4. Introduction
• Energy may be defined as the stored capacity to
work.
• It is an essential requirement for all activities on
earth.
• It is the key to development.
• In fact, the amount of energy production &
consumption is considered to be an index of a
country’s economic development.
5. Evolution of Energy Use
• Initially human beings used the somatic energy which was
the energy that they derived from their body to do work.
This was obtained from the food they ingested and the
efficiency of their body system.
• Amount of somatic energy used by an individual is
measured in terms of Human Energy Equivalent (HEE)
• As human civilisation progressed and developed, human
beings started harnessing the energy that resided outside
their body. This was the extra-somatic energy.
6. • The first somatic source of energy discovered by humans was
fire which they used for cooking food, keeping themselves
warn and for protection against wild animals.
• Later they began to use fire to extract metals from ores and
make tools.
• With the help of tools they began to practice agriculture.
• They also tamed animals to harness their muscle power for
agricultural tasks.
• Later on humans started harnessing the energy of water and
wind, coal & petroleum.
• The mid 18th century witnessed the start of the Industrial
revolution which was based on the use of coal as a source of
power.
7. • The beginning of the 19th century saw the modern use of
petroleum as an energy resource.
• In the second half of the 20th century, with the evolution of
the consumeristic society, the use of electricity which was a
secondary source of energy increased.
• At present several non-traditional sources of energy like
solar, wave, tidal, geothermal, nuclear, biomass, bio gas, etc
have come into play.
• Increase in industrialisation, urbanisation, transportation &
industrial agriculture has led to a continuous increase in
energy consumption.

Other Renewables
In 2019, out of the total primary energy consumption in the world about
12% came from renewable sources (hydroelectricity & other renewables)
and the remaining 88% came from non-renewable sources
17. • Coal is a combustible rock which
had its origin in the accumulation
and partial decomposition of
vegetation. Coal is composed
primarily of carbon (60-90%),
hydrogen (1-12%), oxygen (2-20%),
nitrogen (1-3%) and slight
amounts of sulphur and phosphorus.
• With the advancement of
coalification process which begins
with plant material the proportion
of these elements progressively
varies. The carbon content steadily
increases and hydrogen, oxygen
content decreases.

18. Origin of Coal:
• Most coal deposits of the world are of Carboniferous period
i.e. about 300 million years old.
• More recent deposits of Tertiary period are usually composed
of lignite or brown coal and peat which represent an early
stage of coal formation and is still being formed today.
• Coal originated in swampy deltaic areas with a hot and wet
climate which encouraged luxuriant growth of plants.
• When the plants died their vegetative remains accumulated
on the swampy surface.
19. • Subsequent deposition of mud or sand sealed this vegetative
matter and prevented its total decomposition and
disappearance.
• These vegetative remains consolidated between other rock
strata were altered by the combined effect of microbial
action, pressure and heat over a considerable period and
ultimately turned into coal deposits.
• Therefore coal is also called a fossil fuel.
20. Significance of Coal:
• Coal is a primary source of energy. The credit of first world
wide use of coal in modern times can be attributed to the
beginning of industrial revolution in England in 18th
century.
• With the knowledge of immense heat potential in coal, its
wide use in many industries was encouraged. The invention
of steam locomotive for running trains by Stephenson in
1814 provided permanency to the coal mining industry.
• At present coal is used in producing thermal electricity. It is
used both as a source of power and raw material in iron and
steel industry.
21. • It is also used in the production of coal gas, tar, coke, etc.
Different types of varnish and germicides are also produced
from it.
• Because of its multi – faceted use and economic value it is
rightly termed as ‘Black Diamond’.
22. Types of Coal
• There are four types of coal on
the basis of rank ( i.e., degree
of coalification ) viz. Peat ,
Lignite , Bituminous and
Anthracite.
• These types are actually four
stages in coal formation.
Peat
Lignite
Bituminous
Anthracite

24. (i) Peat – Peat is a fibrous brown substance formed by the
partly decayed organic remains in swamps and bogs. It
represents the first stage in coal formation and has a high
percentage of moisture and volatile matter. Carbon constitutes
only about one-third of its bulk and it has a low heating
capacity.
(ii) Lignite or Brown coal – Regarded as the second stage of
coal formation lignite is soft and still retains much of its
brownish woody appearance but it is more compact than peat.
However, its moisture content is over 35% and it gives more
smoke than heat.
25. (iii) Bituminous – The hard, black, compact bituminous coal makes
up almost 80% of the world’s total coal out-put. Its carbon content
varies from 40% to 80% and its moisture and volatile content varies
from 15% to 40%. It is often sub-divided into several minor divisions
such as sub-bituminous ( the poorer type ) and bituminous coals.
Bituminous coal is widely used for industrial purpose. It is also known
as coking coal.
(iv) Anthracite – This is the hardest and the best quality coal
possessing very high carbon content. It is shiny and lustrous, almost
jet black and is so completely compressed that it shows no banded
structure. It has a carbon content of almost 95% and has practically
no volatile matter. It does not ignite easily but once ignited it gives
out a great amount of heat.
26. Problems associated with the usage of coal:
➢ Coal is very heavy and bulky so it is difficult and expensive to
transport it over long distances.
➢ The burning of coal generates harmful gases such as carbon
dioxide, carbon monoxide, sulphur dioxide, etc. which
pollutes the environment.
➢ Burning of coal produces ash and smoke. The disposal of ash
become a problem.

