My household's total electricity consumption for 2021 was ~1,200 kWh. Looking at the value (light, cooking, ...) I got from that (and the price I payed for it), it's insane that a single Bitcoin transaction would've used the same amount of energy. Stop Bitcoin & Co!
In 2021 the Bitcoin network handled ~97 million transactions. This equals roughly 0.012% of the worldwide volume of non-cash transactions.
Bitcoin was responsible for 0.54% of global electricity consumption. On average, that's 1,386 kWh per Bitcoin transaction.
