Short Science Summary: Collision Risk Modeling – A Tool for Assessing Risks to Raptors at Wind Energy Facilities

Raptor

In January 2022, the International Energy Agency Wind Task 34—Working Together to Resolve the Environmental Effects of Wind Energy (WREN)—organized a forum to discuss aspects of raptor collision risk with wind turbines. The forum included experts in raptor biology and physiology, collision risk modeling, wind energy development, and atmospheric scientists from seven countries. They represented a range of international stakeholder groups including academia, government agencies, national laboratories, and wildlife consultants. This educational brief, produced by WREN under IEA Wind, summarizes the discussion during the forum and written comments from those who could not attend. Relevant literature was used to provide additional context when needed. A list of the references used to develop this summary is available here. 

Collision Risk Modeling – A Tool for Assessing Risks to Raptors at Wind Energy Facilities (English)

En enero de 2022, la tarea eólica 34 de la Agencia Internacional de Energía, "Trabajando juntos para resolver los efectos ambientales de la energía eólica (WREN)", organizó un foro para analizar los riesgos de colisión de aves rapaces con aerogeneradores. El foro incluyó a expertos en biología y fisiología de aves rapaces, modelos de riesgo de colisión, desarrollo de energía eólica, y científicos atmosféricos de siete países. Representaron a una variedad de grupos de partes interesadas internacionales, incluidos académicos, agencias gubernamentales, laboratorios nacionales y consultores de vida silvestre. Este resumen educativo incluye las conversaciones presentadas en el foro y los comentarios escritos de aquellos que no pudieron asistir. Se utilizó literatura relevante que sirviera de contexto adicional cuando era necesario
