Concentration of CO2 in the Atmosphere

December 9 Green Energy News

Science and Technology:

  • In contrast to the whizz bang high-tech stuff, constructed wetlands are just that: engineered swamps where naturally occurring microorganisms digest the organic material in municipal wastewater, pulling out harmful substances as well as cutting down on the nutrient load. [CleanTechnica]
  • Ocean acidification is a big problem for many marine life forms, particularly shellfish and animals that depend on these creatures. That means it’s a big problem for us. The ocean, after all, is a vital food source for over 1 billion people depend on it every day for their protein. [Energy Collective]


  • Dong Energy, which claims to be the world’s biggest wind farm developer, says it is very upbeat on new investment in the North Sea. This comes days after the UK Government announced a better than expected subsidy regime for large offshore wind farms. [Greenwise Business]
  • Plans to give UK communities a greater say over wind turbine proposals are deeply flawed and will make smaller renewable energy schemes prohibitively expensive, according to Bristol-based consultancy Sanderson Weatherall, which advises  on renewable energy schemes. [North Somerset Business Leader]
  • The Indonesian-Swedish Initiative for Sustainable Energy Solutions will be working to assist the Indonesian government in developing its renewable energy policy, including reducing the damage to tropical forests caused by excessive development of oil palm plantations. [Jakarta Post]
  • Britain’s coal-fired power producer Drax opened its coal-to-biomass conversion plant as part of a £700 million project to clean up emissions from the country’s biggest coal power station. The plant will have three of the six generating units converted to burn biomass in place of coal. [Interactive Investor]
  • General Electric, the biggest maker of wind turbines in the US, says it will be making an investment of over $5 billion in building a 3,000 MW wind power plant in Turkey. The wind farm will more than double Turkey’s installed wind capacity. [Green Prophet]
  • French group Areva has signed a cooperation deal with China General Nuclear Power Corporation to work on offshore wind projects in both China and Europe. The effort will look for other opportunities including solar power, biomass, and storage technology. [Recharge]


  • At least 29 major companies operating in the US factored a price on carbon into their long-term business planning. And in 2010, the Obama Administration released the government’s estimates for that same price, to be used as a factor in rulemaking decisions by federal agencies. [CleanTechnica]
  • U.S. Rep. Annie Kuster, D-NH, is co-sponsoring legislation to create a national Renewable Electricity Standard. Kuster wants to require utility companies to produce at least 25% of their power from renewable energy sources like wind, solar and biomass by 2025. []
