  • Exxon Shareholders demand climate action

    For instance, ExxonMobil competitors — including BP, ConocoPhillips, and Shell — are all members of the U.S. Climate Action Partnership, a coalition of leading corporations and environmental organizations calling on Congress to deliver concrete global warming emissions limits (see www.us-cap.org/).

     
    “The market is moving while management at ExxonMobil is standing still,” Hawkins said. “It’s time for them to take this challenge seriously.”
     

    The Natural Resources Defense Council is a national, nonprofit organization of scientists, lawyers and environmental specialists dedicated to protecting public health and the environment. Founded in 1970, NRDC has 1.2 million members and online activists, served from offices in New York, Washington, Chicago, Los Angeles, San Francisco and Beijing.
  • Liberal campaigns against nuclear

    The federal Liberal Member for the south-eastern New South Wales seat of Gilmore, Joanna Gash, has started a petition against her own Government on nuclear power.

    Despite the Federal Government’s commitment to investigate the viability of nuclear energy, Ms Gash has started a petition for people opposed to a nuclear power plant in Jervis Bay.

    Ms Gash says she would be equally open to starting a petition for people in favour of nuclear power in her electorate, but so far nobody is calling for that.

    "If I had people coming to me, like I’ve had people coming for the other side of the fence, then I would consider a petition as well," she said.

    "But at this stage I’ve had nobody approach me, so naturally I’m doing a petition against a nuclear power plant for the electorate of Gilmore because that’s the concern I and many people in the community have."

  • Al Gore back in Australia in September

    ACF Executive Director Don Henry said: “Climate change is the biggest crisis we face. Australians want to find out what they can do and what we as a nation should be doing. This new training session by Al Gore will inform and inspire many more people to take action.”

    One of the Climate Project volunteer presenters and general manager of MECU Limited Rowan Dowland said: “Being a climate change presenter has changed my life. I feel I am part of the solution and not the problem. People are surprised to learn they can help stop dangerous climate change and that those solutions can represent such significant opportunity for business.”

    To date, the 84 presenters from the inaugural The Climate Project – Australia training session have presented 693 presentations to at least 40,000 people.

    Once trained, presenters agree to deliver their version of Al Gore’s now famous slide show presentation 10 times over the period of one year.

    The Climate Project originated in Mr Gore’s home town of Nashville, Tennessee, where he has trained 1,000 presenters. In April, 2007 Mr Gore trained 170 people in the UK to deliver his presentation on global warming.

    The only way to make an application for the September 2007 Melbourne training session of The Climate Project – Australia is online. Apply at www.acfonline.org.au/climateproject . Applications will close 13 July 2007.

    The training session will be carbon neutral.

  • Trees can manage soil salinity

    Pinus radiata better prospect than Cypress: Prospects for establishing cypress on farms were low because of its slow growth rates (80-year rotation). Reasonable growth could be achieved for Pinus radiata, in areas of above 600 mm rainfall.

    Species with desired traits: Other species identified as having rapid establishment and growth, and end product use for a range of soil types and climates, based on many trials and demonstrations (>100 ha) across 10–15 years included: A. mearnsii, A. stenophylla, E. camaldulensis, E. occidentalis, E. sideroxylon and E. viminalis. Other prospective species include E. melliodora and C. cunninghamiana.

    Lots of know-how: Considerable knowledge was available on species and provenance suitability to different soil conditions, including salinity. Local species identified as suitable for timber production in the southern part of the region were E. albens, E. blakelyi, E. conica, E. melliodora, E. microcarpa, E. populnea and E. sideroxylon.

    Limited prospects for northern NSW: Prospects for integrated forestry were greatest in areas of above 600 mm rainfall, but reducing risk and uncertainty was critical to industry development. Market development, infrastructure and incentive payments were prerequisites to extensive adoption. As with northern NSW, current prospects were limited.

