"The average energy consumption for one single Bitcoin transaction in 2020 was 741 kilowatt-hours."
Just to put this into perspective:
The average value of a Bitcoin transaction is currently $119 and requires energy worth roughly $100 (the world average price is $0.14 per kWh).
The global energy consumption in 2017 was 22.3 terawatt hours.
If we moved all financial transactions over to Bitcoin, we'd require over 1000 terawatt hours... each day(!) for Bitcoin transactions alone(!).
That doesn't even factor in that Bitcoin's energy consumption will be exponential to the amount of transactions.
@fribbledom well that's depressing
