Actually, I have just been thinking about this. I did find this.:
California gas prices are higher than in other states due to several factors, including the state's high gasoline taxes, stricter environmental regulations requiring a special fuel blend, and a limited number of refineries. Additionally, California's isolated market means that any disruptions can lead to significant price increases at the pump.
High Taxes and Fees
- California has the highest gasoline taxes in the United States.
- Taxes and fees account for a significant portion of the price difference compared to other states.
Unique Fuel Requirements
- The state mandates a special blend of gasoline to reduce air pollution, which is more expensive to produce.
- This blend is not widely used outside California, limiting supply options during outages