  • Adventures in the Smart Grid

    Posted by Patrick Mazza at 3:06 PM on 10 Jun 2007

    On August 14, 2003, an overheated transmission line in Ohio sagged into the power grid’s greatest natural enemy, a tree branch. The resulting power failure cascaded from the Midwest to Broadway in seconds. Power grid operators were quickly on the phones trying to grope through the grid equivalent of the fog of war, but it was too late. The biggest blackout in U.S. history was underway, leaving 50 million people without power.

    The event underscores a crucial fact. Of all major infrastructures, the power grid is the least automated by digital technology. Contrast the big box chain which keeps a constant inventory linking checkout stand to warehouse with the utility which must send its linemen into the field to hunt out downed power lines. Or set the control room operator balancing power plants and demands against the internet, constantly rerouting information flows. Modern digital systems rely on real-time data and automated responses, while the grid functions on delayed information and human decisions.

    The immediate implication is declining power reliability as demands on the grid grow. Columbia University grid researcher Roger Anderson notes that "since 1998, the frequency and magnitude of blackouts has increased at an alarming rate … If present trends continue a blackout enveloping half the continent is not out of the question."

    But the more serious long-term implication is that the grid cannot take on the tasks it needs to accomplish to reduce global warming pollution. Look on the grid of today as if it were the old computer network with a mainframe computer at the hub and terminals at the end of the spokes. The "mainframe" of the grid is the central power station. Transmitting power out the spokes to end users is a relatively simple management task compared to a system in which power generators are distributed throughout the network and power flows are many-way. Utility engineers typically resist distributed generation specifically because it makes their management task more complex. Most states have now enacted net metering laws which require utilities to interconnect small-scale distributed generators, but cap the total amount in the system to avoid destabilizing the grid.

    So far solar photovoltaic panels, small-scale wind-power generators, fuel cells, and other localized generators have not penetrated far enough into the market to raise much of a challenge. But consider the moment at which breakthroughs are achieved and distributed generation experiences an explosive takeoff, as a number of observers project for solar PV power. Then power distribution systems will have to be automated. In effect, an information internet backbone will automatically route and manage the complex power flows of the energy internet.

    Cogeneration is prospectively one of the largest distributed energy sources. Building and industrial heat could be recycled to generate electricity on-site. Interconnection to the grid can make the business case for a cogen unit, providing a market for surplus and a grid backup when the unit is down. But utilities discourage these kind of connections, again, because they pose complex management problems. Smart Grid systems will make cogen far more economically feasible.

    In transportation, improvements in battery technology are stirring new interest in electrified options, including plug-in hybrids and pure battery vehicles. Mass-scale electrified transport will require Smart Grid systems. One function will be to match charging times to clean power availability. For example, in many regions wind power tends to be generated at night. A Smart Grid can send real-time signals to plugged-in vehicles alerting them to charge when turbine blades are turning. Another Smart Grid function will be to manage vehicle-to-grid networks in which electrified fleets supply power to the grid as well as receive power from it. Making intermittent renewables into a 24-7 power source requires energy storage, and our cars which generally sit parked 22 hours a day are an ideal match. Smart systems will manage "V2G" networks.

    An energy systems revolution is upon us, and the Smart Grid is at its very center. In future installments I will drill down more into the capabilities and potentials of the Smart Grid, as well as the obstacles and challenges along the road there. Meanwhile, for those who want to read up, check out my paper, "Powering Up the Smart Grid" for one of the most complete overviews of the topic.

  • Coke pollutes Ganges while promising ‘clean rivers’

    This is not the first time environmental groups have criticized Coke’s operations in India.

    In 2003, in response to a growing campaign against Coca-Cola, the Central Pollution Control Board of India surveyed eight Coca-Cola bottling plants in the country and tested the sludge at all these facilities. The Board found all the sludge at all the Coca-Cola bottling plants it surveyed contained high levels of toxic heavy metals like lead, cadmium, and chromium. At the time, it ordered the Coca-Cola company to treat its sludge as industrial hazardous waste.

    Those toxic problems, coupled with allegations Coke has been complicit in the murders of union organizers at bottling plants in the South American nation of Colombia, have been increasingly troublesome to the Atlanta-based company.

