AI Data Centers Face Water Limits
Coverage from EY, NC State, and others
AI-driven data center expansion is increasing scrutiny of water demand from facility cooling and electricity generation, particularly in water-stressed regions.
Evaporative cooling remains a major source of direct consumption, while closed-loop, liquid, air, and recycled-water systems could reduce withdrawals. Incomplete facility-level disclosure and inconsistent accounting are complicating permitting, community review, financial risk assessment, and long-term water planning.
