A brief description of the certified/verified sources of clean and renewable electricity:

Colorado Springs Utilities Green Power - bundled RECs per PPA

A brief description of the on-site renewable electricity generating facilities/devices:

Colorado College introduced its first on-campus renewable electricity project in spring of 2008. Its 22-kilowatt array was the largest solar electric system in the Colorado Springs Utilities service area at the time of permitting. During 2011/2012, CC purchased panels for the Worner Center (63,000 kWh) and in 2012/2013 for KRCC (3,240 kWh) and the Children's Center (25,200 kWh). In 2014, CC installed new solar arrays on the El Pomar Sports Center (278,000 kWh/yr), the Cornerstone Arts Center (164,600 kWh/yr), the Spencer Center (18 kW array), Synergy House (4.3 kW array), and the Dean's house (10.7 kW array). In 2015, CC installed a new solar array at the Baca Campus (31 kW array). Carbon-neutral Tutt Library (110 KW), East Campus Housing 50 KW.

Clean and renewable thermal energy (report MMBtu):

Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources 0 MMBtu

A brief description of the clean and renewable stationary fuels:

CC has a solar thermal array on the roof of the Worner Student Center.

CC also has a geothermal heating/cooling system under Tava Quad as a heat sink and source for Tutt Library and under the East campus parking lot for the East campus housing constructed in 2017.

A brief description of other sources of electricity not specified above:

1.61% of CC's electricity is sourced from what Colorado Springs Utilities refers to as "mixed market". It is a make up of the company's day-to-day purchases of resources intended to balance its electric system. It does not consist of wind, hydro or solar but does include natural gas purchases and electric purchases from neighboring suppliers to provide daily balance.
