These massive wind farms have the potential to do a great deal of environmental damage all by themselves.

The example I use is wind moving across lake Michigan. As the air moves across the lake in a steady flow it picks up moisture but may not rain over the lake. The rain doesn’t come until the air moves inland and rises over the warmer ground. As the air rises the moisture condenses into rain and falls in a line that matches the shoreline nearly perfectly. If you put up a thousand 300 foot windmills its going to disrupt the airflow and “could” cause serious changes downwind.
