Wind Power Over-population
The expansion of wind farms to generate power could reach a point of diminishing returns if too many are placed near each other, new research finds. This is a real threat for coastal areas of Northern Europe, where limited space is seeing the turbines being built in clusters.
Writing in the journal Scientific Reports, researchers say wind speeds up to 60 miles downwind of the farms are significantly slowed down by them under some weather conditions.
This means output from neighbouring wind farms could be reduced up to 25% if they are placed too close together.
