Detection of wind turbines rotary motion by birds: A matter of speed and contrast
Conservation Science and Practice, Volume 5, Issue 10, October 2023., 2023 Some bird species may detect low‐speed rotation on wind turbines as static. A low contrast between the wind turbine and its background increases the rotation speed treshold at which this phenomenon appears. Automatic Detection Systems used to slow down wind turbines when birds are approaching may thus be counterproductive.

Animal Conservation, Volume 26, Issue 2, Page 264-275, April 2023., 2023 We demonstrate on a short‐lived, endangered raptor species, the Lesser kestrel, that additional mortality due to windfarms can have a negative impact on population growth rate. Although the impact is currently moderate, the forecasted decrease in immigration rate, and increase in the number of windfarms at a wider scale, may threaten the recovery of ...

Wind Turbines, Public Acceptance, and Electoral Outcomes
Swiss Political Science Review, Volume 28, Issue 4, Page 712-727, December 2022., 2022 Abstract Despite a widespread public support for wind energy in general, wind turbine proposals attract a considerable amount of public opposition. At a time of political commitments to building more wind turbines for climate risk mitigation, we study the potential causes of this opposition and its electoral effects.

Journal of Applied Ecology, Volume 59, Issue 8, Page 2142-2153, August 2022., 2022 This study provides empirical evidence that wind turbines close to optimal habitats such as hedgerows strongly repel bats, while wind turbines located farther away in open areas could attract them. Increased risks of collisions and habitat losses near edges strengthen the importance of keeping wind turbines at a sufficient distance from woody edges (e ...

Assessment of Turbulence Models for Flow Simulation around a Wind Turbine Airfoil
Modelling and Simulation in Engineering, Volume 2011, Issue 1, 2011., 2011 This investigation focuses on the application of the computational fluid dynamics tool FLUENT to the study of flows over the NACA 63–415 airfoil at various angles of attack. With the aim of selecting the most suitable turbulence model to simulate flow around ice‐accreted airfoils, this work concentrates on assessing the prediction capabilities of ...

Journal of Applied Ecology, Volume 62, Issue 6, Page 1437-1448, June 2025.Data from automatic detection systems are a promising non‐invasive approach that requires few human and logistical resources to develop a more comprehensive bird collision risk mitigation strategy. They can be valuable to biodiversity stakeholders to highlight environmental factors that locally increase bird exposure and sensitivity, to avoid ...

Wind Energy, Volume 28, Issue 2, February 2025.ABSTRACT The installation of automatic detection systems (ADSs) on operating wind energy facilities is a mitigation measure to reduce bird collisions. The effectiveness of an ADS depends on a combination of parameters, including the detection distance of the bird, its flight speed, and the time to complete the chosen action (e.g., turbine shutdown). We
