3. WHAT IS ENERGY ?
 Energy lights our cities, powers our vehicles, and
runs machinery in factories. It warms and cools our
homes, cooks our food, plays our music, and gives
us pictures on television.
 Energy is defined as the ability or the capacity to
do work.

4. TYPES OF ENERGY
 RENEWABLE ENERGY:
Renewable energy can be generated continuously practically
without decay of source.
Some examples are :
• Solar energy , Wind energy , Geothermal energy , Hydro
energy.
NON-RENEWABLE ENERGY:
Non-renewable energy is energy that comes from the ground
and is not replaced in a relatively short amount of time.
e.g. energy generated from combustion of fossil fuels , coal ,
gas etc.

6. Alternate Sources of Energy
Wind Energy
Hydroelectric Energy
Biomass Energy
Solar energy

7. Wind Energy
• Wind energy is the kinetic
energy associated with
the movement of
atmospheric air. It has
been used for hundreds
of years for sailing,
grinding grain, and for
irrigation. Wind energy
systems convert this
kinetic energy to more
useful forms of power.

8. Hydro-electric Energy
• The energy in the flowing
water can be used to
produce electricity. Waves
result from the interaction
of the wind with the surface
of the sea and represent a
transfer of energy from the
wind to the sea. Energy can
be extracted from tides by
creating a reservoir or basin
behind a barrage and then
passing tidal waters through
turbines in the barrage to
generate electricity.

9. Bio-mass energy
• Biomass is a renewable
energy resource derived
from the carbonaceous
waste of various human
and natural activities. It is
derived from numerous
sources, including the by-
products from the timber
industry, agricultural
crops, raw material from
the forest, major parts of
household waste and
wood.

10. Solar Energy
• Solar energy is the most
readily available source of
energy. It does not belong
to anybody and is,
therefore, free. It is also
the most important of the
non-conventional sources
of energy because it is
non-polluting and,
therefore, helps in
lessening the greenhouse
effect.

11. WHY TO CONSERVE IT ?
We have limited resources available on earth.
 Our demands are continuously increasing day
by day.
 It is possible that someday most of the non-
renewable resources will be exhausted and we
will have to switch over to alternate energy

12. We save our money when
we save energy.
We reduce pollution when
we save energy.
We save our energy when
we save energy.

13. WHAT WE CAN DO ?
 RECYCLE - compositing waste materials into new
products to prevent waste of potentially useful
materials.
 Turn off all electronic devices that are not in use. Not
only turn them off but try to remember to unplug
them. You will be surprised how much you will save
with this simple step!
 Replace old light bulbs with energy saving fluorescent
bulbs. They may cost more, but will save you much
more in the long run.

14. At Home
•We should not keep lights
unnecessarily switched on.
• Reduce the energy your
appliances consume by analyzing
star ratings.
• Improve your water heating
efficiency to reduce energy costs.
At Public
Places
• Switch of the fans and lights in
the places like bus terminal and
railway stations when not
necessary.
• Switch off the street lights.
• Big Hoardings, lightened up for
the whole evening and nights are
other wastage of power which
can be and should be avoided

15. ENERGY CONSERVATION
IN INDIA
 About 70% of India's energy generation capacity is from fossil
fuels, with coal accounting for 40% of India's total energy
consumption followed by crude oil and natural gas at 24% and
6% respectively. India is largely dependent on fossil fuel
imports to meet its energy demands.
 By 2030, India's dependence on energy imports is expected
to exceed 53% of the country's total energy consumption. In
2009-10, the country imported 159.26 million tonnes of crude
oil which amount to 80% of its domestic crude oil consumption
and 31% of the country's total imports are oil imports. The
growth of electricity generation in India has been hindered by
domestic coal shortages[ and as a consequence, India's coal
imports for electricity generation increased by 18% in 2010
