Chinese data centers like to use air cooled chillers for cooling, not evaporative coolers. It's simple because power for the chillers is cheaper than water for the evaporative coolers. The opposite is true in the US

Evaporative cooling is a matter of convenience and cost, not a necessity. Other cooling technologies can be used. Intel has already proven a closed-loop system can work just as well.

One of China's big sources of power is hydroelectric such as the Three Gorges Dam, so if you want electricity and water in one place, then there it is.

I wonder if submerged system with coolant could mitigate this ?
