Reply to comment by TomSwirly in Ethereum’s energy switch saves as much electricity as entire Ireland uses | The success of The Merge concept may now serve as a roadmap to enable a switch from Proof of Work to Proof of Stake in Bitcoin. by chrisdh79

For Ethereum's energy usage, there's a peer-reviewed [paper](https://www.cell.com/patterns/fulltext/S2666-3899(22)00265-3) linked right from the article OP posted. It puts Ethereum's worst-case power demand at 675 kW, and best-case only 36 kW.

I haven't been able to track down how much Reddit's datacenter uses, but I'm guessing it's more than that. Reddit is one of the world's largest sites, and some large datacenters use more than 100 MW.
