alt Hacker NewsDoesn't show the comparative energy waste of bitcoin?
This source[0] says
> One Bitcoin now requires 854,400 kilowatt-hours of electricity to produce. For comparison, the average U.S. home consumes about 10,500 kWh per year, according to the U.S. Energy Information Administration, April 2025, meaning that mining a single Bitcoin in 2026 uses as much electricity as 81.37 years of residential energy use.
About 1,200 kWh per transaction, currently[0]. I wrote about this back in 2022, when it was about 2,200 kWh per transaction[1].
Edit: made a chart with this data, but adding in a bitcoin transaction[2]
