Welfare of Wild Animals in Renewable Energy Infrastructure Zones

Wind turbines, solar farms, and transmission lines cause wildlife mortality and habitat disruption that require careful siting and design to minimize, particularly for birds and bats.

Key Facts

Wind turbines kill an estimated 140,000-500,000 birds and 600,000-900,000 bats annually in the US
Solar farm glare attracts aquatic insects and birds that mistake panels for water bodies — the lake effect
Transmission lines cause electrocution of large birds including eagles and raptors at rates of thousands annually
Curtailment of turbines during peak migration periods reduces bat mortality by 70-90% at minimal energy cost
Underground cabling and bird-safe pole design dramatically reduce bird electrocution from power infrastructure

Welfare Considerations

Renewable energy is essential for addressing climate change, which is itself one of the largest drivers of wildlife welfare harm. Yet renewable infrastructure causes real and significant welfare costs to birds and bats that deserve attention and mitigation. The good news is that most major sources of renewable energy wildlife mortality have known technical solutions: turbine curtailment for bats, underground cabling for bird electrocution, careful siting away from migration routes. Mitigation is achievable; what it requires is design commitment and regulatory standards.

What You Can Do

Support renewable energy development that includes wildlife impact assessment and mitigation requirements
Advocate for mandatory turbine curtailment during peak bat migration periods
Raise awareness of bird-safe power line design in infrastructure planning processes
Donate to organizations that monitor and advocate for wildlife-safe renewable energy siting and design
