Climate change: Scientists say there is hope

By Laurie Goering
The Seattle Times

May 5, 2007

BANGKOK, Thailand — A U.N. panel that has laid out doomsday global-warming scenarios offered some good news Friday: Climate change can be limited, and scientists think it can be done at a reasonable price.

Just as important, the report says, existing technology will do most of the job, if policymakers act quickly. And average citizens can make valuable contributions by adopting small lifestyle changes.

Skeptics, including the Bush administration, said the most stringent recommended measures could strain the world economy. Others doubted the worst-polluting nations would cooperate.

“It’s not realistic from a political standpoint, and it’s not realistic because those targets are incredibly expensive,” said Robert Mendelsohn, a Yale University economist.

Even supporters of the plan were daunted by the speed and scale of action required by the report to stabilize carbon emissions at roughly current levels.

Still, scientists and government delegates involved in the report said they hoped it would serve as a basis for climate discussions at a Group of Eight summit in June and at a U.N. climate summit in December.

The new report

A summary of the new report says the world must significantly cut emissions of carbon dioxide and other greenhouse gases by:

Sharply improving energy efficiency in buildings, vehicles and kitchen appliances.

Shifting from fossil fuels to nuclear, wind, solar and other renewable energy sources.

Capping agricultural emissions.

The latest report by the Intergovernmental Panel on Climate Change, released Friday, “addresses a fundamental concern of Americans: Can we do something about this?” said Peter Altman, a climate expert at the National Environmental Trust, a nonpartisan nonprofit established to inform citizens about environmental problems and how they affect health and quality of life. “The answer is a resounding yes.”

By rapidly ramping up use of renewable-energy sources such as solar, wind and hydroelectric power, making cars, homes and factories more energy efficient, producing electricity with natural gas rather than coal and sequestering carbon dioxide below ground, worldwide temperature increases could be limited to about 3.6 degrees Fahrenheit, low enough to avoid potentially disastrous droughts, severe storms and sea-level rise, the report’s summary said. By comparison, global temperatures have risen about 1.5 degrees since the beginning of the Industrial Revolution in the 18th century.

Previous reports

The new Intergovernmental Panel on Climate Change (IPCC) report follows two earlier U.N. climate statements this year:

The first concluded that human activity, particularly the burning of fossil fuels, is almost certainly driving global warming. Summary: www.ipcc.ch/WG1_SPM_17Apr07.pdf

The second laid out expected effects of climate change, including more severe and erratic weather, rising sea levels, more flooding and droughts, species extinctions and changes in agricultural production. Summary: www.ipcc.ch/SPM13apr07.pdf

Just as important, substantially cutting greenhouse-gas emissions to levels scientists think would stem increases in warming would cost nations at most 0.12 percent of economic growth each year through 2030, scientists said.

“The bottom line is, all it takes to beat this problem is the political will to put the solutions in hand to work and to invest in clean-energy solutions for the future,” Altman said. “To do this at about a tenth of a percent of GDP per year is a very low-cost investment for something with tremendous payoff.”

GDP, or gross domestic product, measures the value of all goods and services produced within a nation and is considered the best barometer of the country’s economic fitness.

Bush administration officials, who along with representatives of 120 other countries and 2,000 scientists approved the report’s policy summary, praised it for highlighting “the importance of deploying a portfolio of clean-energy technologies.”

But they said trying to cut greenhouse-gas emissions by 50 to 85 percent by 2050, in line with the report’s most ambitious scenarios, would have economic consequences.

The report’s primary instrument for reducing such concentrations is a system in which governments would cap emissions and charge polluters for every ton of carbon dioxide beyond that point. That would force companies to cut emissions and invest in energy efficiency and alternative fuels.

The price per ton would reach as high as $100 by 2030. By then, the system could cost up to 3 percent of the world’s gross domestic product, the report said.

James Connaughton, chairman of the White House Council on Environmental Quality, said the highest-cost scenario “would, of course, cause global recession, so that is something that we probably want to avoid.”

Those costs, however, could drop significantly if the world reaps other benefits from reduced emissions, including more healthful air, greater energy security as reliance on foreign oil drops and export opportunities as newly developed technology is sold and adopted elsewhere, the report’s authors said.

The report, the third in a series of U.N. climate-change studies this year, is the first aimed at analyzing solutions.

It suggests major drops in emissions are possible through switching to natural gas rather than coal as a source of electricity, using hybrid and fuel-efficient vehicles, incorporating active and passive solar design into buildings, using more insulation and energy-efficient appliances in homes, improving industrial energy efficiency and encouraging the use of renewable energy sources.

Capturing and storing carbon-dioxide emissions also could lower atmospheric concentrations of the gas, the authors said.

Nuclear power, a controversial alternative to fossil fuels, probably will not gain wide acceptance, if only because of its high cost compared with other options, the report said.

The document also examines a range of policies shown to be effective in promoting emissions reductions, from fuel, road and auto taxes to energy-efficiency standards for appliances, subsidies for renewable energy, mandatory fuel-efficiency standards, investment in public transportation and tax credits.

Voluntary agreements by industries to cut emissions, a favored measure in the United States, for the most part “have not achieved significant emissions reductions beyond business as usual,” the report notes, although a few recent efforts have been exceptions.

Probably the easiest and cheapest way to cut greenhouse-gas emissions, the report’s authors said, is to focus on improving energy efficiency.

But other key strategies will be ensuring that massive expected growth in developing nations, is cleaner and more sustainable, and that people everywhere cut consumption and emissions without waiting for politicians to act.

That could mean everything from putting on a sweater rather than turning up the heat to buying a hybrid car, choosing a house on a public-transportation line or hanging laundry out to dry rather than throwing it in a dryer.

“It does require lifestyle changes but not any sacrifices,” said Jayant Sathaya, a senior energy-technology scientist at the University of California, Berkeley, and one of the report’s authors.

