Electricity is one of the greatest inventions of all times. It is mostly generated by using coal, natural gas and petroleum, which are exhaustable resources. Can you imagine the human society without electricity? This may happen in future, when all energy resources will be exhausted. Explain the values that can change this possible darkness scenario.

Answer:

Mineral fuels like coal, petroleum, natural gas and nuclear energy are the conventional sources of energy. They are exhaustable. Sustainable energy resources are the renewable. These resources can help us in future after taking great care of these resources.

Even then we should kept in mind certain things to avoid such situation:

(i) Creating awareness among the masses about development of sustainable sources of energy.

(ii) Maximum use of renwable energy resources such as solar, wind, biomass and hydroelectricity.

(iv) Optimum use of energy resources and minimum wastage.

(v) Alternative energy sources like solar power, wind, wav, geothermal etc. are to be developed.
