Total energy consumption, performance year:
325,646.24 MMBtu

Clean and renewable electricity (report kilowatt-hours):
kWh MMBtu
Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) 0 Kilowatt-hours 0 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 0 Kilowatt-hours 0 MMBtu

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

All of Colgate's electricity is purchased from the university's local municipality and has the following generation mix:
Hydroelectricity = 88.9 percent
Nuclear = 11.1 percent
TOTAL = 100 percent

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

Clean and renewable thermal energy (report MMBtu):
Clean and renewable stationary fuels used on-site to generate thermal energy 98,541 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:

Wood chips = 8,433 tons = 97,485 MMBtus
Solar thermal (100 Broad Street) = 125 MMBtus
Geothermal Heat Exchange (Chapel House) = 931 MMBtus
TOTAL: 98,541 MMBtus

A brief description of the certified/verified sources of clean and renewable thermal energy:

Colgate purchases all of its wood chips — about 8,000 tons per year — from Gutchess Lumber Co., Inc. in Vernon, N.Y., less than 20 miles away from campus. The wood chips are a byproduct of the mill’s operations and ultimately sourced from well-managed state and private forests. This includes Gutchess’ own 29,000-acre forest, which has been owned and sustainably managed by the company for more than a century. As long as there is no land-use change, the use of Gutchess’ wood chips in Colgate’s wood boiler is a clean and renewable source of thermal energy and a climate solution.

Sustainably managed working forests can be an important aspect of combating climate change. As young trees grow, they actively capture carbon from the atmosphere, but as they age, the amount of carbon they take in decreases. Harvesting those trees makes way for new growth that can continue the cycle of carbon sequestration. The harvested trees taken to Gutchess Lumber are then milled and used in a variety of furniture and building applications, storing the carbon held within the wood for generations. Colgate's use of wood chips is a small, local operation in a state where forest biomass and tree growth continue to increase year over year.

Unbundled renewable energy products (report kWh):
kWh MMBtu
Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party 29,557,572 Kilowatt-hours 100,850.44 MMBtu

A brief description of the unbundled renewable energy products:

Colgate has chosen to purchase third-party certified RECs from organizations such as Greenlight Energy Group (https://www.gltenergy.com/) which is a best practice for institutions to mitigate its impacts associated with electricity consumption. This offset strategy ultimately helps to support renewable electricity generation while ensuring Colgate achieves carbon neutrality by 2019. Colgate purchased enough RECs to cover 100 percent of its electricity consumption even though the university's electricity is generated from emission-free sources (hydroelectric and nuclear).

Greenlight is an all-female-owned REC marketing company that has helped to provide sustainable energy purchases for a multitude of clients such as fortune 500 companies as well as college campuses.
