Conventional methods of filtering waste water in sewage treatment plants are unable to completely remove medicine residues such as the estrogens in birth control pills. Students from the Bielefeld University's Center for Biotechnology have now developed a biological filter in which specific enzymes (so-called laccases) break down these medicine residues.
The island nation of Tokelau switched on the third and final installment of its new solar energy grid last week, earning praise around the world as the first country to become entirely solar-powered - except it's not a country.
Mankind's emissions of fossil carbon and the resulting increase in temperature could prove to be our salvation from the next ice age. According to a new research article by researchers from the University of Gothenburg, the current increase in the extent of peatland is having the opposite effect, cooling down the climate.
A study to determine whether energy production can simultaneously be used to positively affect regional climates, including modifying rainfall patterns, has begun in CSIRO’s weather and energy research unit.
The Intersolar AWARD for the category Solar Projects in India was presented for the first time at Intersolar India, India's largest exhibition and conference for the solar industry. The international solar industry prize pays tribute to companies for particularly outstanding solar projects.
Researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) are learning how to better understand these issues and are working toward effective solutions for the wind industry. Their goal is to maximize turbine performance and minimize structural loads, which will ultimately result in lower-cost wind energy. Toward that goal, NREL researchers are leveraging the lab's supercomputing resources and have developed high-tech modeling and simulation capabilities.
How accurate is the latest generation of climate models? Climate physicist Reto Knutti from ETH Zurich has compared them with old models and draws a differentiated conclusion: while climate modelling has made substantial progress in recent years, we also need to be aware of its limitations.
The University of British Columbia (UBC) announces the international patent filing for a Battery type Solar/Light conversion cell. This unique generator and storage approach allows both solar power generation and storage within a single cell. Based on photosynthesis, it can be implemented using abundant and readily replenished and renewable biomaterials.
A special issue of the Bulletin of the Atomic Scientists, published by SAGE, “The German Nuclear Exit,” shows that the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits, with one top expert calling the German phase-out a probable game-changer for the nuclear industry worldwide.
The huge energy needs of skyscrapers mean that these towers are not only office buildings, they're polluters with smokestacks billowing out toxins from the rooftop. Our cities are dirtier than we think. New research from Concordia University just might clean them up.
