There was a comment in a sister thread positing that Cryptocurrencies currently use 1/3rd of the entire data center energy use on the planet. I haven't looked into this, and I don't endorse this data or the comment, but it's likely relevant to your question: Bitcoin uses about 1/3 the energy of all datacenters in the world put together. Datacenters use about 205 TWh/year. https://www.networkworld.com/article/3531316/data-center-pow https://www.networkworld.com/article/3531316/data-center-pow... Bitcoin uses about 75 TWh/year. https://digiconomist.net/bitcoin-energy-consumption https://digiconomist.net/bitcoin-energy-consumption And that's with everyone on the planet using normal money every day and just about no one using Bitcoin.
