Renewable Sources Of Energy: Those sources of encrgy, whlch are renewable in nature, are called renewable sources of energy. The renewable sources are generally pollution-free. Solar energy, hydel energy, wind energy, tidal energy, etc. are renewable sources of eergy. Those sources of energy whose formation takes millions of years and which are limited in supply are called non-renewable sources of energy, Non-renewable sources create heavy pollution. Coal, petroleum, natural gas, etc. are non-renewable sources of energy.
The advantage of such classilication of energy pources is that it helpa us to decide about the combervaubn of avnilable encrgy Bources for future generation. It also helps us in development of alternative soarces of cnergy accelerating the scope for the development of appropriate technology
Renewable Sources - Wind Energy: Sun's energy is the main factor responsible for the movement of air. Moving air is called wind and lt possesses kinctic energy. Windmills, invented 250 years ago by Persians, are once again gaining popularity. Modern windmills convert wind energy into either mechanical energy or electrical energy. A windmill consists of a fan-like structure mounted at some height on a strong support. Its blades are so designed that when wind strikes them, a pressure difference is created between them. This difference produces a turning effect and makes them rotate.
The height of the windmill, the number of blades and their shape, etc. are decided on the basis of average wind velocity and local environmental factors. The rotational motion of the windmill is utilised to obtain mechanical work like in a water-lifting pump. If a turbine is connected to the windmill, electricity can be generated but the electricity generated by one windmill cannot be used commercially. To generate a large amount of electricity, a wind energy farm is established where there are several windmills erected in a large area. In Gujarat, wind-energy farms are located at following places: Lamba near Porbandar, Okha, Mandavi and Dhank. The largest wind farm in India is near Kanyakumari in Tamil Nadu and it generates 300 MW of electricity. The greatest advantage of wind-energy farms is that the electricity is generated from a renewable source and it is pollution-free.
Limitations:
(i) Wind energy farms can be established only at places with continuous flow of wind.
(ii) The average wind velocity should be 16 km/h to enable its working.
(iii) It requires a large area of land and cost of installation is very high.
(iv) It creates noise pollution.
