Concentration of CO2 in the Atmosphere

December 27 Green Energy News

Headline News:

  • In many ways, the German energy policies are a resounding success: the country sparked the modern solar industry, half of all renewables are locally owned, and traditional utilities are divesting themselves of centralized powerplants to work with distributed generation. But coal still supplies most of the power. [Energy Collective]
  • The year of the Horse saw the Philippine renewable energy subsector gallop to many milestones while other subsectors lagged behind or ran in circles.Solar power made the most strides, but wind developers also flexed their muscles, and run-of-river hydro and biomass are taking a steady pace. []
  • ERCOT, which manages 90% of Texas’ electric grid, took another look at the impact of seven EPA clean air safeguards on the electric grid. They now say that once power companies comply with EPA’s other clean air protections, the proposed Clean Power Plan’s requirements could be met by closing a single coal-fired plant.

  • Superficially, it makes sense for investors to shy away from putting money into renewable energy, as fossil fuels get cheaper. But theimpact of the price of oil on the renewables sector is more complex. Falling prices could actually prove helpful to the likes of Tesla Motor and SolarCity by affecting one important variable: the Federal Reserve. [Wall Street Journal]
  • One misperception in San Francisco is that, due to the fog, the solar power potential for the city is not good, but this is not true. San Francisco’s solar radiation is 93% of San Diego’s, and cooler temperatures make photovoltaics more efficient, because PV systems operate more efficiently at lower temperatures. [CleanTechnica]
