Claims
- Amazon's global data centers withdrew approximately 2.5 billion gallons of water in 2025, a small fraction of the 117 trillion gallons withdrawn in the US alone in 2015.
- Google withdrew over 6.1 billion gallons in 2024; Microsoft withdrew approximately 2.75 billion gallons; Meta withdrew approximately 1.4 billion gallons in the same year.
- Aggregate AI data center water consumption is negligible compared to US agriculture, lawn care, and golf courses at the national scale.
- Individual data centers can still meaningfully strain local water supplies even when aggregate national figures appear small.
