    1. Fraunhofer Off-grid PV Farming Solutions Without Storage

      Fraunhofer Off-grid PV Farming Solutions Without Storage
      The Fraunhofer energy management system monitors the amount of energy produced and then ensures that it is delivered to the devices that need it most. To illustrate, a submersible pump, which is 105 feet deep, can be powered to fill a reservoir when energy is available and the irrigation pump or desalination unit at other times. Only a relatively small battery is needed to ensure the CPV tracker and measuring system remains powered.

    2. Maui Rent-A-Space Co. installing 600kW Grid-Connected Solar Project

      Maui Rent-A-Space Co. installing 600kW Grid-Connected Solar Project
      AAAAA Rent-A-Space, a storage facility and commercial center in Honokowai, announced it has begun construction on the largest commercial photovoltaic power generation system in Maui County. The 600-kilowatt system will contribute to the state’s “feed-in tariff” program, with the capacity to feed 2880 kilowatt-hours into the island’s electrical grid each day, enough clean, renewable energy to power up to 220 Maui homes.

    4. PG&E Signs 3 Solar Power Purchase Agreements

      PG&E Signs 3 Solar Power Purchase Agreements
      The race to meet the toughest standard in the country for more clean power has intensified in California. Utilities such as PG&E and San Diego Gas & Electric have been busy inking contracts. Pacific Gas and Electric announced three power purchase agreements that collectively will generate 50MW. The three developers are Recurrent Energy, Westlands Solar Farms and Fotowatio Renewable Ventures.

    5. How Renewables and Storage will Replace German Nukes

      How Renewables and Storage will Replace German Nukes
      Existing energy storage options are being maximised and new battery technologies rolled-out. With more than 17,000MW of installed capacity, Germany boasts more than half the world’s operating photovoltaic solar energy panels. More than 21,000 wind turbines, most of them onshore, provide another 27,000MW, while offshore development of a further 25,000MW in the North Sea is planned by 2030. By 2050, the country expects to generate 80% of its electricity using renewable sources.

    6. Solar (w/ Storage) Will Move Appalachia From Coal

      Solar (w/ Storage) Will Move Appalachia From Coal
      Figure 7 shows the decrease in the consumer price per kilowatt-hour (kWh) for solar energy over time. This cost includes the cost to install solar, install energy storage (beginning in 2020), maintain the solar array, and building the transmission infrastructure. While this decrease may not look like much at first glance, it’s much more desirable than the dramatic cost increases in Figure 8 if we were to stick with coal.

    7. SDG&E & SolarGen2 Sign 25yr, 150MW Power Purchase Agreement

      SDG&E & SolarGen2 Sign 25yr, 150MW Power Purchase Agreement
      Solar Gen 2, a private solar development firm, signed a 25-year, 150-megawatt (MW) power purchase agreement (PPA) with San Diego Gas & Electric (SDG&E), a subsidiary of Sempra Energy. The photovoltaic solar project consists of three separate 50-MW sites where construction should begin during the first quarter of 2012 and expects to be completed by the third quarter of 2012. The Solar Project is located on private, fallowed land in the Imperial County, California.

      VC Cleantech investing drops by 1/3rd; New focus is efficiency
      VCs pumped $1.83 billion into 161 deals in N. America, Europe, China and India during the second quarter of this year, down 33 percent from the $2.75 billion in the second quarter in 2010, and 10 percent below the $2.03 billion that private cleantech companies raked in during the first quarter of this year. While solar was the biggest draw in 2010, energy efficiency technologies have been steadily attracting more money and deals in 2011.

    9. ABB Pumped Hydro Makes a Canary Island 100% Renewably Powered

      ABB Pumped Hydro Makes a Canary Island 100% Renewably Powered
      The project’s goal is to provide inhabitants with all the energy they need through a combination of wind energy, pumped water-storage power and solar-thermal and photovoltaic systems. ABB is helping to lead the project by providing technology to electrify and control the hydro-power plant and integrate energy from renewable sources into the island’s grid.

    10. Opinion: The Alternative Energy Fallacy

      Opinion: The Alternative Energy Fallacy
      The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices of those metals are even more volatile than the prices of the hydrocarbons that alternative energy hopes to supplant.
