Lyndsey Ward discusses bird and bat collisions with wind turbines (letters July 8th) and I will expand on that. In 2016 Exeter University published a study suggesting that 80,000 bats annually are killed by UK turbines extrapolating to two million globally.
A Stanford 2016 study suggests that 4.1 birds per magawatt are killed by US turbines extrapolating to 2.1 million globally.
In 2019 a University of Crete suggested 84 Griffon vultures would be killed annually out of a population of a thousand if the wind farms for the island were to be built.
Are wind farms really green?
