The Transportation Petroleum Gap
March 2, 2009
In 1989 the transportation sector petroleum consumption surpassed U.S. petroleum production for the first time, creating a gap that must be met with imports of petroleum. By the year 2030, transportation petroleum consumption is expected to grow to nearly 17 million barrels per day; at that time, the gap between U.S. production and transportation consumption will be 3.7 million barrels per day.
U.S. Petroleum Production and Consumption, 1970-2030

Note
The U.S. Production has two lines after 2005. The solid line is conventional sources of petroleum. The dashed line adds in other inputs -- ethanol, liquids from coal, and liquids from biomass. The sharp increase in values between 2006 and 2007 are caused by the data change from historical to projected values.
