  • Climate Change on Obama’s Second-Term Agenda

    Among the surprises in President Barack Obama’s second Inaugural Address on Monday was his promise to address the challenges of climate change and sustainable energy. An independent draft report released about a week earlier on climate change and its impacts in the U.S. may have helped to fuel his renewed resolve on these intertwined issues.

  • Report: U.S. Has Lost Edge in Global Renewables Race

    Once a world leader in innovation and manufacturing of clean energy technologies, the U.S. now faces significant competitive challenges from Europe and Asia, and it lags behind other nations on measures that include renewables deployment, manufacturing, and innovation, a new report suggests.

  • Floating Solar—on Water

    The recent explosive growth of massive solar plants in some of the world’s most remote deserts has stolen some of the spotlight from smaller solar installations that float on water. But in November, a concept proposed by researchers at Norwegian foundation DNV (Det Norske Veritas) for a dynamic floating offshore solar field concept stirred up myriad possibilities, particularly for congested urban regions such as coastal megacities.

  • Slow Growth Ahead—with Unexpected Flares of Activity

    North American shale gas was supposed to realign the generation fleet here and abroad (thanks to anticipated exports) far into the future. Turns out, that’s not exactly how the near term is shaping up. Despite stagnant (and even putrid) economies and legislative bodies in the U.S. and EU, there promises to be sufficient market volatility to keep everyone alert.

  • TOP PLANT: Stillwater Solar-Geothermal Hybrid Plant, Churchill County, Nevada

    The Stillwater hybrid facility is the world’s first renewable energy project that pairs geothermal power’s baseload generation capacity with solar power’s peak capacity. Inaugurated in May, the 26-MW solar plant is integrated with the adjacent 33-MW geothermal plant, which began operations in 2009, and provides energy to run the geothermal plant’s auxiliary loads.

  • Distributed Solar Challenges Utilities, Markets, and Regulation

    Electricity produced from solar energy is being added to the grid—before and after the meter—in greater amounts each year. The uniqueness of this resource is pushing utilities, developers, users, and regulators to develop new and innovative interconnection rules and to rewrite some old rules that balance the costs and rewards among stakeholders.

  • Renewable Energy Development Thrives During China’s 12th Five-Year Plan

    China’s 12th Five-Year Plan calls for expanding the use of renewable energy in all forms throughout the country. From solar and wind to biomass gas and briquettes, China has a true “all of the above” renewable energy policy.

  • Hawaii’s Largest Wind Project Online as State Struggles to Integrate Renewables

    On Monday, as First Wind announced its 69-MW Kawailoa Wind Project had gone into commercial operations on Oahu, other news underscored the difficulty the island state faces in trying to substitute renewables for expensive, imported fossil fuels.

  • European Solar Initiative to Source Power from North Africa Hits Blocks

    The Desertec Industrial Initiative (Dii) oversees a $508 billion initiative to establish 6,500 square miles of concentrated solar power plants in the vast African and Middle Eastern deserts.
