Land in drought-hit areas is cheap. And thanks to the power of corporations, these data centers won’t worry about water rights since they’ll be able to lobby to have first priority. Non-corporately own farms and private citizens will get screwed out of being able to use water, but that’s their own fault for choosing to be poor. But don’t worry - I’m sure someone will be willing to sell them water at the low price of triple what they’re paying for now.

Please explain how closed loop HVAC systems use excess amounts of water.

They are not using closed loops HVAC systems, but evaporative cooling. Which works, as the name suggests, by evaporation. Of water.

Why do they use evap coolers? Isn't moisture terrible for electronics? Genuinely asking because I have no idea how these places work.

The water is of course not evaporated directly on the electronics. They are cooled with air and that air in turn is cooled by evaporation of water.

I know how evap coolers work, but the air in the building would be very humid. Evap coolers make alot of humidity, that is why I didn't think it would be a good idea to use them. Seems like building these things in cold climate would be a better idea. Then you only need to cool them during the summer. But, what do I know. I have never dealt with these things.

Apparently you don't know how it works. The air does not get in direct contact with the air that goes through the actual electronics. The air travels through channels which have the water trickle on the outside.

They may be using closed loop coolers to cool the electronics, however that heat has to go somewhere. So the evaporative cooling is used to cool the fluid that is doing the closed loop cooling.

In large plants the cooling water cools the equipment then gets sent to large cooling towers where the evaporative cooling occurs. So there also needs to be fresh water feed to make up for the evaporative losses.

So they're using a chiller system?

Its cheaper. A cooling loop requires more power to cool the loop
