I hope that most of the miners now have switched to renewable energy resources so that they would have been able to be more profitable in their investments.
I think the majority of the big farms have done already and the big ones who want to stay alive in this game are forced to do so or otherwise they will have to go offline during the upcoming crypto winter.
I think many people would like to believe so, because they are in fear that bitcoin will be banned because of the impact on the envoirment. But I think the more honest answer is that miners will use the energy that they can get for the cheapest price. So if you can set up your miners next to a solar farm and can get cheap energy it makes sense, but the same goes for mining next to a coal power plant. So I think it all depends on how prices for energy will be in the future.
