"---" indicates that no data was submitted for this field

Total energy consumption (all sources, excluding transportation fuels), performance year :
603,565.96 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:
77.96 MMBtu

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

The university has seven solar arrays. There is one array on a student house on Evanston Avenue, and five arrays on student houses on Stonemill Road.

The seventh is a demonstration unit donated by a local company. It's installed next to the RecPlex and is currently used to power the adjacent streetlights through a battery storage system designed as a student project. That array's production is not included in the above total.

In the fall of 2018, more than 1 MW of on-site solar generation was brought online, but that is after the 2017-2018 fiscal year so it is not included in this total.


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

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

NA


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:

NA


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:
3,108.33 MMBtu

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

In Dec 2017 and Jan 2018, the university purchased renewable energy in the form of RECs for LEED projects in our research institute.

Geothermal 0
Hydro 0.70
Natural gas 17.30
Nuclear 34.30
Solar photovoltaic 0.10
Wind 2.10
Other (please specify and explain below) 1.10

A brief description of other sources of electricity not specified above:

Data taken from eGRID 2014 based on PJM generation mix. This mix includes 0.6% from oil and 0.5% from other fossil fuels.


Energy used for heating buildings, by source::
Percentage of total energy used to heat buildings (0-100)
Biomass 0
Coal 0
Electricity 0
Fuel oil 0
Geothermal 0
Natural gas 100
Other (please specify and explain below) 0

A brief description of other sources of building heating not specified above:

In very few cases, there is some electric heating in the form of electric resistance heating or heat pumps, but we have no way of measuring how much energy these systems use. They are insignificant to the total.


Percentage of total energy consumption from clean and renewable sources:
0.53
