New planning guidelines for wind turbines that are located on biodiversity sites published by the European Commission. In the context of sustainable development, what is more important: renewable energy or biodiversity loss? At first glance the two don't seem mutually exclusive, but they can be in the case of wind turbines. That's why over the years legislation has been put into place to make sure that things like 'bird collision' are avoided.
