What is the significance of ‘energy’? Differentiate between commercial and non-commercial sources of energy.
Energy is the most important component of economic infrastructure. It is a critical aspect of the development process of a nation. It is essential for industries as no commodity is produced without using energy. Nowadays, energy is used even in the agricultural sector. It is needed to operate tube-wells, tractors and thrashers. It is also required in houses for cooking. One cannot even think of a day without electricity and other sources of energy like petrol, LPG, etc. So, we can say that energy is the lifeline of the entire production activity.
