I saw an article that mentioned that the total electricity being used for the Bitcoin network was over half of what the Large hadron collider uses. I found this a bit shocking, I had no idea it was this much.
Well, I mean consider how much electricity it takes to power the banks of the world, the ACH system, and all the computer infrastructure supporting them and the fiat-denominated securities markets, and I'm sure you'd have a sum possibly orders of magnitude greater.
