  • Grist talks to Lovins

    question After all you’ve done to shift the energy debate, why do supply-side questions still dominate the discussion in Congress?

    answer Congress is a creature of constituencies, and the money and power of the constituencies are almost all on the supply side. There is not a powerful and organized constituency for efficient use, and there’s a very strong political (but not economic) constituency against distributed power, particularly renewables. So I would not pay too much attention to what Congress is doing. I’m not saying it doesn’t matter, but ultimately economic fundamentals govern what will happen — things that don’t make sense, that don’t make money, cannot attract investment capital.

    We see this now in the electricity business. A fifth of the world’s electricity and a quarter of the world’s new electricity comes from micropower — that is, combined heat and power (also called cogeneration) and distributed renewables. Micropower provides anywhere from a sixth to over half of all electricity in most of the industrial countries. This is not a minor activity anymore; it’s well over $100 billion a year in assets. And it’s essentially all private risk capital.

    So in 2005, micropower added 11 times as much capacity and four times as much output as nuclear worldwide, and not a single new nuclear project on the planet is funded by private risk capital. What does this tell you? I think it tells you that nuclear, and indeed other central power stations, have associated costs and financial risks that make them unattractive to private investors. Even when our government approved new subsidies on top of the old ones in August 2005 — roughly equal to the entire capital costs of the next-gen nuclear plants — Standard & Poor’s reaction in two reports was that it wouldn’t materially improve the builders’ credit ratings, because the risks private capital markets are concerned about are still there.

    So I think even such a massive intervention will give you about the same effect as defibrillating a corpse — it will jump but it will not revive.

    question Does the same critique apply to liquid coal?

    answer Yes. I was delighted when both the Chinese State Council and the U.S. Senate about a week apart canceled [liquid coal] programs.

    question But I’m sure you’re aware that the political push behind liquid coal is still very much pushing.

    answer Of course, including some people who should know better. It has fundamental problems in economics, carbon, and water, and bearing in mind that we can get the country completely off oil at an average cost of $15 a barrel, something in the $50s to $70s range doesn’t look viable. Those who invest in it, publicly or privately, will lose their shirts, and deservedly so.

    I think a good way to smoke out corporate socialists in free-marketeers’ clothing is to ask whether they agree that all ways to save or produce energy should be allowed to compete fairly at honest prices, regardless of which kind they are, what technology they use, where they are, how big they are, or who owns them. I can tell you who won’t be in favor of it: the incumbent monopolists, monopsonists, and oligarchs who don’t like competition and new market entrants. But whether they like it or not, competition happens. It’s particularly keen on the demand side.

    question Will Big Coal fall on its face?

    answer It’s already clearly happening in the global marketplace — although the U.S. lags a bit, having rather outmoded energy institutions and rules. Worldwide, less than half of new electrical services are coming from new central power plants. Over half are coming from micropower and negawatts, and that gap is rapidly widening. The revolution already happened — sorry if you missed it.

    question How might your notion of "brittle power" apply, not to developed countries but to countries that are developing in conditions in which resilience is at a premium? Iraq is the obvious example.

    answer Some of us have made three attempts at [bringing decentralized power to Iraq] and there’s a fourth now under discussion. The first three attempts, the third of which was backed by the Iraqi power minister, were vetoed by the U.S. political authorities on the grounds that they’d already given big contracts to Bechtel, Halliburton, et. al to rebuild the old centralized system, which of course the bad guys are knocking down faster than it can be put back up.

    question How could Iraq have played out differently?

    answer If you build an efficient, diverse, dispersed, renewable electricity system, major failures — whether by accident or malice — become impossible by design rather than inevitable by design, an attractive nuisance for terrorists and insurgents. There’s a pretty good correlation between neighborhoods with better electrical supply and those that are inhospitable to insurgents. This is well known in military circles. There’s still probably just time to do this in Afghanistan.

