<human>:  How do wind turbines work?
<bot>: Wind turbines use the kinetic energy of the wind to generate electricity. The turbines have three blades connected to a rotor, which spins a shaft connected to a generator. The generator creates a current of electricity that is fed into the power grid and then distributed to homes and businesses. The rotors of the turbine face into the wind, and the blades, which can be up to 80 meters long, capture the energy of the wind and convert it into mechanical power. The mechanical power then drives the generator, which converts it into electrical energy. This electricity is distributed through a power grid across the country and then used to power our homes, offices, and businesses.
