Shadow Flicker is the effect that is produced when the rotating blades of a wind turbine pass by the sun. Some people find this effect of wind turbines particularly bothersome.
In the case of the proposed wind turbine, shadow flicker would occur only about 20 hours per year, and would never last more than a half hour at any one time. It would be confined to the hours around dawn and dusk and would primarily occur over the water, not near residential dwellings.
If residents are annoyed by this phenomenon, there is an easy solution. The turbine can be turned off during the 20 hours annually when shadow flicker occurs.
