What effects do wind turbines have on wildlife such as birds or terrestrial animals?

Hi John,

The wind energy industry is committed to protecting wildlife and the environment by siting wind farms with respect for habitats. The industry partners with academic leaders, researchers, regulators and wildlife organizations to ensure development of wind energy is respectful and responsible.

Some examples include Bird Studies Canada (BSC), Bats and Wind Energy Cooperative (BWEC) and the American Wind and Wildlife Institute (AWWI.) Not to mention, wind energy is virtually emission-free and does not contribute to climate change, which is the single biggest threat to wildlife.

Recent data from studies suggest that wind farms are a minor source of bird mortality relative to other human impacts and other sources of electricity production, and the wind industry continues to monitor and research emerging issues and to take steps to further mitigate losses – the wind energy industry is held to high standards by regulatory authorities. If you’re interested in finding out more on this study, online reports can be found on the following websites:
