Jun 8, 2011 (The Archdruid Report) -- Last week’s discussion of the twilight of the electrical grid in an age after abundance turned out to be timely, in an ironic sort of way.
Whatever conversations it might have set in motion in the peak oil blogosphere were all but drowned out by a flurry of proclamations that some energy resource or other would keep the grid up and running for the foreseeable future.
Mind you, some of that flurry could have been lifted straight from equivalent discussions in the alternative energy field three decades ago. Fans of nuclear power were busy promoting their glow-in-the-dark solutions, of course, though for some reason fusion didn’t get dragged into the discussion; the folks at Livermore must have been busy doing something else this week. Meanwhile a longish essay posted on The Oil Drum, and widely cited elsewhere, insisted that satellite based solar power was the solution to the future’s energy problems. For connoisseurs of energy vaporware, this essay was a treat – a Dagwood sandwich of untried technologies, enthusiastic assumptions, and more than Panglossian optimism concerning the potential costs and downsides of pursuing a wholly untested and dizzyingly grandiose technological project at a time when the industrial world is so far into bankruptcy that it’s scrambling to keep its existing infrastructure from crumbling under its collective feet.
Still, the chief focus of the discussion was less dated, though attentive observers will have seen it coming some time ago. "Fracking" technology – more properly, "hydrofracturing," but only engineers call it that these days – is part of the toolkit that’s used to extract fossil fuels, and it’s become all the rage among those who want to believe that the age of cheap abundant energy isn’t dead yet. Thus there’s been a great many claims insisting either that natural gas will fuel our current lifestyles for the foreseeable future, or that it will provide a bridge to a future of renewable energy that will, again, keep our current lifestyles supplied with all the power we think we need.
Now of course fracking is a reality, and one that’s had a significant impact on natural gas production in the US already. Those of my readers who, in their younger days, shook up a bottle of soda pop good and hard, and then opened the cap, already know a good deal about the fracking process. Instead of shaking gas-bearing rock, fracking pumps in a mixture of water and toxic chemicals under high pressure, but the result is the same: bubbles of gas that were trapped in the rock (or the soda pop) come bubbling out all at once. If you want a sudden fountain, it’s not a bad approach, but anyone who’s tasted soda out of a thoroughly shaken bottle knows part of the downside: you get most of the gas in that first big splash, and very little is left behind.
