Chapters
Wind turbines generate electricity by capturing the kinetic energy of the wind and converting it into electrical energy. The wind turns the blades, which spin a rotor connected to a generator. Inside the generator, magnets and coils interact to produce an electric current that flows onto the power grid.
  • Wind turbines function similarly to pinwheels with generators.
  • Generators utilize magnets to create electric current (amps).
  • Voltage represents the force of electricity.
  • Wind turbines, hydroelectric dams, steam engines, and nuclear plants all use turbines to generate electricity, but with different power sources.
