Most new builds don't even use evaporative cooling afaik, this will probably be closed loop. The implications being you're not risking the local water table and overall consumption is lower, a lot lower.
I don't see in that article where you're getting 60-80%. Why link to one example instead of the "LOTS" of reporting that shows the 60-80% number you're claiming?
My goal is to point out to you that it's very easy to self educate on this topic, your next step is to open Google up, or talk to your favorite LLM! I'm merely pointing out that it's trivial to start gathering that information.
This question was posed after trying to "easily" educate myself on this topic and not coming up with anything other than that same article about Microsoft's data center and vague references to data center operators "intending" to use closed-loop cooling. I did not ask the question to others without first trying to research it myself.
Again, I ask, where are you getting the 60-80% number?
