No, wind energy is a non-conventional, or unconventional source of energy. Conventional sources of energy are coal, oil, natural gas and uranium.
wind
There is no absolute hard and fast definition. But I would say coal, oil, and natural gas, and hydro are conventional. Wind, solar, tidal, and biomass non-conventional. I'm not sure about nuclear.
Conventional energy source - Gasoline and other petroleum products like diesel etc. They are derived from Coal and fossil fuels. Non - Conventional energy source - Solar Power, Wind energy (Using wind mills), hydro - electricity, Bio Gas etc.
This is difficult to decide I think. It has been available for 50 years now - does that make it conventional? It is a well established and reliable energy source.
Currently, human's conventional source of energy is fossil fuel.
non conventional
You don't. There is no difference in the type of energy, between the "conventional" and "non-conventional" types. What makes energy conventional or non-conventional is the SOURCE - a conventional source being one that has been used for a long time.
Yes, wind is a source of energy.
a wind
Wind energy is a renewable resource, as there will always be wind.
No, wind is a renewable energy source. The wind will always be blowing!
