2. INTRODUCTION
• Minerals are the most important natural
resources.
• A compound of naturally available substance with
specific chemical composition is called a mineral.
• Iron ore, manganese ore, bauxite ore mica and
gold are most important.
• Energy sources like petroleum, coal, and atomic
minerals are also produced in our country.
• Non-conventional source of energy is also very
important now-a-days.

29. Power Resources

30. Coal
• In India the most
important power
resource is coal.
• India ranks 3rd in
the world in the
production of
coal.

31. • Millions of years ago the earth was covered
with thick dense forests and these forests
gradually buried in the layers of the earth and
converted into coal due to heat and pressure.

32. Other uses of coal
To manufacture
Insect
repellent,
explosives,
artificial rubber,
plastic,
chemical
fertilizers

33. We call coal as ‘Black Diamond’.
Why?

34. States and areas
Damodar river valley
Jharkhand and
Chattisgarh produce
largest amount of coal
Godavari, Mahanadi,
Vardha river valleys
Oddisha
West Bengal
Andhra Pradesh
Madhya Pradesh

35. Petroleum
• Petroleum is the product of fossils of ancient
living beings.
• Petroleum is called Crude oil because when it
is pumped out of the earth it is a mixture of
various materials.
• It is refined in refineries to produce gasoline,
petrol, diesel, kerosene, etc.
• It is a raw material for many industries.

36. Liquid Gold
• It is a very important energy source in
agriculture, industry and transportation.
• This is very precious in both during peace and
war.
• Hence it is called Liquid Gold

37. Petroleum was first discovered at Digboi, Assam
Till independence Digboi was the only region of
petroleum products

38. Oil deposits in India
Assam
Lakhimpur, Hugrijin, Moran
Naharakathia.

Ankaleshwar.
• In 1974, crude oil was
identified about 110 kms away
from Bombay in the off shore
field called Bombay High and
production started in 1976.
• Oil deposits have been
discovered in Kaveri, Krishna,
Godavari and Mahanadi river
basins.

42. Atomic minerals
• Atomic energy is generated using it.
• Atomic power decides the status and might of
the nation.
• Atomic power was used only for a country’s
defense in the earlier days.
• It is being widely used for power generation.

43. Uranium

Jharkhand, in the loamy soil of Saharanapur of UP and the
sandy soils of Kerala containing monazite

44. Thorium
This can be found in Kerala, Bihar, Tamil Nadu and Rajasthan

45. Beryllium
Beryllium oxide is used as a catalyst or moderator in reactors
producing nuclear energy. India has sufficient deposits of
beryllium.

46. Lithium
This light metal is obtained from lepidolite and fudomine
ores. It is found abundantly in Jharkhand and Madhya
Pradesh.

47. NON-CONVENTIONAL ENERGY
SOURCES

48. Global warming
• All over the world due to the use of
conventional energy sources like coal,
petroleum, natural gas and oter fossil fuels,
phenomenon of green-house effect and
consequent increase in temperature of the
earth’s atmosphere is being noticed.
• This is called global warming.

49. How can we reduce this global
warming?

50. Non conventional energy sources
• Solar energy
• Wind energy
• Tidal energy
• Geo thermal energy
• Bio-gas

51. Solar energy
• Use of the heat emanating from the sun’s rays is
called ‘Solar Energy’.
• Solar energy is used in solar water heater, cooker,
solar thermal electric bulb, railway signal,
transport and communication media.
• India’s first solar electricity production centre is
being proposed to be set up at Baramar in
Rajasthan.
• A solar electric station was proposed to be set up
in Chikkaballapur in Karnataka.

53. Wind Power
• In India Wind power is being produced on a
commercial purposes and in the future, manu
parts of the country would be using wind
power as the main source of electricity.
• India is the fifth country in the world to
produce wind energy.
• Tamil Nadu, Maharashtra, Karnataka, Rajastan
and Gujarat are establishing power stations.

54. Wind Power

56. Need for non conventional energy
• In India of the energy resources being used
the exhaustible energy resources are the main
ones.
• It has become inevitable to use non-
conventional energy sources to conserve the
conventional energy sources.
• Exploration and use of nonexhaustible energy
uses has gained a lot of importance in the five-
year plans.

57. Remedies
• It has become inevitable in our country to take
necessary steps to prevent the deficit in the
energy resources.
1. Use of non conventional resources.
2. Giving importance to hydroelectric power
generation.
3. Use of alternate local energy resources
4. Encouraging the use of non-conventional energy
resources.
5. Educating the people regarding the reduced use of
energy resources.
6. Producing energy from solid waste.

58. Answer the following questions
• What are the uses of Manganese?
• How was mica used a lot in the past? Why is
its use very less?
• How is coal formed?
• Why is petroleum known as liquid gold?
• What is global warming?
• What are the uses of solar energy?
