  1. Wind EngineeringSocietal and Environmental FactorsModule 7.1 Avian Issues Lakshmi N. Sankar lsankar@ae.gatech.edu

  2. Overview • Wind energy is renewable and environment friendly, and helps reduce emissions (COx, NOx, Sulfur, Mercury,…). • Adverse effects have also been reported. • These include • Avian fatalities • Power Quality • Noise • This module deals with Avian issues. • Modules 7.2 deals with Power Quality. • Module 7.3 deals with wind turbine noise.

  3. Alaska • The next few slides are from http://www.alaska.edu/uaf/cem/ine/aetdl/conferences/2008Presentations/BirdIssueswWindTurbines.A.Stickney.pdf

  4. Siting the Wind Turbine should address Avian Issues

  5. Some Species are Protected

  6. Other Studies

  7. NWCC Study Estimates of Annual Mortalities Netherlands: 37 fatalities per turbine per year, due to proximity to coastal regions.

  8. NWCC Data

  9. NREL/SR-500-26092 • A Population Study of Golden Eagles in the Altamont Pass Wind Resource Area: • Population Trend Analysis 1994–1997

  10. Conclusions and Recommendations • Avian fatality due to collisions with wind turbines is, in general, extremely small compared to other causes of fatality. • Siting appears to play a significant role (e.g. Netherlands, Altamont Pass in CA), however. • Any study on wind turbine siting should include avian issues. • Visibility a factor – painting the blade surface with contrast may help. • Noise makers have been proposed. • Lattice structures attract perching birds. Tubular structures less inviting.
