Eftersom USA:s oljeberoende ofta kommer in i diskussionen kommer några siffror här.
Citat:
The United States imported approximately 9 million barrels per day (MMb/d) of petroleum in 2014 from about 75 countries. Petroleum includes crude oil, natural gas plant liquids, liquefied refinery gases, refined petroleum products such as gasoline and diesel fuel, and biofuels including ethanol and biodiesel. In 2014, about 80% of gross petroleum imports were crude oil, and about 46% of the crude oil that was processed in U.S. refineries was imported.
The United States exported about 4 MMb/d of crude oil and petroleum products in 2014, resulting in net imports (imports minus exports) of about 5 MMb/d in 2014. Net imports accounted for 27% of the petroleum consumed in the United States, the lowest annual average since 1985.
