How do you harness the Wind Energy?
To harness the stored energy of blowing wind one must use Wind Turbines. Wind turbines are not new to Europe in that in most parts these in the form of wind mills have been in use for centuries. The modern version of wind turbine incorporate;
- Multi Blade Rotor (propeller) which converts the kinetic energy of the wind to rotary motion
- An Electricity Generator
- A two or multi sped gear box with flexible couplings
- A tower of adequate height
- Electrical cabling, switch gear and controls
The Rotational movement of the turbine blades is transmitted to the Alternator (Generator) shaft through the gear box. The rotation of the alternator rotor generates electricity which is proportional to the wind speed and the rotational velocity of the turbine.
