Question

Objectives of wind energy and it's application

Answer 1

Wind power is the use of air flow through wind turbines to provide the mechanical power to turn electric generators. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land.

Answer 2

Wind Energy

Air is the basic necessity of life. Man cannot live without air for more than three minutes Air is a mechanical mixture of various gases like oxygen, Nitrogen, Carbon dioxide, water vapour, ozone and other gases. Oxygen is needed by the body for many of vital functions Oxygen, Nitrogen Carbon dioxide water vapour, ozone and other gases. Oxygen is needed by the body for many of its vital functions.

Air is an important natural resource. In order to utilize air as a good resource we have to control the Air Pollution, which is due to industry, thermal power stations, automobiles, and domestic combustion etc. There are always additions of a number of harmful gases to atmosphere. These adversely affect air quality and make it unfit for living organisms.

Moving air is known as wind which produces energy. Like solar energy, wind energy is a very important non-conventional source of energy. In India, the wind power is of great significance as there are large coastal, hill, and desert where wind energy can be carefully exploited for generation of electricity and water pumping. Wind energy may be converted into mechanical and electrical energies. Wind energy in India is generally utilized in wind pumps, wind battery charges, wind electricity generators etc.

:

This energy has been utilized for pumping water in rural areas and may also be useful in remote villages. About 20,000 M.W. electricity can be generated in India from wind. Wind farms and wind mills are installed in different parts of our country.

Application of Wind Energy:

1. The wind energy is used to propel the sailboats in river and seas to transport men and materials from one place to another.

2. Wind energy is used to run pumps to draw water from the grounds through wind mills.

3. Wind energy has also been used to run flourmills to grind the grains like wheat and corn into flour.

:

4. Now-a-days wind energy is being used to generate electricity.

Wind energy may be considered as the world’s fastest growing energy source.

By the development of technology, wind power may become most economical and environmental friendly source of electricity in many countries in the coming 10 to 20 years.
