Total energy consumption (electric and non-electric)
Clean and renewable energy sources
Clean and renewable electricity
| kWh | MMBtu | |
| Imported electricity from certified/verified clean and renewable sources (i.e., bundled green power purchases) | 719,425 Kilowatt-hours | 2,454.68 MMBtu |
| Electricity from on-site, clean and renewable sources (rights retained/retired) | 1,359,770 Kilowatt-hours | 4,639.54 MMBtu |
A brief description of the certified/verified sources of clean and renewable electricity:
USD purchases renewable energy through San Diego Gas and Electric’s (SDG&E) Community Choice Aggregation (CCA) program. SDG&E partners with San Diego Community Power (SDCP), a local renewable energy provider, to administer the program to City of San Diego residents and businesses. Through this program, customers have the ability to use renewable energy sources to power 100% of their electricity use. The renewable energy credits (RECs) associated with that power are assigned to the program’s customers, enabling them to account for their electricity as being 100% carbon-free. In 2023, approximately 3% of the university’s total electricity consumption received carbon-free power from the CCA program.
A brief description of the on-site renewable electricity generating facilities/devices:
Managed by GCL SOLAR, USD is home to a 1.23 megawatt solar PV system atop 11 buildings across campus. Electricity generation data from this installation is available in real time.
