  • `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 ...

  • Canada to Study Wind Turbine Noise and Health

    Health Canada, in collaboration with Statistics Canada, will conduct a research study that will explore the relationship between wind turbine noise and health effects reported by, and objectively measured in, people living near wind power developments. "This study is in response to questions from residents living near wind farms about possible health effects of low frequency noise generated by ...

  • 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 ...

  • 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. ...

  • Micro wind turbines and wildlife: integrating plaplanning with ecology

    The ecological impacts of micro wind turbines (up to 50 kW) are treated in a diverse way by different local authorities in the UK during the planning approval process, research suggests. The study calls for ecologists, policymakers, planners and industry representatives to improve the integration of ecological information within planning, and for greater guidance for local authorities on the ...

  • New wind turbines to replace old in Germany

    Many of Germany’s wind turbine projects began in the late 1990’s and are now faced with declining output, thanks to wear and tear. Now with newer technologies surpassing old, and larger available wind turbines, it makes sense to start replacing older systems with new. As a result, Nordex will be replacing 16 legacy wind turbines with 9 newer models by the end of the year, at the ...

  • Offshore wind farm construction noise can displace harbour porpoises

    Noise caused by construction of Germany’s first offshore wind farm caused significant habitat disturbance for harbour porpoises, according to a recent study. Its results suggest that porpoises avoided areas up to 20 kilometres from the noise source during construction of the wind farm’s foundations. Development of offshore wind farms plays a major role in the shift towards renewable ...

  • The Torque - small wind turbine with maximum return at lower height

    The Torque is a small, modular build, vertical wind turbine of the newest generation, with countless advantages. Due to the sophisticated and patented design the Torque is the best working small wind turbine under all wind circumstances. The dynamic blade system optimizes the conversion of wind energy while moving with the wind direction and minimizes at the same time the loss of energy while ...

  • 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 of ...
