Clean and renewable electricity
| kWh | MMBtu | |
| Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) | 14,269,000 Kilowatt-hours | 48,685.83 MMBtu |
| Electricity from on-site, clean and renewable sources (rights retained/retired) | 7,201,577 Kilowatt-hours | 24,571.78 MMBtu |
A brief description of the certified/verified sources of clean and renewable electricity:
Cornell has multiple PPAs for solar PV. The facilities are located on Cornell lands. Cornell owns the environmental attributes and retires the attributes via the appropriate regulatory process for New York State thru NYGATS and RGGI. The NYSDEC determines the amount of the carbon allowance based on the documented generation. These PV Solar facilities provide renewable energy to the Ithaca Campus via remote net metering, which involves monetizing the electricity and crediting the Ithaca campus accounts.
A brief description of the on-site renewable electricity generating facilities/devices:
Cornell owns and operates two hydroelectric generators. The turbine manufacturer is Ossberger and the units are rated at 712 kw and 997 kw. In addition, there are multiple campus building with roof-top PV.
FY20 generation 98,500 kWh. On site facilites: Klarman Hall, Day Hall, Campus Store, Fernow, Human Ecology and Snee Hall

Clean and renewable thermal energy
| MMBtu | |
| Clean and renewable stationary fuels used on-site to generate thermal energy | 521,344 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:
Cornell also has a heat exchange facility (Lake Source Cooling) to produce up to 18,000 peak tons of chilled water for campus. It generates renewable cooling by exchange heat to cold water from deep in Cayuga Lake saving >80% of the energy of conventional cooling (~25 million kWhr/year, about 10% of total campus electricity usage).
Cornell has installed two solar hydronic hot water systems. The systems use the solar energy to heat water in evacuated tube solar collectors. The systems are designed to offset the need for fossil fuels to provide a portion of the heating and hot water needs of two campus facilities (23 total panels with 30 tubes each). Each tube is rated at 1,000 btu/day at peak summer solar insolation.

Unbundled renewable energy products
| kWh | MMBtu | |
| Purchased RECs, GOs, I-RECs or equivalent unbundled renewable energy products certified by a third party | 10,646,075 Kilowatt-hours | 36,324.41 MMBtu |
A brief description of the unbundled renewable energy products:
As part of the the lease supporting the Cascadilla Community Solar Farm @ Cornell University that came online in 1/20, Cornell is entitled to the project RECs.
