On Friday, May 21, Carleton College’s last full-time steam plant operator will “blow off steam” for the very last time. This date marks a significant milestone for the College as it completes a five-year transition to campus-wide hot water heating and a geothermal heat pump system. Since 2008, the campus has reduced its carbon footprint by more than 50%, making significant progress on its pledge to be carbon neutral by 2050.
“I’m excited and proud of how our bold conversion to low-temp hot water energy generation on campus is considerably reducing Carleton’s carbon footprint,” Carleton President Steve Poskanzer said. “I’m grateful to all those whose careful planning, creative thinking and hard work helped us achieve this new mode of operation. This is a significant part of fulfilling our responsibility to be wise environmental stewards.”

Carleton has been pushing to the forefront of science and sustainability over the past years, whether through building a new integrated science center or transitioning to 100% carbon-neutral geothermal heating. But the work hasn’t stopped there. Now, the greenhouse facility which houses plants for biology labs, as well as faculty and student research is getting an energy-efficient upgrade. August 2020 saw the installation of new lights from Heliospectra, a leading horticultural lighting company. The company’s state-of-the-art control system will be added in May 2021, making Carleton the first small college in the country to implement the technology.
Greenhouse Supervisor Randall Hagen and Manager of Energy and Sustainability Martha Larson have been looking to replace the greenhouse’s previous 1000-Watt high-pressure sodium lights for over a year.
Zero Energy Ready project supports affordable homes and climate justice in Northfield
Housing insecurity and climate change are two wicked and intersecting challenges that disproportionately impact those least able to adapt. Hillcrest Village, a new community-driven affordable housing development in Northfield, seeks to tip these scales to meet the needs of the community’s most vulnerable residents.

“This is really about aligning climate justice and social justice into a single, tangible project that will help address homelessness, affordable housing and environment justice,” said Scott Wopata, executive director of the Community Action Center of Northfield (CAC), which is spearheading the project.
