Concentration of CO2 in the Atmosphere

November 11 Green Energy News

Science and Technology:

  • Grid operators may be able to use buildings to help regulate grid frequency as they integrate more renewable energy sources. Variable-speed drives used to run heating and cooling systems can be rapidly modulated by grid operators to keep the frequency of electricity on the grid within necessary tolerances. [Energy Collective]
  • The Canadian public health department released its preliminary findings of a study on wind turbine noise and health, and an Australian court ruled on a challenge to a 105-MW wind farm based on wind turbine syndrome. In both cases, windpower was found not to have demonstrable adverse health effects. [Energy Matters]


  • The Kenya Electricity Generating Company decided to capitalize on their geothermal resources by adding 280 MW of geothermal energy to the national grid, and the power started feeding into the national grid in July. Kenya saved $100 million in the first three months of operation. [ESI Africa]
  • Denmark’s government plans to have the country completely off of fossil fuels by 2050, including cars. One problem with this is that energy production from wind and solar plants cost very little to run, so the more they appear, the less energy will cost. This means energy companies will struggle to make any profit. []
  • French renewable energy developer, Neoen announced that it is completing the financing for the project and starting construction of the developed facility located in the town of Cestas near Bordeaux. The facility will consist of several power plants with a combined power output of 300 MW. [PV Insider News and Analysis]
  • A report by the Overseas Development Institute and Oil Change International says governments around the world are funding high carbon energy sources at the expense of renewable energy projects. Australian taxpayers subsidize exploration by coal and energy companies by as much as $4 billion every year. [ABC Online]
  • Canadian Solar has finalized a deal to provide 4 MW of energy storage, to be used to support the electrical grid in Ontario, Canada. Ontario has a target to procure 50 MW of energy storage by the end of this year, of which 33.54 MW has already been procured by the Independent Electric System Operator. [PV-Tech Storage]
  • Senvion has signed a contract to supply turbines for the 150-MW Mesgi’g Ugju’s’n wind farm in Quebec. The MU project is owned and developed in a 50-50 partnership between the three Mi’gmaq First Nations of Quebec and Innergex Renewable Energy Inc. Senvion will deliver a cold-climate-version wind turbines. [North American Windpower]


  • Massachusetts is currently considering extending its net-metering qualification guidelines to include small hydroelectric projects over 60 kW in capacity, in addition to those under 60 kW. This would put hydroelectric on level ground with solar energy, wind energy, and anaerobic digestion systems in the state. [CleanTechnica]
  • Acer Americas is joining the growing ranks of US businesses meeting 100% of their electricity needs from renewable energy resources. The company has announced it is joining the EPA Green Power Partnership and has purchased enough green power to offset all of its carbon emissions from electricity in the US. [Triple Pundit]
  • A 5-MW solar array could be in place by next spring in the hills overlooking Lake Sonoma under a cooperative venture announced Monday between the US Army Corps of Engineers and the Dry Creek Band of Pomo Indians. The system would be the largest in Sonoma County, California. [Santa Rosa Press Democrat]
