*As Stevens explains, Bitcoin mining accounts for only about 1% of global energy expenditure on heating. As he puts it: "If 1% of comfort heating were converted to hashrate heating at the current estimated average mining chip efficiency of 25 J/TH, we'd add over 1 ZH/s to the network, effectively doubling its computational size." Or put more simply, if only 1% of the electricity used on generating heat around us went to Bitcoin mining, the amount of computing power dedicated to securing Bitcoin would double*
