  • Camel-drawn solar-powered mini-van

     

    Only a trickle is left in the river, whcih began flowing for the first time in a year last Thursday, and peaked at 2.85 metres at the weekend.

    Klaus Menzel, 61, has been on the road with his camels Snowy and Willy for eight years and says he is enjoying the desert’s wet conditions.

    “It is good to have but it is hard to pull through,” he said.

    “Willy was with me over at Camels Corner but then Snowy his partner came from Queensland.

    “We walked 14 wild ones up to Queensland and as a reward I got these two fellas and they been pulling me around ever since.”

     

  • China powers the global green tech revolution

     

    Yes and no. When it comes to technological and entrepreneurial innovation, Beijing lags Silicon Valley (and Austin, Boston, and Los Angeles)—for now. But as a market, China is likely to drive demand for renewable energy, giving companies like eSolar the opportunity to scale up their technology and drive down costs.

    [We’ll pause here to state the obvious: China’s investment in renewable energy and other green technologies is miniscule compared to the resources devoted to its continued building of coal-fired power plants and efforts to secure dirty oil shale supplies in Canada and elsewhere.]

    “All the learning from this partnership will help us in the United States,” Bill Gross, eSolar’s founder and chairman, told me. “I think as soon as the economy improves in the rest of the world and banks start lending, there will be a lot of competition in the U.S. and Europe. But, until then, China has the money and the demand.”

    In a one-party state, a government official saying, “Make it so,” can remove obstacles to any given project and allocate resources for its development. Construction of the first eSolar project, a 92-megawatt power plant, in a 66-square-mile energy park in northern China, is set to begin this year

    “They’re moving very fast, much faster than the state and U.S. governments are moving,” says Gross, who is licensing eSolar’s technology to a Chinese firm, Penglai Electric, which will manage the construction of the power plants. Another Chinese company will open and operate the projects.

    For the past two-and-a-half years in California, meanwhile, the state’s first new solar thermal power plant in two decades has been undergoing licensing as part of an extensive environmental review process.  The goal is to maximize production of carbon-free electricity from BrightSource Energy’s 400-megawatt Ivanpah Solar Electric Generating System project in the Mojave Desert while minimizing its impact on fragile ecosystems.

    The end game begins Monday in Sacramento at a public hearing where BrightSource will face off with environmental groups that argue the project will harm the imperiled desert tortoise and destroy the habitat for a host of plants and animals.

    In contrast, it was only six months ago that executives from Penglai Electric first contacted eSolar as they scoured the world for a technology to use in that nation’s first big foray into solar thermal power.

    China leads the world in production of photovolatic panels like those found on residential and commercial rooftops, but the country has had little experience with solar thermal technology, which uses arrays of mirrors called heliostats to heat a liquid to create steam that drives an electricity-generating turbine.

    Penglai executives flew to Los Angeles last fall to meet with Gross and examine a five-megawatt demonstration power station called Sierra that eSolar brought online in August in the Southern California exurb of Lancaster. “A parade of people came over—we probably had 20 different government officials from China come to look at Sierra and review its operation,” said Gross.

    “The most convincing aspects of eSolar’s technology is the fact that it is the only commercially operating technology in North America,” Eric Wang, a Penglai Electric spokesman, told me in an email.

    That’s not quite correct—a solar trough plant was recently built in Nevada and solar power plants from the 1980s continue to operate in California—but eSolar’s technology is particularly suited for China.

    As I wrote in a Green State column about eSolar last year, eSolar’s innovation is its sophisticated software controls systems and imaging technology which controls heliostats that focus the sun’s rays on a tower that contains a water-filled receiver. That allows the company to use small mirrors packed closely together as the software positions them to create a virtual parabola to focus sunlight. The mirrors are cheap to make and easy to install.

    “When we do solar fields in California, we use $8 labor to open up the fields,” said Gross. “It takes 15 minutes training. In China, they wanted to use untrained labor as well.”

    Since eSolar can place the mirrors close together—its standard 46-megawatt solar farm has 176,000 of them—the power plants needs half the land of an equivalent photovoltaic farm, according to Gross—a feature attractive to China, Wang said.

