If data center water use is such a concern, why not require that data centers invest in closed-loop cooling systems? By closed-loop, I'm talking about re-condensing evaporated water and allowing the water to cool. Cooling the water would be more expensive in hotter environments, but still achievable. These data centers seem to have wild amounts of money for investment, why not just mandate conservation requirements?

This IS the complaint.

Data center water use is in fact not a valid concern.

Condensing/cooling the water takes even more electricity though. So you're trading water savings for increased energy use. Maybe OK if it's all renewable, but in most areas it's not.

imo this is a pricing problem more than a cooling-design problem. datacenters get cheap clean water while locals pay for the pipes and grid upgrades.

Regulating AI? America would never!

The tradeoff is power vs water. Water is currently cheaper.
