Concentration of CO2 in the Atmosphere

April 17 Green Energy News


  • “No, the IPCC climate report doesn’t call for a fracking boom” Interpretations of the report saying it endorses fracking, urging a “dash for gas” as a bridge fuel to put us on a path to a more renewable energy future are exaggerated, lack context, and are just plain wrong. [Grist]

Science and Technology:

  • Newly built wind and solar with natural-gas as a backup can make power a fifth cheaper than nuclear backed by gas, the study by consultant Prognos AG shows. It says excluding the backup generation, renewables produce power 50% cheaper than nuclear. []
  • The IPCC report is positive on renewables’ ability to deal with carbon emissions. It addresses nuclear power as a possible solution, but also underscores considerable barriers for it. The combination illustrates the conclusion that nuclear is largely irrelevant. []


  • When the wind blows and the sun shines in Germany, electricity prices in the country plummet. Natural gas peaker plants are not needed, as the peaks are erased and they cannot compete with renewables. But the grid still needs balancing resources like demand response. [Energy Collective]
  • Germany’s RWE expects profits to stabilise beyond 2014, albeit at a lower level. It will target customer-friendly products to offset a decline in traditional power generation. Renewable power and lower demand has made many of its fossil fuel plants redundant. [Business Spectator]
  • Australian households are driving the country towards a clean energy future by themselves, spending billions on generating their own electricity and providing nearly two-thirds of all investment in renewables in Australia in 2013, and virtually all of it in 2014. [RenewEconomy]
  • Turbines located in a sea-wall stretching across a Bristol Channel bay could provide power to over half a million homes while combating coastal erosion, preventing floods and regenerating the local economy, according to the company behind the idea. [Western Morning News]
  • The Australian Capitol Territory government is set to announce the next stage of its introduction of large clean energy projects with a reverse auction for 200 MW of wind-generated electricity. The goal is to have 90% renewable sources by 2020. [The Canberra Times]
  • GE’s Digital Energy is helping Scottish Power integrate renewable energy onto power grid. GE will provide series compensation capabilities to three facilities in southern Scotland, helping the utility meet and mitigate today’s highly complex and technical grid challenges. [PennEnergy]


  • President Obama will challenge companies Thursday to expand their use of solar power, part of his ongoing effort to leverage the power of his office to achieve goals that have been stymied by Congress. [Washington Post]
  • Private sector interest may be helping drive the wind sector forward. IKEA says the Hoopeston Wind facility outside of Chicago will provide 165% of the electricity needed for its entire US retail and distribution footprint. []
  • For the tenth consecutive year, Xcel Energy has been named the country’s top wind energy provider. As of 2013, Xcel Energy had 5,080 MW of wind energy on its systems, enough wind power to meet the energy needs of about 2.5 million homes. [AltEnergyMag]
  • Southern Maryland Electric Cooperative has entered into a power purchase agreement with an affiliate of juwi solar Inc. to develop, design and construct the 10.0-megawatt (MW) Rockfish Solar facility on 80 acres in Charles County, Maryland. [Southern Maryland News Net]