    Meanwhile, about a third of our army’s wartime fuel use is for generator sets, and nearly all of that electricity is used to air-condition tents in the desert, known as "space cooling by cooling outer space." We recently had a two-star Marine general commanding in western Iraq begging for efficiency and renewables to untether him from fuel convoys, so he could carry out his more important missions. This is a very teachable moment for the military. The costs, risks, and distractions of fuel convoys and power supplies in theater have focused a great deal of senior military attention on the need for not dragging around this fat fuel-logistics tail — therefore for making military equipment and operations several-fold more energy efficient.

    I’ve been suggesting that approach for many years. Besides its direct benefits for the military mission, it will drive technological refinements that then help transform the civilian car, truck, and plane industries. That has huge leverage, because the civilian economy uses 60-odd times more oil than the Pentagon does, even though the Pentagon is the world’s biggest single buyer of oil (and of renewable energy). Military energy efficiency is technologically a key to leading the country off oil, so nobody needs to fight over oil and we can have "negamissions" in the Gulf. Mission unnecessary. The military leadership really likes that idea.

    question Do you think that individual changes in behavior can or will have substantial effect on the energy situation?

    answer Yes, of course. People will vote with their wallets as well as their ballots, in a way that will affect the political system and even more the private sector, which is quite good at selling what you want and not selling what you don’t buy. The interplay between business and civil society is even more important than between business and government, and that is where I want to continue to focus most of my effort. I admire those who try to reform public policy, but I don’t spend much time doing that myself. In a tripolar world of business, civil society, and government, why would you want to focus on the least effective of that triad?

    question Reports out recently cast doubt on the environmental advantages of biofuels. Have you ever reconsidered your support for them?

    answer You’re treating biofuels as generic and I don’t think that’s appropriate. There are much smarter and much dumber approaches to biofuels, and biofuels do not need to have the problems you refer to.

    question But even cellulosic ethanol has come under criticism lately.

    answer Not from anyone knowledgeable that I’m aware of. Unless of course you need such large quantities of it, because you have such inefficient vehicles, that you start getting in land-use trouble.

    We suggest that U.S. mobility fuels could be provided without displacing any food crops. You could do it just with switchgrass and the like on conservation reserve land. Being a perennial, which can even be grown in polyculture, switchgrass and its relatives would hold the soil better because they’re much deeper rooted than the shallow-rooted annuals with which that erosion-prone land is often planted. And of course the perennials don’t need any cultivation or other inputs.

    Just a few weeks ago my colleagues and I led the redesign of a cellulosic ethanol plant — we were able to cut out very large fractions of its energy and capital need by designing it differently. There are other process innovations we’re aware of that would achieve similar results. I would not write off biofuels at all.

    Now, your broader point: Should it not be part of an integrated spectrum of efforts? Yes, of course. We can triple the efficiency of our cars and light trucks without compromised performance and with better safety, and we could also, if we want to get really conservative, stop subsidizing and mandating sprawl so we’d have less of it.

    The automotive revolution alone has a number of steps you could do in whatever order you’d like. In round numbers, if you take a really good hybrid and drive it properly, — not the way Consumer Reports says to — you roughly double its efficiency. If you make it ultra-light and ultra-low-drag, you roughly redouble its efficiency. Now you’re using a quarter the oil per mile you were before. If you then run it on, say, properly grown cellulosic E85, you quadruple its oil efficiency per mile again — you’re using a 16th the oil per mile that you started with. If you make it a good plug-in hybrid and have a good economic model to pay for the batteries — some of those are starting to emerge — then you at least double efficiency again. Now you’re down to about 3 percent the oil per mile you started with. And of course there are also renewable-electricity battery-electric cars. There are some sensible and profitable ways to do hydrogen, to displace the last bit of oil or biofuel, and there are other options like algal oils that are becoming very interesting. It’s a rather rich menu, and you don’t need all of it to get largely or completely off oil and make money on the deal.