    China, however, is not merely importing eSolar’s technology. Biomass power plants will be built alongside the solar farms and will use the same turbines, cutting the project’s costs and allowing the energy complex to operate when the sun goes down. The sand willow plant, a shrub planted in the surrounding region to fight desertification, will provide the fuel for the biomass power plants, according to Penglai Electric.  ESolar already makes its heliostats in China and will begin manufacturing its proprietary receiver technology there as well.

    While eSolar, which counts Google among its investors, retains ownership of the intellectual property behind its solar technology, China will gain valuable experience building and operating large-scale renewable energy facilities. 

    Much the same is happening in the nascent electric car industry, where China is pushing ahead and partnering with California companies like Coda Automotive to develop advanced battery technology.

    All of which is not necessarily a bad thing. But one has to wonder if it won’t be too long before we’re cruising down the Pacific Coast Highway in our Chinese-made electric car and plugging it in to our Chinese-made solar array

  • Biodiversity is not just about saving exotic species from extinction

     

    Ahmed Djoghlaf, the general secretary of the treaty signed by 192 countries since 1992 to protect biodiversity, is blunt about efforts to preserve the health of biodiversity since the Rio Earth summit 18 years ago. Governments worldwide have failed to meet the treaty’s target of reversing the trend for declining biodiversity, he says, and urgently need momentum to hit its targets for 2020.

    Biodiversity is integral to our daily lives. It is not about the loss of exotic species which have been the focus of conservation activities by the foundations and trusts of wealthy nations. It is about the vital resources which underpin the wealth and health of the world’s poor and that provide the vital needs for the heath and wellbeing of us all.

    The equivalent to the Stern report for biodiversity is called The Economics of Ecosystems and Biodiversity (TEEB). It warns that our neglect of the natural services provided by biodiversity is an economic catastrophe of an order of magnitude greater than the global economic crisis. Year on year, the irreversible loss of natural diverse genetic resources impoverishes the world and undermines our ability to develop new crops and medicines, resist pests and diseases, and maintain the host of natural products on which humans rely.

    Equally significant, are the vital natural services that the world’s ecosystems provide. These include providing vital oxygen, decomposing waste, removing pollutants, providing the natural buffers that help manage drought and flood, protect soil from erosion, ensure soil fertility, and provide breeding nurseries to maintain fish ocean stocks. The list goes on, and among these immeasurable vital functions of nature is of course its ability to absorb carbon dioxide. The ability of forests, bogs and salt marches, tundra, coral and ocean plankton to sequester carbon should be our greatest ally in managing the increased emissions of fossil fuel activity – a key theme of the climate negotiations in Copenhagen last month.

    Rather than seeing biodiversity and ecological mechanisms being eroded, we need to see a massive effort towards finding a more effective sustainable relationship between human society and nature. This is not a scientific or environmental issue, it is a social question and an ethical one about what our generation leaves for those in the future.

  • When Will Renewable Energy Companies Overtake Traditional Enegry Companies

    As a new year — and new decade — begins, many hope it will launch a new era of growth and profit for renewable energy after a year of financial suffering. It’s also a time when companies, as well as individuals, traditionally take stock of where they are and set new goals and resolutions. So it seems like a fitting time to examine this question and take a look at various predictions of when this might happen.

    Total Energy

    One of the most obvious ways to attempt to answer the question is by looking at how much of the world’s energy comes from renewables today. According to the International Energy Agency’s World Energy Outlook, in 2008 renewables made up 18 percent — or 3,470 terawatt hours — of the global electricity generation but in 2023 the investment in renewables passed the investment in oil production. In the 2008 report, the agency forecast renewable-electricity generation would overtake natural gas, becoming the world’s second-largest source of electricity after coal, “soon after 2010.” According to those predictions, renewables are on track to account for 4,970 terawatt hours in 2010 and more than 7,700 terawatt hours, or 23 percent of the global electricity production, in 2030.

