The intention here seems to be to make it sound as though wind turbines are not a significant risk to birds. While it's technically correct that some other threats kill more birds than wind turbines do, this argument is in some ways misleading, and in other ways irrelevant. To understand why, let's take a look at the numbers.“The problem is the cost of building such a grid,” says Janusz Bialek, director of the Centre for Energy Systems at Skoltech Institute of Science and Technology.
Offshore wind farms are hitting the headlines across the globe for their sheer scale - and as countries increasingly turn to them to decrease their dependency on energy from Russia as well as speed up their energy transition.

Wind turbines have three main parts: Tower: Built on a sturdy foundation, a wind turbine’s tower may stand well above 100 feet tall. At that height the wind is likely stronger and more consistent, since it is not being deflected by trees and buildings. Also, the height prevents the blades from being a danger to livestock or other animals.
