Artificial Intelligence's Water Use is Lower Than Commonly Perceived

May 1, 2026

AI Summary

Concerns about the water consumption of artificial intelligence data centers are often exaggerated. Estimates suggest that AI's water use in California accounts for only a small fraction of the state's total water consumption, highlighting the need for more informed discussions around the resource demands of emerging technologies.

The rise of artificial intelligence relies on data centers, which require significant energy and water for cooling.
In California, data centers occupy about 15 million square feet and their water use for cooling is estimated to be between 32,000 to 290,000 acre-feet per year.
This water consumption represents approximately 0.055% to 0.7% of California's total annual human water use, which is around 40 million acre-feet.
AI water use is relatively modest compared to agricultural needs, potentially supplying water for 10,000 to 100,000 acres of irrigated land.
Concerns about data center water use often stem from a lack of transparency and speculative reporting, rather than solid scientific evidence.
The impact of new data centers on water resources is particularly relevant in arid regions facing existing water scarcity, such as proposed developments in Imperial County, California.
