3. INTRODUCTION
Energy
Energy is capacity to do work . Energy can be
changed from one form to another but it neither
be created nor be destroyed.

4. CLASSIFICATION

5. RENEWABLE ENERGY RESOURCES
• The sources of
energy which are renewed again to again
at a faster rate in nature are known as
renewable energy resources. Example –
Solar Energy , Wind Energy ,
Hydro Energy ,Biomass Energy.

6. RENEWABLE ENERGY RESOURSES
SOLAR ENERGY
• Solar energy is available in large amount,
because ultimate sources of energy in an
ecosystem is sun . Thus considered major
future sources of energy .
it is incident on green plants , they
carry out photosynthesis in the presence
of CO2 , water and sunlight and make
their own food
,thus maintain life . Their death produces
biomass . Example – Solar light

8. Photovoltaic cell
is phenomenon
that conversion of
solar energy to
electricity.
Photovoltaic cell

9. HYDRO ENERGY
• Water is made to fall from height to rotate
turbine, which help generate
electricity ,is known as hydro
energy.
APPLICATION
Hydro power use the energy for moving water for
a
variety of
generate
s
useful application ,
hydroelectricity electricity
by the gravitational force of
falling water . It use water in dams to drive
turbines and generates which turns Mechanical
energy into Electrical energy.

11. WIND ENERGY
• Wind is allowed to rotate the blades of wind
mills , which rotates turbines to generate
electricity.
APPLICATION
• The wind is a free clean and in exhaustible
energy sources . It has served human kind well
for many centuries by propelling ships and
driving ,wind turbines to grind grain and pump
water .
• DENMARK was the first country to use wind for

13. BIOMASS
• India is an agriculture based country
.Agriculture and dairy farming produced
large amount of biomass.
Example – Agricultural waste and Cow
Dung
• Dead organicmatter or dead plant and
animal partsare known as
Biomass.
Example- wood, leaf parts and crop
residue .

15. NON RENEWABLE ENERGY
earth crust at very high
temperature
• Theseenergy resources are formed inside the
and
pressure ,take a very long passage of time in
their formation .Thus they are present in
limited amount in nature’s reservoir.
Example – coal , petroleum , natural gas ,
timber , nuclear fuel. These included two
types of energy resources - Fossil fuel,
Nuclear Energy.

16. FOSSIL FUEL
• Fossil fuel are found inside the earth crust
where they have formed through heat and
compression of forest waste and other organic
matter, which got buried due to Earthquake
and landslide etc. CLASSIFICATION OF
FOSSIL FUEL
Solid ( Coal )
Liquid (
Petroleum )
Gaseous ( Natural gas )

17. COAL
• Co
al
is the
most
abundantly
foun
d fossil fuel in the
world
.It contain Carbon ,
Water , Sulphur , and
Nitrogen . Coal
meets 70% of the
total energy needs
of the world around.
It is used for cooking
, industry, and
thermal power plant.

18. PETROLEUM
• Petroleum is a natural
underground fossil
energy resources . It is
formed due to
decomposition of micro
plankton deposited
upon the sea beds,
lakes , and river for
millions of years . The
decomposition takes
place by the action of
bacteria under lack of
O2 , called crude oil .

19. NATURAL GAS
• It is a mixture
hydrocarbon gases
trapped under the earth
surface. It is a mainly
consisting of methane
(CH4)
,Propane (C3H8) , and
Butane (C4H10) .
• Natural gas can used in
two different forms -
LPG – ( Liquefied Petroleum Gas
) CNG – (Compressed Natural

20. NUCLEAR ENERGY
• It present nuclear power . It is a highly
developed alternative far energy
production in place of coal.
Nuclear energy can divided by two
processes - NUCLEAR FISSION
NUCLEAR FUSION

21. NUCLEAR FISSION
• The heavy nucleus
on
bombardmen
t
with
neutron splits into
lighter nuclei (Barium
and krypton ) releases
large amount of
energy .one amu of
U235 yield energy
equal to burning of 15
metric tons of coal.

22. NUCLEAR FUSION
• Nuclear fusion is a
reaction in which two or
more atomic nuclei
come close enough to
form one or more
different atomic nuclei
and subatomic particles
(neutrons and / or
protons ) .The difference
in mass between the
products and reactants
is manifested as the
release of large
amounts of energy.

23. IMPORTANCE IN INDIA
• In India there are still thousand of villages
where darkness is not dispelled by
electricity . These villages due to their
remote location are not likely to have
access to electricity supply

grown
Early
human had modest energy requirement.
Most ly food and fuel for fires to cook and
keep warm . In today’s society human
consume as much as 110 times as energy
per person as early humans . In any event
the exploitation of all energy sources
ultimately rely on material on planet earth.
