Consider this: in Sichuan and Yunnan, the two most hydro-rich provinces of China, despite the high concentration of miners over there due to cheap electricity, there is such an surplus of electricity that they abandon over a hundred TWh of hydropower every year. This abandoned water is literally run through the dam without spinning the turbines. This is more than the worldwide consumption of electricity of Bitcoin.
This is a result of mostly inadequate grid infrastructure that will take decades to solve.