The report warns that failure to take quick action to cut greenhouse-gas emissions could lead to concentrations of in the atmosphere more than doubling from the current 425 parts per million by 2100, increasing worldwide average temperatures up to 11 degrees.

A recent European study suggests that if countries fail to stem climate change quickly, they eventually could spend between 5 and 20 percent of their income each year trying to combat its effects.

New climate report: “highway to extinction”

By Seth Borenstein
The Seattle Times/Associated Press

April 1, 2007

WASHINGTON — A key element of the second major report on climate change is a chart that maps out effects of global warming with every degree of temperature rise, most of them bad.

There’s one bright spot: A minimal heat rise means more food production in northern regions of the world.

However, the number of species going extinct rises with the heat, as does the number of people who may starve, or face water shortages, or floods, according to the most recent draft obtained by The Associated Press.

Some scientists are calling this degree-by-degree projection a “highway to extinction.”

The Intergovernmental Panel on Climate Change 20-chapter draft report, to be released Friday, likely will be the source of sharp closed-door debate, some scientists say. While wording in the draft is almost certain to change, several scientists say the focus won’t.

An earlier draft obtained by The Associated Press was published March 11 in The Seattle Times.

The final document will be the product of a U.N. network of 2,000 scientists as authors and reviewers, along with representatives of more than 120 governments. It will be the second of a four-volume assessment of Earth’s climate.

The first report, released in early February, concluded that scientists are 90 percent certain that people are the cause of global warming and that its effects are being felt and will continue for centuries.

University of Victoria climate scientist Andrew Weaver said the chart of results from various temperature levels in the upcoming report is “a highway to extinction, but on this highway there are many turnoffs. This is showing you where the road is heading.”

The report says global warming already has degraded conditions for many species, coastal areas and poor people.

But as the world’s average temperature warms from 1990 levels, projections become more dire. Add 1.8 degrees Fahrenheit and between 400 million and 1.7 billion extra people can’t get enough water, some infectious diseases and allergenic pollens rise, and some amphibians go extinct. The food supply, especially in northern areas, also could increase. That’s the likely outcome around 2020, according to the draft.

Add another 1.8 degrees and as many as 2 billion people could be without water and about 20 percent to 30 percent of species near extinction. Also, more people start dying because of malnutrition, disease, heat waves, floods and droughts. That would happen around 2050, depending on the level of greenhouse gases from the burning of fossil fuels.

At the extreme end of projections, a seven- to nine-degree average temperature increase, the chart predicts: “Up to one-fifth of the world population affected by increased flood events … “1.1 to 3.2 billion people with increased water scarcity” … “major extinctions around the globe.”

Several scientists involved in the process say they are optimistic that such a drastic temperature rise won’t occur because carbon-dioxide emissions that cause global warming will be reduced.

“The worst stuff is not going to happen because we can’t be that stupid,” Harvard University oceanographer James McCarthy said. “Not that I think the projections aren’t that good, but because we can’t be that stupid.”

Details on the group’s first report were provided by Seattle Times archives.


Warming report casts grim shadow on future

By Seth Borenstein

The Seattle Times/Associated Press

March 11, 2007

WASHINGTON — The harmful effects of global warming on daily life already are evident, and hundreds of millions of people won’t have enough water within a couple of decades, top scientists will say next month at a meeting in Belgium.

At the same time, tens of millions of others will be flooded out of their homes each year as Earth reels from higher temperatures and sea levels, according to portions of a draft of an international scientific report obtained by The Associated Press.

Tropical diseases such as malaria will spread. By 2050, polar bears mostly will be found in zoos, their habitats gone. Fire ants and other pests will thrive.

For a time, food will be plentiful because of a longer growing season in northern regions. By 2080, though, hundreds of millions of people could face starvation, according to the report, still being revised.

The draft document by the authoritative Intergovernmental Panel on Climate Change, a U.N.-organized network of 2,000 scientists established in 1988 to give regular assessments of Earth’s environment, focuses on global warming’s effects and is the second in a series of four reports this year. Written and reviewed by more than 1,000 scientists from dozens of countries, it still must be edited by government officials.

But some scientists said the overall message is not likely to change when issued in early April. Their plan will be presented to President Bush and other world leaders at a summit in June.

The first report, released early last month, concluded that scientists are 90 percent certain that people are the cause of global warming, that its effects are being felt and that it will continue for centuries. The report also noted that atmospheric carbon-dioxide levels are at their highest in 650,000 years, average global temperatures have risen about 1.3 degrees since the industrial age began and sea level rose nearly 7 inches during the 20th century, with the rate of rise more than doubled in the past decade.

The latest report — considered by some scientists the “emotional heart” of climate-change research — focuses on how global warming alters the planet and its life.

“This is the story. This is the whole play. This is how it’s going to affect people. The science is one thing. This is how it affects me, you and the person next door,” University of Victoria climate scientist Andrew Weaver said.

The scientists offer a ray of hope. The report says many — not all — of the predicted effects can be prevented if within a generation the world slows its emissions of carbon dioxide and if the level of greenhouse gases sticking around in the atmosphere stabilizes. But the scientists note that what’s happening now isn’t encouraging.

“Changes in climate are now affecting physical and biological systems on every continent,” the report says, in marked contrast to a 2001 report by the same international group that said the effects of global warming were coming, but only with scattered regional effects.

“Things are happening and happening faster than we expected,” said Patricia Romero Lankao of the National Center for Atmospheric Research in Boulder, Colo., one of many co-authors of the new report.

The document says scientists are highly confident that many current problems — change in species’ habits and habitats, more-acidified oceans, loss of wetlands, bleaching of coral reefs, and increases in allergy-inducing pollen — can be blamed on global warming.

For example, the report says North America “has already experienced substantial ecosystem, social and cultural disruption from recent climate extremes,” such as hurricanes and wildfires.
But the present is nothing compared with the future.

