Residents cheer as Tucson rejects data center campus

I think in this case, solar energy is the best way to run the cooling systems, even if it requires an absurd amount of power to exercise compressors, etc. in order to improve heat concentration and rejection efficiency. As long as it's all green and theres a disaster recovery plan, who cares?
Meanwhile in a cold climate you can do cooling by just blowing outside air through a filter, so the alternative in those climates is that rather than running a compressor.
Another dumb question: why are we building projects that need tons of power and water in the Sonoran desert instead of next to the Great Lakes
You pump water up from the local water table to run your evaporative cooler. The water evaporates. But the air was at 10-20% humidity. The water from the evaporative cooler will raise the humidity, a little bit, but not enough to make it rain. It may make it more likely to rain somewhere downwind a few miles, or a few hundred, but not here.
For your second dumb question: At least some of the Great Lakes have at times had issues with water level. (They want enough to allow ships to pass between the lakes.) The upside is, there the humidity is high enough that you're more likely to get the water back in the form of increased precipitation.
This is objectively false, particularly when we consider that much of that food and water are exported. It’s also irrelevant in Tucson, which doesn’t have Central Valley syndrome.
Which is also paid for data centre access.
We need food production as a matter of survival. That doesn’t mean all food production is inherently more valuable than everything else. We let most food spoil without being eaten because it’s more efficient to do that than treat every calorie as precious.
> just like the absurd overvaluation of all things AI doesn't change the value proposition there either
Literally does.
There are good arguments against a data centre in Tucson. “We could grow food with that water” isn’t one of them.
They won't be as high of altitude though so their shots won't go as far. Too bad.
It's worst. They use tap water.

What was once a rural county outside of Fairfax, Loudon has seen tremendous development thanks to data center expansion. Now Prince William County( one county over, westward) is trying to fight the same battle before it gets too big of a problem for them.
However, I’m puzzled by this portion of your comment: ‘…has seen tremendous development thanks to data center expansion.’
The major residential growth in Ashburn, Broadlands, Sterling, Lansdowne, and surrounding areas significantly predates the data center boom. These communities were already experiencing rapid expansion and large influxes of new residents well before the data center industry took off here.