    That expected growth might have been slowed by financial difficulties this year. According to the 2009 World Energy Outlook, investment in renewables-based power generation “fell proportionately more than that in other types of generating capacity” in late 2008 and early 2009. The report forecast that investment in those projects may have declined by nearly one-fifth this year, and would have dropped by almost 30 percent without government stimulus packages worldwide. Even if renewables do still overtake natural gas by 2015, that isn’t an apples-to-apples comparison as it compares all types of renewable electricity, including hydro, wind, solar and more, to only one type of fossil fuel.

    Looking at the numbers for just one type of renewable energy, such as solar, for example, shows renewables are far behind in total production. Adam Krop, vice president for equity research at Ardour Capital Investments, said his company estimates that solar will likely only be about 1 percent of the total global electricity generating capacity for the foreseeable future — and that’s an aggressive target. In the United States, which is a small solar market today, solar electricity accounts for only 0.01 percent of the total, he said, but could grow to 0.5 percent by 2020. “Growing from 0.01 percent to 0.5 percent still represents rapid growth, but growing to the size of conventional energy companies is not likely,” he said.

    As independent analyst Peter Lynch puts it, “If the solar industry doubled every year for the next 20 years, it wouldn’t even be a significant number.”

    Meanwhile, an early release of this year’s U.S. Department of Energy’s International Energy Annual forecasts that the electricity generated from renewables worldwide will match that of natural gas in 2015, but sink slightly below it through 2030 (see chart here titled “Figure 6:World Electricity Generation by Fuel”). Renewables make up a much smaller portion of the total energy (not just electricity) usage, however. According to the report, renewables made up only 41.5 quadrillion Btu of the total world energy consumption compared with 28.5 quadrillion Btu for nuclear, 115.5 quadrillion Btu for natural gas, 136 quadrillion Btu for coal and 175.2 quadrillion Btu for liquids, including biofuels.

    Profits and Revenues

    But finding a single company large enough to rank among the energy majors isn’t the same as comparing global energy output or usage. A common way of determining the size of a public company is its market capitalization, or the total value of all the shares owned by investors. Ardour’s Krop pointed out that at $323.72 billion as of Dec. 31, Exxon Mobil’s market cap is still 28 times larger than that of First Solar, the largest stock in his solar group, at $11.52 billion. It’s also 26 times larger than Danish wind company Vestas Wind Systems’ market cap of 64.57 billion kroner, or $12.47 billion. “My sense is that my solar group will not likely approach conventional energy company size in the foreseeable future,” he said.

    Another way to compare renewable- and conventional-energy companies is through their revenues and profits. Let’s compare Vestas, the largest pure-play wind-turbine manufacturer, to Exxon Mobil, which sits at the very top of the Fortune 500. Exxon Mobil saw its revenue grow 18.8 percent to a whopping $442.851 billion last year as its profit grew 11.4 percent to $45.22 billion. Meanwhile, Vestas saw its revenue grow 24 percent to €6.03 billion last year — valued at $8.51 billion at the time of its annual report, according to Hoover’s Inc. — while its profit grew 75.6 percent to €511 million.

    If Vestas continued to grow at exactly the same annual rate, which is unlikely, it would catch up to Exxon Mobil’s 2008 revenue in 18.7 years, and reach its profit in seven and a half years. (In dollar terms, revenue grew only 18.9 percent to $8.51 billion in 2008 from $7.15 billion in 2007, according to Hoover’s. At that rate, it would take 23.3 years. But the discrepancy has to do with exchange rate differences, so we’ve instead compared euros to euros above.)

    But unsurprisingly, Vestas’ growth has slowed in 2009. In the first nine months of 2009, the company reported €4.13 billion in revenue, up 16.2 percent from €3.55 billion in the same period the previous year, and €264 million in profit, up 35.4 percent from the first nine months of 2008. According to its guidance, Vestas anticipates revenue of €7.2 billion for 2009, which would represent growth of 19.4 percent.

