Refining a Selectively Perceptible Wind Turbine System for Preventing Bat Fatalities

Presenter: Paul Cryan, U.S. Geological Survey


Managing Bird and Bat Turbine Strikes Using Weather Radar

Presenter: Robb Diehl, U.S. Geological Survey


This webinar provided an overview of two research projects by U.S. Geological Survey (USGS) to examine early-stage technologies aimed at minimizing the potential impacts of wind turbines on wildlife. The projects have begun field research at the National Wind Technology Center (NWTC) under NREL’s Technology Development and Innovation (TD&I) program, funded by DOE and supported on-site by NREL staff.

The first project, led by USGS researcher scientist Paul Cryan, explores whether illuminating a turbine with dim ultraviolet (UV) light will prevent bats from approaching and being struck by moving blades. USGS researcher Robb Diehl leads the second project, which considers leveraging the existing U.S. weather radar network, known as Next-Generation Weather Radar (NEXRAD), to provide wind power plant operators with additional information that could be used to manage wind turbines in ways that reduce impacts to wildlife.
