Petroleum was the largest primary source of energy consumed in the United States in 2019, accounting for 37% of total energy consumed. In 2019, motor gasoline accounted for about 45% of petroleum products consumed in the United States. The U.S. Energy Information Administration’s (EIA) U.S. petroleum flow diagram visualizes U.S. petroleum supply (production, imports, and withdrawals from storage) and disposition (consumption, exports, and additions to storage).
Petroleum is produced from the ground as crude oil or is separated from natural gas as natural gas liquids, and then it is processed at refineries to make many different consumable petroleum products, such as motor gasoline, diesel, propane, and jet fuel. The United States consumes more petroleum than it produces; the rest is supplied by imports from other countries and from domestic stock inventories saved for later use.
