Short-Term Energy Outlook, September 7, 2011 Release: “EIA’s economic growth assumptions have been lowered substantially compared with last month’s Outlook. This forecast assumes that U.S. real gross domestic product (GDP) grows by 1.5 percent this year and 1.9 percent next year compared with 2.4 percent and 2.6 percent, respectively, in the previous Outlook. World oil-consumption-weighted real GDP grows by 3.1 percent and 3.8 percent in 2011 and 2012, respectively, compared with 3.4 percent and 4.1 percent in the last Outlook. With weaker economic growth and lower petroleum consumption growth, EIA expects the U.S. average refiner acquisition cost of crude oil to rise from an average of $100 per barrel in 2011 to $103 per barrel in 2012, compared with an increase to $107 per barrel in 2012 in last month’s Outlook.”
