Does anyone really believe that the bulk of Bitcoin mining energy is coming from renewable energy sources that would otherwise go to waste?<p>Obviously some of it might come from such energy sources, but the idea that Bitcoin is somehow mostly powered by green, renewable energy that would otherwise go to waste is a massive exaggeration. I know Bitcoiners want to believe that Bitcoin has no harmful energy impact, but we need to be honest about how a system that incentivizes increasing energy consumption is <i>not</i> a sustainable solution.
