The fossil fuels like coal, oil and natural gas cannot remain the dominant sources of energy forever.
Whatever the precise timetable for their depletion, oil and gas supplies will not keep up with growing energy demands.
Coal is available in abundance, but its use exacerbates air and water pollution problems, and coal contributes even more
substantially than the other fossil fuels to the buildup of carbon dioxide in the atmosphere.
For a long-term, sustainable energy source, solar power offers an attractive alternative energy in India. It is environmentally clean, and its energy is transmitted from the sun to the Earth free of charge and there is no outcome any toxic gases.
