The term ‘wind energy’ as a system of components that converts the kinetic energy of the wind into electricity or mechanical power, and which comprises all necessary components including energy storage, power conditioning, control systems, and transmission systems, etc.
The total amount of kinetic energy to satisfy all our needs by extracting just one-fourth of the energy from wind.
Limitations of Wind energy
- Their efficiencies are limited to some 50-70% of the Betz limit.
- Wind turbine towers are at most a few hundred feet tall, winds at higher elevations from the ground are not utilized.
- It assumes almost certainly incorrect that there will be no further developments or improvements in wind turbine technology
