Last week, the Environmental Protection Agency announced its new green homes Web site. The site provides an interactive experience that helps people
This week, John discussed buying clean electricity from your utility. If you can't set up a small renewable energy system of your own, buying clean electricity is a great way to support the use of renewable energy.
The exterior skin of NREL's newest building will do more than keep the weather out. The concrete panels actually will be part of the Research Support Facilities' heating and cooling system. It's an old idea brought back to life in the name of energy efficiency.
Driving hydrogen fueled SUVs for 431 miles per fill-up is no longer a California dream. Researchers from NREL and Toyota recently completed a 331 mile round trip drive between Torrance and San Diego in two Toyota Highlander Fuel Cell Hybrid Vehicles. And, with the fuel remaining, those...
A certain eco-conscious purveyor of roasted beans (rhymes with dar-nucks) has announced plans to adopt solid state lighting in more than 8,000 stores by the end of next year. Utilizing GE lighting solutions, Starbucks has already “converted” more than 1,000 U.S. locations, with plans to address the international market in March 2010.
Russia has jumped on the CFL bandwagon, and decided to ban the incandescent bulb. As of January 1, 2014, the manufacture and sale of all incandescent bulbs will be prohibited in Russia.
Back in March, we reported on the California Energy Commission’s proposal to set a cap on the maximum active mode power usage (watts) for TV’s. All units above the maximum would be banned for sale in California—this would preclude the vast majority of Plasma, DLP, and Rear-projection TV’s.
Earlier, we reported that global investments in renewable energy had dipped 40% from 2008-09—thus, the following comes as welcome news. George Soros has decided to invest $1 billion of his own money into “green technologies.” Soros issued a clear directive on how his money ought to be spent
Helix Wind Corporation gave an update today on its efforts to provide cost-effective renewable energy solutions to telecommunications companies. Helix’s wind turbines can lower the costs of operating expenses associated with cell phone towers in remote locations.
The Fraunhofer Institute for Chemical Technology (ICT) has developed a redox flow battery that could become the gold standard in Advanced Technology Vehicles. If the claims hold up, this battery would be a true breakthrough. There’s nothing revolutionary about the concept of redox flow batteries.
Residents of a West Bank village with no electricity have been helped out of the darkness by unlikely benefactors - a group of Israelis who installed solar panels and wind turbines to illuminate the Palestinians' makeshift homes. The villagers of Susya live in tents and caves with power lines darting right above their dwellings
Global investments in renewable energy technology dipped 40% from 2008-09—this according to United Nations Industrial Development Organization Director, General Kandeh Yumkella. “Due to the current economic crisis we have seen almost a 40 percent decline in 2009 alone in these investments,” said Yumkella at a global conference on green energy in central Mexico.
From strawberry jam jars to frozen french fries, the manufacturing plants that make several well-known container and food items in the United States can now earn the U.S. Environmental Protection Agency’s Energy Star for superior energy efficiency. The new Energy Performance Indicators (EPIs) for flat and container glass manufacturing plants
The organic light emitting diode (OLED) display is becoming more and more popular, especially for mobile phones, media player and small entry level TVs. Contrary to a standard liquid crystal display, the OLED pixel is driven by a current source. To understand how and why the OLED power supply impacts the display picture quality, it is key to understand the OLED display technology and power supply requirements.
Toshiba will become a big player in optoelectronics—if their lighting division has its druthers. The company will release high-output LED light bulbs with a total flux equivalent to that of a 60 W incandescent lamp. The “natural white” type and the warm white type feature total fluxes of 810 lm and 600 lm, respectively.
Dow Chemical Co said on Monday it would begin selling a new rooftop shingle next year that converts sunlight into electricity -- and could generate $5 billion in revenue by 2015 for the company. The new solar shingles can be integrated into rooftops with standard asphalt shingles, Dow said, and will be introduced in 2010 before a wider roll-out in 2011.
OSU has earned top honors at the 2009 finals of the Year One EcoCar competition. The OSU stable bested 16 other teams with their “Extended Range Electric Vehicle” design. The spiritual successor to Challenge X, EcoCar is a three-year collegiate advanced vehicle technology engineering competition
RoseStreet Labs Energy (RSLE) has created what they assert to be the world’s first tandem nitride/silicon solar cell. RSLE combined a silicon solar cell with a Nitride Thin Film to create their hybrid photovoltaic cell. According to RSLE, this hybrid will achieve “practical efficiencies” of 25-30% (typical efficiencies range from 12-20%).
Japanese companies are being forced to foot the bill for an ambitious new national solar power program. According to Alpha Solar, “the government will oblige all Japanese companies to purchase excessive amount of energy and pay the double price to help installing solar panels.” The total “obligation” equals 9 billion Yen, and this will filter down to the consumer.
Phillips has been recognized as the first entrant in the Department of Energy’s Bright Tomorrow Lighting Prize (L Prize) competition. Intended to spur development of efficient LED replacements for incandescent bulbs, L Prize comes with a handsome reward--$10 million to the first group or individual to develop a 60 W replacement.
The U.S. Department of Energy today announced this year’s participants and dates for DOE’s 2009 Solar Decathlon, a competition that challenges students to design and develop houses that can provide their own energy from the sunlight – a clean, renewable source of energy. The twenty collegiate teams from the United States, Canada, Spain and Germany will each build a completely self-sufficient solar powered house
Fusion is the power source of the future, goes the old saw. And for fifty years, it has always been "fifty years in the future." That may be changing with a number of new small fusion projects in the works or doing actual experiments. Let me mention first the ITER experiment (a tokamak design) which is the fusion project every one knows about.
The Cree LR6-DR1000 recessed downlight was awarded the Grand Prize at the 2009 Lighting for Tomorrow - Solid State Lighting Competition. A repeat winner, Cree shared the prize with Philip's Color Kinetics for its eW Cove Powercore. The Cree LRP-38, a PAR38 bulb, and the LR6-HE (high-efficiency) were also recognized with Special Focus Awards for technical innovation and high efficiency, respectively.
Panasonic has released an LED bulb that purportedly lasts 19 years. The drawback? It’s only available in Japan (for now, anyway). Could the EverLed line jumpstart solid state lighting? According to Panasonic, the screw-in LED bulb lasts 40 times longer than equivalent incandescents. Obviously, independent testing is needed, but this is an impressive figure.
The startup Aptera was recently denied a DOE loan for its Aptera 2e electric vehicle. Their three-wheeled, *ahem*, “curiosity,” didn’t match the loan criteria, but the incident raises an important question—should the government be sponsoring products in the private sector?
