Concentration of CO2 in the Atmosphere

September 21 Green Energy News


  • “Errors and Emissions – Could Fighting Global Warming Be Cheap and Free?” Two reports both claim strong measures to limit carbon emissions would have hardly any negative effect on economic growth, and might even lead to faster growth. But will anyone believe the good news? [New York Times]

Science and Technology:

  • Last month was the warmest August since records began being kept in 1880, according to NOAA. They also projected out scenarios for the rest of the year making clear that 2014 is going to be one of the very hottest years on record — and possibly the hottest. [Energy Collective]
  • The Center for Biological Diversity has said the Earth is currently going through its sixth mass extinction of plants and animals. Now, researchers at the University of Georgia have concluded that species are going extinct 1,000 times faster than normal. [The Weather Channel]
  • Australian battery technology developer RedFlow says trials of its zinc-bromine “flow” batteries shows that the technology is “cost competitive” in large-scale applications on the electricity grid. [CleanTechnica]
  • The Germany-based Novatec Solar has commissioned a new solar plant that uses direct molten salt technology. The plant can operate at temperatures well above 500° C, resulting in a significant increase in power yield and an ability to act as baseload generators if required. [CleanTechnica]


  • The largest self-use solar rooftop power plant in the Philippines was launched yesterday at a shopping mall in Laguna. The 700-kW Central Mall Biñan solar rooftop project is part of the country’s efforts to promote renewable energy and reduce dependence on coal. [Philippine Star]
  • A march in London today to demand urgent action on climate change is one of 2,000 events taking place in 150 countries around the world ahead of a United Nations climate summit next week. Some 100,000 people are expected to get involved in New York City. [Daily Mail]
  • On the eve of the UN Climate Summit, Desmond Tutu argues that tactics used against firms who did business with South Africa must now be applied to fossil fuels to prevent human suffering. [The Guardian]
  • The world is running out of water resources. This threatens conventional electric supplies, as coal, gas, nuclear, and hydroelectric sources are all subject to limitations by the coming water shortage, because they all depend on water either for power or for cooling. [Motley Fool]


  • Consumers in 13 states and the District of Columbia could be overcharged $433 million in annual utility bill savings over the next three years, and $127 million annually after that point, because PJM is undercounting energy efficiency’s effectiveness in cutting power demand. [CleanTechnica]
  • After years of advocating for wind energy and the importance of the Renewable Portfolio Standard, Kansas Governor Brownback says he is in favor of repealing the RPS. His opponent in the election says the repeal is intended to eliminate competition for the Koch brothers industries. [hays Post]
