AI Data Centers Strain Global Freshwater Supplies
8.0
A new study reported Dec. 18, 2025, finds that AI data centers increasingly strain freshwater supplies, with about 45% located in river basins facing high water risk and US facilities consuming roughly 66 billion liters in 2023. Researchers say server cooling and electricity generation drive the footprint and call for mandatory water-disclosure rules and water-efficient cooling to reduce local conflict and guide sustainable siting.
Key Points
- 1Identify concentration: Around 45% of data centers are in high water-risk river basins globally.
- 2Highlight impact: US data centers used about 66 billion liters in 2023, stressing local supplies and ecosystems.
- 3Recommend actions: Mandatory water disclosure and efficient cooling can reduce conflict and enable sustainable siting.
Scoring Rationale
Highlights significant industry-wide water risk and clear mitigation steps, but relies on a single study and limited disclosure.
