Researchers from Standford University have proved that energy production in wind farms increases once you point turbines slightly away from oncoming wind

Steering wind power in a new direction: Stanford study shows how to improve production at wind farms

On a working wind farm, Stanford researchers have shown that angling turbines slightly away from the wind can boost energy produced overall and even out the otherwise variable supply.

What’s good for one is not always best for all. Solitary wind turbines produce the most power when pointing directly into the wind. But when tightly packed lines of turbines face the wind on wind farms, wakes from upstream generators can interfere with those downstream. Like a speedboat slowed by choppy water from a boat in front, the wake from a wind turbine reduces the output of those behind it. Pointing turbines slightly away from oncoming wind – called wake-steering – can reduce that interference and improve both the quantity and quality of power from wind... ...
