Total energy consumption (all sources, transportation fuels excluded), performance year:
13,524 MMBtu

Clean and renewable energy from the following sources::
Performance Year
Option 1: Clean and renewable electricity generated on-site during the performance year and for which the institution retains or has retired the associated environmental attributes 20 MMBtu
Option 2: Non-electric renewable energy generated on-site 1,060 MMBtu
Option 3: 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 0 MMBtu
Option 4: Purchased third-party certified RECs and similar renewable energy products (including renewable electricity purchased through a certified green power purchasing option) 3,400 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 president's on-campus home. Other solar PV generation on campus are from PPAs so we cannot claim the REC credits.

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

Six wood pellet boilers are operating on campus to provide heat and hot water.
An evacuated-tube solar thermal array heats domestic hot water for our ten-student TerraHaus residence. BTUs from that production have not been included here. Two solar thermal panels provide much of the hot water needed for the Unity House.

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

A brief description of the RECs and/or similar renewable energy products:

99% of electricity emissions are offset by the purchase of 1,000 (1 million kWh) green-e certified RECs provided by our energy supplier through a cooperative electricity purchasing agreement.
