The presence of wind turbines repels bats in boreal forests
Author: Gaultier, Simon; et al.
Highlights Presence of Eptesicus nilssonii and Myotis spp. are higher further from wind turbines located in forests. The avoidance of wind turbines or their surroundings could mean important loss of habitats for bats. Bat activity at wind power sites in forests varies with night length and season in the boreal zone. Mitigating this avoidance effect in current and future wind farms requires stronger regulations in Finland and the rest of Europe. Abstract Impacts of wind power on bats are usually . . .

Impact of Hourly Wind Power Variations on the System Operation in the Nordic Countries
Author: Holttinen, Hannele
[abstract] The variations of wind power production will increase the flexibility needed in the system when significant amounts of load are covered by wind power. When studying the incremental effects that varying wind power production imposes on the power system, it is important to study the system as a whole: only the net imbalances have to be balanced by the system. Large geographical spreading of wind power will reduce variability, increase predictability and decrease the occasions with near zero or . . .

Indoor noise annoyance due to 3-5 megawatt wind turbines—An exposure-response relationship
Author: Hongisto, Valtteri; Oliva, David; and Keränen, Jukka
Abstract – The existing exposure-response relationships describing the association between wind turbine sound level and noise annoyance concern turbine sizes of 0.15-3.0 MW. The main purpose of this study was to determine a relationship concerning turbines with nominal power of 3-5 MW. A cross-sectional survey was conducted around three wind power areas in Finland. The survey involved all households within a 2 km distance from the nearest turbine. Altogether, 429 households out of 753 participated. The households were exposed to wind turbine noise . . .

Health problems in Finland caused by infrasound from wind turbines
Author: Tuulivoima-kansalaisyhdistys ry
From the English press release: Tuulivoima-kansalaisyhdistys (TV-KY) ry – the National Association of Citizens Against Giant Windmills – has recently released an extensive report on the infrasound emissions from wind turbines and their impact on people’s health. The wind turbines being built in close proximity to residential areas in Finland are the biggest in Europe. Their rotating blades generate low frequency noise and infrasound, i.e. frequent and continuous air pressure pulses that can travel for very long distances. Low frequency . . .
