The Oil Abundance Myth

Slate looks at the American Geophysical Union's case against shale oil boosters (h/t Ritholtz):

The market is not laying the foundations for an era of unending oil-based prosperity. The market is pushing inexorably toward investment in expensive technologies to extract the last drop of profit through faster depletion of a resource that's guaranteed to run out. If we're going to invest in expensive energy technologies, it would be better to pick long-term winners rather than guaranteed losers.

The flaws in the abundance narrative for fracked natural gas are much the same as for tight oil, so I won't belabor the point. Certainly, the current natural gas glut has played a welcome role in the reduced growth rate of U.S. carbon dioxide emissions, and the climate benefits of switching from coal to natural gas are abundantly clear. But gas, too, is in a Red Queen's race, and it can't be counted on to last out the next few decades, let alone the century of abundance predicted by some boosters. Temporarily cheap and abundant gas buys us some respite—which we should be using to put decarbonized energy systems in place. It will only do us good if we use this transitional period wisely. We won't be much better off in the long run if cheap gas only succeeds in killing off the nascent renewables industry and the development of next-generation nuclear power.

Does all the new American oil give us yet another way to fry ourselves? At 0.1159 metric tons of carbon per barrel of oil, the oil in Bakken and Eagle Ford amounts to a carbon pool of 81 gigatons, and the Green River shale adds up to 232 gigatons. Given that burning an additional 500 gigatons of fossil fuel carbon is sufficient to commit the Earth to a practically irreversible warming of 2 degrees Celsius, these are scary numbers.

I don't believe the shale oil optimists' claims, but I'm still waiting to see the peak in production in the Bakken.  It may be a few years off, but once that comes, I think the boosters will have a much tougher case to make.  As for the Green River shale, I don't think we'll see any positive benefit from that.  If people think the oil sands are an environmental disaster, Green River is even worse.
