitcoin mining has never been something that takes away any energy that the world desperately needs. The annual energy loss is as much as 50 000 TWh, and Bitcoin consumes about 220 TWh - all other discussions are superfluous and meaningless. Even if by some miracle it happened that mining stopped today (although it is practically impossible), the question is what would happen to the price if no one mined, which means that no one could process transactions.

Perhaps it would be interesting to ask what would have happened if Satoshi had set the max supply at 19 million BTC and what would be the price of 1 BTC today?
