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.

The focus of this episode is a large, on-site solar carport installation that recently came online on MSU’s campus. At the time it came online, this was the largest carport solar installation in the United States.  As background, Wolfgang shares the rich history of the MSU energy system dating back to the 19th century. We discuss the role of MSU’s Energy Transition Plan as a catalyst for this project. This plan lays out aggressive goals for the use of renewable energy and the reduction of GHG emissions.  We talk through the decision-making process that led up to this project and end by discussing possible next steps in MSU’s energy transition.
