Overview
- Robin Gaster lays out five concrete regulatory principles — transparency, watershed review, performance standards, integrated water‑energy review, and standardized metrics — as a framework for managing data center water impacts.
- The commentary cites 2023 estimates that data centers used about 66 billion liters of water directly and roughly 800 billion liters indirectly for electricity but notes those figures come from limited sources and need standard validation.
- It emphasizes that most water impacts stem from the power used to run data centers, so permits should combine assessments of direct cooling needs with the water footprint of marginal electricity generation.
- Federal and grid efforts to speed new power for AI campuses, including DOE land moves and regional grid rule changes, have increased local resistance and spurred moratoria and legal challenges in some communities.
- The piece says improving disclosure, common metrics and joint state utility–water reviews would let suitable projects move quickly, protect stressed watersheds, and reduce the secrecy and conflict that now delay decisions.
