  • The Next Big Challenge for Energy Storage
    The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in history it will become feasible to store electric energy.
  • Listen Up: What's the Deal with Solar Trackers?
    In the early solar PV days, trackers were a necessity to maximize the energy output from very expensive solar modules. Unfortunately, in those days trackers were mechanically complex and unreliable (remember TV antenna rotors?), and the control systems were expensive and finicky. As solar module pricing declined, the interest in trackers for small systems began to wane.
  • Renewable Energy Accounts for 100 Percent of New US Electrical Generating Cap...
    According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, all new U.S. electrical generating capacity put into service in July came from renewable energy sources: 379 megawatts (MW) of wind, 21 MW of solar, and 5 MW of hydropower.
  • Australia Chills Hopes for $20 Billion Clean Energy Industry
    Australia is frightening developers away from renewable energy even before the government decides whether to overhaul targets for the industry?s growth.
  • Lubricating Energy Policy
    The new report from the Taxpayers for Common Sense shows that oil companies paid just 11.7 percent of their U.S. income in federal taxes over the last five years, and the ?smaller? companies included in the study that reported positive earnings only paid 3.7 percent. To achieve such a low tax rate, oil companies were able to take advantage of special tax breaks and loopholes that allowed them to defer more than $17 billion in taxes they would have otherwise owed.
  • Solar Boom Drives First Global Panel Shortage Since 2006
    The solar industry is facing a looming shortage of photovoltaic panels, reversing a two-year slump triggered by a global glut.
  • Open Season: Japanese Government Seeks to Deregulate Utility Market, Boost Re...
    While most U.S. customers are only able to get green electricity by either purchasing and installing their own system or acquiring a lease or power purchase agreement through a third-party company like SolarCity, Japanese customers will soon have another option. Homeowners and businesses unable to install their own systems will be able to purchase green electricity from existing installations, and those solar electricity providers will be able to receive similar benefits as utilities.
  • A Future for Flywheel Storage? Alaskan Project May Lead to Technology Uptick,...
    Beacon Power LLC predicts an Alaskan island?s use of its flywheels to store energy from a power plant will pave the way for more widespread application of the technology to help cut the use of fossil fuels.
  • Recycling Old Batteries into Solar Cells
    This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries ? a potential source of lead pollution ? into new, long-lasting solar panels that provide emissions-free power.
  • The Power of Collective Energy Purchasing
    "We can't do it as an individual, but four hundred communities aggregating and asking for local wind power and solar power ? that's really powerful." Oak Park, IL, is one of hundreds of Illinois towns using their authority to buy electricity in bulk on behalf of its residential and small business customers. So far, most communities have used the po
  • Chinese Solar Tariffs Could Slow Renewable Energy Adoption in the US
    From the State of the Union address in January to a recent California fundraising swing, President Barack Obama has missed few opportunities to tout the nation?s use of renewable energy to fight climate change.
  • Plans for World's Largest CPV Plant Scrapped Due to Australia's Wavering Rene...
    Plans to build the world?s largest solar power plant of its kind have been scrapped in Australia after the developers raised concerns about the government?s commitment to clean energy.
  • A Tipped Scale in California: Time to See the True Value of Geothermal
    In 2004, California Public Utilities Commission (CPUC) passed the least-cost best fit (LCBF) rule as part of California?s Renewable Portfolio Standard procurement. This statute required utilities to select renewable resources that have the lowest cost and that best fit their system needs.
