Overview
Resources at Risk
Wisconsin is becoming a hotspot for hyperscale data centers. These massive server campuses are the physical footprint of artificial intelligence (AI). Drawn to Wisconsin for our open land and abundant freshwater, tech companies are working with the state’s energy utilities to push new, massive data centers at an alarming rate. And the harms to Wisconsin’s resources could be profound.
1.1 Million
Wisconsin homes could be powered for the same amount of electricity consumed by a single, 1-gigawatt AI data center
70%
Of all water withdrawals in Wisconsin are for power generation
1,200
Megawatts of dirty fossil fuel power is already being built in southeastern Wisconsin to meet increased energy demand driven by one data center project.
54 Million
Gallons of water a day could be used by powerplants serving just two approved AI data center projects—more water than every home, business and manufacturer in the City of Green Bay.

The Nuclear Option
There is a lot of new excitement around nuclear energy these days, and no coincidence, it comes as we face staggering energy demands from AI data centers. Now, the Trump Administration is relaxing environmental and safety regulations for new nuclear reactors. In this episode, a look at what would happen to our environment – and our energy bills – if utilities race to meet AI demand by building more nuclear reactors.

Offsite Water Use of Data Centers
Data centers require a lot of energy. If they use non-renewable sources, their indirect water use could rival that of entire Wisconsin cities.
Wisconsin AI Data Center Power Needs Analysis and Comparison
1 gigawatt (GW) of data center demand equals the power needs of more than a million Wisconsin homes.
