Welcome to the  California Energy Almanac

California Residential Natural Gas Consumption

The "Residential Ave Natural Gas Use" provides info on 40 years of annual average household natural gas use, annual total residential gas use, and number of residential customers. The data shows that despite doubling the number of residential customers during the past 40 years, the annual residential total has dropped a little, but the average household use has been reduced by more than half. This is the result of our appliance and building energy efficiency standards.
