Wind farms provide green energy. However, wind-turbine blades kill thousands of birds. Researchers have an answer. Painting one blade black helps birds see the blades. This cut bird deaths by 70 per cent. A researcher said bird deaths was "one of the main environmental concerns related to wind energy".
Researchers tried to make wind turbines safer. They painted one blade of four turbines black. The turbines with one black blade reduced bird deaths. A bird protection group was happy. It said wind farms must be "in harmony with nature". It added: "We find the right places for them." It said they should not harm wildlife.
