The International Energy Agency estimates that a price of $100 a barrel would mean U.S. imports of oil at $385 billion, and European Union imports of $375 billion. This is $80 billion in addition spending on oil imports for the U.S. and $76 billion for the E.U., compared to 2010. The impact of a $20 increase in the price of a barrel of oil translates into a 50 cent increase in price per gallon at the gasoline pump. Economic estimates show a drop of 0.5% in GDP growth for the U.S. resulting from such a price increase of $20 per barrel.
