You’re being down voted, but this was a useful comment for me. Made me realize that there’s plenty of energy being spent to mine and handle other commodities too, e.g. gold.

Gold is generally a one-time investment though - you could smelt it into a bar at a high initial energy cost, but after that, transferring it is free. As opposed to BTC which apparently costs 300 KWh per transaction.

How is it free after the initial smelting to transfer?

Moving physical gold around is very expensive.

Exactly. Plus you need to factor in the exploration, mining, and extraction costs too