    question Do you think private transportation will remain dominant for the foreseeable future or will there eventually be a shift to public transportation — high-speed rail, etc.?

    answer We can do a lot better in that regard, with policy and technical innovation, and there are many countries that already do. But with the settlement patterns we have in the United States, it’s difficult to make a large shift in a short time in that regard. It’s much easier to make the cars, trucks, and planes three times more efficient, and that has respective paybacks of two years, one year, and four or five years with present technology.

    question In your work, to what extent do you think about quality of life, or happiness, as opposed to providing the material goods we now consume more efficiently?

    answer A lot. It isn’t our main analytic focus, but of course every thoughtful citizen has to ask about the purposes of the economic process. As Donella Meadows reminded us, it is silly and futile to try to meet nonmaterial needs by material means. If we’re not careful in what we do, and how we decide, and in who decides, we can end up with outer wealth and inner poverty.

    question Thanks again, and congratulations on 25 years.

  • Europe burns as heatwave sets in

    "The alert remains high across the country," fire services spokesman Luca Cari told AFP earlier. "We have doubled the personnel rotations to ensure a stronger presence … and we have transferred personnel from the north of the country to the south to help us."

    In Romania authorities said the heatwave-related death toll rose to 33 with three more people succumbing on Tuesday.

    In the capital Bucharest where temperatures reached 37 degrees Celsius (99 Fahrenheit) more than 170 people fainted in the street. Ambulance services received a record of more than 1,200 calls over the past 24 hours, according to the Mediafax news agency.

    Power flickered on and off in Bucharest where air conditioners were working overtime.

    Some 30 people died in a heatwave last month in Romania.

    In Slovakia a lightning strike sparked a huge forest fire on Sunday that was still raging across about 10 hectares of the Slovensky Raj (Slovakian Paradise) national park in the east of the country.

    Meanwhile the mercury reached 46 degrees Celsius (115 F) in parts of Greece, where a dozen forest fires were burning and up to five people have died from heat-related causes since Monday.

    Authorities set up air-conditioned shelters in Athens and Greece’s second largest city Salonika, while fire forced the evacuation of a monastery, a village and a summer camp near the southern town of Aigion.

    Another fire on the Ionian island of Kefalonia threatened some nearby towns, firefighters said.

    Greeks were warned to stay indoors and help conserve electricity between 11:00 am and 3:00 pm to prevent power outages.

    "Until (Wednesday evening) when the heatwave passes, we ask for restraint," Interior Minister Prokopis Pavlopoulos said, adding: "We don’t need to have the air-conditioning on all day long."

    The heatwave caused a spike in smog pollution in Athens, with ozone levels above emergency limits in several districts, prompting the government to urge motorists to avoid the city centre. Ozone levels were not expected to improve on Thursday.

    The fire department said 99 blazes had broken out around Greece since Tuesday, added to hundreds of fires that have burned thousands of hectares of forest and agricultural land since a first heat wave last month.

    Temperatures in Greece were expected to drop slightly over the next two days.

    Hungary, where up to 500 people may have died last week from heat-related causes, enjoyed a significant drop in temperatures overnight with the welcome arrival of a cool front.

    Highs on Wednesday did not exceed 28 degrees Celsius (83 F), down from nearly 40 degrees Celsius (104 F) on Tuesday.

    A third degree heat alert — the highest ever applied in the country before last week — ended on Tuesday.

    On the western edge of Europe, even without a heatwave Portuguese firefighters are battling blazes near Abrantes, about 100 kilometres (60 miles) north of Lisbon, and in the Caldeirao mountains in the south.

  • Scientists wrong about glaciers

    By comparison, the study says, ice breaking off and melting from Greenland’s ice sheet contributes 28 per cent of the world’s ice to the oceans, and the Antarctic ice sheet a further 12 per cent.

    The accelerating contribution of glaciers and ice caps is due in part to rapid changes in the flow of tidewater glaciers that discharge icebergs directly into the ocean, the researchers say.