32. Coal Production in India:
• The Indian coal fields are divided into two categories, i.e.
(i)the Gondwana coal fields and (ii)Tertiary coal fields
• The Gondwana coal fields belong to the Carboniferous period
and they account for 98% of the total reserves and 99% of
the production of coal in India.
• The Gondwana coal fields are situated in the Peninsular
region and occur down in the valleys of certain rivers, viz.
the Damodar (Jharkhand-West Bengal), the Mahanadi
(Chhattisgarh-Odisha), the Son (Madhya Pradesh-Bihar),
the Godavari and Wardha (Maharashtra –AndhraPradesh-
Telangana), the Indravati, the Narmada, the Koel, the
Pench, the Kanhan, etc.
33. • The Tertiary coal fields belong to a younger age from 15-60
million years and are mainly confined to the extra-
peninsular region.
• Important areas of Tertiary coal includes parts of Assam,
Meghalaya, Arunachal Pradesh, Nagaland, Himalayan
foothills of Darjeeling in West Bengal, Jammu-Kashmir,
Rajasthan, Kerala, Tamil Nadu and UT of Puducherry.
• Most of the coal belonging to Gondwana coal fields are of
bituminous grade while the coal of Tertiary coal fields are of
a lower grade (lignite).

• Telangana – Coal fields in the state are located in the
Godavari valley.
• Maharashtra – Most of the coal fields are found in Chanda-
Wardha valley.
• West Bengal – The most important coal field is Ranigunj
which is the oldest coal filed in the country.
38. • The word petroleum is
derived from the Latin
words ‘petra,, meaning rock
and ‘oleum’, meaning oil.
• Thus, the literal meaning of
petroleum is ‘rock oil’. It is
so called because it is
derived from the rocks,
where it flows freely in
liquid state.
39. • Technically speaking, petroleum is an inflammable mixture of
oily hydrocarbons with very complex chemical properties.
History of the Use of Petroleum:
• The use of petroleum first began where seepages occurred at
the surface.
• In ancient times the Chinese, who encountered oil in drilling
for salt in brine wells, used it as fuel to evaporate the brine.
40. • The Egyptians used it for embalming the dead before burial.
• The Bible notes that dark pitch from petroleum residues was
used on Noah’s ark to make the wooden vessel waterproof.
• It was also recorded that tar (bitumen) was employed in
cementing bricks in the construction of the Towns of
Babylon and paving the streets in Mesopotamia.
• Petroleum was also mentioned by many Greek & Roman
writers who noted its use as lamp fuel and for ointments.
• In many other parts of the world such as around the
Caspian sea, in Romania, in Myanmar and in India, oil was
often used in lighting, cooking, lubricating and for medical
purposes.
41. • But the modern commercial use of oil started only in the
19th century.
• It is believed that it was an American Samuel M. Kier who
first found petroleum by chance in 1848 in wells on the
banks of the Alleghany river of Pennsylvania.
• He named it as Seneca oil after the local Indians.
• The shortage of whale oil, then widely used for domestic
lighting and for oiling machinery, created a great demand
for petroleum or mineral oil.
42. • Soon, a company by the name of Seneca Oil Company was
formed for drilling the oil.
• In August, 1859 oil was struck and its production started.
• This ushered in the great ‘oil rush’ and commercial
exploitation of petroleum began on a large scale.
43. Origin & Occurrence of Petroleum:
• It is generally presumed that petroleum is derived from
organic material and so it is also called a fossil fuel.
• It is formed from the decomposition by anaerobic bacteria of
innumerable small marine plant and animal organisms
trapped in sediments as they were deposited on the sea-bed.
• Some scientists believe that when an accumulation of
sedimentary rocks in the ocean depths is compacted, the
pressure generates heat which transforms the decaying
matter into tiny droplets of petroleum.
44. • Others think that petroleum may have formed relatively
rapidly after the organisms were trapped in the sediments
and that heat and pressure were not necessary to the
process.
• Petroleum formation in the sedimentary rocks has been
going on since the beginning of appearance of life and is
continuing even today.

