Non Conventional Source of Energy
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 sources of energy include coal, oil, natural gas, hydropower, and wood. Photos of these sources of energy are widely available on the Internet.
geo thermal
Currently, human's conventional source of energy is fossil fuel.
No, wind energy is a non-conventional, or unconventional source of energy. Conventional sources of energy are coal, oil, natural gas and uranium.
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.
no clue seriously

non conventional energy = renewable energy http://en.wikipedia.org/wiki/Renewable_energy
