Concentration of CO2 in the Atmosphere

November 5 Green Energy News

Science and Technology:

  • The cost estimates for solar PV used by the Intergovernmental Panel on Climate Change in its latest report fail to take into account most recent cost reductions for the technology, reports Helle Abelvik-Lawson, and exaggerate financing costs. The result is to understate the importance of PV in a low carbon future. [The Ecologist]
  • A new flow battery system from Imergy Power Systems  can use vanadium extracted from fly ash waste rather than more expensive purified vanadium. That helps keep the cost of the vanadium flow battery to just $300 per kWh, almost half the current industry standard. [Sustainablog]
  • Japan’s Eco Marine Power is developing a number of sustainable shipping technologies that harnesses both wind and solar power, and has been making steady progress towards a commercial system over the last few years. One example is a rigid sail capable of using both wind and solar energy to help power a vessel. [Ship & Bunker]
  • Clean technologies could generate more growth in innovation and the economy than fossil fuel based technologies, Imperial College researchers report. Clean technologies include smart devices, renewable energy such as wind power and green transportation including electric cars. [Imperial College London]


  • Five towns in New South Wales have raised their hands to become the first zero net energy town in the state – and indeed in Australia. Walcha, Manilla, Tenterfield, Uralla, and Bingara all made applications to become a signature town of the 21st Century and center of green innovation. [CleanTechnica]
  • Several of Egypt’s major cement producers have begun retrofitting their plants to run on energy from imported coal, beating high gas prices and energy shortages that have curbed industrial output this year. Supply from state-owned Egyptian Natural Gas Holding Company has been intermittent. [Reuters]
  • In Cornwall, the Lanhydrock Estates Company has applied for a solar farm to be constructed on two fields at Newtons Margate. If granted planning consent, the 12,000 modules will provide 3 MW of electricity for Tulip Ltd’s food production factory at Bodmin, with surplus going to the grid. []
  • In a growing grassroots movement, citizens of Berlin are banding together to try to buy back the electricity grid, in the hope of seeing more renewable energy used in the city. Berlin’s energy grid has 35,000 km of underground cable and more than 8,000 substations that feed electricity to more than 2 million customers. [Radio Australia]
  • The Australian government has cut almost half a billion dollars from research into carbon capture and storage – which the Intergovernmental Panel on Climate Change deems crucial for continued use of coal – despite the prime minister insisting coal is the “foundation of our prosperity”. [The Guardian]


  • According to the US Energy Information Administration (EIA), no new coal-fired plants came to service in the first 6 months of 2014, and only two small units are projected to come on line by the end of the year. The prospects for more coal-fired plants in the future look dismal for several reasons. [RenewEconomy]
  • In New Mexico, anger has spread over news that the country’s largest methane leak, near the Four Corners region, is three times larger than originally reported. The methane leak is attributed to gas production. For many New Mexicans, the dangerous human health and environmental hazard is a wake-up call. [Deming Headlight]
