alt Hacker NewsMost people who believe that data centers use a lot of water aren't mislead about how much water data centers use, but they are unaware of how much water everything else uses. In the great scheme of things data centers simply do not evaporate that much water. They are too small and too few. As a comparative example, all the data centers in Arizona combined use less than 1/50th of the water evaporated by Arizona's own thermal power stations. Or, to choose another benchmark, the evapotranspiration of the rice crop in California is more than 250x the water used by data centers in California.
I think also to a degree, even if someone knows those other water use figures, it's easy to see an intrinsic value to the community from those sources. Many people do not see much value in pushing AI to such a degree where all this new compute is required, and others see a negative impact from this activity. It's much easier to argue against something you feel is wrong or bad than something that is arguably crucial for day-to-day life like electricity and staple crops.
