"In this report we investigate the geographical distribution, composition, efficiency, electricity
consumption and electricity sources of the Bitcoin mining network. We also investigate trends in
hashrate, hardware costs, hardware efficiency and marginal creation costs"
...

"we show that bitcoin mining is predominantly powered by renewables, with a lower bound of 78% renewables penetration vs the 18% global avg.
(It's all in the paper. The short take is that we looked at the energy mix in all relevant Bitcoin mining regions, assumed miners use the same amount of renewables as the local market, and weighted the regions by miner density.)"

a jeste:

..."miners are, in significant numbers, leaving China, or choosing not to reinvest within China. Instead, they are setting up operations in certain regions of Scandinavia, Russia, Canada and the United States"

..samozrejme to zase zavisi na nejake chybe jejich vstupu, jsou to vzdycky odhady, protoze podstatou bitcoinu je ze tezit muze kdokoliv odkudkoliv a nemusi to nikomu rikat.. ale rekneme asi zatim nejserioznejsi report co jsem videl
