This study is using water "withdrawal" figures rather than consumptive use. Hydroelectric plants withdraw tons of water, but it goes right back into the river it came from.

Edit - good information on this here: https://news.bgov.com/environment-and-energy/data-centers-us...

The "Consumptive Use vs. Withdrawals" section discusses the trouble with using withdrawal as a meaningful data point.
