Concentration of CO2 in the Atmosphere

December 3 Green Energy News


  • “City-owned Texas utility already serves 40% renewable energy” Is having local control of a utility the key to ramping up renewable energy? Communities can be inspired by examples like Denton, TX, whose utility already gets 40% of its power from renewable energy. [RenewEconomy]

Science and Technology:

  • Climate change is destroying coffee farms, putting farmers out of business. The cool mountains where coffee grows are getting warmer, and in places like Costa Rica, farms lower down on the mountain are producing less and less coffee. [Energy Collective]
  • Hitachi Ltd. unveiled an energy-storage system that the company said will support wind and solar power and allow users to sell electricity into deregulated markets such as California. Testing the product in North America will begin in the first three months of 2014. []


  • Japanese opponents of nuclear restarts are putting their faith in power saving and renewables. Eventually solar power could conservatively supply more than 10,000 MW of electricity in Japan, equivalent to the output of 10 nuclear reactors. [Financial Times]
  • Dublin-based renewable energy group, Gaelectric, announced that it has been funded €90 million to develop and expand its wind and energy storage business in Ireland, the United States and the UK. [Renewable Energy Focus]
  • The potential for many thousands of battery systems to act as a grid stabilizer has been highlighted at a renewable energy storage conference in Berlin. The distributed storage solution has been called cost-effective, as it mobilizes investment from private households. [Greentech Media]
  • New nuclear would not play a role in an independent Scotland, according to a white paper published by the Scottish government in November. The government is opposed to building new nuclear power stations in Scotland and will phase out existing stations. [Nuclear Engineering]


  • Two new reports from the DOE’s National Renewable Energy Laboratory say financing, permitting, installation labor, and other “soft costs” make up 64% of the total price of residential solar power systems. [Denver Business Journal]
  • PPL Generation has completed a 125 MW powerhouse at a hydroelectric plant in south-central Pennsylvania, increasing the plant’s capacity from about 108 MW to more than 230 MW. It also improves fish passage over the century-old dam along the Susquehanna River. [reNews]
  • Geostellar, a startup backed by power producer NRG Energy Inc, is seeking to become the Expedia or Orbitz of the solar industry — a one-stop shop where consumers can go from comparing leasing and buying solar panels to ultimately signing up to install a system. [Huffington Post]
  • California public power and water company Imperial Irrigation District proposed to expand its Southern California transmission system to boost the amount of renewable energy it can export to the rest of the state and to the U.S. Southwest. [Reuters]
