2. What is Energy ?
 The ability to do work.
 Energy cannot be created nor destroyed, only changed.
 Energy will always transfer from high to low.
 No energy transfer is 100% efficient.

3.  The sources of energy can be classified in two ways:
1) Renewable energy.
2) Non-renewable energy.
 Renewable energy:-
 Renewable is obtained from source
that are not exhaustible.they can be continuously used. These
energy sources are also called non-conventional energy sources.
 Non- Renewable energy:-
 Non renewable energy is
obatined from conventional fossil fuels(coals,oil,gas,etc).these have
in use for several decades. They cannot be used continuously
therefore, these sources are also called exhuastible source of
energy.

4. RENEWABLE ENERGYSOURCES
 Solar Energy
 Biomass
 Hydel Energy
 Wind Energy
 Tidal Energy
 Geo-thermal Energy

5. 1.SOLAR ENERGY
Solar energy is the energy obtained from sun in the form of
radiations. Sun is an inexhaustible source of energy and
pollution free source of energy. It results as a result of Nuclear
Fusion reactions,
Solar Energy has the maximum potential of all the sources of
renewable energy.
Sun gives 1000 times more energy than we need.

6.  ADVANTAGES OF SOLAR ENERGY
Easy Installation & maintenance.
Absence of noise and other form of pollution.
Longer life , makes it favorable for remote, isolated, forest, hilly
areas.

7.  DIS-ADVANTAGES OF SOLAR
ENERGY
Uncertainty of availability of solar energy due to cloud, wind
rainfall etc.
Large spaces are required for collection of solar energy at a
useful rate.
Currently the initial cost is high but is reducing at a faster rate.

8. 2. BIOMASS ENERGY
Biomass is the organic material which has stored sunlight in the
form of chemical energy
Biomass include, wood, bio-fuel, and biogas
Bio-energy is generated when biomass is burned.

9.  ADVANTAGES OF BIOMASS
ENERGY
Plants ensures a continuous supply of energy due to their
continuous growth.
Potential for rural areas.
Biogas can be used for cooking purpose.
Waste can be used as an excellent fertilizers.

10. DIS-ADVANTAGES OF BIOMASS
ENERGY
• Except biogas production, the other biomass energy sources
have to be established a significant role.
•
• Availability is limited.

11. 3.WIND
ENERGY
Wind energy is the kinetic energy associated with the movement
of air It has been used hundreds of years for sailing, grinding.
Wind turbine transforms the energy in the wind into mechanical
energy which is in turn converted into electrical energy through
generators.
The minimum wind speed which is required for the satisfactory
performance of wind generator is 15 km/hr . The wind power
potential of India is estimated to be about 20,000 MW, while at
present we are generating about 1020 MW.

12.  ADVANTAGES OF WIND
ENERGY
Non polluting and environment friendly source of energy.
Important renewable and sustainable source of energy, available
free of cost.
Generation of electricity is fast.
Cheaper as compared to other sources

13.  DIS-ADVANTAGES OF WIND
ENERGY
Favorable in geographic locations which are always away from
cities.
Variable, unsteady, irregular, intermittent, erratic,
and dangerous
Can be located only in vast open areas.
Economical only on a small scale

14. 4. HYDROPOWER
ENERGY
The energy in the form of flowing water can be used to produce
electricity. Hydropower can be generated using water collected
and stored at high elevation and led through a tunnel or pipe line
to a turbine located at low level.
The minimum height of water fall must be 10 m
Hydroelectric power generation capacity of India is 27010 MW.

15.  ADVANTAGES OF HYDRO POWER
ENERGY
Longer life
Minimum operating staff.
Non Polluting and hence environmental friendly.
Low cost of generation & maintenance.

16.  DIS-ADVANTAGES OF HYDRO POWER
ENERGY
Hydro- Power project takes long time for clearance.
Rehabilitation and resettlement of displaced people is a major
problem associated to any hydropower project.
Large scale initial investment is required.
• .

17. 5. TIDAL ENERGY
Another form of energy related to local geological conditions is
tidal flow. As water flow In the form of tides from higher level to
lower level it can be used to generate electricity. The tidal energy
can be harnessed by constructing a tidal barrage. During high
tides the sea water flows into the reservoir of the barrage and
turns the turbine, which in turn produces electricity. During low
tides when the sea level is low, the sea water stored in the
barrage flow out into the sea and turns the turbine.

18.  ADVANTAGES OF TIDAL POWER
ENERGY
Can be a Source of Energy for Coastal Cities.
No raw material is required.
Generation is cheaper.

19.  DIS-ADVANTAGES OF TIDAL POWER
ENERGY
Availability is for limited duration and varies
with time and location
Generation capacity is less.
Operational difficulties during bad weather.

20. 6.GEOTHERMAL
ENERGY
Geothermal Energy means heat from the earth. The Earth’s Core
with temperature as high as 60,000 0C is a molten mass
possessing vast amount of energy. This energy sometimes breaks
through the earth and produce Volcanoes.
The steam is then used to power electric generators

21.  ADVANTAGES OF GEOTHERMAL
ENERGY
It is an inexhaustible energy resource.
It is very cheap.
It is good for the hilly, remote area, where no
other source of energy is available.

22.  DIS-ADVANTAGES OF GEOTHERMAL
ENERGY
• These hot springs are generally away from the
areas having potentials of industrial
development.
• The stream energy is to be used as it cannot be
carried out for a longer distance due to loss of
energy and due to the cost factor also.

23. NON RENEWABLE ENERGY
SOURCES
Fossil Fuels:
Fossil fuels such as coal , oil and natural
gas all of which are mixture of compounds
containing carbon and hydrogen. These are
formed by the decomposition of the remains
of plants and animals buried under the earth.
Millions of years ago.

24. NUCLEAR ENERGY
Nuclear Energy is the energy trapped inside the atom. Nuclear
energy can be generated by two types of reactions
Nuclear Fission:
An Atom nucleus can be split apart this is known as fission when
this is done a tremendous amount of energy in the form of both
heat and light is released this energy can be harnessed to
generate electricity.

25. It’s production cost per unit of power is much
lesser than the thermal power production.
Heat generation in the nuclear power plant is
much higher than the heat generation in any
thermal power plant of same size.
 ADVANTAGES OF NUCLEAR
ENERGY

26.  DIS-ADVANTAGES OF
NUCLEAR ENERGY
The high technology required to generate
nuclear power is not available in all the
countries
The nuclear waste are radioactive in nature
and so are harmful to the living beings.

27.  APPLICATONS OF RENEWABLE
ENERGY
 Wind, solar, biomass, biofuels, hydropower
and geothermal energy sources are all
renewable, which means the Earth or sun
are continually producing or replacing
them.
 According to the U.S. Energy Information
Administration, two increasingly used
renewable energy sources are wind and
biofuels.

28.  APPLICATONS OF NON-RENEWABLE
ENERGY
Non renewable energy is that form of
energy which is subject to deletion. This
type of energy is of many uses to us.
It can be used to produce electricity,
heating, cooking, transportation and
manufacturing. 85% of the energy used
in the industrial processes is form the
non-renewable type of energy.

29. CONCLUSION
ENERGY SOURCES are everywhere
and efficiencies are vastly improving
 Simply look at solar efficiencies
Most of the world’s energy in the future
will be generated using energy sources
like solar energy,wind power etc..