Global warming soon will “affect everyone’s life … it’s the poor sectors that will be most affected,” Romero Lankao said.

And co-author Terry Root of Stanford University said: “We truly are standing at the edge of mass extinction” of species.

Looking at different impacts on ecosystems, industry and regions, the report sees the most positive benefits in forestry and some improved agriculture and transportation in polar regions. The biggest damage is likely to come in ocean and coastal ecosystems, water resources and coastal settlements.

The hardest-hit continents are likely to be Africa and Asia, with major harm also coming to small islands and some aspects of ecosystems near the poles. North America, Europe and Australia are predicted to suffer the least harm.

“In most parts of the world and most segments of populations, lifestyles are likely to change as a result of climate change,” the draft report said. “Net valuations of benefits vs. costs will vary, but they are more likely to be negative if climate change is substantial and rapid, rather than if it is moderate and gradual.”


U.N. gets plan to stave off worst effects of global warming

By Robert Lee Hotz

Los Angeles Times Staff Writer

February 28, 2007

UNITED NATIONS — Wrenching worldwide climate changes can no longer be avoided, but there is still time to stave off the worst consequences of global warming, an international research team said Tuesday.

The scientists from 11 countries urged sweeping conservation measures to hold the expected increase in temperatures to no more than an average of 3.6 degrees Fahrenheit — less than half the expected increase if emissions of greenhouse gas and soot continue unabated.

Based on two years of study, the scientists called for bold actions, including carbon taxes, a ban on conventional coal-fired power plants and an end to beachfront construction worldwide.

The researchers were financed by the nonprofit United Nations Foundation and the 60,000-member research society Sigma Xi.

“Unlike many reports from scientists, this report gives very clear recommendations for what the international community and nations themselves must do to mitigate and adapt to climate change,” said biodiversity expert Peter Raven, director of the Missouri Botanical Garden, who helped prepare a Sigma Xi study.

With its emphasis on policy recommendations, the panel’s effort marks a shift in the international politics of pollution and climate change, analysts said. Researchers are no longer debating whether human-induced global warming is genuine, but have begun the painstaking process of negotiating international agreement on what to do about it.

Their effort comes on the heels of a landmark United Nations report last month that concluded rising temperatures would continue to increase even if greenhouse gas emissions could be held to current levels.

Global temperatures have increased about 1.4 degrees Fahrenheit over pre-industrial levels, the researchers said. To meet the scientists’ goal, global CO2 emissions must level off by 2015 and drop by two-thirds of that level by 2100.

They urged stricter fuel efficiency standards, as well as fuel taxes, registration fees and rebates that favor more efficient transportation, which today is responsible for 40% of the world’s carbon emissions.

A 20-fold improvement in car efficiency is well within existing technology, they said. Moving freight by rail instead of truck could also cut emissions substantially.

The researchers also recommended the expanded use of biofuels to reduce dependence on the oil that accounts for one-quarter of the world’s CO2 emissions. They endorsed broader use of nuclear power, if it can be made safer. Energy research budgets worldwide ought to triple, they said.

In addition, the scientists called for improved designs of energy-efficient appliances, office equipment and “greener” commercial and residential buildings. Taken together, the heating, cooling and lighting of buildings accounts for about 30% of the world’s greenhouse gas emissions.

Most tellingly, the panel called for a ban on any new coal-fired power plants that cannot be equipped to capture and store the carbon dioxide they emit.

All told, the U.S., China and India plan to build about 850 coal-fired plants over the next decade, which by environmentalists’ calculations would pump as much as five times more carbon dioxide into the atmosphere than international control measures aim to eliminate.

No matter what people do to reduce soot or curtail emissions of carbon dioxide and other greenhouse gases, the world will continue to warm somewhat, and people will have to adapt, the researchers said.

To minimize the hazards of rising sea levels and more powerful storms, the group called for a worldwide ban on beachfront construction near existing high-tide lines.

To reduce the effects of climate-related disasters, such as floods or prolonged droughts, the panel urged better international emergency response measures, warning that there may be as many as 50 million environmental refugees by 2010.


Mr. Green: Environmentalism’s most optimistic guru

By Elizabeth Kolbert

The New Yorker

1/22/2007

Amory Lovins’s home, which also serves as his office and “bioshelter,” is open for self-guided tours weekdays from nine o’clock in the morning until four in the afternoon. Built into a mountainside above Snowmass, Colorado, it has curved stone walls, a flat roof, and several sets of solar panels, some of which rotate to track the angle of the sun. The building’s double-paned windows are lined with a polyester film that allows visible light to pass in but prevents thermal radiation from getting out, and the space between the panes has been filled with krypton. Although wintertime temperatures on the mountain routinely drop below zero, the building has no furnace; it is warmed by sunlight and by heat that has been collected in, among other places, a pond that lies between the Xerox machine and the dining room. The first time I visited, Lovins had just finished doing some laundry in his front-loaded, energy-saving washing machine. He took the damp clothes out of the washer and hung them in a little glass-ceilinged room. It was a bright blue morning, and Lovins predicted that the clothes would be ready to wear by nightfall. In the winter, if the sky is overcast, it can take up to two days for items like bluejeans to dry completely, but this is no problem, he assured me, provided one is capable of thinking more than twenty-four hours in advance.

Lovins is a short man with a salt-and-pepper mustache, a fringe of tousled black hair, and droopy brown eyes that give him a passing resemblance to Einstein. He wears Coke-bottle eyeglasses, a necklace of turquoise beads, and a watch that is supposed to prevent jet lag by sending out an electromagnetic signal exactly the same frequency as the earth’s. He is routinely described, even by people who don’t particularly like or admire him, as a “genius.”

