For the 12 months ended August 2024, the average annual Residential electricity bill in California was $1871, or 88.2% higher ($877) than the comparable bill in 2010 (the year the AB 32 implementation began with the Early Action items). In this same period, the average US (less CA) electricity bill for all the other states grew only 22.6% ($308).
In 2010, California had the 9th lowest residential electricity bill among the contiguous states and DC. In the latest data, it had the 10th highest.
Residential bills, however, vary widely by region. Transforming the 2022 data recently released by the Energy Commission, estimated annual household usage is as much as 82% higher in the interior regions compared to the milder climate coastal areas, and substantially higher when comparing across counties.
