Whether this number is justified or overblown is something experts can argue long into the night. But since October 2002, the price of oil is up 333% while global demand has risen "only" 9%, from 78 million barrels a day to 86 million now, notes veteran analyst John Olson. "This [situation] is going to get worse unless we get hit by a blunt object [to reduce oil demand]." Olson was one of several analysts and financial planners who spoke about investing in a peak-oil world at the ASPO-USA's World Oil Conference in Houston that was under way at press time. All agreed: traditional energy investing will be hugely rewarding in the near term as commodity prices rise. And, they said suppliers to alternative-energy firms make the best investments in that space-e.g., the companies that make blades and bearings for windmills, or fuel-efficient locomotive engines. "You need to think of energy as an asset class in and of itself-it warrants more than just being a part of your stock portfolio," said Seattle financial planner Jim Hansen, who now lives "off the grid."
