2007 AAAS Annual Meeting: February 2007 Archives

February 19, 2007

The Science of Art

Art Rosenfeld, a member of the California Energy Commission, didn't go to many sessions at this year's AAAS conference, but his vision seemed to be everywhere in the meeting's focus on efficiency. During a plenary talk a few nights ago, Berkeley Lab director Steven Chu mentioned Rosenfeld's work, even interrupting himself to say, "Hi Art," cheerfully upon seeing the senior citizen in the audience. (After the talk, the crowd mobbed the stage to pose for photos, including one local undergraduate who had asked Chu for a job over the microphone during the question session: "I hope you need an ecologist.")

Rosenfeld, spry as ever, followed AAAS then-president John Holdren as the pair raced through the exiting throng. They changed quickly into tuxedos and zoomed up to the Fairmont Hotel, where they hobnobbed with the black-tied scientific glitterati. It was a mix of business and pleasure for Rosenfeld, who's considered a kind of energy Yoda for local residents.

Social worker Barbara Budnitz, for one, wanted advice on whether the Berkeley, California, senior center on whose board she serves should install solar panels. "They're all former red-diaper babies," she joked. "I'm a big fan of solar energy," Rosenfeld answered. "For middle class families and for young people. But for seniors--not worth it." He went on to explain to a few party-goers, beaming, how California regulations encourage developers to first ensure that buildings are energy-efficient before installing solar panels.

We don’t need more fossil fuels to power the future, says Chuck Kutscher. His report, on how massive deployment of efficiency measures and renewables could cut U.S. carbon emissions by at least 60% by 2030, was well received this morning by an audience here eager for good news.

The bottom line? All we need is a hefty pricetag on carbon emissions–-Kutscher estimates about $35 per ton of carbon dioxide–-and a surfeit of political will to force people to use public transportation, build greener buildings, and pressure fossil fuel plants to become more efficient. Solarpanel Kutscher envisions the great plains blanketed with windmills, the Southwest bustling with concentrated solar power plants, and photovoltaic cells and biofuel plants all over. He says the yearlong study he presented, sponsored by the American Solar Energy Society, was “reasonable” in its assumptions, which included manufacturing limits on solar panels and market competition with fossil fuels in the wind power estimates.

Physicist Art Hobson of the University of Arkansas in Fayetteville thought the session “really ended [the AAAS conference] on a positive note … I’ve been asking myself for years, 'Can we do it with renewables and efficiency?' ” But he said that “we might need some help” to meet energy demands in the future at a feasible cost, and he figures fossil fuels could fit the bill.

Kutscher, an engineer at the National Renewable Energy Laboratory in Golden, Colorado, says Americans must be willing to pay more for the alternatives. “Does it become an entirely economic argument if you say the polar icecaps are melting?”

Salmon—Pick Your Guilt Trip

Pass by the fish counter of your local high-end supermarket, and you might see fillets of organic salmon on display. It’s still a bit of a fuzzy concept, but the label may give off planet-friendly vibes. But exactly how much greener is “organic” salmon? Seiner_1 That’s a job for what’s called life cycle analysis, a technique often used to figure out how much energy and pollution it takes to make a particular product. Now it’s being applied to fish.

Nathan Pelletier of Dalhousie University, in Halifax, Canada, took a hard look at organic and conventionally farmed salmon in a session called “Sustainable Seafood: Cradle-to-Grave Assessments of Alternative Technologies.” ...

Fishing Like an Economist

It sounds like madness: Fleets of trawlers dragging huge nets across the seafloor are driving deep-sea fish to extinction. But from a purely economic point of view, it makes perfect sense, said Elliott Norse of the Marine Conservation Biology Institute in Bellevue, Washington. “It’s not that people are stupid; they’re smart.” But while individual economic decisions make sense, another talk showed how government policies can distort the fisheries markets at the expense of these vulnerable species...

Never mind long showers, leaky toilets, or even sprawling golf courses. Agriculture is the biggest user of water in the world. Every year, the U.S. government spends millions and millions of dollars to help farmers make their irrigation more efficient. Sprinklers_1 In many cases, the goal is to reduce the amount of water diverted from rivers so that more remains for other users, including nature. But the subsidy can backfire in the long run.

“This policy is a real problem,” said Ray Huffaker, an economist at Washington State University in Pullman on Friday at a session called, “Water Crisis in Agriculture: How to Produce More with Less.” Attempts at conservation sometimes leave less water behind, Huffaker says...