Lovins first came to national attention in 1976, when he was twenty-eight. In an essay published in Foreign Affairs, he asserted that the United States could completely phase out its use of fossil fuels and do so not at a cost but at a profit. “We stand here confronted,” he wrote, quoting Pogo, “by insurmountable opportunities.” At the time, the country was in the midst of what might now be called the first energy crisis, and the article created a stir; testifying on Capitol Hill, Lovins emerged as the demand-side management version of a rock star. Symposia were held to debate his ideas, and critiques were published by, among others, they physicist and Nobel Laureate Hans Bethe. (Lovins, in turn, wrote a response twice as long as Bethe’s critique and Bethe conceded several points.)

Thirty years later, the world faces another energy crisis, and Lovins still sees limitless opportunity. He maintains that the U.S. can eliminate its use of oil by 2050, even while reducing its coal and natural-gas consumption, enjoying unprecedented prosperity, and preserving the Arctic National Wildlife Refuge. Although Lovins was one of the first to appreciate the dangers of global warming, he believes that the problem seems so daunting only because those studying it have got the math wrong. “Climate protection, like the Hubble space telescope, has been spoiled by a sign error,” he told me.

Lovins is a prolific writer – of books, of articles, and of technical treatises. During my first visit with him, he informed me that he had picked out a few of the most important ones for me to take home: papers on topics like microgeneration, “super-efficient” building practices, and data-center design were arranged in stacks that covered nearly the entire surface of a large dining-room table. That day, we ended up talking for several hours, and as I was packing up my things to go Lovins went to check on his laundry. It was nearly dry, he reported cheerfully. As I was driving back down the mountain in my rental car, it occurred to me that Lovins might be the most impractical person I had ever met. Then it occurred to me that he might be the only truly practical one.

This year, Americans will consume close to four trillion kilowatt hours of electricity. In addition, we will burn through a hundred and forty-three billion gallons of gasoline, which at current retail prices will cost us some three hundred and sixty billion dollars, and twenty-six billion gallons of jet fuel, worth fifty billion dollars. To heat our homes and businesses this winter, we will purchase sixty-two billion dollars’ worth of natural gas and heating oil, and just to grill our weenies we will buy some seven hundred and seventy-one million dollars’ worth of charcoal briquettes. In 2007, total energy expenditures in the U.S. will come to more than a quadrillion dollars, or roughly a tenth of the country’s gross domestic product.

With so much at stake, basic economics suggest that any significant inefficiencies should have been wrung out of the system long ago. It follows that further efforts will cost more than they will return. This reasoning is pervasive in the U.S., its most prominent spokesman being Vice-President Dick Cheney, who once dismissed energy conservation as a “sign of personal virtue.” Lovins’s fundamental premise is that this fundamental premise is wrong.

“You know, there’s this old joke about the economist who’s taking his mannerly granddaughter for a walk,” he told me. “She says, ‘Oh, Grandpa, I see a twenty-dollar bill lying in the street. May I go pick it up, please?’ He says, ‘Don’t worry, my dear. If it were real, somebody would have picked it up already.’” Lovins likes to say that he takes economics “seriously, not literally.” In his view, the streets are littered with twenty-dollar bills.

Lovins makes his living as the C.E.O. of the Rocky Mountain Institute, a consulting firm that he founded twenty–five years ago with his wife at that time, Hunter. R.M.I. used to operate out of Lovins’s Snowmass home; in recent years it has outgrown these quarters – it now employs more than fifty people – and has expanded into new offices, some in Boulder and the rest down the road from his house, in a building that once belonged to a foundation created by John Denver. Lovins calls the firm an “entrepreneurial non-profit,” and its state goals, which he often recites work for word, is to foster “the efficient and restorative use of resources to make the world secure, just, prosperous, and life-sustaining.” Some of R.M.I.’s clients embrace this goal in its entirety, others at best selectively. (While I was visiting Lovins, he delivered the “efficient and restorative” spiel to a representative of the Singaporean government who had come to discuss manufacturing; her response was to giggle nervously.)

R.M.I., for its part, does not demand commonality of purpose. In “Why We Work with the Military,” an essay posted on R.M.I.’s Web site, Lovins rejects the criticism – sometimes voiced by his own employees – that by consulting for the Department of Defense the institute is simply helping to kill people in a more energy-efficient manner.” “A molecule of oil burned or carbon dioxide released has the same consequences no matter who used it,” he observes. Other R.M.I. clients have included San Diego Gas & Electric, Royal Dutch Shell and Anglo American PLC, one of the world’s largest mining companies. A few years ago, Texas Instruments hired R.M.I. to help design a new chip-manufacturing plant in Richardson, Texas. It is expected to use twenty per cent less energy and thirty-five per cent less water than a typical chip factory of comparable size. It also cost thirty per cent less to build.

“Amory doesn’t take a bullying, negative approach,” Paul Westbrook, Texas Instruments’ manager for sustainable development, told me. “He just says, ‘Here’s a better way, and here’s why it works.’ And you think, Well, we’d be kind of dumb not to do that.” One of the ways the new Texas Instruments plant will save energy is by capturing heat that normally would have been discarded as waste. “We implemented heat recovery, and, lo and behold, we didn’t need as many boilers,” Westbrook said.

A lot of Lovins’s ideas sound radical and futuristic – ultra-light cars made of carbon fibres, vehicles that generate electricity when they’re not on the road, an economy powered by hydrogen. At the same time, he is a passionate advocate of what he calls “good, old-fashioned Victorian engineering,” and believes that a great many problems can be solved using high-school physics. (Lovins can spend hours describing the energy savings that follow from steps as simple as increasing the diameter of pipes.) This combination of high- and low-tech enthusiasms makes his outlook difficult to categorize. Once, when I casually used the phrase “thinking outside the box,” Lovins interrupted me. “There is no box,” he said.