    In the last six months, 25 universities from the United States, Canada, and the United Kingdom, including the University of Michigan, the University of Guelph in Canada, and the University of Manchester in England, have all taken actions to remove Coca-Cola from their campuses.

    On May 29, the president of Smith College in Massachusetts, Carol T. Christ, barred Coke from participating in the school’s upcoming soft drink bidding process. Coca-Cola’s seven-year contract with Smith College expires on August 31.

    "In light of Coca-Cola’s business practices in Colombia and India, Smith will preclude Coca-Cola from the list of approved bidders when we enter the contract renewal process later this summer," Christ wrote in a letter.

    Coke vehemently denies the charges.

    "The allegations that led to this decision are based on Internet rumor and myth, and have been proven false time and again," Coke spokesperson Diana Garza Ciarlante told New Dehli-based Indo-Asian News Service.

    "While our business relationship with Smith College is important, the integrity and reputation of our company is more important," she said.

    On Tuesday, the soft drink giant announced its own environmental plan, pledging to spend $20 million to conserve seven of the world’s most critical river basins.

    Right now, it takes 2.5 liters of water to make and bottle 1 liter of Coke, and 250 liters to grow the sugar cane in the mix.

    "We are focusing on water because this is where Coca-Cola can have a real and positive impact," Coca-Cola Chairman and CEO E. Neville Isdell told a gathering of environmental advocates.

    The pledge was announced at the annual meeting of the World Wildlife Fund (WWF) in Beijing. Over the life of a multiyear partnership with WWF, the company pledged to focus on "measurably conserving" China’s Yangtze, Southeast Asia’s Mekong, the Rio Grande/Rio Bravo of the southwest United States and Mexico, the rivers and streams of the southeastern United States, the water basins of the Mesoamerican Caribbean Reef, the East Africa basin of Lake Malawi, and Europe’s Danube River.

    "We call this ‘greenwashing,’" said Srivastava of the India Resource Center. "An attempt by the Coca-Cola company to manufacture a green image of itself that it clearly is not, as their practice in India shows."

    Coke’s announcement did not mention any measures to conserve water basins in India, a decision that did not surprise Srivastava.

    "The Coca-Cola company and WWF did not dare to include India in this initiative (because) the public in India is increasingly becoming aware of the Coca-Cola company’s disastrous relationship with water, and would have to see it for what it’s worth — a drop in the bucket," he told OneWorld.

    The deal also rubs U.S. critics of Coke the wrong way.

    "In itself it’s a good thing, but we see it as largely a tactic to divert attention from other areas," Patti Lynn of the watchdog group Corporate Accountability told OneWorld.

    "Coke is just trying to get some public relations points. They’re using this as a diversionary tactic," she added.

    Lynn and other U.S.-based consumer advocates are angry because of the foray that Coca-Cola has made into the bottled water market.

    From the 1970s to 2000, Corporate Accountability says, the annual volume of bottled water purchased and sold in the United States has increased by over 7,000 percent. Yet the bottled water industry operates with little or no regulation.

    "Tap water is better regulated, and often safer," said Lynn, adding that bottled water costs 3,000 percent more.

    Lynn pointed to a 1999 study by the National Resources Defense Council on bottled water sold in the United States, which found traces of arsenic, chloroform, and other impurities; chemicals that would be illegal if found in tap water.

    Coca-Cola spent $1.7 billion on advertising last year. In North America, Coca-Cola distributes three bottled water brands: Dasani, Dannon, and Evian.

    According to the Washington, DC-based Earth Policy Institute, consumers spend about $100 billion on bottled water each year. By comparison, experts estimate that just $15 billion per year, above and beyond what is already spent, could bring reliable and lasting access to safe drinking water to half a billion people worldwide — fully half of those who lack it.

    "The way that Coke, Pepsi, and Nestle have marketed bottled water has had the effect of undermining people’s confidence in tap water and contributed to a broad societal shift," Lynn said. "Instead of buying bottled water, we need to be investing in our shared, public water systems."
