There is also some offshore oil and gas production in California , but there is now a permanent moratorium on new offshore oil and gas leasing and new offshore platforms in both California and federal waters , although new wells can be drilled from existing platforms . These restrictions were imposed after the 1969 Santa Barbara oil spill released oil into the Pacific Ocean . California produces some gas but imports most of its supply by pipeline
