    Humans did affect the atmosphere – even before industrialisation
    The Conversation
    Ruddiman’s hypothesis was criticised, but a few years later isotope measurements on methane trapped in polar ice cores indicated strong biomass burning – likely related to human activity – had increased atmospheric methane levels before the 16th century.

  • Solar islands floated as clean energy source for crowded continents

    Solar islands floated as clean energy source for crowded continents

    Global consultancy and certification firm DNV has unveiled designs for floating solar arrays that could rival offshore wind farms.

    The plans envisage a group of hexagonal artificial islands linked together and supporting 4,200 solar photovoltaic panels across an area the size of a football stadium. Multiple islands connected together could then make up a solar field of 50MW or more, producing enough electricity for 30,000 people.

    The concept, dubbed SUNdy, is made possible using 560W thin film solar panels, which are lighter and more flexible than traditional glass-based modules, allowing them to move with the waves on the sea’s surface.

    DNV says separating the solar arrays into prefabricated sections allows for large-scale manufacturing and streamlined assembly offshore, while the cable grid provides for maintenance access in the form of floating gangways. Below the surface, the island is then kept in shape by lengthy spread mooring.

    Bjørn Tore Markussen, chief operational officer at DNV KEMA Energy & Sustainability Asia, said SUNdy allows even the most densely populated countries to power their economies with renewable energy.

    “Many countries are turning to solar technology and renewable energy because of a need for alternative energy sources and environmental concerns,” he said.

    “We firmly believe the SUNdy floating solar field concept offers sound and sustainable development prospects, particularly in Asia and the congested coastal megacities where there’s limited opportunity for rooftop solar power and urban areas which command premium prices for large-scale mounted solar production.”

  • Light rail may determine who governs ACT

    Light rail may determine who governs ACT

    Updated 54 minutes ago

    The sole Greens politician in the ACT has hinted that light rail could be a pivotal issue when he comes to decide who to back to form government.

    Greens MLA Shane Rattenbury holds the balance of power in the ACT, after the two major parties ran a dead heat and won eight seats each in the election.

    The vote count was only finalised on Saturday and just 41 votes across the Territory separate the Liberal and Labor parties on primary vote.

    Serious discussions have begun between the party leaders and Mr Rattenbury to decide who will govern for the next four years.

    “Clearly a big responsibility has been placed on my shoulders,” Mr Rattenbury said.

    “But I’m not alone; the Greens membership is very heavily involved.”

    Mr Rattenbury says he wants to make a decision by Tuesday, which is when the Legislative Assembly is next due to sit.

    Federal Greens Leader Christine Milne says she is not advising Mr Rattenbury about which party he should help form government.

    “No, I’m not advising Shane about which party, I’m certainly talking to him and the ACT Greens about balance of power, about thinking about long-term outcomes in the best interests of the ACT, but he’s been taking advice from the ACT membership over the weekend,” she said.

    The Liberal Party says it deserves Mr Rattenbury’s support because it secured a 7 per cent swing across the ACT.

    “We are ready to govern,” said Liberal leader Zed Seselja.

    The Labor party governed with a minority in the last Assembly with Greens support.

    Light rail priority

    Labor also has the edge when it comes to its policy on light rail, which Mr Rattenbury suggests is a priority for the Greens.

    Greens members held a meeting on Sunday to decide on their priorities and discuss strategy with their sole representative in the Assembly.

    “They want to see good government in the ACT over the next four years to see us become a fair and sustainable city,” Mr Rattenbury said.

    “So things like light rail were high on the list of things members were interested in.”

    During the election campaign, Labor committed to building a light rail route between Gungahlin and Civic.

    It is part of a larger plan to build a citywide light rail network in partnership with the private sector, at a cost of $614 million.

    The Canberra Liberals have expressed concern over the cost of light rail.

    Mr Rattenbury said better public transport and cleaning up Canberra’s system of lakes are also priorities for Greens members.

    But Mr Rattenbury said he has been listening to viewpoints outside Greens circles as well.

    “I’ve had a lot more followers on Twitter suddenly in the last 24 hours and a lot of people expressing their views that way,” he said.

    “It’s great. It’s something I really like about Canberra in that you see people in the street and they’ll come up and have a chat and also on Twitter and Facebook people have really got a chase to put their own views.

    “I read all of that stuff – people have made a lot of good points and I value that.”

    Mr Rattenbury said while not everyone will agree with his decision on who to support to form government, he guarantees that the people of the ACT will experience stable government whatever the outcome.

    POWER users paid for a $40 million substation as part of $1 billion spent on gold-plating electricity infrastructure – and it’s not even hooked up to the grid.

    State-owned energy company Ausgrid spent the cash in breach of national electricity guidelines, with the costs passed on to consumers as higher network charges on their quarterly power bills.

    The company is planning to spend another $1 billion on pointless upgrades to poles and wires over the next two years, potentially adding a further $502 to the annual family power bill, according to the national regulator.

    A report commissioned by the Australian Energy Market Commission into recent electricity price hikes revealed that Ausgrid had “overspent” $1 billion on Sydney‘s power distribution network between 2005 and 2009.

    As one example of the so called “gold plating” pushing up power prices, it was revealed $40 million was spent on a needless substation built on the outskirts of Newcastle which would not be needed for another decade, and which a Senate inquiry has been told was not even connected to the power grid. Another, at a cost of $25 million, was built in Warringah and would not be “cost effective” for at least five years.

    Ausgrid, which owns and operates the power distribution network for Sydney, the Central Coast and the Hunter, also overspent $83 million on IT services and had paid almost $100 million for land in the Sydney CBD.

    “Ausgrid overspent on capex by approximately $925 million compared to the benchmark expenditures set by the regulators,” the report by independent auditors Parson Brinckerhoff revealed.

    A second report by the the Australian Energy Market Operator also revealed that Ausgrid was set to spend another $1 billion in 2013-2015 on network improvements that were not needed.

    The AEMO said that if the government cancelled the spending planned for next year, it would save $50 immediately for families struggling to pay their bills and up to $502 in annual savings by 2015.

    Both reports have been provided to a federal committee set up by Prime Minister Julia Gillard to investigate the reasons for power price rises in NSW.

    “The committee has heard evidence of gold plating by state-owned network businesses and consumers have been paying for this through their electricity bills,” committee chair Senator Matt Thistlethwaite said.

    “The states have failed to tackle this issue so the committee is considering measures to eliminate over-investment by network businesses and reduce pressure on household bills.”

    The AEMO has called for a more flexible cost-benefit approach to future planning for the electricity network.
