It's a response to the FUD that is water usage in data centers. Data centers don't use a meaningful amount of water when compared to just about any other industrial application, or many recreational ones. Data centers used about 66 billion liters 2023. source: https://escholarship.org/uc/item/32d6m0d1 Golf courses used 2 trillion liters in 2020. We won't even bring up almond production.

The issue is though data centers are being built in areas with scarce water resources and they get prioritized. They still use a lot of water.
