Not where you think. This graph is from the BP Statistical Review of World Energy, an annual report which is often more accurate than the federal Dept. of Energy.
It’s a little hard to follow the lines and arrows, so here’s the percentage breakdown for 2006, the latest data available. Note that the Middle East only accounts for about 17% of our oil imports. Makes you wonder why we have such a large military presence there. The fact that the Middle East is one of the last bastions of cheap oil probably has something to do with it.
|Oil Imports, USA (crude & refined)|
|S. & Cent. America||2708||19.89%|
|Former Soviet Union||370||2.72%|
|Other Asia Pacific||205||1.51%|
Update: New data (for 2007) is here.
