The new Energy bill signed by President Bush emphasizes the need for greater energy efficiency and promoting alternative fuel technology.
The climatic event El Niño, literally “the Baby Jesus”, was given its name because it generally occurs at Christmas time along the Peruvian coasts. This expression of climatic variability, also called El Niño Southern Oscillation (ENSO), results from a series of interactions between the atmosphere and the tropical ocean.
The US electricity distribution grid is around 100-years old and aging faster than new construction renews it while peak demand for electricity is projected to rise 19 percent nationally during the next decade--capital investments in electrical generation, transmission and distribution are forecast to grow by only 6 percent over the same period, according to the Electrical Power Research Initiative.
Celcon blocks have been chosen to provide a high level of both thermal and acoustic insulation for a new ‘green’ school, Winston Way Primary School in Ilford, Essex, for Redbridge Council. Celcon Hi Seven and Standard blocks were used for both the internal and external leaves of the building at ground floor level, to infill the Metsec steel frame. With a fully filled cavity the walls achieved a U-value of 0.25W/m²K.
The wait for a complete solar roof solution that blends seamlessly into a tile roof is over. Eagle Roofing Products, a division of Burlingame Industries, announced today the introduction of a comprehensive solar roofing system, the Eagle Solar Roof, to enhance the beauty of any architectural style.
Pacific Gas and Electric Company today announced that it has entered into a long-term, two megawatt (MW) commercial wave energy power purchasing agreement (PPA) with Finavera Renewables Inc. Located off the Northern California coast, the Humboldt County Offshore Wave Energy Power Plant will be developed by Finavera Renewables. The project is expected to begin delivering renewable, clean electricity in 2012.
To ensure a healthy future for all Americans, EPA is off and running in the race to develop a well-trained and diverse environmental workforce. EPA awarded 98 research fellowships in 2007 for students pursuing degrees in environmental studies through the Agency¡¦s Science to Achieve Results (STAR) and Greater Research Opportunities (GRO) programs.
Energy, housing and recycling solutions for the 21st century are among the research topics that will be presented at the TMS 2008 Annual Meeting & Exhibition, March 9-13, in New Orleans, Louisiana, USA. These topics are part of the “Materials and Society” vein of the meeting, which focuses on engineering solutions to some of society’s most perplexing problems.
Researchers at the U.S. Department of Energy¡¦s Brookhaven National Laboratory have unveiled important details about a class of catalysts that could help improve the performance of fuel cells. With the goal of producing ¡§clean¡¨ hydrogen for fuel cell reactions in mind, the researchers determined why two next-generation catalysts including gold, cerium, titanium, and oxygen nanomaterials exhibit very high activity. Their results will be published online in the December 14, 2007, edition of the journal Science.
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean¡¦s chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution¡¦s Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98% of present-day reef habitats will be bathed in water too acidic for reef growth. Among the first victims will be Australia¡¦s Great Barrier Reef, the world¡¦s largest organic structure.