Perhaps R.M.I.’s most influential client these days is Wal-Mart. Just to cart around goods that it sells in its stores, the company employs some sixty-eight hundred trucks, which annually consume at least a hundred and twenty-five million gallons of diesel fuels. In 2005, after consulting with Lovins, Wal-Mart announced plans to double its fleet’s fuel efficiency over the next ten years, from an average of six and a half miles per gallon to thirteen. Already, all of the company’s trucks have been outfitted with auxiliary power units so that the driver doesn’t have to keep the engine idling just to run the air-conditioner.

“In a room of ten people talking about why it can’t be done, Amory is the one working on the five ways to get there,” Andy Ruben, Wal-Mart’s vice-president for corporate strategy and sustainability, told me.

“I don’t do problems” is how Lovins once put it to me. “I do solutions.”

Lovins, who is fifty-nine, grew up in towns along the Eastern Seaboard; when he was a child, his family moved from Silver Springs, Maryland, to Elmsford, New York, and then from Montclair, New Jersey, to Amherst, Massachusetts. His father, who designed optical equipment, spent a lot of time in his home workshop, tinkering, and in this way Lovins, too, became interested in gadgets. While he was still in high school, he built a nuclear magnetic-resonance spectrometer in his basement, and discovered what he calls a “peculiar and still unexplained solid-state effect” having to do with cobalt. When he went off to Harvard, he helped pay his way by doing consulting work in experimental physics for, among others, the Lincoln Laboratory at M.I.T. Lovins enjoyed college – in addition to physics, he studied law, linguistics, and chemistry. But when, in his junior year, he was told he would have to complete a major he dropped out and moved to England. He attended Oxford until he was once again pushed toward a prescribed course of study, at which point he quit school again.

By this time – 1971 – Lovins had come under the influence of David Brower, the charismatic founder of Friends of the Earth, and he went to work for the organization in London. One of Britain’s largest mining companies, Rio Tinto, announced a plan to mine for copper in a national park in Wales, and at Brower’s urging Lovins spent a year writing a book about the park. The book, “Eryri, the Mountains of Longing,” was instrumental in blocking Rio Tinto’s plan. In the process of writing it, Lovins began to question the utility of his earlier research. (Today, Rio Tinto is a client of R.M.I.)

“It gradually occurred to me that the problems I was working on, whether they were tertiary structure of proteins or straight physics, were interesting but not very important,” he recalled. “Even understanding mitochondrial-membrane kinetics, which I briefly dabbled in, would be not nearly as important as solving basic problems of energy resources, environment, development, and security. Because it didn’t much matter how well we understood these other matters if we weren’t here.”

Much of Lovins’s early work centered on atomic energy. He wrote a series of papers arguing that the whole “atoms for peace” idea was misguided: there was no way to promote nuclear power without also promoting nuclear proliferation. (One of these papers spent two years under review by the U.S. government, which feared that Lovins had drawn the connection between processed fuel and bombmaking a little too clearly; the paper eventually appeared in Nature.) In his 1976 Foreign Affairs article, which was titled “Energy Strategy: The Road Not Taken?,” Lovins urged that the U.S. stop exporting nuclear technology and, simultaneously, that it phase out its own atomic-energy program. In the same piece, he warned that some of the alternatives to nuclear power were no less dangerous. At a time when the phrase “global warming” was barely in circulation, he observed:

The commitment to a long-term coal economy many times the scale of today’s makes the doubling of atmospheric carbon dioxide concentration early in the next century virtually unavoidable, with the prospect then or soon thereafter of substantial and perhaps irreversible changes in global climate. Only the exact date of such changes is in question.

Lovins’s opposition to both nuclear and coal-fired plants raised an obvious problem. How did he expect an energy-intensive economy like the U.S.’s to function? The way out of this bind, Lovins argued, was to reimagine it. People weren’t interested in energy for its own sake but, rather, for the benefits – hot showers, cold drinks, dry clothes – that it conferred. If Americans could get the same benefits using less energy, then they would, in effect, have found a new energy source. Meanwhile, instead of building large centralized power stations, they could gradually shift to localized sources of renewable power, like solar cells. Lovins labeled a future dominated by an ever greater number of ever larger power plants “the hard path”; the alternative he called “the soft path.”

“The hard path entails serious environmental risks, many of which are poorly understood and some of which have probably not yet been thought of,” he wrote. “The soft path…hedges our bets. Its environmental impacts are relatively small, tractable and reversible.” Several years later, perusing a report put out by the Colorado Public Utilities Commission, Lovins came upon a misprint: someone had typed an “n” for an “m” in the word “megawatt.” He coined another new term: “negawatt.” A negawatt is a watt of electricity that does not have to be generated because an energy-saving measure has obviated the need for it. By replacing a seventy-five-watt incandescent light bulb with a fourteen0watt compact fluorescent bulb, an individual can, for example, produce sixty-one megawatts. By replacing ten incandescent bulbs with ten compact fluorescents, the individual can generate six hundred and ten negawatts. Negawatts tend to produce more negawatts; for instance, a house lit with compact fluorescents requires less air-conditioning, since fluorescent bulbs emit a fraction of the heat of incandescents. The same principle can be applied to all forms of energy, including oil. Lovins likes to call the United States the “Saudi Arabia of nega-barrels.”

This past fall, Lovins came to Manhattan for a conference sponsored by former President Bill Clinton. The evening before the conference began, I went out to dinner with him at a Japanese restaurant in midtown. We were ushered into a room in the back. A cone-shaped light fixture hanging from the ceiling cast a pallid gleam onto the table. A few feet away, a row of recessed lights threw circles of brightness onto nothing in particular.

“This is what happens if your lighting is designed by electricians,” Lovins told me, glancing around. ”Who wants spots of light on the carpet?” He noted that all the bulbs were incandescents, and that the bulb hanging over the table was on a dimmer, which further reduced its already minimal efficiency. Lovins estimated that a better-designed system could cut the restaurant’s lighting costs by eighty per cent. “There’s upward of a hundred giant power plants to be saved by proper lighting systems,” he observed, before turning his attention to the sushi menu.

