Energy Efficiency | Green Buildings and Infrastructure
We have already discussed how Energy Efficiency can be achieved in different structures. In the previous article, our main focus was on Bio-climatic architecture. Bio-climatic Architecture forms a part of the Principles of Green Building Architecture.
It is necessary to understand the relationship between Bio-climatic Architectural Design and the way in which the Wind energy is harnessed.
We have already discussed the use of Wind turbines for the generation of electricity. We will be discussing the mechanism of Wind turbines in detail.
Wind Turbines
Wind Turbine is a rotary devices which utilizes mechanical energy and converts it into electrical energy. Windmills that extract the energy from the wind and utilize the mechanical energy for cutting of lumber, pumping water etc have been used since ancient times.
Windmills came into picture in 200BC. They have first been used in Persia and then a better and practical version of the windmills has been observed in Sistan, a region between Afghanistan and Iran in the 7th century.
Later on, after the industrial revolution, the concept of using the wind power with the help of wind turbines to generate electricity was discovered.
If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind turbine generator (WTG), wind power unit (WPU), wind energy converter (WEC), or aerogenerator.
