What is the significance of shadow flicker around wind farms?
Shadow flicker is commonly understood to be a rare effect of the sun shining on the blades of a wind turbine causing a shadow that may be cast at certain times of the day in certain seasons. In terms of shadow flicker, analysis undertaken on wind farm sites in Ontario and elsewhere have shown that shadow flicker at homes can occur, but for a very small percentage of the time (approximately 0.5 percent of daytime hours). InterWind studies potential shadow flicker effects of wind turbines and develops wind farms in a fashion that minimizes such effects.
