I've read today something that may be of help.
It's a comparison between Bitcoin consumption and others' (US fridges, US electricity transmission/distribution loses). It can help to show Bitcoin doesn't consume
that much electricity.
The University of Cambridge currently reports that the Bitcoin network currently consumes 94 terawatt hours (TWh) per year. To put this into context, all of the refrigerators in the United States alone consume more than the entire BTC network at 104 TWh per year.
Furthermore, transmission and distribution electricity losses in the U.S. alone are 206 TWh per year, which could power the Bitcoin network 2.2 times over. Cambridge also reports that the Bitcoin network power demand has decreased by 28% since mid-June. This is likely due to miner capitulations during the bear market and more efficient mining hardware being adopted.
