No activity will occur without energy. INTRODUCTION: -Energy is an essential component/requirement of our daily life. Different forms of energy govern our lives in daily routines Heat energy obtained by burning fuels like wood, coal, kerosene or cooking gas is used to cook food at home. The energy from fuels like petrol and diesel is used to run vehicles. Electrical energy operates bulbs, tubes, fans, radio, television and other household equipment’s. The universe is filled with various sources of energy. We can use this energy by converting it to other useful forms. The current chapter deals with different categories of sources of energy and the related topics. In this universe every moving entity is backed by some amount of energy in one form or other, even biological life is driven and governed by food which is a form of energy. Biological engines on one side consume food as a form of organic energy & in turn induces locomotion in the biological species. But unfortunately, these energy reserves are sooner or later exhausting at a very fast speed. So, lest the world comes abruptly to a standstill continued research quest is going on all around the world either to convert these exhaustible energy resources into non-exhaustible ones or to invent new inexhaustible resources. The aim & objective of this skill enhancement course is: i) to make abreast the students about the research work going on all around the world in this field. ii) and to inculcate the research instinct in the students in this direction while taking due care of environment & the ecological balance.
