California policymakers are considering state ownership of one or more oil refineries to ensure a reliable supply of gasoline as the number of refineries in the state declines.

An oil industry trade group questions whether the state would have the expertise to effectively run a refinery, citing a lack of “understanding of the industry and how it works.”

Russia. China. Venezuela. Iran. More than a dozen countries make gasoline at state-owned refineries.

Could California be next on the list?
