Do you have any data on the renewable energy claim? Considering that mining goes on 24/7, I would find that highly dubious (even if true, "most" could mean 51%, or 90%; 10% of the annual usage of Argentina is still a non-trivial carbon footprint). It would matter far less if the externality of carbon were taxed properly [0], but I think it's appropriate to be horrified at PoW when other low-energy mechanisms exist (PoS, memory/storage-based). The fact that existing financial infrastructure is also inefficient and untaxed is no excuse to double-down on passing ecological debt to our grandchildren (at a usurious interest rate).
