U of M Morris, known for sustainability, takes on renewable heat

One of the state's greenest university campuses is getting even greener. The University of Minnesota Morris reached carbon neutrality when it comes to the electricity that powers its campus, thanks to two wind turbines named Bert and Ernie. Now, it's taking steps to decarbonize the source of heat in its buildings. That's led Morris to a new thermal battery that it began piloting in March. It is believed to be the first campus in the U.S. to use this technology for heating. UMN Morris Sustainability Director Troy Goodnough joined MPR News host Nina Moini to talk about how it works.
