The price of gasoline keeps rising for Americans, but it's not because of rising demand from consumers.
Since the first Arab oil embargo of the 1970s, the U.S. has struggled to quench a growing appetite for oil and gasoline. Now, that trend is changing.
"When you look at the U.S. oil market, you see that there's actually no growth," says Daniel Yergin, chairman of IHS Cambridge Energy Research Associates.
He says gasoline demand peaked in 2007 and has fallen each year since, even though the economy has begun to recover.
