The price of crude oil accounts for 55 percent of the price of a gallon of gasoline, driven by global supply and demand. The United States depends on foreign sources of oil for 62 percent of our nation's supply. By 2010, this is projected to jump to 75 percent.
In the United States, oil demand is projected to grow by 340,000 barrels per day this year and gasoline demand is projected to grow nearly two percent, averaging 9.3 million barrels per day for the summer.
