> Crypto-mining apologists will point to figures that say "crypto-mining uses mostly renewable energy". Which is a shit take anyway because that means that non-renewable energy (plus the renewable energy non-consumed by the miners) is now more expensive for everyone else, it's the basic law of supply and demand. And in the process those miners are also making non-renewable energy a more desirable investment because i…
Energy is not fungible. Just because you have electricity in place A doesn't mean you can get it to place B in a cost-effective way, so mining next to, say, a hydro station with spare capacity (where electricity is cheap) doesn't necessarily have any impact at all elsewhere.
If crypto-miners jump in to soak up that excess capacity, that cycle doesn't happen and there's very little positive outcome to show compared to all of those uses. 50 years from now, people are going to wish electrifying normal life had happened quickly but they're not going to be using a blockchain or glad that some speculators were able to make large returns for a few years.
