Wind turbines used to obtain wind energy can represent a threat to biodiversity in some areas, since thousands of birds and bats die between their blades every year , especially during migrations such as those that annually fly over the Strait of Gibraltar.
Fortunately, researchers at Loughborough University, in the United Kingdom, have just found a way to avoid it: paint them in colors. They say that since birds look for insects to eat, and that they are attracted to the red or gray color of the turbine blades, painting them in color would reduce the problems . In their experiments, they used blue, red, and purple paint. And they have concluded that this last color is the one that is least attractive to insects. The results have been published in the European Journal of Wildlife Research .
