Anyways my main point was that a lot of things people do for fun are more or less directly bad for the environment, like for example creating dozens of silly images with stable diffusion. But it's still better than crypto mining imo, as doing "fun things" usually benefits you/your mental health.
Fermi estimate: 10 million latest Xboxes, used for 1 hour per day.
Power estimates seem to vary from 120 W to 315 W, let's say 200 W including display. That's 2 GWh/day. Probably similar for Playstation, or at least close enough for a Fermi estimate. I'm going to guess similar for PC gaming also.
Smartphones are what, about 1 W? But a few billion of them? 1 hour per day makes that another GWh/day?
So probably about 7 GWh/day for Xbox + Playstation + PC + mobile, 2.5 TWh/year.
Bitcoin is estimated to use 131 TWh/year according to Wikipedia.
Yeah, you're right, it's not even close.
Gaming is not an activity that produces something, likewise any form of entertainment for that matter. So in the sense that nothing comes from the electricity and time used, gaming is an "anti-environmental" activity.
I personally don't agree with any of this notion, because life is worthless if we can't accept life is pointless, but if we are striving for a world where consumption must always produce something then gaming is one of many things that must be eliminated.