45. Advantage of Petroleum over Coal :
• Compared to coal the calorific value of petroleum is much
higher.
• Petroleum doesn’t gives out smoke and ash after burning.
• It can be easily transported over long distances through
pipelines and oil tankers.
• It has the widest range of domestic as well as industrial uses.
It is therefore, often referred to as ‘liquid gold’.
46. Use of Petroleum :
• For heating homes & hearths particularly in the cold regions
• As industrial power to drive engines and for heating furnaces
and producing thermal electricity
• As transport power for driving railways, motor cars, ships
and aeroplanes
• As lubricants of machines especially high speed machines
• As raw material in various petro-chemical industries, such as
–synthetic rubber, synthetic fibre, fertilisers, medicines, etc.

53. Petroleum Production in India:
• The position of India is quite dismal as far as production of
petroleum is concerned. In 2019, India ranked 23rd in the
list of petroleum producing countries in the world.
• First exploration for petroleum was undertaken in 1866 in
Upper Assam.
• Oil was discovered in 1890 in Digboi area.
• Assam was the only producer of petroleum in India till
1959.
• In 1958 the Khambhat oil fields was discovered and the first
well (Vasundhara) was drilled in Ankaleshwar in 1960.
54. • At present, commercial exploitation of petroleum is carried
out in four regions :
(i) The North-east region extending over the Upper Assam
Valley, Arunachal Pradesh and Nagaland
(ii) Gujarat region extending over the Khambhat basin and
Gujarat plain
(iii) the Mumbai High off-shore region &
(iv) the East coastal region encompassing the Kaveri and
Krishna-Godavari basins.
55. (i) North-Eastern Region
The well known oil fields of this region are Digboi, Naharkatiya,
Moran, Rudrasagar, Galeki and Hugrijan. Digboi is the oldest
oil field in India. In Tirap district of Arunachal Pradesh there is
Nigru oil filed. In the nearby Nagaland, oil fileds are at
Borholla, close to Nagaland-Assam border.
(ii) Gujarat Region
Important oil fields of this region are Ankleshwar, Kalol,
Nawagam, Kosamba, Kathana, Barkol, Mehsana, Sanand &
Lunej. Oil has also been found on the Aliabet island situated 45
km west of Bhavnagar in Saurashtra.
56. (iii) Mumbai High
It is an off-shore oil field located in the Arabian sea 176 km
North-west of Mumbai. At present it is the most important oil
field in the country. The oil & natural gas is brought to Uran
on the mainland through sub-marine pipelines. Another oil
field Bassein has been discovered south of Mumbai High.
(iv) East-coastal Region
It extends over the Kaveri & Krishna-Godavari basins. In the
off-shore area of the Kaveri basin important oil fields are
Narimanam and Kovilappal.
• Petroleum has also been found in Jaisalmer district of
Rajasthan.

58. • Natural gas is a mixture of
gaseous hydrocarbons, of
which methane alone may
take up 80 to 90%.
• The other gases include
ethane, propane & butane.
• Traces of non-hydrocarbon
gases may also occur in it
including helium, nitrogen,
carbon dioxide and
hydrogen sulphide.
NATURAL GAS

59. • Natural gas may occur in association with petroleum, in the
uppermost part of an oil trap or it may occur alone.
• The larger natural gas are often not associated with
petroleum.
Origin of Natural Gas:
• The natural gas originates with the same process as
petroleum.
• The tiny marine organisms which get trapped between
layers of sediments get decomposed by anaerobic bacteria
and give out gas in the process which accumulates as natural
gas.
60. Use of Natural Gas :
• It is widely used as fuel in industries and domestic cooking.
• Petro-chemical industries use natural gas as fuel & raw
material.
• Chemical industries such as artificial rubber, plastics,
fertilisers, ink, carbon, etc. use it as raw material.
• Sometimes it is also used for artificial lighting.
61. Advantage of Natural Gas:
• It has the highest calorific value amongst the fossil fuels.
• Can easily be transported or distributed to long distances
through pipelines.
• Doesn’t leaves any residue after burning.

68. Natural Gas Production in India:
• The production of natural gas in India is at a dismal state. In
2019 the country ranked 31st in the production of natural
gas in the world.
• Natural gas is being obtained from Cauveri off-shore, Nada
in Cambay basin and Tanot in Jaisalmer district in
Rajasthan.
• Oil/gas structures have also been discovered in
Adiyakkamangalam in Tamil Nadu, Andada in Gujarat,
Khovaghat in Assam, Lingal in Andhra Pradesh, Mumbai
off-shore & Kuchchh off-shore.
69. • Discovery of huge reserves of natural gas by Reliance Industries
ltd. In Krishna-Godavari basin off, the coast of Andhra Pradesh is
significant.
• Natural gas production in 2016-17, up to December 2016 was
about 23.884 Billion Cubic Metre. Out of this about 78% was
done by ONGC & OIL and the remaining 22% production was
done by Private / JV companies.
• The share of off-shore natural gas production was about 69.3% in
2016-17. The remaining production came from ten states, viz.
Assam (9.8%), Gujarat (4.8%), Tripura (4.4%), Rajasthan (4.1%),
Tamil Nadu (3.0%), Andhra Pradesh (2.7%), Arunachal Pradesh
(0.1%), Jharkhand (0.01%), Jharkhand (0.01%), Madhya Pradesh
(0.02%) & West Bengal (1.7%).