    When the glacier with its "toe in the water" thins, they says, a larger fraction of its weight is supported by water and it slides faster and sends more ice into the ocean.

    Alaska’s Columbia Glacier, which drops 3cukm into Prince William sound, had shrunk about 14.5km since 1980 and was expected to shrink the same amount in the next two decades, said geologist and co-author of the study Robert Anderson.

    The melting of the ice sheets of Greenland and the Antarctic is not expected to catch up with that of glaciers and ice caps untilthe end of the century, the study says.

    The researchers estimate the accelerated melting of glaciers and ice caps will add 10.2cm-24.1cm to the sea level rise globally by 2100. The figures do not include the expansion of the oceans as they get warmer, which could double the levels.

    A 30cm rise in the sea level causes a shoreline retreat of 30m or more, they say, and about 100million people live within about 1m of sea level.

  • NSW supports CO2 dumps

    Just dump it: The Government was using the best technology available in a bid to reduce emissions and research new ways to provide cleaner, greener energy. Clean coal research was identified as one of five key actions in the Government’s statement on innovation released in November last year. That was why the Government would contribute $22 million towards two pilot clean coal projects to reduce greenhouse emissions from power stations in New South Wales. This included a $20 million contribution to a geosequestration project and a freehold land grant valued at $1.9 million for the construction of an ultra clean coal demonstration plant at Cessnock.

    Coal pulling power continues: This commitment to clean coal research was part of the Government’s longer-term response to climate change. "We cannot have a climate change policy that does not take into account short-term reliance on fossil fuels," he said. "Coal is the world’s most abundant and widely distributed fossil fuel source. In New South Wales about 90 per cent of our electricity needs are met from coal-fired power stations. Burning coal without adding to global carbon dioxide levels is a major technological challenge that must be addressed".

    Tech options to store carbon: A number of technologies could be considered, including the strategy of advancing CO2 capture and storage, advanced pollution control devices, ultra clean coal as a turbine fuel, coal gasification and advanced coal-fired power stations including super critical generation, and oxy-firing technology.

    CO2 dump sites sought: The initial stage of the project would identify potential CO2 storage sites in New South Wales. The second stage would capture and permanently store CO2 inside the geological formations. The total cost of the geosequestration project would top the $60 million mark. The $20 million contribution from the State Government was to be matched by the coal industry’s Coal 21 Fund, a voluntary fund set up by the coal industry to address greenhouse gas emissions.

    Feds not cooperative enough: MacDonald said he had written to the Federal Minister for Resources, Ian McFarlane, asking for the Commonwealth to match the State Government and industry’s financial commitment to the project. But once again the Federal Government refused to provide a real financial commitment by offering only in-kind support to the project.

    "Ultra clean coal project": MacDonald said the NSW Government was also supporting the ultra clean coal project that would produce a high-purity, clean coal that can be burnt directly in gas turbines to generate electricity. Ultra clean coal-fired turbines potentially could reduce greenhouse gas emissions from the generator by 20 per cent to 30 per cent.

  • Brown coal companies back 60% targets

    One of the biggest greenhouse gas polluters has backed Federal Labor’s long-term climate change target by committing to cut its emissions to 60 per cent of 1990 levels by 2050, reported The Australian Financial Review (4/7/2007, p.11).

    Great expectations: TRUenergy, which runs victoria’s brown coal-burning Yallourn power station, said it would start upgrading plants, commissioning new-generation technology and using renewable energy.While Prime Minister John Howard has claimed that a Labor government would risk economic prosperity by cutting 2050 emissions by 60 per cent of 2000 levels, TRUchergy’s ambitions were greater than Labor’s because its target is relative to 1990 levels.

    National scheme needed:TRUenergy chief Richard McIndoe said it would cap carbon intensity, with cuts starting by 2010, and undertake not to build any traditional coal-fired power stations. But he said success depended on a natonal emissions trading scheme that set a carbon price.
