Wind energy and birds’ death

  • India added 3.5-gigawatt (GW) wind energy capacity in early 2025, marking 82 percent growth and raising total capacity to 51.3 GW.
  • A Wildlife Institute of India (WII) study in Jaisalmer, Rajasthan, found 124 bird carcasses near 90 turbines across seven surveys in a 3,000 square kilometre area.
  • The estimated annual bird mortality was 4,464 birds per 1,000 square kilometre after adjusting for detection errors and scavenging.
  • No carcasses were found at control sites, confirming wind turbines as the main cause of deaths, especially affecting raptors.
  • The Experts suggested the mitigation through blade painting, seasonal turbine shutdowns and site selection using the Avian Sensitivity Tool for Energy Planning (AVISTEP).
  • AVISTEP, developed by Birdlife International, helps identify areas of low to very high avian sensitivity for safer project planning.
  • India plans 30 GW offshore wind capacity by 2030 with 4 GW bids launched in Gujarat and Tamil Nadu.
