Gas prices may be higher in certain states due to higher state and local taxes as well as the state's distance from a gasoline supply source (e.g., refineries, pipelines, ports). Texas, for example, is the top crude oil and gas producing state in the nation in 2020 and enjoys the lowest average regular gas price ($2.92 per gallon), as of Jan. 13, 2022. Disruptions in supply and higher operating costs can also increase prices.
