What is meant by the term energy: - Energy can be defined as the ability of a body to do
work. 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.

SOURCES OF ENERGY: A source of energy is the one which can provide an adequate
amount of energy in suitable form over a long period of time. Characteristics of a good
source of energy. A good source of energy should have the following characteristics:
(i) lt should supply enough amount of useful energy.
(ii) lt should be easily stored and should occupy less space for storage.
(iii) lt should be easily transported.
(iv) it should be economical.
(v) lt should be easily available and accessible
(vi) lt should cause minimum environmental pollution.
Sources of energy are categorized in two types - renewable and non- renewable
sources of energy.
Sources of energy which are being produced continuously in nature and are inexhaustible
as these can be used again & again endlessly, are called renewable sources of energy. Some
of the renewable sources of energy are listed as follows: (a)Solar energy (b) Wind energy
(c) Hydro energy (energy from flowing water) (d) Bio-fuels (wood, bio-gas and alcohol)
(e) Hydrogen (f) Energy from oceans (tidal energy, sea wave energy etc.) (g) Geothermal
energy
(a) Solar Energy:
The Sun is the ultimate source of many forms of energy available on earth. The energy
obtained from the sun is called solar energy. Solar energy is the result of nuclear fusion
reactions taking place inside the sun. The solar energy trapped by land and water bodies at
the earth causes many phenomena in nature like winds, storms; rain, snowfall, sea-waves
etc. and the plants utilize solar energy to prepare food by the process of photosynthesis.
SOLAR CONSTANT: The solar energy reaching unit area per second at outer edge of
earth's atmosphere exposed perpendicularly to the rays of the sun at the average distance
between the sun and the earth is known as 'solar constant' and its value is approximately
1400 W/m2 (1.4 kilojoules per second per square meter). Solar energy received by Earth
in given time is given by: Solar constant x area x time
Composition of Sun's Energy (i) Earth's surface receives three types of electromagnetic
waves: ultra-violet rays, visible rays and infrared rays. all having different range of
wavelengths ln spectrum of solar radiations, the rays which have wavelength range
