Book Review: <em>The Conundrum</em> by David Owen

Editor's Rating: Stars_7 A New Yorker writer catalogs the parodoxes of living green, including why driving a Prius may just make things worse

The Conundrum:
How Scientific Innovation,
Increased Efficiency, and
Good Intentions Can Make
Our Energy and Climate Problems Worse
By David Owen
Riverhead Books; 261 pp; $14

Nothing singes the psyche of an eco-conscious do-gooder quite like being rebuked by another eco-conscious do-gooder. In The Conundrum, which catalogs the hypocrisies and paradoxes of living green, the scolder is David Owen. His progressive bona fides are robust. In the 1970s, Owen moved with his new wife to Manhattan, a place he has described as a “utopian environmentalist community” because without a clothes dryer, a car, or even a lawn, their ecological footprint was minuscule. He writes frequently about the environment for the New Yorker, once arguing in its pages that an upside to the global economic crisis was that it decreased emissions. That he also writes for Golf Digest is confusing if not disqualifying.

The tough-love upbraiding in The Conundrum seems mostly directed at hybrid-driving, energy- efficient-lightbulb-screwing locavores convinced that such practices will set the world on a path to green salvation. Owen’s book brings deflating news: Most supposedly sustainable products and eco-living strategies are, he writes, “irrelevant or make the real problems worse.”

Owen’s logic is backed up by an economic principle known as the “rebound effect”: Advances in energy efficiency lower the cost of a given activity, which causes people to engage in that activity more, canceling out not only savings but also environmental benefits. Owen keeps a 1940s aluminum beer can on his desk. It weighs five times more than today’s can of Bud Light. Efficiency gains made beer cans cheaper to produce, transport, and dispose of. The cost of popping a brew declined so that more people can do it, using up more aluminum, not less.

It doesn’t take long for him to establish the Prius Fallacy: “a belief that switching to an ostensibly more efficient travel mode turns mobility itself into an environmental positive.” Owen cites statistics showing that as government officials have moved to increase automobile fuel efficiency, our gas consumption has gone up, not down. We simply drive more miles as a species. He also disses HOV lanes, traffic-control systems, and even smartphone apps for finding a parking spot as “counterproductive from an environmental point of view because they make drivers even happier with cars than they were already.”

The Conundrum is littered with other dilemmas. Air conditioners are more efficient and cheap; ergo, more homes are now air-conditioned. The more affordable lightbulbs get, the more they’re left on. Airplanes are more energy-efficient and faster than at any point in history, and therefore cheaper to fly longer distances. Owen is unafraid of questioning even that most sacred principle of guilt-free green living: eating local, organic food. Well-meaning consumers will drive minivans long distances to buy small quantities of organic food at urban farmers markets supplied by growers who make the schlep in trucks loaded at farms well beyond the suburbs. “If all the world’s groceries traveled from farm to fork in minivans, two bags at a time, we’d have exhausted many of the world’s resources long ago,” the author writes.

Owen’s short book is a contrarian page-turner and can be read in a few hours, making its ecological impact small. Even the most conscientious Whole Foods shopper will see his supposedly small footprint grow. Problems arise as Owen’s book progresses from description to prescription; the solutions offered, while ingenious, are unrealistic.

A stay-the-course, hope-for-the-best strategy is ludicrous to Owen. Instead, he’d like humans to live closer together and holds up New York City as a model. The metropolis is dense, living spaces are restricted, public transportation is (mostly) convenient, and car ownership is low. More important, he says, populations and governments should embrace strategies that effectively force reduced consumption of the planet’s natural resources. He would like us, metaphorically and perhaps actually, to drive Model T’s.

“If the only motor vehicles available today were 1920 Model T’s,” Owen writes, “how many miles do you think you’d drive each year, and how far do you think you’d live from work?” He wants to impose energy frugality by increasing fuel taxes and capping consumption. “Efficiency initiatives make no sense as an environmental strategy,” he writes, “unless they’re preceded—and more than negated—by measures that force major cuts in total energy use.”

Owen is right: The planet would be better off if we cut highway lanes and jacked up electricity rates. But he fails to answer the real conundrum: how to reverse humanity’s relentless pursuit of comfort.

David Holz's Leap Motion Wants to Kill the Mouse

Growing up in southern Florida, David Holz was a tinkerer. “I had a large pile of all sorts of electronics,” he says. “I was trying to figure out how things worked.” In high school, he built a system that uses several microphones to pinpoint where a noise originates; the U.S. military now uses similar tools to locate snipers. Holz’s project took him to the Intel International Science and Engineering Fair, but he didn’t win a prize. “I lost to somebody who cured a disease,” he says.

Holz, now 23, has moved on from sound-mapping. His new startup, Leap Motion, is dedicated to changing the way people interact with computers. Holz and his co-founder, Michael Buckwald, have built a device about the size of a cigarette lighter that contains three tiny cameras inside. It attaches to a computer and turns any PC or Mac into a gesture-recognition device. The idea is similar to the one behind Microsoft’s (MSFT) Kinect, an Xbox add-on that lets people play games just by moving their hands and body. At $70, the Leap Motion is about half the price of a Kinect. It’s also far more accurate, says Holz. The software that analyzes the images from the three cameras can track all 10 of a user’s fingers and detect movements of less than one-hundredth of a millimeter. “It’s so precise that it tracks down to the tendon,” says Andy Miller, a former Apple (AAPL) executive and now a partner at Highland Capital Partners, which has contributed to Leap Motion’s $14.5 million in funding.

Computer users have been primed for gestural interfaces thanks to Apple’s touch-based devices. Holtz envisions legions of office workers and gamers swiping, flicking, and pinching the air in front of them to interact with their machines. Such gesturing will replace the mouse, which is “a needless layer of technological complexity,” says Holz. Gesture-based computing will be particularly helpful for professionals who work with three-dimensional images, such as scientists examining molecules or energy experts studying oil-exploration maps.

Leap Motion plans to begin selling its devices within a year. They’ve also created software for third-party developers to add gesture recognition to their applications, and the duo expect roboticists, medical imagers, and gamers to take advantage of it. Holz has also been talking with consumer electronics companies about building Leap Motion technology directly into future laptops and tablets. “The end goal is to fundamentally change how people interact with their computers,” Holz says.

Even in the precocious world of startup founders, Holz stands out. He read Stephen Hawking’s A Brief History of Time in eighth grade and then devised a simple way to test the theory of general relativity. By the time he was in college, studying math at the University of North Carolina at Chapel Hill, he was doing contract work with NASA. Bill Warner, founder of video-editing software company Avid Technology (AVID), invested in Leap after being impressed by Holz’s wide-ranging intellect. Talking to him “feels like meeting Einstein when he was young,” says Warner.
