The number of American "clean energy" jobs grew 9.1% between 1998 and 2007 , more than twice the growth rate of employment in the economy as a whole, according to a new study that claims to be the first "hard count" of the sector. The Pew Charitable Trusts found about 68,200 companies with 770,000 jobs in the clean energy sector in 2007 - roughly half a percent of today's US workforce. The study calls it "a strong start for a new economy still very much in its infancy". By comparison, fossil fuels industries, including coal, utilities, oil and gas, had about 1.27 million workers in 2007.
General Motors took a big step toward its reinvention as the "New G.M." today when it opened what it calls the largest automotive battery laboratory in the United States , a move the struggling company believes will hasten the development of electric vehicles. GM invested $25 million in the 33,000-square-foot Global Battery Systems Lab to develop and test the drive-trains underpinning the Chevrolet Volt and other hybrid, battery-electric and hydrogen fuel cell vehicles. The automaker believes the facility, at its sprawling Warren Technical Center campus outside Detroit, Michigan, will help make it a market leader in battery and EV technology.
The world's first full-scale floating wind turbine is being towed 10 kilometers southwest of Karmřy, Norway, where it will be anchored to the seabed using a three-point mooring system to start offshore trials. To be outfitted with a 65-meter-tall 2.3-megawatt turbine, the Hywind structure, a ballasted steel jacket called a 'spar buoy', will stretch 100 meters below the sea surface.
The country's wind power capacity will rise to 30,000 megawatts from 12,000 megawatts , Shi Lishan, deputy director of renewable energy at the National Energy Administration, said in Rudong city in the eastern province of Jiangsu today. China's wind power capacity was the fourth-largest in the world last year, according to Shi. Investment in alternative energy may exceed 2 trillion yuan by 2020, the National Development and Reform Commission, China's top economic planner, said in 2007. Wind power is "vital" as it is the cheapest form of renewable energy, Shi said. About 80 percent of the country's power is produced from coal.
BeyWatch is a 30-month research project supported by the European Commission (DG Information Society and Media) aiming at ICT tools for environmental management and energy efficiency. BeyWatch develops an energy-aware and user-centric solution, able to provide intelligent energy monitoring/control and power demand balancing at home/building & neighbourhood level.
Recent technological developments in the electro-reduction of carbon dioxide to formic acid, a valuable chemical with possible application in the steel pickling process, may offer an alternative to expensive large scale carbon capture and storage operations.
Waste-to-energy plants based on gasification are high-efficiency power plants that utilize municipal solid waste as their fuel rather than conventional sources of energy like coal, oil or natural gas.
Over the past 10 years, Sheila Davis has played a valuable role at SVTC and in shaping environmental policy in the high-tech industry. She is one of the co-founders of the Computer TakeBack Campaign and sits on its steering committee. In 1996 she researched and developed the first electronic recycling legislation to reach the California Governor's desk and in 1999 spearheaded the first pilot programs in the country to collect and recycle electronic waste from the residential curbside.
With more than 40 sessions covering everything from producers to users of hydrogen, the conference featured its most relevant content to date, presented by some of the biggest names inside and outside the industry.
On average, it could be assumed that 15% of the world total consumption of diesel, gasoline and jet fuels can be replaced by lignin.
This month, the Obama Administration proposed cutting more than $130 million for hydrogen and fuel cells, and a total elimination of funds for the fuel cell vehicle program. This unfortunate position is short-sighted, and could prove disastrous. Abandoning these programs now will drive technology and innovation overseas and obstruct private investment. It will also waste state and federal dollars, stifle a burgeoning industry and limit options to fight climate change.
Only about 12 to 20 percent of the energy produced by the engine actually turns the wheels, and about one-third of that is consumed by rolling resistance. As you drive down the road, your tires squirm and deform every time you go around a corner, accelerate, or apply the brakes. The repeated tire deformation between the tire and the road, within the tire and between the tire and the rim, causes mechanical energy to be converted to heat; hence additional mechanical energy must be supplied to drive the axle.
How ultra low power wireless networks and energy harvesting are going to make our planet a better place to live.
The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) today released its annual assessment of leading utility green power programs. Under these voluntary programs, consumers can choose to help support additional electricity production from renewable resources such as wind and solar.
The Obama administration has made alternative fuel research a key objective for the country. Researchers in the area of hydrogen fuel cell research therefore are faced with a plethora of peer reviewed publications that they must read to stay abreast of not only the latest publications but also historical publications that may be relevant to a current discovery.

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGripâ„˘ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
