Are motorways the best spot for wind turbines?
Wind turbine noise can be detected at low levels, even when it is heard alongside motorway traffic noise, a study finds. It is possible for louder motorways to drown out turbine noise, however. The participants in this listening experiment could easily detect wind turbine noise, but only once they knew it was present in recordings of environmental noise. Public annoyance with wind turbine noise ...

Environmental Protection UK urges joined-up thinking and sound guidance on wind turbine noise assessment
Environmental Protection UK welcomes guidance published today by DEFRA, which aims to help local authorities investigate complaints about noise from wind farms. his comes after the publication of DECC commissioned research last week, that highlighted the need for clear, up to date guidance on how wind turbine noise impact is assessed in development proposals, which is urgently needed to reduce ...

Wind turbines not a risk to human health, says MIT study
The review took into consideration health effects such as stress, annoyance and sleep disturbance among others that have, in the past, been raised in association with living close to wind turbines. "No clear or consistent association is seen between noise from wind turbines and any reported disease or other indicator of harm to human health" the study found. The MIT authors considered a number ...

Sail-inspired turbine promises cheaper wind energy
A Tunisian invention that harvests wind energy through adesign inspired by sailboats promises cheaper, more efficient wind energy. The bladeless wind turbine, the Saphonian, named after the wind divinity that was worshipped by the ancient Carthaginians, also promises to be more environmentally friendly than existing wind turbines that produce noise and kill birds through their blade rotation. ...

2013 Updates (Through March 31, 2013) from the Eppic Environmental & Alternative Energy Index
This year-end summary lists an additional 19 conferences since August. This slight decline for the year in conferences resulted from more Mega-Conferences and more high-volume entries in usual conferences. Still, 97 conferences were indexed while continuing monthly updates of 116 journals & magazines publishing environmental & renewable energy articles & papers. Through December, over ...

`Anti-noise` silences wind turbines
If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times: One source is the motion of the rotor blades, another is the cogwheels that produce vibrations in the gearbox. These are relayed to ...
