It depends on the company. Some of these data centers are frankly ran by assholes, which draw a lot of power and water.

It is because they are narcissistic idiots.

Our centers use solar and we actually give to the grid, we use grey water (meaning we reuse water by cooling it) and dielectric oil systems.

But there are fuckfaces using gas generators. So there is a bit of a spread. Like, we have bee hives. We just thought things out differently.
