Question

What is meant by wind energy farm? Write one of its practical applications. Give any three limitations of using wind energy farm.

Answer 1

Answer:

Number of windmills erected over a large area is known as wind energy farm.

The practical application of a windmill farm is energy output of each windmill in the farm is coupled together to get electricity at a commercial scale.

Limitations of using a wind energy farm

•wind energy farms can be established only in those areas where wind blows for a greater part of the year

•Wind speed should be higher than 15km/hr to maintain the speed of turbine

•There should be some backup facilities like storage cells, to take care of energy needs during a period when there is no wind

Answer 2

Wind energy

Explanation:

A wind farm is place where the energy of the wind is harnessed using windmills in large numbers in order to generate electricity. Modern wind turbines operate together in wind farms to produce electricity for utilities.

The limitations in obtaining energy from the wind are as follows:

1. Wind energy farms can be established only at places where wind blows for major part of year.
2. Wind speed should be minimum 15 Km/h in order to obtain wind energy.
3. Electricity should be stored in batteries for use when wind is not available and hence unable to generate power.
4. Large areas of land is required to establish wind farms.
5. Windmills require high maintenance.
