According to a report from the federal government’s Energy Information Administration this week, U.S. crude oil production surpassed that of Saudi Arabia and Russia. When Obama made his statement in May 2011, U.S. monthly production was 174 million barrels (5.67 million barrels per day). In June 2018, monthly production stood at 320.23 million barrels (10.67 million barrels per day). […]
Domestic extraction has lowered gas prices for millions of drivers and saved them hundreds of dollars a year at the pump. A number of factors contribute to the price of gasoline, but crude oil is the largest.
In 2017, crude prices made up 50 percent of the price of gas, with federal and state taxes (19 percent), distributing and marketing (17 percent), and refining (14 percent) accounting for the rest. Over the past decade, crude oil accounted for 61 percent of the total cost of a gallon of gas.
