Compare Bitcoin's energy consumption to a country like China. It's not so devastating to the planet. Bitcoin currently consumes around 110 TWh per year — 0.55% of global electricity production, or roughly equivalent to the annual energy draw of small countries like Malaysia or Sweden. China as of 2019 was ~39,000 TWh, with the China ban the energy consumption can only improve. As miners move away from coal and on to more renewable sources and countries.
