    Explain any three social and economic values which encourage us to use more and more non-conventional sources of energy.

    Answer:

    In India, non-conventional energy sources consist of those energy sources that are infinite, natural, and restorable. For example, tidal energy, solar energy, and wind energy are non-conventional sources of energy. Fascinatingly, the application of tidal energy and wind energy was operational in the form of energy sources long back when mineral oil, coal, and natural gas were not broadly introduced as conventional sources of energy.
                Wind energy is a popular form of non-conventional energy. It is utilized for drawing water, which is an essential requirement in irrigating agricultural lands in the rural areas. In addition, it can be utilized for electricity generation.
                Solar energy is one of the most important non-conventional sources of energy that are utilized in India. The solar cookers are quite economical and they have been a remarkable invention.
                Biomass is an important source of energy which represents approximately 33% of the overall volume of fuel used in the country. The two principal segments of the biomass program are generation and usage of biomass. Smoke-free ambience, improved healthcare, and better quality of life and education are some of the salient benefits of biomass.
