Total energy consumption (all sources, excluding transportation fuels), performance year :
146,538.51 MMBtu

Option 1 

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:
0.01 MMBtu

None
A brief description of on-site renewable electricity generating devices :
We have a small 3 kW array, put up by our students, on one of our satellite research buildings, and a 5 MegaWatt array which is not on line yet.

Option 2 

Non-electric renewable energy generated on-site, performance year:
82,374 MMBtu

None
A brief description of on-site renewable non-electric energy devices:
We are currently burning roughly 82,374 MMBTUs of renewable fuel oil in our central steam plant, which is a tree-offcuts-derived rapid pyrolysis product, with the carbon footprint 85% less than fuel oil. To our knowledge, we are the first college to use this product in the US. We talk about this in the innovations section. We are also burning a biodiesel blend in our smaller buildings, which equates to about 276 MMBTUs - http://www.bates.edu/news/2017/01/26/campus-construction-update-jan-27-2017/

Option 3 

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

None
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
---

Option 4 

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:
43,400.50 MMBtu

A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:
We purchase RECs for our entire electrical supply from Constellation Energy, 100% wind.
