Shifting winds in turbine arrays
Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below.
Intermittence of wind energy hardly affects CO2 emissions in Spain
Researchers at the UPM have found that real contribution to emissions targets is positive even in energy markets with high penetration of wind energy.
NREL calculates emissions and costs of power plant cycling necessary for increased wind and solar
New research from the Energy Department's National Renewable Energy Laboratory (NREL) quantifies the potential impacts of increasing wind and solar power generation on the operators of fossil-fueled power plants in the West. ...
Clean energy least costly to power America's electricity needs
It's less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study published in Springer's Journal of ...
German energy giants pull plug on conventional power
German power company RWE is shutting six domestic plants and rival E.ON is threatening to relocate to Turkey as the sector tots up the cost of the government's energy policy turnaround.
Localized wind power blowing more near homes, farms and factories
Americans are increasingly installing wind turbines near their homes, farms and businesses to generate their own energy, concludes a new report released today.
Wind power does not strongly affect greater prairie chickens, 7-year study finds
Wind power development does not ruffle the feathers of greater prairie chicken populations, according to the results of a seven-year study from a Kansas State University ecologist and his team.
Policy issues plague hydropower as wind power backup
Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to Penn State researchers.
Study shows wind and solar plant benefits vary by location
Autonomous energy-scavenging micro devices will test water quality, monitor bridges, more
Out in the wilds or anywhere off the grid, sophisticated instruments small enough to fit in a shirt pocket will one day scavenge power from sunlight, body heat, or other sources to monitor water quality or ...
New hybrid technology set to change the future of renewables
A new hybrid technology that integrates wind and solar power generation is set to overcome many of the problems associated with traditional renewable power systems and revolutionise the green energy sector.
Google to power Finnish data centre with wind energy
Google said Tuesday it had entered a ten-year deal with a Swedish wind farm developer to power a data centre in Finland.
Want to move up at work? Be a true believer
New research is tweaking an old adage about how to get ahead in a competitive workplace: It's not just who you know, but what you believe in.
Wind power blows into Africa
Giant turbines churning in the wind are a rare sight in Africa—but that will not be the case for long. Until now the meagre amounts of investment in African wind energy have predominantly come from governments ...
