Download Report

Below are the monthly updates from the most current July 2023 fuel price data (GasBuddy.com) and May 2023 electricity and natural gas price data (US Energy Information Administration). To view additional data and analysis related to the California economy visit our website at www.centerforjobs.org/ca.

The additional costs under California policies, regulations, taxes, and fee add-ons continue to keep prices at the highest or near the highest among the contiguous states and DC across all energy sources.

As the result of heat-related refinery issues and rising world oil prices, gasoline prices are currently trending up across the nation.  The average gasoline price in July edged up 6 cents in California and marginally higher at 8 cents in the rest of the US.  In the latest data from CSAA as of August 7, prices have risen nationally by 19 cents and by 14 cents in California.  The price increases, however, have begun to slow in part due to easing demand.
