Concentration of CO2 in the Atmosphere

September 17 Green Energy News

Science and Technology:

  • For renewables power sources, nearly all energy inputs are original production and mitigating the waste from that production. More energy is produced than the fossil fuels used. Wind is the most efficient fuel for electricity, creating 1164% of its original energy inputs. [Wall Street Journal]
  • MIT professor Fikile Brushett is working on taking the power generated by wind and solar, chemically lashing it to molecules derived from flora and fauna, and storing it in liquids until it’s needed to electrify our homes. The process may reduce costs of redox flow batteries. [PennEnergy]
  • A recent study by GE and NREL shows that the entire eastern US grid could achieve a dramatic increase in wind penetration without suffering any major destabilizing effects, without threatening electric reliability, and without installing any costly energy storage. [Scientific American]
  • Scientists at the University of Glasgow found a new way to make hydrogen that is 30 times faster than the state-of-the-art method, offering a solution to some common problems with generating electricity from renewable sources such as solar, wind, or wave energy. [Nature World News]

World:

  • Australia’s coal industry is in a flap after an announcement from the Chinese government it would ban the import of certain types of coal. According to the Wall Street Journal, the directive is primarily aimed at low-grade coal mainly coming from Indonesia and Australia. [Energy Matters]
  • The Kosh-Agach solar PV pilot power plant in the Altai region of Russia is now online. The 5 MW project is apparently the largest solar power plant to be installed in Russia to-date, and is serving as the prototype for a further four more such projects in the region. [CleanTechnica]
  • Germany switched on Europe’s largest commercial battery plant on Tuesday, an installation powered by 25,600 lithium-ion batteries that will help stabilise the region’s growing supply of renewable energy. The €6 million plant is the size of a school gymnasium and stores 5 MWh. [Economic Times]
  • New Delhi is going through a rooftop revolution because of a freshly-minted regulation by the power watchdog, the Delhi Electricity Regulatory Commission, which permits enterprises and residents to not only generate their own solar energy but also sell it to the grid. [Khaleej Times]
  • Over the past 17 years, the German village of Wildpoldsried has invested in renewable energy projects that include 4,983 kW of photovoltaics, five biogas facilities, 11 wind turbines and a hydropower system. Now it produces 500% of the energy it needs and sells the excess. [Inhabitat]

US:

  • The Vermont Yankee nuclear power plant has begun a gradual reduction of the electricity it generates that will end with the plant shutting down in December. The coast-down period will end the plant’s operating cycle as the nuclear fuel in the reactor is depleted. [WAMC]
  • A heat wave that set year-to-date records for California statewide power use on Monday and Tuesday was thwarted by electricity infrastructure that has been upgraded in recent years and increased power from renewable energy sources. Over 10% of demand was met by solar power. [Press-Enterprise]
  • The EPA announced it is extending the Clean Power Plan’s public comment period 45 days, making the new deadline December 1.The head of the EPA office writing the new rule said she still expects to meet the June deadline for making revisions to the rule based on the comments. [Journal and Courier]
  • In the Vermont, the Green Mountain State, sunflowers are an emerging source of renewable energy. Sunflowers are grown on several farms and then harvested for their oilseeds which are then converted to biodiesel and livestock feed. [Examiner.com]
