Question

what is wind energy? explain in detailed

Answer 1

energy possessed by moving air called wind energy......Wind mills are the best example for this.....It is easily available.....Renewable and do not pollute environment...... ☺☺

Answer 2

principle of transformation of energy

converting mechanical energy into electrical energy using the wind blade.

procedure

when the wind blade rotates according to the direction of wind, the rotation of this blade tends to convert the mechanical energy into electrical energy and this energy is stored in a load at the bottom of the windmill... this is to hold mechanism of the wind energy in a simple words..

advantages of wind energy

*this wind energy is a non conventional source of energy thereby can produce for centuries if proper technologies are used
*this extraction of energy is most beneficial in hilly areas

disadvantages of wind energy

*the wind blades are very heavy and expensive
*these energy can be only extracted in hilly areas and not possible in any other plains
*there should be a certain speed of wind to produce this wind energy and that should be a backup for producing electrical energy
*Metals used in this windmill also destroyed and damaged by the natural agents like wind, moisture and make it rusted ..

Denmark is known for wind energy production...

hope that picture helps you...
