South Africa’s wind farm uses bird-detection tech and red blades to cut bird deaths while expanding clean energy.
South Africa’s Excelsior Wind Farm uses a "Shutdown on Demand" system to halt turbines when endangered birds like the Cape vulture or black harrier are spotted, reducing bird deaths to fewer than eight in five years with minimal energy loss.
However, the critically endangered black harrier—fewer than 1,300 remain—faces ongoing risks due to its size, detection difficulty, and habitat loss, with 13 deaths recorded in a decade.
A trial painting turbine blades red reduced bird fatalities by 87%, offering a promising solution to balance renewable energy growth with wildlife protection.