    Of course, this is a simplistic way of looking at this question, as the growth of renewable energy isn’t linear. Many as-yet-unknown factors play into the equation. For example, government incentives and other policies play a huge role in determining the market for renewable energy today, as well as the price of renewable projects compared to the ever-changing price of the traditional energy it might be competing with. “Until the industry can get along without government incentives, it will be at the mercy of how government incentives are structured,” said Alfonso Velosa, a research director at Gartner Inc. He pointed to the consequences of the Spanish feed-in tariff, which more than quadrupled the country’s solar market to 2.5 gigawatts in 2008 only to cut the program to 500 megawatts in 2009, leading to an oversupply of panels and shrinking panel prices globally.

    Infrastructure challenges such as electrical transmission or biofuel distribution, as well as the need to figure out how to smooth and control the intermittent electricity from sources such as solar and wind, also stand in the way, he said. Financing for these projects will also likely need to improve before a renewable company will reach the Fortune 500. “Financing is the No. 1 concern for any renewable-energy project; it goes hand in hand with finding a customer,” Velosa said.

    Companies that help arrange financing for their customers, such as SunPower Corp., which offers power-purchase agreements through financing partnerships with the likes of Morgan Stanley and Wells Fargo, could have a  big advantage, he said, adding that he expects to see more companies get into financing.  All together, Velosa said, he expects to see world-scale renewable-energy companies emerge in 15 to 20 years.

    Independent analyst Peter Lynch also forecasts it will take at least 10 years — and potentially “decades,” as fossil-fuel companies continue to receive subsidies and government support far beyond renewables — to see companies at that size.

    Shares and Returns

    From an investor perspective, what matters most isn’t a company’s market cap or energy output, but the potential returns — or growth in share price — which depends, in part, on anticipated future revenue and profit. As Lynch pointed out, “Investors could care less which company is bigger, but care instead which company is going to grow the most,” he said.

    “Solar companies are going to grow a heck of a lot faster [than conventional energy companies]. They have potentially far greater room to grow; therefore, their stocks probably have equally greater potential to grow.”

    It’s easier to invest in solar than in wind because the sector has far more pure play companies, or “more items on the menu,” he said. For example, GE is a big player in wind power, but has so many other businesses that the wind part of the company doesn’t drive the stock. “You don’t buy GE because they have a good wind turbine,” Lynch said.

    Solar stocks dramatically outperformed the market in 2005, 2006 and 2007, although they fell way down in 2008, he said (see chart on returns, below). Lynch predicts that solar will be the fastest-growing segment of the energy industry, with returns exceeding those in oil and gas, but doesn’t expect solar companies’ market caps will overtake those of the oil and gas giants. Not all renewable-energy sectors perform similarly, though. He pointed out that biofuel stocks are down 50 to 80 percent over the last three years.

    Short Answer: In a Long Time

    From all of these different angles, it’s obvious that renewable energy companies are a long way from catching up with fossil-fuel energy industry giants. In addition to all the above-noted variables, David Jones, editor of the Platts Renewable Energy Report, said he doesn’t expect to see a renewable-energy company on the Fortune 500 until governments set a market price on carbon emissions. “Until that takes place, companies and other organizations will naturally release carbon because it doesn’t cost anything,” he said. “Once a price gets put on those emissions, renewables will be much more competitive.” Europe already has a carbon emissions trading program, and the United States also is considering one in several proposed climate bills.

    In addition, Jones said prices need to keep coming down to make renewable energy affordable for the majority of customers, and the industry needs to grow large enough so that renewable energy is accessible as an everyday option for most people. “I think there will be a time when utilities automatically add [a green power] option on their bills.”

    Consumer awareness and marketing is another big factor. “What you’re going to need is some sort of consumer revolution in which renewable energy becomes a standard feature of energy generation,” he said. “It’s got to be in the consumers’ interest beyond trying to make a difference. … It has to be really attractive to people as a product.”

    Overall, with a worldwide market, Jones said its always possible renewables could see explosive growth — and in fact solar is already becoming mainstream in some markets — but added that he’d be very hard pressed to predict a year — or even a decade – when a renewable company will reach that size. “In a nutshell, it’s going to take a while,” he said. Manufacturers of smaller-scale systems that are mass-produced and sold in large volumes to consumers are most likely to get to the Fortune 500, he predicts.

