UW-Madison is working toward a future where energy systems are cleaner, more resilient, and rooted in collaboration. District Geothermal Exchange (GHX) is a powerful example—offering a sustainable way to heat and cool buildings while reducing carbon emissions and cutting energy costs.

Join Dr. James Tinjum, Associate Professor in the College of Engineering, as he explores how GHX systems work, why they matter, and how they’re already making an impact here in Wisconsin and beyond.
