Environmental Issues Wind power means we don't have to burn more fossil fuels. One 15 MW wind farm would save some 500,000 barrels of oil per year. Wind power means we don't have to dam any more rivers and flood any more habitat. Wind power is pretty benign. There used to be concerns about bird collisions but these have largely been resolved.
Noise levels are low, lower than wind noises in nearby trees or ocean surf.
The biggest impact is visual, but these are not unattactive structures.
