Data source(s) and notes about the submission:

Nearly 85 percent of Luther’s carbon footprint is associated with the energy we use on campus. Electricity purchases from our coal-intensive part of the U.S. electrical grid account for 51 percent of our greenhouse gas emissions. The direct combustion of fossil fuels in our heating plant and fleet vehicles represents another 33 percent.

Luther College has invested in several renewable energy systems to heat and power our campus and reduce our greenhouse gas emissions. These investments include geothermal energy systems at Baker Village (1999) and the Center for the Arts (2003), a 1.6 megawatt (MW) wind turbine on the bluff west of campus (2011), and several solar photovoltaic (PV) systems (2011-2020).

Luther currently hosts 2 MW of solar capacity. 55% of the electricity used by Luther College comes from renewable sources.

We commissioned an Energy Master Plan in 2019 to examine ways to reduce our dependence on consuming fossil fuels for the HVAC needs of campus. This plan relies on migrating to low temperature hot water loops and chilled water loops to feed our buildings. While the plan has been created, we are working on how to implement it in the future. It will rely on a combination of geo-thermal energy to feed the loops, as well as some existing chillers.
