How much electricity do Wisconsin's data centers use?

We don’t publish a state total, and the reason matters: roughly four in ten facilities never disclose a capacity, so any sum would look like a census of Wisconsin's data center load while leaving out the sites that stayed quiet. Each facility page shows the figure its own source states. A single large campus can draw as much power as a small city.

Are Wisconsin data centers near protected land?

3 of the tracked facilities in Wisconsin sit within 10 miles of protected public land, measured to the real boundary of the nearest national park, wilderness area, wildlife refuge or conservation area; 0 sit within a single mile.
