Remove turbine lighting to reduce bat and insect attraction
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
Lights placed on wind turbines may attract insects and foraging bats, increasing the risk of collision. However, one study in the USA found fewer bat fatalities at turbines lit with flashing red aviation lights than at unlit turbines (Bennett & Hale 2014), and three other studies in the USA found no difference (Johnson et al. 2004, Jain et al. 2010, Baerwald & Barclay 2011).
