Industries conserve energy to reduce costs and increase profits. Common areas of high energy usage are electricity, labor, and materials

The document provides information on techniques for energy conservation in industries. It defines energy conservation as decreasing energy usage while maintaining output. Key points include:

- Industries conserve energy to reduce costs and increase profits. Common areas of high energy usage are electricity, labor, and materials.

- Common equipment like motors, pumps, compressors, lighting offer significant savings potential through efficiency improvements, proper sizing, maintenance and technology upgrades.

- Proper energy management includes regular audits, monitoring consumption, identifying waste, and implementing cost-effective conservation opportunities.

- Renewable energy options like solar, wind and biomass are also discussed as ways to reduce industries' environmental impacts.

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.
For details, please visit:

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 children can do our bit to save
energy. We should not waste energy in
school or at home.

19. In School
Always switch off lights and fans while
going out of the class.

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

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.
