Total energy consumption, performance year:
300,775.89 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) 2,108,000 Kilowatt-hours 7,192.50 MMBtu
Electricity from on-site, clean and renewable sources (rights retained/retired) 1,496,239 Kilowatt-hours 5,105.17 MMBtu

A brief description of the certified/verified sources of clean and renewable electricity:
Sac State's renewable electricity sources include solar purchased through multiple PPA's, Greenergy blocks through SMUD and Hydro-electricity through the Western Area Power Authority.

A brief description of the on-site renewable electricity generating facilities/devices:
Lot 10 and Library and Well

Clean and renewable thermal energy (report MMBtu):
MMBtu
Clean and renewable stationary fuels used on-site to generate thermal energy 557.66 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:
Sac State entered into a Power Purchase Agreement (PPA) for Solar Hot Water back in 1986. These systems are still operational to date and are still providing clean renewable hot water which is generated on site. The Solar Hot Water systems are located on the roof of Riverfront Center, Yosemite Hall North and South, and the Pool at Yosemite Hall.
American River Courtyard is one of our housing developments built in 2009 on campus. It also has a Solar Hot Water system.
All these systems play a critical part in our operational ability to reduce GHG emissions.

A brief description of the certified/verified sources of clean and renewable thermal energy:
The campus has 3 thermal hot water production systems on site purchased through a PPA.
