I’m also a sw engineer so we’re both guessing 😅

I’m guessing those dates centers use that water for cooling whereas most home computers run an electric fan. And furthermore they probably use less electricity per token as they want to maximize profits. I don’t have any numbers to back my hunch up but I’m pretty sure the environment would suffer more if everyone is running their own.

I probably missed a lot of factors such as what type of energy the centers run contra what average Joe runs etc.
