Mad MoneyNormally, I would listen to Robert Hirsch and the legendary Charlie Maxwell, over CNBC’s “Mad” Jim Cramer. But Hirsch and Maxwell are making headlines for saying $12-15 gasoline is around the corner, based on Maxwell’s projection of oil “reaching $180 a barrel in 2015 and $300 a barrel in 2020.”

Sorry, guys — every extra $40 barrel is another dollar a gallon or so at the pump. Don’t quite know how they did the math, but they did it wrong.

Help Grist raise $25,000 by September 30 to further advance our climate reporting

When Mad Money‘s Jim Cramer is the voice of sanity, you know the energy world is topsy-turvy, but I happened to catch him explaining to Matt Lauer on Today that such prices take us to $6-7 over the next few years, yes, but $12-15 gasoline requires a price of oil that the world is exceedingly unlikely to get to any time soon — $450-500 a barrel, by my estimate. The world would almost certainly go into a deep global recession long before we hit those prices.

But the situation is dire, as I’ve noted many times. The WSJ had a front page article yesterday: “Energy Watchdog Warns Of Oil-Production Crunch: IEA Official Says Supplies May Plateau Below Expected Demand,” which begins ominously:

Grist thanks its sponsors. Become one.

The world’s premier energy monitor is preparing a sharp downward revision of its oil-supply forecast, a shift that reflects deepening pessimism over whether oil companies can keep abreast of booming demand …

For several years, the IEA has predicted that supplies of crude and other liquid fuels will arc gently upward to keep pace with rising demand, topping 116 million barrels a day [MMBD] by 2030, up from around 87 million barrels a day currently. Now, the agency is worried that aging oil fields and diminished investment mean that companies could struggle to surpass 100 million barrels a day over the next two decades.

But we’ve been rising maybe 2 percent a year, so we were poised to run into 100 MMBD by around 2020. IEA isn’t alone in its concern, as I noted in my recent article on peak oil:

In October, Christophe de Margerie, CEO of French oil company Total S.A., said that production of even 100 million barrels a day by 2030 will be “difficult.” In November, James Mulva, CEO of ConocoPhillips, the third biggest U.S. oil company, told a Wall Street conference: “I don’t think we are going to see the supply going over 100 million barrels a day … Where is all that going to come from?”

Grist thanks its sponsors. Become one.

While $12-15 a gallon gas is probably a long way away — and still preventable — it looks increasingly like we dawdled too long on alternatives to avoid $6-7.

This problem cannot be solved rapidly, a point Hirsch made in “Peaking of World Oil Production,” a terrific and widely-cited study [PDF] funded by the Department of Energy in 2005 — yes, the Bush DOE — which concluded:

The world has never faced a problem like this. Without massive mitigation more than a decade before the fact, the problem will be pervasive and will not be temporary. Previous energy transitions (wood to coal and coal to oil) were gradual and evolutionary; oil peaking will be abrupt and revolutionary.

But if we are to avoid $12 gas, the next president must begin a rapid transition to advanced hybrids, especially plug-ins.
