Although #hash rate is climbing, mainly due to vast improvements in #ASIC efficiency. #Bitcoin's direct power consumption #emissions (dark green line) are starting to plateau due to improvements in overall #Grid carbon intensity & market saturation.

​ The dotted blue line is MT CO₂ minus mitigation such as mining with #Methane + Home/ Business heating, mining curtailment/ demand response schemes taking advantage of cheap clean but intermittent #renewables. Other mitigating factors are #banking sector curtailment (red line) which may already make Bitcoins emissions net negative !

The large drop in emissions during 2021 is due to the China mining ban followed by the subsequent move of much of the hash rate to the US where grid carbon intensity is generally lower. Halving events may cull some of the less efficient mining operations causing a brief dip in power consumption. All calculations are Bitcoin BTC ONLY.
