The water use thing has been overblown. The energy use is a different matter. The thing is that a lot of these data centers want to have their energy use behind the meter. But it's going to take permitting reform by Congress to get it done. And the issue with that is neither party wants to do something where if they do it, the other side comes out of it looking good as well. So everyone loses with higher utility bills. Yay Congress.
Can you expand on the water usage concern being overblown? I'm asking sincerely. Because that's the number one issue I see raised with these things. Especially in areas where water scarcity is already a concern.
Closed loop chilled water cooling systems consume very little water, however they do consume a lot of energy.

Closed loop systems use water cooled centrifugal chillers which use forced draft cooling towers which use a ton of water. Not many data centers are using air cooled chillers (which use way more energy overall than water cooled centrifugals).
I was at the Trane plant last summer and they were filling orders for 20+ 2,500 Ton machines for a single customer. They aren't using close loop hot side cooling systems for those chillers.
