Russian President Vladimir Putin questioned on Tuesday the use of wind power, saying wind turbines were harmful to birds and worms.

Russia, a world-leading producer of fossil fuel, is lagging other countries in its development of renewable energy sources, such as solar and wind-powered energy.

Wind power is rarely used in the country to generate electricity. Enel Russia pledged 90 million euros to build a power generation facility by 2024 with a capacity of 71 megawatts.
