Reading this article, I found:
"And then there is the related set of concerns: the emerging prospect that the world’s demand for oil will outstrip supply..."
(Bashes head on keyboard fifteen times.) Supply and demand are curves my friend, curves and one of them cannot "outstrip" the other. Furthermore, the quantity demanded and the quantity supplied will always match at the equilibrium price. The quantity demanded will always "outstrip" the quantity supplied at a price below equilibrium, and vice versa at a price above equilibrium. The sentence above means nothing more than, "The price of oil is likely to keep rising."
