Amid growing concern over the surprisingly large amount of greenhouse gas produced by the Internet and other telecommunications activities, researchers are reporting new models of emissions and energy consumption that could help reduce their carbon footprint.
By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present (almost 400 parts per million) were systematically associated with sea levels at least nine metres above current levels.
The new monitoring will include not only PM2.5, but also sulfur dioxide, nitrogen dioxide, ozone and carbon monoxide, the Xinhua news agency said, citing a Friday announcement by the Ministry of Environmental Protection.
Industries across Europe are threatened as European Union emission rules for Volatile Organic Compounds are tightened. Now an aircleaning invention from the University of Copenhagen has proven its ability to remove these compounds.
ACTIVEWINDFARMS ('Active wind farms: optimization and control of atmospheric energy extraction in gigawatt wind farms') is investigating ways to introduce optimal techniques for improved control of the interaction between large wind farms and the atmospheric boundary layer.
The storage capacity of concentrating solar power can add significant value to a utility company's optimal mix of energy sources, a new report by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) suggests.
Researchers will use the five-year, $9 million grant from the U.S. Department of Energy (DOE) to design solar energy systems and installation and connection procedures that require little or no customization by homeowners and installers.
Scientists have developed and patented a type of biological concrete that supports the natural, accelerated growth of pigmented organisms. The material, which has been designed for the fašades of buildings or other constructions in Mediterranean climates, offers environmental, thermal and aesthetic advantages over other similar construction solutions.
Surfaces with photo-catalytic characteristics clean the air off nitrogen oxides and other health-endangering substances. Using a new test procedure, Fraunhofer researchers can find out how the coatings behave during a long-term test.
Stanford researchers have succeeded in developing the world's first peel-and-stick thin-film solar cells. Unlike standard thin-film solar cells, the peel-and-stick version from Stanford does not require any direct fabrication on the final carrier substrate.
