Core Event: Water Demands of Emerging AI Data Centers
Hyperscale AI data centers—facilities at least five times larger than traditional sites—are being proposed across Wisconsin to meet AI and cryptocurrency demand. Their cooling and power needs consume volumes of water, prompting a poll in which 70 % of respondents said the costs outweigh the benefits, citing water impacts as the primary concern.
Data & Statistics
In 2023 U.S. data centers used 17 billion gallons of water directly for cooling and 211 billion gallons indirectly for electricity, the latter comprising the bulk of total water use.
Key Figures & Groups
- Tressie Kamp, assistant director of the Center for Water Policy at the University of Wisconsin-Milwaukee, leads research on data-center water impacts.
- Great Lakes Compact, the eight-state agreement governing water withdrawals, currently lacks detailed data on data-center consumption.
Official Statements & Responses
Kamp’s model proposes five goals: improve planning; require transparent water and energy disclosure; protect ratepayers from higher utility bills; set efficiency standards for permits or tax breaks; and increase funding for water management.
Criticism & Opposition
The poll also revealed anxiety over utility-rate hikes, and while lawmakers tout tax incentives, critics warn that without safeguards communities could bear hidden costs for modest job gains.
Conflicting Reports & Gaps
Researchers note a lack of transparency because many facilities treat design and operational data as trade secrets, and the Great Lakes Compact’s reporting does not capture indirect water use for electricity, leaving a data gap for regulators.
Verbatim Quotes
- “These large-scale facilities have the potential — if we don’t all act quickly and oversee water impacts, energy impacts — to put an unchecked strain on shared natural resources, even for water-abundant areas like the Great Lakes,” — Tressie Kamp, Center for Water Policy
- “because that water is either evaporated during the cooling of those hot, thirsty data centers, or in generating electricity for that facility, which we just discussed is the bigger part of that pie.” — Tressie Kamp
- “The indirect number …” — Tressie Kamp
- “We need more examples of communities entering into community benefit agreements with members of the data center industry and seeing the general public protected from rate increases, for example, before we can say that a productive and positive relationship can exist.” — Tressie Kamp
What’s Next: Community Benefit Agreements and Policy Review
Stakeholders are urging the adoption of community-benefit agreements that tie tax incentives to safeguards against rate hikes and water-use impacts. The Center for Water Policy’s model is slated for review by state and local officials, and future data-center proposals will likely be judged against the five-goal framework as Wisconsin seeks to balance economic development with water-resource stewardship.