To spend time with Lovins is to see the world as one long string of bad decisions. Waste and profligacy are everywhere: in inefficient lights, heat-leaking windows, gas-guzzling trucks, poorly designed eateries. It’s not that people are stupid, exactly. It’s that their intelligence is limited. When they make decisions, they tend to worry only about their own self-interest, which is they see in such narrow terms that they miss the larger opportunities all around.

Take, for example, the electrical system of an average office building. “If we were to dig into the ceiling of most offices where the wiring is for the lighting, we’d probably find that the wire size was specced by the low-bid electrician to meet the National Electrical Code,” Lovins told me. “The code says you need wire so fat for so much current. Well, it turns out that wire-size code is meant to prevent fires. What would be economically optimal in terns if resistance losses would be wire twice as fat, which means four times as much copper. Now, the electrician isn’t going to pay your electric bills, right? If you had such an altruistic electrician that they were willing to put in four times as many pounds of copper to get you a one-year payback on your electric bills, they wouldn’t get the job, because they wouldn’t be the low-bid electrician anymore.”

The problem here is what’s know as a split incentive, but might better be called a mis-incentive. If the parties figured out how to divy up the savings, they could both make money, but, because of ingrained habits, or a lack of creativity, these savings are never realized.

“Let me give you a specific case – a two-hundred-thousand-square-foot curtain0wall office tower near Chicago,” Lovins said. “Chicago is cold in the winter and hot in the summer, and this was a very uncomfortable building all year round. In the winter, it had frost growing on the walls. The window seals were starting to fail, because they were twenty years old, so they were going to have to reglaze the whole glass curtain wall. Normally, you would put in the same glass that’s already there, which in this case was dark, double-bronze, heat-absorbing glass with a gray film. It let in nine per cent of the light, so the place was as gloomy as a cave. We designed a super-window that would let in nearly six times as much visible light but a tenth less unwanted heat. It cost an extra seventy-eight cents per square foot of glass. If you combined those super-windows with retrofits that bounced the daylight all the way through the floor plate and with very efficient lights and lighting controls and office equipment, you could cut the peak cooling load on the hottest afternoon more than fourfold. That meant that instead of just renovating the big old air-condition system you could replace it with one that’s four times smaller. And that would cost two hundred thousand bucks less, and that money could then pay for the better windows and the retrofitting of the lighting and other improvements. So you’d end up saving three-quarters of the energy at a slightly lower cost than the regular renovation – the payback time was minus five months. So we proposed that to the owner. They liked it, and we all thought it was going to be implemented. Surprise! It never happened. Why not? Because that particular building was controlled by a leasing agent whose incentive was deal flow. Whenever a floor got leased up, the agent would pocket a commission. And, not wanting to interrupt the commissions for a few months, the leasing agent vetoed the retrofit.

“It was a lovely lesson in how real such perverse incentives are – and how pervasive,” Lovins went on. “Each one is a showstopper, and each one is a business opportunity.”

The Clinton Global Initiative is part of the Renaissance Weekend – Sun Valley – Davos circuit, and it combines, freely, elements form the Council on Foreign Relations and the Vanity Fair Oscar party. (On my way to meet Lovins, I happened upon Richard Branson salaaming, “Wayne’s World” style, to Archbishop Desmond Tutu.) The day the conference began, Lovins slept in, missing speeches by Bill Clinton and Laura Bush, but showed up for a working lunch devoted to energy and climate change. He was wearing a black suit and carrying a duffelbag-size briefcase. At his table were an executive from Cisco, the head of a Norwegian philanthropy, and the chairman of a group called SmartTransportagion.org who told me that Lovins’s work had inspired him to form the organization. The lunch was served on plates made from organically grown bamboo, and the table linens had been woven from compostable hemp. While the fair-trade coffee was being served, Warren Buffett walked in. Lovins unzipped his case, which turned out to contain, in addition to a laptop, a small library of R.M.I.-produced books and papers. He picked out a three-hundred-paged book titled “Winning the Oil Endgame” and made a beeline for Buffett. When Buffett declined to take the volume – he asked that it be sent to him at his office – Lovins seemed disappointed. But he recovered almost immediately. “That’s smart of him,” he whispered to me. “He doesn’t take anything too heavy.”

After lunch, everyone switched tables. This time, Lovins ended up sitting with several executives from Ford; Purpendu Chatterjee, the head of a private equity firm; and William McDonough, one of the preeminent “green” architects in the United States. In the front of the room, executives from the Swiss Reinsurance Company and DuPont were holding a panel discussion on energy-saving companies with the former NARO commander General Wesley Clark. Lovins spent most of the discussion sending e-mails. One was to the Norwegian philanthropist he had just met. The philanthropist owned a cheese farm; Lovins attached a paper on energy-efficient dairy farming. When General Clark said something he disagreed with, Lovins sent him a long e-mail outlining why. During a brief break in the program, Lovins sought out Thomas Friedman, the Times columnist, and Rick Fedrizzi, the president of U.S. Green Building Council, to give them a PowerPoint on a school R.M.I. had redesigned in Brazil. According to Lovins, the redesign had not only saved money but also improved students’ test scores and, somewhat more mysteriously, their dental health. During another break, he presented the mayor of San Francisco, Gavin Newsom, with an inch-thick pile of articles. As Newsom took the articles, he laughingly alluded to an equally thick pile of reading material had handed several weeks earlier, in Davos.

“Amory is my hero,” Jose Maria Figueres, the former President of Coast Rica, told me. “He is just so much fun. I love the way he takes advantage of the opportunity to push his agenda in the most” – he paused for a moment – “wholesome way.”

