Oil prices topped $150 a barrel last summer, but they're headed much lower -- to around $20, then to a "long-term equilibrium" of around $35, argues hedge-fund manager Jacques Mechelany of Bank of China (Suisse). That probably means gasoline will stay in the $1-and-change, good for consumers and business users, while frustrating solar and alternative-power investors.

"Crude oil prices could fall as low as $20 a barrel in 2009 as falling U.S. demand outstrips Chinese growth," Mechelany told the Reuters news service, via the Guardian newspaper, in this story.
