ENERGY
CONSERVATION
Types of Energy
 Energy can be broadly divided into two
categories-
 Renewable Energy
 Non Renewable Energy
Renewable Energy
 Renewable energy can be generated
continuously practically without decay
of source. E.g.-
 Solar Energy
 Wind Energy
 Geothermal Energy
 Hydro Energy
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.
Wind Energy
 India is worlds third largest producer
of electricity generation using wind
power by wind mills.
Geothermal Energy
 A lot of energy exists inside earth
crust. Natural hot water springs are a
good source of getting such energy.
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.
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.
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.
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.
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?

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

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.
What Can We Do?
 We, the children can do our bit to save
energy. We should not waste energy in
school or at home.
In School
 Always switch off lights and fans while
going out of the class.
In School
 In computer lab, we should switch off
computers before going out of class.
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!)
At Home
 We should not keep light and fan
unnecessarily switched on.
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.
At Home
 Watching interesting programs on TV
is interesting, but afterwards, TV
should be switched off.
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.
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.
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.
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.
What Else can be Done?
 We should discuss energy
conservation with our friends and tell
others how can we reduce energy
consumption.
