It doesn't matter how much energy something uses. What matters is how energy generation companies generate electricity. Electric cars and banning mining doesn't affect energy generation. Companies don't sell electricity, they sell a commodity (that happens to be electricity) like McDonald's selling hamburgers. It is done for profit so the question is do the customers pay, yes or no. If a Bitcoin miner or a trans health center or aids clinic pays their electric bill, that is the only relevant consideration.
