Total energy consumption (all sources, excluding transportation fuels), performance year :
364881 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:
95.50 MMBtu

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

Williams has many solar photovoltaic arrays on campus, but most are through a power purchase agreement and we do not retain the RECs for those system. We have three systems for which we retain the RECs-- a 7.2 kw at Morley Labs and a 26.88 kw at Library shelving facility both of which are older and currently do not have working metering. The third is a 14kw system on the Log.
The Log produced 15,456.64 kwh in FY 2018.


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

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

Williams has three solar hot water systems, but unfortunately does not have metering systems on them, so the energy generated from them is not included in this total.


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:

N/A


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:
0 MMBtu

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

Williams has purchased green-e certified RECs from Community Energy in the past, but hasn't done so in a few years.
