What is Wind Energy?
Wind Energy Facts
Wind energy is valued because it is a
clean source of energy and causes minimum pollution
- Fact 1: Wind power consists of turning energy from the wind to other energy forms.
- Fact 2: Windmills have been in use since 2000 B.C. and were first developed in Persia and China.
- Fact 3: Wind energy is underutilized as of now and holds tremendous potential for the future.
- Fact 4: Wind turbines can get as high as 20 story buildings and have three blades which are 60 meter long.
Wind energy is mostly harnessed by wind turbines which are as high as 20 story buildings and have three blades which are 60 meter long.
They resemble giant propellers of airplanes mounted on a stick. The blades are spun by the wind which transfers motion to a shaft connected to a generator which produces electricity.
The largest turbines can harness energy to power 600 American homes. These turbines form wind farms and hundreds are arranged in lines in windy spots like a ridge. A small turbine in the back yard can easily power a small business or a home.
A wind farm is a collection of wind turbines in the same location. Many wind farms provide rental income to rural communities where they are situated. Wind energy is valued because it is a clean source of energy and causes minimum pollution. Operational costs are minimal after the erection of turbines. Mass production and advances in technology are making turbines cheaper than never before. Wind energy is also receiving subsidies and benefits from governments keen to popularize this clean source of energy.
