How does wind power electricity?

• The wind pushes free electrons through the air then into wires.

• Wind pushes the connected blades to push spinning parts then activate a generator to make electricity.

• Water flows through the blades of the turbine and causes generator to make electricity.

• Puppies play with the blades and stimulate the generator in body of the turbine.
