A wind turbine is a device that converts the kinetic energy of wind into mechanical energy, which can then be transformed into electricity. It consists of large blades mounted on a tall tower. When the wind blows, the blades spin, turning a rotor connected to a generator that produces electrical power.
Wind turbines are commonly used in wind farms, where multiple turbines are grouped together to generate electricity on a larger scale. They are considered a renewable energy source because they harness natural wind currents, helping to reduce reliance on fossil fuels and lower greenhouse gas emissions.
