Silicon-based light bulbs a big step closer The Wall Street Journal Share     Silicon has shaken up many industries. A startup called Bridgelux says the next big target will be light bulbs. The Livermore, Calif., company claimed a breakthrough in using the material to fabricate LED. A key barrier to wider use of LEDs is high cost — $40 price tags aren't uncommon for 60-watt equivalent bulbs — and that's where silicon could come in. More Incandescent: The 5 stages of grief The Economist Share
Across the nation, ordinary Americans are slowly waking up to the terrible loss of an old friend: the incandescent light bulb. Four years ago, the government realized it was old and inefficient technology, needlessly costing billions in wasted energy every year. So it legislated efficiency standards that are set to outlaw most incandescent bulbs in 2012. So far, public reaction has been rather similar to that in Europe. Nobody made much of a fuss when the laws were being discussed and passed. Everyone knew it was coming, and from a distance could even understand the logic, but we all decided it wasn't happening to us.

Nearly 2,000 tiny lights shine from the ceiling of Wendy Davis' Maryland laboratory, allowing the "vision scientist" to come up with measurements for energy-saving lighting for homes and businesses. The Vision Science laboratory that Davis established and leads at the National Institute of Standards and Technology — the only one of its kind in the world — runs experiments with LEDs now used in traffic signals, nightlights and backpackers' headlamps. Since the lab opened in 2009, Davis and her colleagues have developed a metric for a new color-rendering standard with the potential to replace a decades-old one. More Global economic conditions still challenge renewable energy growth FM Link Share
Despite record global investment in renewable energy in 2010, the continuing impacts of the global financial crisis are placing renewable energy markets in a state of flux, according to a recent report by Ernst & Young. The company's latest Renewable Energy Country Attractiveness Indices still place China in the top spot, thanks largely to the country's 64 percent growth in wind power capacity in 2010. More GSA strives to be 'green proving ground' for net-zero energy use GovernmentExecutive.com Share
With all new government buildings required to be net-zero by 2030, the General Services Administration has begun converting some existing facilities to attain net-zero usage in an effort to learn what works and what does not. It aims to emerge as a "green proving ground" for other agencies and the private sector. GSA has announced plans to convert two existing buildings to net-zero status. One is the Wayne Aspinall Federal Building and Courthouse in Grand Junction, Colo., which will become the nation's first net-zero historic building when renovations are complete in 2013.The second is the San Ysidro Land Port of Entry in California, the nation's busiest border crossing, which will be net-zero by 2014.
