Dead and deformed fish indicate selenium pollution from mountaintop coal mining is causing permanent damage to the environment and poses serious health risks, says a Wake Forest University biologist who will brief U.S. Senators on his research Feb. 23.
A holistic approach to data centers could result in millions of dollars of savings and a far smaller carbon footprint for the ever-expanding universe of information technology.
RTI International has developed a revolutionary lighting technology that is more energy efficient than the common incandescent light bulb and does not contain mercury, making it environmentally safer than the compact fluorescent light (CFL) bulb.
An advancement in hybrid electric vehicle technology is providing powerful benefits beyond transportation.
An international team of researchers has identified a new theoretical approach that may one day make the synthesis of hydrogen fuel storage materials less complicated and improve the thermodynamics and reversibility of the system.
A Baylor University researcher has used a new search method that he adapted for use on the seafloor to find a potentially massive source of hydrocarbon energy called methane hydrate, a frozen form of natural gas, in a portion of the Gulf of Mexico.
Engineers Find Significant Environmental Impacts with Algae-Based Biofuel, Offer Alternative to Production
With many companies investing heavily in algae-based biofuels, researchers from the University of Virginia's Department of Civil and Environmental Engineering have found there are significant environmental hurdles to overcome before fuel production ramps up. They propose using wastewater as a solution to some of these challenges.
Researchers from the Biotechnology Foundation Laboratories at Thomas Jefferson University have identified a way to increase the oil in tobacco plant leaves, which may be the next step in using the plants for biofuel. Their paper was published online in Plant Biotechnology Journal.
Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used.
If you've seen an Internet ad for capacitor-type power factor correction devices, you might be led to believe that using one can save you money on your residential electricity bill. A new NIST report explains why the devices actually provide no savings by discussing the underlying physics.
PNAS study by USC geobiologists documents new behavior of metal-metabolizing bacteria, with implications for design of microbial fuel cells.
A Soon-to-be graduate of Western Illinois University is one of lead researchers in market research project to foster new Russian market possibilities for Illinois ethanol producers. Ethanol co-product DDGS (distiller's dried grains with solubles) can provide high-protein feed product for Russian livestock.
Titanium dioxide can be converted into a material that absorbs sunlight and greatly increase the efficiency of solar energy cells. Coated particle fuel fabricated at ORNL, in cooperation with INL, General Atomics, and the Babcock & Wilcox Company, has set a world record for advanced high temperature gas-cooled reactor fuel. Electronic devices of the future may benefit from a fundamental discovery that allows researchers to customize the electronic properties of complex materials.
Last year, the United States overtook Germany to become the largest producer of wind energy in the world. This capped a five year expansion of U.S. wind power during which capacity increased by about a third every year.
A recent study concluded that 50 million U.S. acres of cropland and pasture could be used for the production of perennial grasses, such as switchgrass, for biofuel feedstock. Economically viable production of a perennial grass monoculture from which substantial quantities of biomass are removed annually is expected to require nitrogen fertilizer.
