Carleton College has been getting into hot water — but in the best way possible.

Listen to this episode to hear Martha Larson, Carleton’s manager of campus energy and sustainability, discuss the college’s process for replacing its 20th century steam system with a geothermal-based district energy system. The new system will allow the campus to use heat pumps and the earth’s consistent 50 degree Fahrenheit temperature to help regulate heating and cooling on campus more efficiently. Larson dives into the physics that make the system work, the planning and approval process for the project, and how the new system will help Carleton meet its future sustainability goals in a discussion with host Dave Karlsgodt.
