Wind power is a renewable energy source that harnesses the energy of moving air to generate electricity. Wind turbines, which are tall structures with large blades, capture the wind's kinetic energy and convert it into mechanical energy. This mechanical energy is then transformed into electrical energy, providing power for homes and businesses. Wind power is considered environmentally friendly because it produces no greenhouse gas emissions during operation. It is a sustainable alternative to fossil fuels, helping to reduce reliance on non-renewable energy sources. As technology advances, wind energy continues to grow as a significant contributor to the global energy mix.
