How is electricity generated using wind?

Every day, wind turbines capture the wind''s power and convert it into electricity. It''s a fairly simple process: When the wind blows the turbine''s blades spin, capturing energy – this energy is then sent through a gearbox to a generator, which converts it into electricity for the grid with a special device called an inverter.
