A brief description of the certified/verified sources of clean and renewable electricity:
---

A brief description of the on-site renewable electricity generating facilities/devices:
On-site renewable electricity facilities consist of 8 solar installations, 5 of which are smaller rooftop mounted panels and 3 of which are larger arrays installed on the ground which make up the bulk of the total.

Clean and renewable thermal energy

Clean and renewable thermal energy (report MMBtu):
MMBtu
Clean and renewable stationary fuels used on-site to generate thermal energy 158,799 MMBtu
Imported steam, hot water, and/or chilled water from certified/verified clean and renewable sources 0 MMBtu

A brief description of the clean and renewable stationary fuels:
An on-site biomass gasification plant replaces over 1.7 million gallons of #6 fuel oil used to heat the campus.

A brief description of the certified/verified sources of clean and renewable thermal energy:
The clean and thermal renewables source is our biomass gasification system which sources wood from two mills in the area who in turn source from federally regulated forest lands, or private lands with forest management plans prepared by professional foresters to meet the requirements of the Vermont Current Use program.

A brief description of the unbundled renewable energy products:
We purchase "cow power" for two buildings on campus from Green Mountain Power, which is generated by manure digestion on local dairy farms of Vermont.