After the formal program ended, Lovins stayed on to talked to Purnendu Chatterjee. Among many other things, Chatterjee’s firm holds a controlling interest in a refinery in India. Lovins told him that typically, in a refinery retrofit, R.M.I. had been able to cut energy use by more than forty per cent. “Wow!” Chatterjee exclaimed. He said that he was thinking of building a new refinery. Lovins licked his lips and handed Chatterjee a stack of literature.

That night, there was a huge gala for conference participants at the Museum of Modern Art. Lovins arrived with another copy of “Winning the Oil Endgame” under his arm. It’s not easy to eat a plateful of canapés while holding on to a three-hundred-page book, but somehow he managed. He chatted with the head of an Australian automotive company about vehicle efficiency; to an official of Habitat for Humanity about low-cost homes that can be made from bamboo; and to an executive from Coca-Cola (another R.M.I. client). At one point, I told Lovins that a man who happened to be standing hear us was one of New York’s largest real-estate owners, Lovins headed straight for him. He delivered his usual pitch about making money by saving energy. The man pointed out that as a landlord he didn’t benefit from gains in efficiency; his tenants did. Lovins advised him to restructure his leasing agreements so that both parties could share in the gains. The man took Lovins’s business card.

As the evening wore on, and most people fell to drinking and schmoozing with their friends, Lovins continued to work the room. When the dessert trays were being wheeled out, I lost track of him. By the time I caught up with him again, he had managed to give away his book.

“Winning the Oil Endgame” is a characteristic Lovinsian project – ostensibly hard-nosed and at the same time shamelessly utopian. The book’s forward is by the former Secretary of State George Shultz, who notes that “Amory Lovins loves to be a bull in a china closet – any body’s china closet,” and the epigraph is by Antoine de Sait-Exupery: “If you want to build a ship, don’t drum up the men to gather wood, divide the work and give orders. Instead, teach them to yearn for the vast and endless sea.” The book’s premise is a variation on the theme Lovins first laid out back in 1976, this time applied to petroleum. The U.S., he argues, can cut its oil imports to zero by 2040, eliminate oil use entirely by 2050, and make money in the process.

In December, Lovins traveled to Washington D.C., to give a talk on the book. I met him at the airport, and on the way into town we stopped at his hotel to drop off his suitcase. When Lovins opened the door to his room, he was met by a blast of hot air. The room had its own thermostat, which had been set to seventy-nine degrees. A lamp by the desk was burning cheerfully. Lovins peered under the shade. “It’s an incandescent,” he said, switching it off.

Lovins’s speech took place in a hotel not far from the Pentagon. The crowd that greeted him in the ballroom was an eclectic mix: representatives from organizations like the Northern Virginia Conservation Trust and the Post Carbon Institute were sitting next to officials from the Defense department and the Government Accountability Office. (The research for “Winning the Oil Endgame” was partly funded by the Office of the Secretary of Defense.)

Lovins began with a slide showing an Army tent on a patch of sand – presumably in Iraq or Afghanistan. The tent was completely uninsulated. In front of it stood a five-ton air-conditioning unit, and somewhere in the distance an oil-fired generator was producing the electricity to power the unit. The oil for the generator had had to be hauled a great distance, at great peril to those guarding it, and yet most of the energy was going, in Lovins’s words, into “air-conditioning the desert.”

From the desert, Lovins turned to the seas to tell one of his favorite stories, about whale hunting. “In 1850, the fifth-biggest industry in our country was whaling, and most of houses were lit by whale-oil lamps,” he said. “But as whales started to get shy or scarce and the price of whale oil drifted up, this started to elicit competition, particularly from coal-based oil and gas. “ By 1859, these competitors had seized five-sixth of the whale-oil-lighting market. “This was a real shock to the whalers. They never expected to run out of customers before they ran out of whales. But that’s what happened, and they were soon reduced to begging for subsidies on national-security grounds.

“Oil feels al little like this now,” Lovins continued. “We’ve spent over thirty years amassing a very powerful portfolio of new ways to save oil or substitute for oil, but no one had bothered to add it up. And when we did so we found it was enough to salve all the oil we use and more.”

The largest share of oil consumed in the U.S. – nearly seventy per cent – is eaten up by transportation. By Lovins’s reckoning, most of that is wasted. The power needed to propel a car is a function of its weight, so building a vehicle out of steel means using energy largely to move metal. Lovins proposes making cars instead out of ultra-light carbon composites. An ultra-light car with a Prius-style hybrid engine could – in theory, at least – get upwards of seventy miles per gallon. Lovins has been pushing an ultra-light vehicle of his own invention, which he calls a Hypercar, for the past fifteen years, and has created a company, named Fiberforge, to license the technology needed to manufacture the necessary parts. But so far no one has been willing to finance a prototype. (Lovins himself gets around in a hybrid Honda Insight, which sports the bumper sticker “I’d rather be driving a Hypercar.”)

According to Lovins, by switching to ultra-light vehicles (including airplanes) and implementing a variety of other “end-use efficiency” technologies the U.S. could eliminate half of its oil needs. It could eliminate another twenty per cent by substituting biofuels for oil, and the last thirty per cent by replacing oil with natural gas. (Saving enoughnatural gas to replace a third of the country’s oil could be easily accomplished, he maintains, by, among other things, reducing electricity consumption.) The cost of eliminating oil use entirely would, by his calculations, come to half of what by official forecasts, would be spent on purchasing it. Meanwhile, the U.S.’s CO2 emissions would drop by twenty-five per cent.

“We know this sort of thing works, because we’ve done it before,” Lovins assures the crowd in Washington. He gestured toward a graph of oil consumption that had been projected on to a screen behind him. “Look at how steeply oil use and imports fell the last time we paid attention, which was from 1977 to 1985. In those eight years, the economy grew twenty-seven per cent while oil use fell seventeen per cent.

