A Map of the Oil World -- The New York Times

producers, consumers and world suppliers. this a very clear indicator of
where crude comes from and where it goes.
Unfortunately, their is no indication of the consumer nations population. 
But i think we can assume the rules of the play ground that the biggest gets
the most and first do prevail.
And i was not implying that 'to each according to his needs' should  apply.
But the U.S. which in percentage of energy consumed does use 25% of the 
worlds energy might just be a tad over the top.
