Question

What are the limitations in obtaining energy from wind?

Answer 1

1. We cannot depend upon wind energy as it is available only when air is in motion. The appliances or machines operating with wind energy stop working as soon as the wind stops. The minimum speed of the wind to operate a generator to produce electricity is about 1515 km/h. As soon as the speed of the wind becomes less than 1515 km/h, the generator stops working.
2. There are certain regions where the wind is not available, so the use of wind energy is limited to certain places where the wind is in plenty and blows most of the time.
3. Wind energy is not sufficient to operate very heavy machines.
4. Wind energy cannot be used to operate all types of machines.
5. Windmills are usually broken during storms and hence lot of money is spent on the maintenance of a wind energy form.
