We need to conserve energy resources because of the following reasons: (i) Energy is a basic requirement for economic development. Every sector of national economy—agriculture, industry, transport, commercial and domestic—needs inputs of energy. (ii) There is an urgent need to develop a sustainable path of energy development. (iii) India is presently one of the least energy efficient countries in the world. We have to adopt a cautious approach for judicious use of our limited energy resources. (iv) Various development plans require increasing amount of energy to remain operational. (v) The success of economic development plans depends on energy resources. (vi) Consumption of energy in all forms has been steadily rising all over the country.Therefore, it is necessary to minimise its consumption. We must keep it in mind that our energy resources are limited. (vii) There is an urgent need to develop a sustainable path of energy development.We should promote energy conservation and use of renewable energy resources.
