How Long Will An Energy Source Last Us
(i) Fossil fuels (coal, petroleum and natural gas) will get depleted some day as these are exhaustible sources of energy. It has been estimated that coal will last for another 200 years whereas known reservoirs of petroleum for another 60 years and those of natural gas for about 40 years.
(ii) We can get a continuous supply of biomass only if we plant trees in a planned manner. In case, it is not done so, we would fall short of biomass.
(iii) Geothermal energy is an inexhaustible source of energy.
(iv) Nuclear energy is also inexhaustible as only a small mass of uranium produces large amount of energy, e.g., one atom of uranium produces 10 million times the energy produced by the combustion of an atom of carbon from coal.
(v) Solar energy, Water energy, Wind energy and Ocean energy are inexhaustible sources of energy.
