An increasing number of cities around the world now include preparations for climate change in their basic urban planning - but only a small portion of them have been able to make such plans part of their economic development priorities, according to a unique global survey of cities released today.
Researchers at the National Institute of Standards and Technology (NIST) have developed a laser-based instrument that generates artificial sunlight to help test solar cell properties and find ways to boost their efficiency.
Setting strong standards for climate-changing carbon emissions from power plants would provide an added bonus - reductions in other air pollutants that can make people sick; damage forests, crops, and lakes; and harm fish and wildlife. This, according to a first-of-its-kind study released today by scientists who mapped the potential environmental and human health benefits of power plant carbon standards.
A Rotterdam based research and development company reveals that it has developed a totally new generation of wind turbines for domestic use. This wind turbine will gain much more energy out of the wind than current generation wind turbines.
The integration of biomethane in concentrating solar thermal power plants would facilitate the commercial introduction of concentrating solar power (CSP) technology in the energy market, reducing both financial and environmental costs.
A modern wind farm usually consists of multiple wind turbines arranged in an organized pattern or array. Wake interferences among wind turbines have been found to affect the performance of the wind turbines significantly. Researchers studied the effects of relative rotation direction of wind turbines on the wake interferences among tandem turbines for improved power production performance of wind turbines in a wind farm.
Turning the 'hydrogen economy' concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels.
