  • “Carbon divestment is a shining example” The divestment campaign – which originated in the United States and is now making its way across the Atlantic – is one shining example of what is needed to curb greenhouse gas emissions. [The Guardian] (The author, Mary Robinson, served as president of Ireland from 1990 to 1997 and UN high commissioner for human rights from 1997 to 2002.)
  • “When baseload fossil fuel plants are no longer baseload” Times are changing, systems are becoming smarter and more flexible, and base load generation no longer reigns supreme in the way it once did. Most analysts suggest it is on an inevitable decline. [RenewEconomy]

Science and Technology:

  • Eco Marine Power of Japan says that its rigid sail technology for ships, known as EnergySail, has successfully concluded function testing. EnergySail is a rigid structure that can be used to convert both wind and light power into energy. [The Motorship]
  • US project developer American Vanadium has announced that the US DOE’s National Renewable Energy Laboratory would evaluate and demonstrate the CellCube vanadium redox flow energy storage system at its state-of-the-art testing facility. [Creamer Media’s Mining Weekly]
  • A consortium consisting of Topell Energy and three electricity companies successfully tested a torrefaction technology to produce high quality, light, dry and very energy-dense ‘biopellets’ from biomass. [Biomass Magazine]
  • Imperial College research says useful life of turbines may be longer than some people have asserted, countering claims machines need replacing after just 10 years. Wind turbines can remain productive for up to 25 years. [Business Green]


  • Saudi Arabia will spend $173 billion on energy projects between now and 2018. Saudi Arabia is investing heavily in renewable energy in a bid to curb domestic consumption of fossil fuels, which eats into oil export revenues. []
  • Used EV batteries will be reused for storing grid power in Japan. The  island of Hokkaido has announced a 60-MWh/15-MW redox flow battery storage project would be built by Sumitomo because of large amount of solar PV systems being installed. []
  • Abundance Generation has received another vote of confidence in its crowd-funding renewable investment model, after raising a record £214,000 in just four days towards its latest wind energy project. [Business Green]
  • The Australian today reports that the Renewable Energy Target will “likely” be weakened in the wake of Alcoa’s decision to close the electricity guzzling Point Henry aluminium smelter in Victoria. [Business Spectator]

  • Stanford University professor Mark Z Jacobson’s proposed roadmap t0 a 100% renewably-powered US has a lot of solar and hydro in it, but for the most part, it is full of windpower. Bio-mass is notably absent. [Motherboard]
  • Federal officials have announced the approval of two solar energy projects on public lands in California and Nevada. The plants are expected to supply 550 MW of renewable energy, enough to power about 170,000 homes. More than 700 jobs will be created. [CBS Local]
  • Gov. Andrew Cuomo has announced 18 projects that receive funding through the Renewable Heat NY program, to help install high-efficiency, low-emission wood-fired heating equipment, according to a recent article in Biomass Magazine. [EIN News]
