  • “Could a 500-house community go off-grid?” The shift away from a centralised to stand-alone community power solutions could be “quick and dramatic”, with most Australian regional towns able to function economically off-grid as soon early as 2020. [RenewEconomy]

Science and Technology:

  • A study published in the journal Energy & Environmental Science concluded it takes more work to make combinations of solar power and storage sustainable than it takes to do the same with combinations of wind power and storage. [RedOrbit]


  • The costs of achieving a more ambitious EU climate target are estimated to be moderate, according to a new report. Greenhouse-gas emissions reduction of 40% by 2030 would be likely to cost less than an additional 0.7% of economic activity. []
  • The UK’s energy regulator, Ofgem, has warned that the capacity margin, the amount of excess supply above peak demand, may drop below the 2% level in 2015, the lowest level in Western Europe. [PennEnergy]


  • First Solar Inc., of Tempe, Arizona, has begun construction of its 250 MW-AC Moapa Southern Paiute Solar Project. The project is located on the Moapa River Indian Reservation in the U.S. state of Nevada. []
  • Plans for a controversial cogeneration plant in Newark, Delaware have been approved by local authorities, despite protests. The 279 MW gas-fired plant will provide power and up to 200,000 kg of steam for heat at the University of Delaware. [Cogeneration & On-Site Power Production Magazine]
  • A report from the  NRDC shows that energy efficiency measures would produce dramatic carbon emission reductions, and that increasing renewable energy system deployment (wind and solar) would make an even bigger impact. []
  • Solar energy development in the Lincoln area got a big boost when the Lincoln Electric System Administrative Board approved a new renewable energy rate and incentive program. The program improves incentives for net metered solar systems. [Lincoln Journal Star]
  • The California Independent System Operator’s board of governors approved Thursday 30 transmission projects costing about $1.83 billion through the grid operator’s 2013-2014 transmission plan, an ISO spokesman said Friday. [Platts]
  • Wisconsin electric cooperatives Vernon Electric Cooperative and Dairyland Power Cooperative are setting the stage for increased community-owned solar, in partnership with the Clean Energy Collective. [Fierce Energy]
  • American Capital Energy kicked off construction of nine solar projects totalling 22 MW in Massachusetts. The portfolio in Cape Cod and Martha’s Vineyard includes 19.5 MW located on capped landfills. [reNews]
  • Sempra US Gas & Power and Consolidated Edison Development have announced they will partner on a 360 MW solar portfolio, each taking a 50% stake in the 250 MW Copper Mountain 3 project near Las Vegas along with other projects. [PV-Tech]