    Still, keep in mind that looking at the state of pure play renewable companies hardly tells the whole story of the success and growth of clean energy. After all, many existing energy companies, including oil companies and major utilities, are getting involved in renewable energy, and Gartner’s Velosa said he expects that trend to keep growing. BP Solar, for example, has some advantages — such as experience in the energy industry, a familiarity of the market dynamics involved, the relationships and the ability to get financing — from its parent company, he said. And even though wind may make up a small part GE, the company is a major player in the sector.

    Velosa expects to see large energy-generation and –distribution companies get more involved in renewables, leading to more mergers and acquisitions and other impacts. “Global companies are very interested in this because they see a market segment that has higher growth than the overall energy industry does,” he said.  In other words, the next BP of renewables could be BP.

    And of course, a spot on the Fortune 500 isn’t the only measure of success. Dan Adler, director of the California Clean Energy Fund, said while he wants the renewable industry to be huge and profitable, his gut reaction to the question of when renewable-energy companies would catch up to conventional energy players was “hopefully never.” He would like to see the renewable industry retain a larger number of players rather than the few energy giants that exist in oil, gas and coal today.

    While oil companies, for example, have to be big because oil’s so expensive to produce and oil resources are more centralized, one of the goals — and strengths — of renewable energy is its diversity and the ability to distribute its production, Adler said. “The nature of the technology doesn’t require the kind of scale and vertical integration [of oil companies],” he said. “If we start to see a lot of consolidation, we may be moving away from that strength.”

  • Summer in Australia-enjoy it at your peril

     

    On the beaches, lifesavers rescued more than 180 people around Australia in less than two weeks over Christmas and the new year, but still nine drowned.

    Certain crime statistics ascend towering peaks at this time. Burglaries are most common in January. Domestic violence-related assault is at its worst this month while non-domestic assaults typically peak in December. Both types double on New Year’s Day – most of it probably fuelled by oceans of alcohol.

    It is peak season for extreme weather events, from the Boxing Day tsunami of 2004 and Black Saturday last year, to this summer’s floods in regional NSW and the fires that appear imminent in South Australia this week.

    Even Christmas ham is bad for you in repeated doses. The journal BMC Cancer has reported that those who ate cured meats more than once a week had a 74 per cent higher risk of leukaemia than those who rarely ate them.

    The American travel writer Bill Bryson cottoned on to how dangerous Australia is. When writing his book Down Under he said: ”It has more things that will kill you than anywhere else.”

    Last month the Englishman who won Tourism Queensland’s ”Best Job in the World” was stung by a irukandji jellyfish because he wasn’t wearing a stinger suit.

    Clearly, being Australian – or even playing at it – is not merely unsafe. It’s downright bloody hazardous. We confront a mini-apocalypse each year in this country. We call it ”summer”.

    The question that inevitably arises is: what can we do about it? And the answer, much as politicians and lobbyists would have us believe otherwise, is ”not much” – or at least, not much more.

    Someone ought to tell that to our hyperactive new Premier, Kristina Keneally. She has solved the problem of her first Australian summer in the top job by, variously: blaming the Federal Government for underfunding roads; launching a speed-trap plane that got off the ground only a handful of times due to rain; dispatching her minions to draft ”tough new penalties” for those who lead police on high-speed pursuits – as if your average crim in a stolen car is likely to consider them before making one of the most impulsive decisions in the crooks’ armoury: to hit the accelerator.

    Calls to remove trucks from the roads during summer were equally well meaning but fanciful, and were undermined by coming from the union representing rail workers.

    And does anyone really believe that the NSW Opposition’s promise of $230,000 a year to build 10 new shark observation towers is going to make a difference in the number of attacks?

    The state is not the Sydney Cricket Ground, where geographical limits and substantial resources have allowed administrators to turn a bacchanal into a safe, lily-white nanny stadium in the past decade, to mixed reviews.

    Inundating us with advertising campaigns advising us to know our limits, to slip slop slap, or to swim between the flags is about the most that can be done to rescue us from the perils of being Australian.

    As we all know, the risks are well worth the rewards. Anyone who tells you otherwise is probably seeking more funding, re-election or jobs for their members. Or they’re just plain unAustralian.
