1. ENERGY
CONSERVATION

2. Types of Energy
 Energy can be broadly divided into two
categories-
 Renewable Energy
 Non Renewable Energy

3. Renewable Energy
 Renewable energy can be generated
continuously practically without decay
of source. E.g.-
 Solar Energy
 Wind Energy
 Geothermal Energy
 Hydro Energy

4. Solar Energy
 Solar energy can be converted into
electrical energy by using solar
panels, or alternatively, be used as
thermal energy using solar water
heaters, solar cookers etc.

5. Wind Energy
 India is world’s third largest producer
of electricity generation using wind
power by wind mills.

6. Geothermal Energy
 A lot of energy exists inside earth
crust. Natural hot water springs are a
good source of getting such energy.

7. Hydro Energy
 Using dams, water is allowed to pass
through turbine blades, which
produces electricity. In India, after
coal, most of the energy is produced
by this method.

8. Non Renewable Energy
 Non renewable energy cannot be
generated again and again, e.g.
energy generated from combustion of
fossil fuels, energy from coal and gas
etc.

9. Energy
 Energy can neither be generated nor it
can be destroyed. It can only be
converted from one form to another.
 For example, in a room heater,
electrical energy is converted to the
thermal energy.
 Turbine converts mechanical energy
stored in steam to electrical energy.

10. Why to Conserve?
 We have limited fuels available on
earth.
 Our demand for energy is increasing
day-by-day.
 It is possible that someday, most of
fuels will be exhausted, and we will
have to switch over to alternate
energy.

11. Limited Fuels
 At present consumption levels-
 Crude oil will last only for 40 years.
 Gas will last for 60 years.
 Coal will be finished in nearly 200
years.
 Ever thought of life without oil
and gas?

13. Increasing Consumption
 Furthermore, our consumption is
increasing day-by-day.
 This means fuels will last much earlier
than expected.
 The only solution is …..

14. Energy Conservation

15. Energy Conservation in
India
 In India, government has passed
“Energy Conservation Bill, 2001” for
better utilization of energy and
conservation of the same.
 By this act, it is mandatory for energy
intensive sectors to get their “Energy
Audit” conducted by accredited energy
auditor.

16. Bureau of Energy
Efficiency
 This body keeps watch on energy
consumption patterns, develops norms
for appliances etc.
 It also organizes different competitions
e.g. poster & slogan competition etc.
for children.

17. Star Ratings
 BEE has also initiated “Star Rating
System” for electrical appliances e.g.
refrigerator, CFL, geysers etc.
 In this system, 1-5 stars are allotted to
products depending on their energy
efficiency. A five star product means
that it consumes least energy in its
segment.

18. What Can We Do?
 We, the youngest can do our bit to
save energy. We should not waste
energy in office or at home.

19. In Office
 Always switch off lights and fans while
going out of the cabins.

20. In Office
 In computer lab, we should switch off
computers before going out of office.

21. In School
 If there are less students in the class,
we should sit together so that some
fans can be switched off. (NOT IN
EXAMS!)

22. At Home
 We should not keep light and fan
unnecessarily switched on.

23. At Home
 Tell mother to take material out from
fridge if it is to be heated, some time
earlier so that cooking gas
consumption is low.

24. At Home
 We should not open fridge door
frequently.

25. At Home
 We should not open fridge door for
long time.

26. At Home
 Watching interesting programs on TV
is interesting, but afterwards, TV
should be switched off.

27. At Home
 While going to purchase new
products, e.g. refrigerator, geysers,
CFL etc., we should insist upon
purchasing a five star product rather
than cheap and energy waster
product.

28. How will it help?
 Take an example:
 We replace one 100W bulb with a
13W CFL.
 Let us assume electricity is available
for Rs. 3.00 per unit, and this bulb is
used for 6 Hours a day.
 The annual saving would be….

29. Power Saving
 Power saved: 100W-13W = 87W
=87W X 6 Hours X 365 Days
=17520 WH
=17.520 kWH or Units
=Rs. 52.56
Say Rupees 50 per one bulb replaced.

30. So,
 Remember to replace light bulbs with
CFLs so electricity could be available
for more time.
 You can also ask your parents for a
chocolate or some other gift after
reducing your electricity bill.

31. What Else can be Done?
 We should discuss energy
conservation with our friends and tell
others how can we reduce energy
consumption.
