Total energy consumption (all sources, excluding transportation fuels), performance year :
16,466.13 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:
0 MMBtu

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

A 5.4 kW photovoltaic array is integrated into the net-zero energy, LEED Platinum Unity House -- our former president's on-campus home. Other solar PV generation on campus are from PPAs so we cannot claim the REC credits.


Non-electric renewable energy generated on-site, performance year:
1,326 MMBtu

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

Four wood pellet boilers and one wood pellet furnace are operating on campus to provide heat and hot water or hot air. An evacuated-tube solar thermal array heats domestic hot water for our Student Success Office located in the TerraHaus building. BTUs from that production have not been included here. Two solar thermal panels provide much of the hot water needed for the Unity House.


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:
0 MMBtu

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

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:
3,582 MMBtu

A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:

70% of electricity emissions are offset by the purchase of 1,100 (1.1 million kWh) green-e certified RECs provided by our energy supplier through a cooperative electricity purchasing agreement.
