Origin of United States Imports of Crude Oil: The United States consumes three times more oil than it produces, and consumes most of the oil produced by neighbors Canada and Mexico as well. However, even these resources are not enough. In order to fuel its oil addiction, the United States must import from unstable and/or state-owned oil companies in Saudi Arabia, Venezuela, and Nigeria, among others. Worldwide, the top five net exporters of oil are Saudi Arabia, Russia, Norway, Iran, and Venezuela.
