One of oil industry's most respected analysts is calling the BP plc. (ADR) (BP) oil spill in the Gulf of Mexico a major setback for both climate and energy policy."This is a really major setback both for climate and of course also on energy policy," Daniel Yergin, chairman of IHS-Cambridge Energy Associates told Bloomberg News. "Everything now is obviously on hold." Yergin is the author of a Pulitzer Prize-winning book on the history of the oil industry.

BP has stopped one of three leaks in the Gulf of Mexico spill, Guardian.co.uk reported Wednesday, but the accomplishment is not expected to reduce the leak's overall oil flow into the Gulf of Mexico.

The world has endured (survived?) two of them.

They led to transformations in energy use and economic activity twice in the modern era, in 1973-74 and 1979-1980.

They are oil shocks, and right now Daniel Yergin, chairman of Cambridge Energy Research Associates, argues in a Financial Times column that what is unfolding before us is the world's third oil shock. (Oil traded Thursday at $128.60 per barrel.)

Further, Yergin argues that those who say the world could take $80 per barrel oil in stride amid strong economic growth should not feel emboldened about the world's ability to continue to grow with an oil price that's $60 higher in the near future. The contraction ripples have started. In the airline sector. In the auto sector. Note the lighter traffic at your local mall. And did you notice that last food bill for the same shopping cart of items you bought?

Bad news, good news

Yergin's bad news? (And short-term, it is bad news.) Supply, short-term, will not be able to prevent the shock, in other words, lower prices to levels that would maintain (restore?) adequate global economic growth. Engineering skills and oil equipment are in short supply, drilling costs are rising, and equally damaging, selected governments are restricting access or postponing decisions that would bring more oil to the market in the shortest possible time.

Yergin's good news? Demand is already responding to record-high oil (and in the U.S., gasoline) prices, except in those countries where prices are controlled or subsidized. The oil shock is propelling changes (finally) in public policy, corporate/consumer behavior, along with technological development and implementation. Hybrid cars/vehicles, once fringe, are now in demand. The U.S. Congress increased automobile fuel efficiency requirements for the first time in 32 years. And billions of dollars have been added to speed the development of battery technology.

The markets have two additional oil industry data points to digest Friday, and through the weekend:

First the good news: OPEC (Organization of Petroleum Exporting Countries) has increased oil production in response to sustained +$90 per barrel prices.

OPEC's 10 members bound by output targets, all except Iraq and Angola, pumped 26.98 million barrels per day, up 180,000 barrels per day from September 2007, according to the survey of oil firms, traders, OPEC officials and analysts, Reuters reported Friday.
