Residential Electricity Consumption

Improved more than 1 percent from
2015 to 2016

How are we doing?

Residential electricity consumption received a thumbs-up because average annual residential electricity usage in San Diego County decreased by 3% from 2015 to 2016, from 489 kWh to 475 kWh. Local consumption was comparable to other major urban coastal counties in California. San Francisco had the lowest residential electricity usage at 340 kWh per year. See more information.

Local San Diego County electricity consumption decreased from 2015 to 2016. Fresno, San Luis Obispo and Santa Clara also decreased their usage while San Francisco, with the lowest total usage, increased its average annual usage from 2015 to 2016.

Why is it important?

  • Statewide, the residential sector is responsible for 32% of electricity consumption and 35% of natural gas consumption.
  • California residents spend, on average, 30% less on residential energy compared to other states, even though it has one of the top 10 highest residential electricity rates in the country.
  • Energy-efficient buildings represent a huge opportunity to reduce greenhouse gas emissions and the energy burden on families, businesses and public agencies. Zero net energy buildings, those that produce as much energy as they consume over the course of a year, are important in reducing residential and commercial electricity usage. Learn more.

San Diego County residential electricity usage follows a similar trend as other major urban areas, spiking in the heart of the summer and rising in December and January as well. In comparison to these select counties, Fresno sees the most drastic energy use increase during the summer.

Of the different investor-owned utilities (IOUs) in California, San Diego Gas and Electric (serving 4,100 square miles of San Diego and southern Orange counties) averages less electricity use per household annually than Southern California Edison (serving 50,000 square miles of central, coastal and Southern California) and Pacific Gas and Electric (serving 70,000 square miles of central and northern California).

  Idea for Change

Residents and businesses can lower their utility bills and save energy by taking advantage of financing programs for energy efficiency and renewable energy projects with little or no upfront cost. There is a large market for rooftop solar, energy efficiency services and home upgrades, but these improvements involve capital investments that are not always affordable. The State of California has sponsored Go Green Financing, a one-stop shop designed to help property owners, renters, management companies and contractors identify and evaluate financing solutions for both their homes and businesses.

The Center for Sustainable Energy created the California Home Energy Improvement Potential Map to identify areas where homeowners are most likely to engage in energy upgrades. It helps contractors, raters and local governments target their marketing and outreach efforts by providing data for each census tract or ZIP code such as demographics, political orientation, housing characteristics, energy consumption patterns, energy program participation rates and Nielsen consumer segments.

  What are we measuring?

We measure residential electricity consumption by tracking average annual electricity use per household in San Diego County. We also compare that consumption to other California counties on an annual and monthly basis and compare consumption between the major investor-owned utilities (IOUs) in California. Learn more about the data.
