The following excerpt and graph are from the White House website:
"America’s dependence on foreign oil has gone down every single year since President Obama took office. In 2010, we imported less than 50 percent of the oil our nation consumed—the first time that’s happened in 13 years—and the trend continued in 2011.
Despite all this, Americans are still paying more at the pump when we fill up because drilling for more oil here at home won’t affect the price of gas on its own. That's why we need an all-out, all-of-the-above strategy that develops every available source of American energy."
