In 2013-14, the College used a total of 48,657,329 kWh of energy from all five sources: electricity from Southern California Edison, natural gas from The Gas Company, on-campus solar photovoltaic arrays, on-campus solar hot water heating systems, and the use of on-campus diesel generators. This constitutes an decrease of -7.19% from the 2012-13 year. The first two forms of energy together cost $3.5 million. The following tables and charts provide more information about historic and current energy use.
Total Electricity Use and Sources
|Year||SCE Electricity||Natural Gas||Generators (Diesel)||Solar PV||Solar thermal||Total||Change||kWh/sq-ft||Utility cost ($ mil)|
All sources in kilowatt-hours (kWh) equivalent. * denotes estimated use/production.
Natural Gas from Southern California Gas Company
Pomona uses natural gas boilers for space and water heating and a variety of gas appliances for cooking.
Heating from solar thermal systems
The College is currently using a solar heating system to heat Pendleton Pool and to provide domestic hot water for the North Campus Residence Halls project.
Electricity from Southern California Edison
Pomona receives the majority of its electricity from Southern California Edison. This electricity comes through a substation at 6th Street and Mills Avenue, next to the Pauley Tennis Complex. Twenty-two percent of all Southern California Edison electricity comes from renewable sources, including cogeneration, geothermal, wind, and more. SCE also uses a lower-than-average amount of coal - while the state's average use of coal in an energy portfolio is 29%, coal only makes up 6% of SCE's portfolio.
Electricity from Emergency Backup Generators
Pomona has two large and a variety of small diesel emergency backup generators for use in energy emergencies, which burn diesel fuel for power. The two large generators are located next to the substation at 6th and Mills.
Electricity from Solar Photovoltaic Panel Arrays
Pomona has five photovoltaic panel arrays totaling 362 kW that produce electricity for the College - Lincoln-Edmunds, Richard C. Seaver Biology Building, North Campus Residence Halls, Grounds Facility, and South Campus Athletic Facility/Parking Structure.

* These measures refer to electricity use per cooling degree day and natural gas use per heating degree day, which provide some measure of how much energy the campus used, taking into account changes in temperature from year to year.
** Districts do not include buildings slated for construction/renovation. See Sustainability Action Plan for further description of districts and long-term energy plan.
