Total energy consumption (all sources, excluding transportation fuels), performance year :
158,907.94 MMBtu

Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
1,984 MMBtu

A brief description of on-site renewable electricity generating 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).


Non-electric renewable energy generated on-site, performance year:
135 MMBtu

A brief description of on-site renewable non-electric energy devices:

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


Total clean and renewable electricity generated by off-site projects that the institution catalyzed and for which the institution retains or has retired the associated environmental attributes, performance year:
1,859 MMBtu

A brief description of off-site, institution-catalyzed, renewable electricity generating devices:

CC owns 200 kW in the Bradley Community Solar Array as part of the Clean Energy Collective. Additionally, CC owns 250 kW of the Colorado Springs Solar Garden.


Total third-party certified RECs, GOs and/or similar renewable energy products (including renewable electricity purchased through a utility-provided certified green power option) purchased during the performance year:

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

2.85% 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.
