where does the united states buy oil from
Petroleum in the United States In 2014, petroleum and natural gas were the two largest sources of energy in the U.S., together providing 63 percent of the energy consumed (oil provided 35 percent and gas 28 percent).[6] In 2008 the United States consumed 19.5 million barrels (3,100,000Â m3) per day of petroleum products, of which 46 percent was gasoline, 20 percent diesel fuel and heating oil, and 10 percent liquefied petroleum gas.[7] In 2015, the U.S. imported 24% of the petroleum it used, the lowest since 1970.[8] The largest sources of U.S. imported oil were: Canada (40%), Saudi Arabia (11%), Venezuela (9%), Mexico (8%), and Colombia (4%).[9]
Standard Oil Standard Oil Co. Inc. was an American oil producing, transporting, refining, and marketing company. Established in 1870 by John D. Rockefeller and Henry Flagler as a corporation in Ohio, it was the largest oil refinery in the world of its time.[7] Its controversial history as one of the world's first and largest multinational corporations ended in 1911, when the United States Supreme Court ruled that Standard Oil was an illegal monopoly.
