Despite a very weak start to the year, IMS Research has recently increased its forecast for the full year by more than 1 GW and predicts more than 22 GW of new PV capacity will be added in 2011.
Cree, Inc. (unveiled a concept LED light bulb from its lighting research and development team. Redefining what is possible with high-performance LED lighting, the lamp delivers more than 1,300 lumens at 152 lumens per watt (LPW) using Cree TrueWhite Technology. Cree's prototype LED light bulb exceeds
A couple of weeks ago the U.S. Department of Energy (DOE) and the Ad Council launched a national education campaign to help consumers save money on utility bills. Videos, tips, an “energy savings IQ” quiz, and a photo gallery on Facebook - as well as videos posted on You Tube...
Independence Day was a blast, and summer is in full swing with vacations and day camps and whatever else we fill our spare time with when it's warm and sunny. This week, I noticed that the cicadas (kind of like grasshoppers but louder) started singing in the trees – a sign that the...
NREL and Semikron's new power block is poised to make connecting renewable energy to the electricity grid less expensive, more reliable.
On Monday, Shannon talked about how she's been using the online tools from the Advanced Technology Vehicle Data Center (AFDC) to help her decide what type of highly efficient vehicle may be best for her household. The AFDC provides excellent information such as a Light Duty Vehicle...
First Solar, Inc. announced it set a new world record for cadmium-telluride (CdTe) photovoltaic (PV) solar cell efficiency, reaching 17.3 percent with a test cell constructed using commercial-scale manufacturing equipment and materials. The test cell’s performance, confirmed by the U.S. Department of Energy’s National Renewable Energy Lab (NREL), far surpassed the previous record of
‘Smart’ PV inverter shipments are forecast to grow to 27 GW in 2015, accounting for almost 60% of the market compared to just 20% in 2010 according to the latest report from IMS Research.

Wind energy offers an environmental friendly fuel alternative to fossil fuel-generated electricity. Windmills are required to convert this “green” energy of the wind into electricity. Because of the remote location of many windmills, sensors serve as critical components in their operation, maintenance and safety.
Virginia Tech recently was named the overall winner of EcoCAR: The NeXt Challenge, a three-year collegiate vehicle engineering competition sponsored by the U.S. Department of Energy and General Motors (GM).
Rapidly falling prices in 1H’11 have been unable to stimulate the faltering European PV market, according to the latest Solarbuzz European PV Markets Report. Signs of a strengthening market in June 2011 were hit by cancellation of the anticipated mid-year incentive tariff reductions in Germany.
This week, Allison shared her experience of adding insulation to her attic. The result? A better-insulated home with less use of her air conditioning system. It's one of several things she's doing to keep her home cool during the summer (though insulation is effective year round)....
The Better Use of Light Bulbs Act (BULB) has been defeated in the House of Representatives. BULB would have amended the 2007 Energy Independence and Security Act, thereby staying the incandescent ban. But it was not to be. With no further challenges, the Edison Lightbulb faces mandatory retirement in January 2012.
A period of highly competitive pricing from PV module suppliers has led to gross margins declining by over 25% in the last six months, according to the latest analysis from IMS Research.
This year at my house, we have been on a quest to make our attic more energy efficient. I think we realized just how much this unseen area contributes to our overall comfort - not to mention what we pay to heat and cool the house.
