For the 12 months ending April, the California CPI rose 3.8%, matching the 12-month rise in March. In the same period, the US CPI notched down to 3.4% from 3.5% in April.

Using the same formula used by Department of Finance to calculate the California CPI, the California Food Away from Home (restaurants and take out) component rose 5.4% in April as costs continued to rise under the state’s new minimum wage, compared to only 1.1% for the US as a whole. The cost of Food at Home has been rising at a shallower rate, but at still about 60% above the overall US average.

The June average price per gallon of regular gasoline in California eased 33 cents from May to $4.85. The California regulatory and tax premium above the average for the US other than California ($3.37) eased to $1.48, a 44.0% difference.

In June, California again had the highest gasoline price among the contiguous states and DC. Californians paid $1.91 a gallon more than consumers in Mississippi, the state with the lowest price.

In June, California Energy Commission data indicates that $1.41 (30.1%) of the price of a gallon of regular gasoline was paid to cover state, local, and federal taxes and fees.

Following yet another increase in the state fuel taxes, the Energy Commission data indicates that even though the average price per gallon dropped in the first week of July, taxes and fees rose to 31.0% of the total amount paid by motorists.

Pending Air Resources Board regulations would raise these costs much higher. While Board staff has since tried to downplay the published numbers, the Board’s economic impact statement on proposed changes to the Low Carbon Fuel Standard forecasts an additional pass-through cost of 47 cents a gallon for gasoline in 2025, rising to a peak of $1.83 by 2041. Expected diesel cost pass-throughs are 59 cents in 2025 and $2.40 in 2041. Jet fuel is at 44 cents in 2025 and $1.90 in 2041.

Proposed amendments to the Air Resources Board Cap-and-Trade also are expected to raise these costs as well. On an annualized basis, the additional costs to individuals are estimated at $90 a year per person across all energy platforms, or $360 for a family of four.

The June average price per gallon of diesel in California eased 14 cents from May to $5.13. The California regulatory and tax premium above the average for the US other than California ($3.71) eased to $1.43, a 38.5% difference.

In this same period, the average US (less CA) electricity bill for all the other states grew 21.0% ($286).

In 2010, California had the 9th lowest residential electricity bill among the contiguous states and DC. In the latest data, it tied with Maine for the 13th 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.

For the 12 months ended April 2024, California’s higher electricity prices translated into Residential ratepayers paying $12.2 billion more than the average ratepayers elsewhere in the US using the same amount of energy. Compared to the lowest cost state, California households paid $15.5 billion more.
