  • Bio-fules may be noxious weeds

    The Queensland-based Invasive Species Council has assessed weed risks posed by 18 biofuel crops currently proposed as solutions to cutting greenhouse emissions, wrote science and environment reporter Rosslyn Beeby in The Canberra Times (4/10/2007, p.11).

    Noxious weeds being considered: The Council warned cultivation of energy crops on a large scale would cause "grave environmental damage", deplete water resources and inflict high costs on agricultural productivity. The report, by best-selling Feral Future author Tim Low and conser­vationist Dr Carol Booth, said seven plants currently being considered as promising biofuel crops were already banned as noxious weeds in parts of Australia. Two biofuel species – giant reed and Spartina – being hailed as "miracle crops" were listed by the World Conservation Union among the world’s top 100 worst invasive weed species.

    Solving one problem by creating another: "Australia should not try to solve one environmental problem by cre­ating another. These plants have no proven value as biofuel crops but bad reputations as weeds," Low said. One of the highest risk biofuels – the drought-tolerant tropical succu­lent Jatropha – had been promoted as a crop that could be grown without irrigation on 20 million hectares of "marginal land" in Australia, but was closely related to bellyache bush, one of the worst farm weeds in northern Australia.

  • The Solar Farmer

    The irrigation works with a central pivot. These plots look like large green circles from the sky. But roads in the prairies create a checkerboard. The result is four unfarmed corners on each checker, which provide amazing space for harvesting the sun in another way: with solar panels.

    Kunugi, as well as five other farmers, recently each had a 10 kilowatt (kW) photovoltaic (PV) solar system installed on their property. In the summer months, most of the energy generated from these systems will go to the farmers pivot irrigation and in the winter, it will go to the pool of electricity in the grid.

    Jack Gilleland is another one of these farmers. He pays $8,000 a year to power his irrigation system and will see that number cut in half with his PV system. "The best part is I’ll save money by producing my own green power from the sun," he says.

    The project will save the farmers money for three main reasons. The first one is a grant from the U.S. Department of Agriculture managed by the local Resource Conservation & Development (RC&D). The second is a $4.50 buy down per watt from Xcel Energy, the local utility. The last part of the equation is a federal tax credit of up to 30% of the upfront costs for a business such as a farm.

    But money will only make a project work with the right people. The main driver was Jim Mietz from the San Luis Valley RC&D. While others talked about the possibility of such a project, Mietz went ahead and initiated it. He also received help from Ravi Malhotra who works with iCAST, a non-profit that partners with communities to bring appropriate technology to the people who need it.

    iCAST helped with the project design, development of the bid and managed the proposals to eventually pick the best bid, which ended up being Direct Water and Power Corporation. The company is installing the PV systems at the six farms, one of which includes Paul Newbenefit’s.

    Newbenefit is excited about the experience he, and the other farmers, will gain noting, "if we can learn something from it and encourage the solar industry, we’ll be happy… we are at a fantastic place for solar and we will [all] benefit."

    American producers like Kunugi, Gilleland and Newbenefit are joining the renewable energy revolution. The fact is they have good access to renewable resources like solar or wind energy. It’s usually just a question of ironing out the details and that’s where organizations like iCAST come in.

    This all leads to greater energy autonomy where we work with the forces of nature, farming the sun that just comes back every morning. As Kunugi says, "I just wish I could have gotten into it in a bigger way."

    Raphael Shay is the Outreach Coordinator at iCAST, where he bridges iCAST’s projects with the people who need them most. iCAST is a Denver, Colorado based organization that facilitates appropriate technology, business, and infrastructure development projects.

  • Depleted uranium enduring risk

    By Oct. 29, 70 per cent of U.S. air strikes were in support of the Northern Alliance armed forces, most guided by the U.S. Special Forces on the ground. The MQ-1 Predator drone with Hellfire missiles was operating over Taliban forces, directing air attacks and launching missiles.

    By Nov. 5 the number of individual air missions was up to 120 per day, adding F-16 and

    F-15 fighter-bombers out of U.S. bases in Kuwait.

