Scaling up the production of biofuels made from algae to meet at least 5 percent – about 10 billion gallons – of U.S. transportation fuel needs would place unsustainable demands on energy, water and nutrients, says a new report from the National Research Council.
Wind energy in Colorado each year saves a billion gallons of water while avoiding emissions of air pollutants equivalent to that produced by half a million cars. Between 2000 and 2011, production of electricity from wind energy in Colorado grew from zero to 4.7 million megawatt-hours (MWh), and is now producing nearly 10 percent of the state's electricity.
Rubber residues can be downcycled to floor coverings and safety crashpads, and for the first time, also processed into high-quality plastics. A new kind of material makes it possible: the environmentally-friendly material mix is called EPMT.
It may seem as though the German plains are all but tapped out when it comes to wind energy production. To refute this theory researchers are sending stunt kites into the skies to harness the wind and convert the kinetic energy generated into electricity.
A new project of scientists at UCSB's National Center for Ecological Analysis and Synthesis (NCEAS) and partners aims to synthesize existing research on tipping points in marine ecosystems and conduct case studies to devise a set of early warning indicators and management tools that may help to predict, even prevent, threatened systems from falling off the precipice.
Danish industrial enzymes maker Novozymes on Tuesday launched an enzyme that it said produces more ethanol from corn, addressing concern that growth in biofuels has come at the expense of food production.
University of British Columbia researchers have invented a safe, efficient technology to wirelessly charge electric vehicles using "remote magnetic gears" and successfully tested it on campus service vehicles.
Researchers from the Technological, Environmental and Logistics Centre (TEC Ltd) in Slovenia have successfully transformed waste from paper mills into a product that can effectively soak up fuel from leaks or oil from spills.
A research team led by a scientist from UC Santa Barbara and supported by the National Science Foundation (NSF) has retrieved data from a sensor in Antarctic waters that survived the harsh polar winter. The information it gathered will provide critical baseline data on the changes in chemistry, or acidification, of those remote seas.
