California’s “Energy Island” Problem: Why a Hormuz Shock Lands Hardest on the West Coast

A new Forbes analysis argues California is uniquely exposed to a Strait of Hormuz disruption because the state lacks pipeline access and relies heavily on imported crude, an “energy island” reality that persists even in an era of U.S. energy abundance.

That “island” isn’t a metaphor for Californians who buy gasoline. It’s logistics. According to the California Energy Commission’s refinery receipts data, 2024 crude inputs were 23.3% from California, 13.3% from Alaska, and 63.5% from foreign sources. In other words, as local production declines, the replacement barrel usually arrives by water, either Alaska tankers or foreign supertankers docking at marine terminals, then moving to refineries via in-state pipelines.

The State’s own policy staff have acknowledged the structural constraint plainly: California’s reliance on imported oil is shaped in part by the lack of domestic oil pipelines from other states (and the high costs/controversy of rail or truck alternatives). The CEC’s refinery receipts table underscores the same point: “other states” contribute only minor volumes to the total, and the bulk of non-California crude is Alaska + foreign.

And California’s foreign crude slate isn’t abstract, it has names and flags. The CEC’s 2024 import breakdown shows top suppliers including Iraq (21.26%), Brazil (20.41%), Guyana (15.80%), Ecuador (13.60%), plus additional volumes from Saudi Arabia and the United Arab Emirates, among others. That means a meaningful share of California barrels are exposed to geopolitical and maritime choke points, especially the Persian Gulf route where Hormuz is the gate.

This week’s news cycle illustrates the risk. Markets moved sharply on escalating Middle East conflict and Hormuz-related supply fears. Reuters reported oil prices jumping nearly 5% amid elevated supply risk and tanker/insurance disruption concerns. Wood Mackenzie warned that if tanker flows don’t resume, higher oil and gas prices are “certain,” with oil potentially exceeding $100/bbl, because the Strait typically carries a major share of global oil and LNG trade.

CIPA take: California’s fuels system runs on two things: local barrels and ocean miles. When Sacramento policies kneecap in-state production and make refinery operations more brittle, the state doesn’t “go electric” overnight. It just buys the next barrel from farther away, at higher risk, with less control, and usually with weaker environmental and labor standards than California producers operate under. The Strait of Hormuz is simply the most dramatic reminder that an “energy island” pays an island tax at the pump and in volatility.
