Does living near wind turbines negatively impact human health?

Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as 'annoying.' They claim this nuisance negatively impacts their quality of more

Construction delays make new nuclear power plants costlier than ever

The cost of building new nuclear power plants is nearly 20 percent higher than expected due to delays, a new analysis has more

Can we get 100 percent of our energy from renewable sources?

Some researchers doubted the feasibility of many of the recent scenarios for high shares of renewable energy. Now scientists have hit back with their response to the points raised. They demonstrate that there are no roadblocks on the way to a 100 percent renewable more

European wind energy generation potential in a 1.5 degree C warmer world

The UK and large parts of northern Europe could become windier if global temperatures reach 1.5 degrees C above pre-industrial levels, according to a new more

Impacts of windfarm construction on harbor porpoises

Scientists from Germany, Denmark and the UK have built a model tool to predict what happens to marine animals when exposed to noise from the construction and operation of wind farms at more

Natural gas prices, not 'war on coal,' were key to coal power decline

Steep declines in the use of coal for power generation over the past decade were caused largely by less expensive natural gas and the availability of wind energy -- not by environmental more

Environmental impact of electric vehicles in China? It depends on how they are charged

Electric vehicles play a key role in China's plan to improve air quality and reduce CO2 emissions but, with the majority of China's electricity still coming from coal-fired power plants, many question just how effective this strategy will be. Now, researchers have found that how electric vehicles are charged -- whether in the low-energy slow mode or high-energy fast mode -- plays a significant role in the reduction of CO2 and the integration of wind more

New control strategy helps reap maximum power from wind farms

Researchers have developed a way to extract more power from the wind. The researchers used supercomputers at the Texas Advanced Computing Center to filter out the effects of turbulence and apply control algorithms that can better manage the operation of wind farms. The approach has the potential to increase wind power generation by 6-7 percent with a estimated increase in revenue of more than $600 million more

Silent marine robots record sounds underwater

Silent marine robots that record sounds underwater are allowing researchers to listen to the oceans as never before. While pilot whales make whistles, buzzes and clicks, pods of hunting dolphins create high-pitched echolocation clicks and larger species such as sperm whales make louder, slower clicks. As well as eavesdropping on marine life, the recordings can be used to measure sea-surface wind speed and monitor storms. The research will be presented at the General Assembly of the European Geosciences Union, more

Chirping is welcome in birds but not in fusion devices

Birds do it and so do doughnut-shaped fusion facilities called 'tokamaks.' But tokamak chirping -- a rapidly changing frequency wave that can be far above what the human ear can detect -- is hardly welcome to researchers who seek to bring the fusion that powers the sun and stars to more
