Wind energy has the lowest environmental impacts of any source of electricity generation

Wind energy has the lowest environmental impacts of any source of electricity generation, with modern wind power plants collectively being far less harmful to birds than radio towers, tall buildings, and numerous other human-made objects.

Regarding reliability and backup, changes in wind energy output occur slowly, since it typically takes hours for a weather event to change the aggregate output of renewable plants that are spread over a large geographic area. Because of this and the fact that wind output can be predicted using weather forecasting while conventional generator outages are unpredictable, grid operators can accommodate wind with slower types of reserve generation that usually cost a fraction of the fast reserves used to accommodate fossil and nuclear plant outages.

So in reality, it is more accurate to talk about needing
