5 States With the Most Expensive Gas in the US

2. Hawaii

Price of Gas per Gallon: $4.754

Although Hawaii has no proved crude oil reserves or production, it does refine crude oil into petroleum products. The local Oahu refinery supplies much of Hawaii’s demand for petroleum products, but the state also imports refined petroleum products, including jet fuel, propane, low-sulfur diesel fuel, and motor gasoline, from countries in Asia, the Caribbean, and South America.

Energy prices in Hawaii skyrocketed after Russia’s invasion of Ukraine in 2022, which prompted Russian oil embargoes. Before the war, Russia provided about 25-30% of Hawaii’s oil.
