Will fracking lead to cheap oil for all? Not necessarily

Ceteris paribus. Always with the ceteris paribus.

FT Alphaville's Kate Mackenzie has an excerpt of a very interesting research note from energy consultant Phil Verleger. The bulk of the note is a look back at the apparent vindication of MIT economist Morris Adelman, who rejected the ideas of "peak oil" at the time when they were most fashionable. Adelman, Verleger writes, accurately surmised that technological advances would mean the total reserves are far less predictable than a narrative of rising prices and increasing scarcity would imply.

But Mackenzie picks out the surprising twist in Verleger's note. While he, like so many others, points to the massive change wrought on the global energy market by the invention of fracking and other techniques for extracting unconventional reserves, he doesn't see that as leading to a predictable fall in prices. While a glut of unconventional oil would be good enough to depress prices, it couldn't simply replace the traditional OPEC countries. And the way they would deal with that squeeze could have strong repercussions:

Periods of low oil prices will undermine existing governments in nations such as Russia, Kuwait, Iraq, Algeria, Nigeria, Iran, United Arab Emirates, and Venezuela. These countries have not used oil revenues to diversify economies and build infrastructure for the post-petroleum future. Instead the monies have gone to fund larger and larger transfer (welfare) payments to mushrooming populations.

Adelman’s vindication will mean these nations must curtail such payments when they are forced to cut sales and production sharply or when prices fall. Political instability will increase as such times.

Supply and demand are complicated things. There's a reason economists love the phrase ceteris paribus – "all else being equal" – and thats because most of the time, they aren't. Fracking will introduce a downward pressure on prices, we know that. But the responses of the multifarious other producers and consumers to that pressure are chaotic and barely predictable. A simple prediction of a world of cheap oil might not be as safe a bet as it seems.

Emily Thornberry heckled by Labour MPs as tensions over Trident erupt

Shadow defence secretary's performance at PLP meeting described as "risible" and "cringeworthy". 

"There's no point trying to shout me down" shadow defence secretary Emily Thornberry declared midway through tonight's Parliamentary Labour Party meeting. Even by recent standards, the 70-minute gathering was remarkably fractious (with PLP chair John Cryer at one point threatening to halt it). Addressing MPs and peers for the first time since replacing Maria Eagle, Thornberry's performance did nothing to reassure Trident supporters. 

The Islington South MP, who voted against renewal in 2007, said that the defence review would be "wide-ranging" and did not take a position on the nuclear question (though she emphasised it was right to "question" renewal). She vowed to listen to colleagues as well as taking "expert advice" and promised to soon visit the Barrow construction site. But MPs' anger was remorseless. Former shadow defence minister Kevan Jones was one of the first to emerge from Committee Room 14. "Waffly and incoherent, cringeworthy" was his verdict. Another Labour MP told me: "Risible. Appalling. She compared Trident to patrolling the skies with spitfires ... It was embarrassing." A party source said afterwards that Thornberry's "spitfire" remark was merely an observation on changing technology. 

"She was talking originally in that whole section about drones. She'd been talking to some people about drones and it was apparent that it was absolutely possible, with improving technology, that large submarines could easily be tracked, detected and attacked by drones. She said it is a question of keeping your eye on new technology ... We don't have the spitfires of the 21st century but we do have some quite old planes, Tornadoes, but they've been updated with modern technology and modern weaponry." 

Former first sea lord and security minister Alan West complained, however, that she had failed to understand how nuclear submarines worked. "Physics, basic physics!" he cried as he left. Asked how the meeting went, Neil Kinnock, who as leader reversed Labour's unilateralist position in 1989, simply let out a belly laugh. Thornberry herself stoically insisted that it went "alright". But a shadow minister told me: "Emily just evidently hadn't put in the work required to be able to credibly address the PLP - totally humiliated. Not by the noise of the hecklers but by the silence of any defenders, no one speaking up for her." 

Labour has long awaited the Europe split currently unfolding among the Tories. But its divide on Trident is far worse. The majority of its MPs are opposed to unilateral disarmament and just seven of the shadow cabinet's 31 members share Jeremy Corbyn's position. While Labour MPs will be given a free vote when the Commons votes on Trident renewal later this year (a fait accompli), the real battle is to determine the party's manifesto stance. 

Thornberry will tomorrow address the shadow cabinet and, for the first time this year, Corbyn will attend the next PLP meeting on 22 February. Both will have to contend with a divide which appears unbridgeable.
