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 (2011-2015).

Luther currently hosts the largest amount of solar PV generating capacity in Iowa (1.1 MW). 33% of the electricity used by Luther College comes from renewable sources.

We are in the process of commissioning an Energy Master Plan to reduce our dependence on the coal-heavy electric grid and on our natural gas consumption. This Energy Master Plan will be completed and implemented in the fall of 2019.