Chemist Jim Hutchison of University of Oregon in Eugene this morning wanted to emphasize how research on green chemistry, while taking up time and money in the short turn, can yield cheaper techniques that won't foul the soil, air, or water.

So he showed the following two pictures to, ahem, drive the point home. Hutchinson_line_graf

"I used this one for a company in Oregon, and they didn't get it," he said of the figure of the left. The golf analogy applies, he explained, because Tiger Woods decided in early 2004 to overhaul his swing--and he lost the following 10 majors as he readjusted. "For the whole time he is doing, that he sucks," said Hutchinson. In April 2005, though, Tiger returned with a vengeance, winning the Masters, and the rest is history.

Hutchinson's analogous big win? Gold nanoparticles ...

A Late Afternoon Lift

An elevator packed with tired conventioneers was heading up to an MIT mixer--the group drawn more likely by the possibility of cold drinks rather than uncovering new research results--when a gentlemen in a beige jacket struck up a conversation with another. The first man's name? Jerry McNerney, freshly elected California Congressman and Democrat. "You're the one who beat Pombo, right?" asked a press officer from a physics lab. He was speaking of Richard Pombo, long the Republican chair of the House Resources Committee and an enemy of environmental groups, who embraced McNerney during the election. Is McNerney finding that energy issues are resonating in Congress? He's optimistic. "A lot of open minds there," said the former wind engineer. "You want my elevator speech?" he joked as the group finally filed out.

Energy Hog of the Ocean

If you worry about how much energy it takes to bring food to your dinner plate, then beware the Norway lobster (Nephrops norvegicus). Nephrops_1 It takes some 300 megajoules of energy to bring 1 kilogram of this crustacean from a trawler in the North Sea to consumers in Sweden, Friederika Ziegler of the Swedish Institute for Food and Biotechnology in Göteborg said at a session this morning. (A kilogram of bread takes 18 megajoules, by comparison.) The bulk of this energy is fuel, some nine liters of diesel per kilogram of lobster caught. “This is something of a world record for food production,” Ziegler said. Lobster caught with cages are more energy efficient, she says, but the practice is more dangerous for the fishers. Read more in a report

20 Microrumsfelds

Geologist Kerry Sieh introduced a new unit of measure yesterday during a widely talked-about speech on earthquake preparedness.

One rumsfeld, he explained, equals $100 billion per year, roughly what the U.S. has spent on average per year during the 4-year Iraq war.

Roughly $2 million--or 20 microrumsfelds--has been spent in recent years on preparing infrastructure to withstand earthquakes for the roughly half-billion people who reside between Iran and Sumatra and live in grave danger of earthquakes. Sieh, of Caltech, says he's being generous on that total, and just a few "fractions of a rumsfeld" spent by the U.S. each year could spread much good cheer for American foreign policy. "For heaven's sake, let's think about our priorities here," he told me today.

Science's Newsblog provides below some additional U.S. government sustainability expenditures in rumsfelds:

* Proposed 2008 U.S. spending on applied solar energy research ($148 million) = 1.48 millirumsfelds

* Proposed 2008 U.S. spending on nuclear nonproliferation ($1.67 billion) = about 2 centirumsfelds 

* Total 2004 developed nations aid to developing countries (about $25 billion) = a quarter-rumsfeld

* Amount per year, according to the United Nations, that some 1.1 billion people earn ($730) = $7.3 nanorumsfelds 

And, in case you're wondering:

The average National Science Foundation grant size ($150,000 per year) = 1.5 microrumsfelds.

$500 Million? Peanuts

Late Friday, a chemical engineer was complaining to me that the U.S. needs to spend an "order of magnitude" more on biofuels research, his field, if the country is to really tackle the energy challenge.

But, I asked, didn't BP just jumpstart the field with a half-billion-dollar, 10-year biofuels research center at UC Berkeley?

John_browne_180x144 "$500 million? Drop in the bucket for them. That's just a nice goodbye present for their CEO, who just left," the engineer said of BP's Lord Browne (left), who was outspoken in his calls for alternative energy and carbon emissions limits and is set to leave the firm in the summer.  "Exxon gave their CEO that huge package, and the BP guy got the research on the way out."

ExxonMobil, which made nearly $40 billion in 2006, gave CEO Lee Raymond a $400 million retirement package when he left the firm last year.
