Overview
Resources at Risk
Clean Wisconsin was the first environmental group in the state to call for a pause in all AI data center development in Wisconsin. But there is much more work ahead. We need strong regulations and guardrails to keep our communities safe.
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.
90
Premature deaths could be caused by pollution from one large gas plant built to serve an AI data center.
5,324
Megawatts of dirty fossil fuel power is already being built or proposed in Wisconsin to meet energy demand driven by data centers
27 Billion
Gallons of water a day could be used by power plants serving just three AI data center projects in Wisconsin—the equivalent water use of 1.3 million Wisconsinites.