    The turning point in the war to oust the Taliban government came on Nov. 6 at Mazar-e Sharif, a key city in the northern plains. Attack aircraft rained down hundreds of MK82 500-lb bombs. B-52 bombers used carpet bombing to kill thousands of Taliban forces. It was here that U.S. forces dropped the first BLU-82 Daisy Cutter bomb, each weighing 15,000 lbs, producing devastation over a 600-yard radius. All the weapons used by the U.S. air attack included depleted uranium shielding.

    Depleted uranium (DU) is produced during the uranium enrichment process. The U-235 used to produce fuel for reactors generating electricity is removed, leaving the U-238 isotope. The material is extremely dense and increases the penetration ability of weapons; it is used to coat shells and warheads on missiles and bombs. On impact, the shell, with its uranium and traces of americium and plutonium, vaporizes and becomes very tiny particles of radioactive dust. When it is inhaled it can stay in the body, emitting radiation.

    The DU used in U.S. weapons comes from the uranium mines in Saskatchewan.

    In the 1991 Gulf war, DU was delivered almost exclusively with shells from tanks and ammunition used by aircraft. It is used in all armour-piercing ordnance. In the wars in Bosnia in 1995 and Kosovo in 1999, NATO allies added DU missiles and bunker busting bombs. Thousands of DU bombs and missiles have been used by U.S. forces in the Afghan and Iraq wars. A typical bunker bomb contains 1.5 tonnes of depleted uranium.

    In August 2003 Scott Peterson of the Christian Science Monitor used a Geiger counter to test several sites in Baghdad near where bunker-buster bombs and missiles had fallen. He found radiation readings that were between 1,000 and 1,900 times higher than normal background radiation readings. DU weapons are still being extensively used in Iraq and Afghanistan.

    After the 1991 Gulf War, birth defects and leukemia rose dramatically in the areas around Basra where these weapons were used. By 2003, the U.S. Defense Department admitted that over 200,000 Gulf War veterans had filed for compensation for death, illness or disabilities.

    The veterans refer to this as "Gulf War Syndrome." In the first Gulf War, the U.S.-led coalition suffered 148 deaths.

    Since then 8,000 veterans of this war have experienced early death.

    In 1996 the U.N. General Assembly adopted a resolution declaring that DU weapons were illegal "weapons of mass destruction." In 2002, the U.N. Human Rights Convention passed a resolution urging a ban on the use of any DU weapons. We will have to wait to find out the impact of these weapons on the people of Afghanistan and the men and women in the U.S., Canadian and NATO armed forces.

  • Mungo’s slip reveals ALP’s Achilles heel

    Mungo’s defence of Garrett, as much as Garrett’s desertion of principle itself, proves that the Alternative Liberal Party is now a creature of the establishment. The ALP must, according to Mungo, compromise its principles to gain power. If that means selling workers down the drain, Uranium to warring states, or our hospitals, schools and water to international corporations, then so be it.

    When the Liberal Party self destructs after this election, Mungo and other apparatchiks of the establishment will find themselves facing a far more formidable opposition; a passionate and principled movement that is ready to govern on behalf of the people and the environment that supports us.

    The choice for the future is stark. We either vote for the establishment parties that will sacrifice us all on the altar of economic growth or for the emerging parties that recognise we must learn to live better to survive.

  • Largest windfarm proposed for Western NSW

    A company is seeking approval to build Australia’s largest wind farm, which would be able to power up to 400,000 homes, in the New South Wales outback.

    Epuron, a subsidiary of German renewable energy group Conergy AG, wants to place 500 turbines on up to five private properties at Silverton, near Broken Hill, in the state’s far west.

    Executive director Andrew Durran says the wind farm could produce more than half the renewable energy target proposed for the state.

    Mr Durran says it would satisfy almost 4.5 per cent of the state’s power demand.

    State legislation on renewable energy targets is due to be debated in the next session of Parliament but Mr Durran is concerned the Bill does not stipulate that projects must be state-based.

    "That’s why we’re announcing this today," he said. "It’s to prove that New South Wales has got more than enough capacity to deliver its targets.

    "NSW is the best state in Australia for wind farms – it has excellent wind resources, it has a very strong power-transmission network.

    "This one project can deliver more than half the renewable energy target proposed in NSW."

    The company says strong state legislation would give it the confidence to proceed.
