(ii) Every sector of the national economy -agriculture, industry, transport, commercial and domestic-needs inputs of energy.

(iii) The implementation of economic developmental plans require increasing amounts of energy.

(iv) The consumption of energy in all forms has been steadily rising and hence there is an urgent need to develop a sustainable path of energy development.
