    3.7 Wind Generators: There are three main parts in horizontal axis wind turbines: (1) a rotor‚ (2) an alternator‚ and (3) a tail. The rotor blades are attached to a central hub covered by a nose cone that improves aerodynamics. Three blades are generally present in upwind generators. This entire assembly rotates when wind blows past the blades‚ hence the name “rotor.” In many small wind turbines the rotor is coupled to a shaft which is coupled to an alternator‚ a device that produces AC electricity

    Wind Energy A turbine is machine that spins arounds catching energy that’s passing by. The huge rotor blades (propellers) on the front of a wind turbine are the "turbine" part. As wind passes by‚ the kinetic energy (energy of movement) it contains makes the blades spin around (usually quite slowly). The blades have a special curved shape so they capture as much energy from the wind as possible. Although we talk about "wind turbines‚" the turbine is only one of the three main
