wind turbines

Wind turbines are tall machines with big spinning blades. They are like windmills you might see in a picture, but bigger. Wind turbines take the energy from the wind, and turns it into electricity. This electricity can then be used to power homes and businesses, and help to reduce electricity bills. Wind turbines work by catching the wind in their blades. The blades are shaped like an airplane wing and are designed to capture the most energy from the wind. When the wind blows, the blades spin and turn a shaft inside the turbine. The shaft is connected to a generator, which is a machine that turns the shaft's motion into electricity. The generated electricity is then sent through a power line to a home or a business.
