Total energy consumption, performance year:
65,371.12 MMBtu

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 0 Kilowatt-hours 0 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 266,671.47 Kilowatt-hours 909.88 MMBtu

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

A brief description of the on-site renewable electricity generating facilities/devices:
The college provides space for four investor-owned solar arrays on campus, specifically: one ground mounted array on the Gellerstedt Soccer Field, and three rooftop arrays on the Facilities Building, Bullock Science Center, and Parking Deck. Though these arrays are housed on campus, we do not directly consume power generated by these solar projects. The power is sold by the investors to Georgia Power for the utility’s power supply and the total estimated power produced is enough to power 31 average US homes. In the legal leasing agreement with the investors, Agnes Scott retained the environmental attributes for the arrays. The college owns a single array on the roof of the Bradley Observatory, and the electricity generated goes directly to the building. This array is used as a living laboratory for student learning and research.

Clean and renewable thermal energy (report MMBtu):
Clean and renewable stationary fuels used on-site to generate thermal energy 1,623.89 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:
Campbell Hall uses a hybrid-geothermal ground-source heat pump to heat and cool the building. The residual heat from the system is used to heat the hot water for the residential half of the building. The hybrid-geothermal ground-source heat pump has been operating since April 2014. During the renovation of Rebekah Scott Hall in 2018, a second hybrid-geothermal ground-source heat pump was installed to both heat and cool the building and heat the residential hot water. The geothermal field for this project replaced an impervious parking lot and now is landscaped with native, drought tolerant plants. As of 2018, 10% of the campus is heated/cooled with geothermal energy.