“All this can be done with all the same economic growth and the same growth in driving, in flying, in huge houses, and so on, that’s in the government forecasts,” he continued. “No new invention and no changes in life style. And it could all be done without new taxes, mandates, subsidies, federal laws, or anything else either party doesn’t like or could mess up.” Lovins went on in this vein for nearly ninety minutes, ending witha a quote from Marshall McLuhan: “Only puny secrets need protection. Big discoveries are protected by public incredulity.”

Lovins’s talk had gone on so long that there wasn’t much time for Q. & A. The few questions asked – most of them comments, really – ranged from mildly skeptical to aggressively so. One man demanded to know why Lovins would not “accept the fact” that there had been many advances in nuclear-power safety. A second man stood up and said that as long as he could afford it he was going to continue to drive his Jeep, his Jaguar, and his Harley. He said that the only way he could see to move the U.S. off oil was to raise the price. Afterward, while Lovins was handing out more copies of “Winning the Oil Endgame,” I got to talking to David Goldstein, the president of the Electric Vehicle Association of Greater Washington. He said that he did not expect to see ultra-light cars on the road anytime soon.

“Amory doesn’t understand some of the practical realities of how the world works,” he told me. “I want to believe him, but…”

Lovins’s promise that apparently intractable problems – oil dependence, global warming, nuclear proliferation – can be profitably resolved is both the great appeal of his approach and its biggest liability. Much of what he recommends sounds just too good to be true, the econometric version of “Shed pounds by eating chocolate!”

John Holdren, the president of the American Association for the Advancement of Science, has known Lovins for more than thirty years and considers him a friend. He says that Lovins’s contention that a great deal more work could be wrung from the energy we consume is “absolutely unassailable.”

“Amory has been more energetic, more persistent, and more creative in thinking about ways to make this happen than anyone else,” he told me. “But Amory has always believed – seemed to believe – that free-market economics alone, rationally applied, will solve the problem. And I don’t believe that.” Holdren observed that current projections suggest that global energy consumption will reach eighteen-hundred exajoules by 2100. In order to hold atmospheric CO2 levels at a ”tolerable” level, the world will need to produce five times the amount of energy it now gets from fossil fuels, using sources that produce no carbon dioxide. The only conceivable way to achieve this, he said, is to make the use of fossil fuels much more costly. “We just aren’t going to do it unless there’s a price on carbon.”

Marty Hoffert, a professor emeritus of physics at New York University who has written extensively on energy demand and global warming, is also on cordial terms with Lovins. “I support virtually all of Amory’s calls for efficiency,” Hoffert told me. “It’s an important thing to have people thinking about efficiency. But I don’t think that’s going to get us there. If we do things more efficiently, people may just consume more.”

This hypothetical problem is not merely hypothetical. Since the mid-nineteen-seventies, the American economy has grown steadily more energy efficient. What’s called the economy’s “energy intensity” – the ration of B.T.U.s to G.D.P. – has been dropping by roughly one and a half per cent a year, for a total of nearly forty-six per cent over three decades. These savings have, however, been more than offset by people thinking up new ways to use energy, so that in the same period the country’s total energy consumption has risen by thirty-nine per cent and its CO2 emissions by roughly the same proportion.

Meanwhile, the example Lovins likes to point to – the drop in oil use in the early nineteen-eighties – is, at best, equivocal. As Lovins notes in his book, what made people “pay attention” to oil consumption was the 1973 Arab oil embargo and the second, even more severe 1979 oil shock. Part of the drop was due to structural shifts in the economy away from oil-intensive activities. Part of it was fuel substitution by individual consumers and industry, as homeowners and factories switched from oil to, for example, natural gas. The largest part of it was increased fuel efficiency in both automobiles and buildings, led by the creation of federal auto efficiency standards in 1975. And, finally, part of it was a change in consumer behavior as Americans bought smaller cars and turned down their thermostats. Thus what Lovins offers as a demonstration that federal regulations and new taxes are unnecessary could just as plausibly be seen as evidence of exactly the opposite.

Lovins knows all these arguments and is unmoved by them. “Sometimes after I five a talk, some folks get irked that I talk only about solutions and not about problems,” he told me. “Andy typically someone will get up and give a long riff about all the bad things happening and all the suffering in the universe, which is basically true. And the only way I’ve found to deal with that sincere and well-founded concern is to let the person run down after a while and then ask as gently as I can weather feeling that way makes them more effective.

“What I think people are most hungry for – and trying hardest to locate – is practical and profitable solutions. And that’s where I can make a distinctive contribution. It’s a very pragmatic approach.”

After his speech, Lovins still had, by his accounting, eight hours of work remaining on a report that was due to following day. I went with him to his hotel to ask a few last questions. This time, when he opened the door the room was freezing; by turning down the heat he had apparently turned on the air-conditioner. I asked Lovins how his plan to save the world through energy efficiency could accommodate the open-ended nature of human desire. If, as he claims, conservation is profitable, what was to stop the profits from going straight toward more consumption?

“It doesn’t automatically prevent that,” he said. But, he added, “you might plow the money back into more efficiency rather than more powerboats and helicopter skiing. After all, you don’t rewash your clean clothes in the cheaper–to-run washing machine, because your clothes are already clean. At some point, I think you get jaded by continuous trips to Bali.

“Your neighbors might point out that what you’re doing is increasingly antisocial,” he continued. “On a moral or spiritual level, at some point you may discover you’re not all that happy having more stuff or more travel. Trying to meet non-material needs by material means is stupid and futile. Every faith tradition that I know decries materialism.

“Markets are meant to be greedy, not fair. Efficient, not sufficient. They’re very good at short-term allocation of scarce resources, but that’s all they’re good at. They were never meant to tell you how much is enough or how to fulfill the higher purpose of a human being.”

It was getting late, and I was keeping Lovins from his report. As I prepared to leave, he recalled another line, this one from Wallace Stevens: “After the final no there comes a yes and on that yes the future world depends.”
