How does a wind mill generate electric energy ?
potential energy of wind- rotation of wind mill- electrical energy
kinetic energy of wind- rotation of wind mill- electrical energy
solar energy- rotation of wind mill- electrical energy
sea breeze and land breeze- rotation of wind mill- electrical energy
Kinetic energy of wind is used to rotate the wind mill which rotates the turbine and hence the dynamo generates electricity.
what causes the wind to blow? what is the minimum wind velocity required to obtain useful energy with a wind mill? Electricity generated by a wind mill is another form of solar energy. Explain.
Select the correct statements from the following.
(i) Wind energy is renewable source of energy.
(ii) Installation cost of wind mill is low.
(iii) Wind mills are generally installed in populated areas.
(iv) Energy produced from wind mills is non-polluting.
