Total energy consumption, performance year:
23,029.13 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) 17,523 Kilowatt-hours 59.79 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:

Renewable electricity is generated on campus by a 13 kW and a 2 kW solar panel array. The 2 kW array produces electricity which is used in one of the dorms on campus. The 13 kW array produces electricity which in past years has been sold back to the grid and used to charge our electric carts.


Clean and renewable thermal energy (report MMBtu):
MMBtu
Clean and renewable stationary fuels used on-site to generate thermal energy 0 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:

One of the dorms on campus has a solar thermal heating system; however, the amount of energy produced by this system is not known. Three buildings use geothermal heat-pump systems as well.


A brief description of the certified/verified sources of clean and renewable thermal energy:
---

Unbundled renewable energy products (report kWh):
