That isn't the whole story. At least some of these new datacenters are gigawatt class. That's multiple sq km of solar.

Water usage is also an issue. A continuous 1 gigawatt is enough to boil off 1.3 million liters per hour which over 24 hours equates to very roughly 90k residential users. If it isn't boiled but is instead returned lukewarm it will require many times that amount due to how large the heat of vaporization is. Compare to the entire state of Florida at "only" 23.5 million people.

What? The water is not getting boiled off. Datacenters, for the most part, have closed liquid loop cooling systems. Electricity goes in, hot air and bits come out.

did you move the goal post, or erect a new one? either way- residential use is penny ante in terms of water usage. So much so that comparing data center use to residential use without including industrial, commercial, and irrigation can only be in bad faith.

Particularly since usage reports typically present all the numbers in the same chart or grid.
