Working for Bloomberg, we can assume that Mr. Liebreich is an economists. Economists work with a rather limited set of assumptions. That means that they have no fundamental physical models that they can use to test their estimates against. In spite of this, they have a tendency to express everything according to their tenuous economic models. As an example, Hubbert never said that demand would increase as supply was constrained, nor did he discuss price. All he said was that past a certain point depletion would assure that petroleum would become less available; there would be less to use. No price, demand needed. If it's not there, you can't use it - period!
Will future price be affected; most definitely. Oil prices have been on an upward trend for more than fifty years, and a rather steep trend since 2000. Did demand outstrip supply to force those prices higher? Except for a few brief periods, there has been no supply shortages over the last fifty years, but prices have continued to escalate. Those price increases occurred mostly during a period of rapidly expanding production. Depletion doesn’t use economic models to drive it, it is as sure and certain as
"death and taxes". It begins the first moment a resource is extracted, and continues until you can't get anymore out of the ground.
The state of the world's petroleum reserves does not revolve around economics, it is determined by its energy potential. That means it is thermodynamics that controls the world's petroleum production. Engineers have been working with thermodynamics for centuries, and in the last 150 years they have applied extensively developed, extensively tested fundamental physical models to it; the First and Second Law. Petroleum prices have increased in times of increasing supply, and now they are increasing in times of decreasing supply. To the economists that is stuck on supply and demand that makes absolutely no sense! To the engineer it is all very obvious.
Every barrel of oil that has ever been used,
on average, has required more energy to extract, process and distribute than the barrel that came before it. The Second Law guarantees that outcome! The end consumer is buying energy; he is buying energy to make his car go, train go, plane go and about anything else that moves. Petroleum supplies the energy that moves 85% of the world's transportation machinery. As time progresses the Second Law says he will get a smaller and smaller piece of that energy pie. The continual price increase that we have seen, and will see is a ramification of that phenomenon, not the cause!
Of course the economist will continue trying to apply the implements in his limited toolbox. "Rising fuel economy mandates", "demand increases", "price-elastic behavior ", and what ever. Their guesses will often go wildly astray, and sometimes like a stopped clock, right two times a day. Like the old adage,
"when the only tool one has is a hammer, every problem looks like a nail"!