70. • Nuclear energy is the
energy obtained by altering
the structure of atoms.
• When such an alteration is
made, a large amount of
energy is released in the
form of heat and this is
used to generate electric
power.
• There are two processes
through which the atomic
structure can be altered –
(i)Nuclear Fission &
(ii)Nuclear Fusion
71. • Nuclear Fission – In this case the nucleus of an atom of a
heavy element such as uranium is split in two to release
energy. This process is used in the atomic bomb and in
nuclear power stations.

72. • Nuclear Fusion – In this process the nuclei of two light atoms
such as those of hydrogen, are fused together to form a new
composite nucleus, at the same time releasing energy. The
sun emits light & energy through nuclear fusion. Fusion is
used in the hydrogen bomb, but the reaction is not yet
sufficiently susceptible to human control for it to be used
safely in power stations.

73. Process of Nuclear Power Generation:
• Nuclear fission takes place in a nuclear reactor which consists
of a heat-producing core and a cooling system.
• Within the core, atoms of the fuel usually uranium, enriched
uranium or plutonium are split.
• To spilt the atomic nuclei for nuclear fission neutrons are
bombarded into uranium.
• As neutrons bombard the atoms and split their nuclei, they
split off more neutrons which further bombard other nuclei,
thus, creating a chain reaction.
74. • Fission takes place at a very high temperatures and the
reactor is surrounded by a cooling system through which
water or gases such as carbon dioxide circulates.
• The heat released by the reactor is used to generate steam
and the steam is used to generate electricity.
75. Advantages of Nuclear Energy:
• It is considered to be a clean energy resource as its
generation and use do not emit any carbon dioxide or other
green house gases.
• The amount of fuel required in a nuclear power plant is
much smaller compared to other type of fuel based power
plants. It is estimated that the amount of energy released in
a nuclear fission reaction is ten million times greater than
the amount released in burnin a fossil fuel atom (eg-oil &
gas). Thus, these plants have very low fuel costs.
• These power stations have a very long life.
76. Disadvantages of Nuclear Energy :
• Waste is radioactive and its safe disposal is difficult and
expensive
• Local thermal pollution may be caused from waste water.
• Large scale accidents can be catastrophic, for example – the
Chernobyl accident
• Cost of building and safely decommissioning a nuclear pplant
is very high.
• Requires a high level of technical & scientific knowledge
which is not easily available in developing countries.
77. Production of Nuclear Energy:
• In 2018, nuclear plants supplied 2563 TWh of electricity.
• Twelve countries in 2018 produced at least one-quarter of their
electricity from nuclear.
• France gets around three-quarters of its electricity from nuclear
energy, Hungary, Slovakia and Ukraine get more than half from
nuclear, whilst Belgium, Sweden, Slovenia, Bulgaria, Switzerland,
Finland and Czech Republic get one-third or more.
• South Korea normally gets more than 30% of its electricity from
nuclear, while in the USA, UK, Spain, Romania and Russia about one-
fifth of electricity is from nuclear.
• Japan is used to relying on nuclear power for more than one-quarter
of its electricity and is expected to return to somewhere near that
level.

79. Nuclear Energy Scenario in India:
• Bhabha Atomic Research Centre (BARC) Trombay at Mumbai in
Maharashtra is one of the major centres of research and
development of nuclear power in India.
• There are 6 Atomic Power Plants in the country –
(i) Tarapur near Mumbai in Maharashtra
(ii) Rawatbhata near Kota in Rajasthan
(iii)Kalpakkam in Tamil Nadu
(iv) Narora in Uttar Pradesh
(v) Kaiga in Karnataka
(vi) Kakarapara in Gujarat
80. Atomic Fuel Producing Centres:
• Uranium ore occurs in Jaduguda in Jharkhand. Uranium
corporation of India is responsible for its mining. This natural
ore is processed and enriched at Nuclear Fuel Complex in
Andhra Pradesh.
• Heavy water required as coolant and moderator is produced
at – Kota in Rajasthan, Baroda in Gujarat, Nangal in
Punjab & Tuticorin in Kerala
• India still has to go a long way as far as nuclear energy is
concerned.
