ENERGY CONSERVATION
![Page 2: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/2.jpg)
Types of Energy Energy can be broadly divided into two
categories- Renewable Energy Non Renewable Energy
![Page 3: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/3.jpg)
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 world’s 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.
![Page 8: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/8.jpg)
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.
![Page 9: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/9.jpg)
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.
![Page 11: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/11.jpg)
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?
![Page 12: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/12.jpg)
![Page 13: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/13.jpg)
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.
![Page 16: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/16.jpg)
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 youngest can do our bit to
save energy. We should not waste energy in office or at home.
![Page 19: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/19.jpg)
In Office Always switch off lights and fans while
going out of the cabins.
![Page 20: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/20.jpg)
In Office
In computer lab, we should switch off computers before going out of office.
![Page 21: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/21.jpg)
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!)
![Page 22: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/22.jpg)
At Home We should not keep light and fan
unnecessarily switched on.
![Page 23: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/23.jpg)
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.
![Page 24: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/24.jpg)
At Home We should not open fridge door
frequently.
![Page 25: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/25.jpg)
At Home
We should not open fridge door for long time.
![Page 26: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/26.jpg)
At Home
Watching interesting programs on TV is interesting, but afterwards, TV should be switched off.
![Page 27: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/27.jpg)
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.
![Page 28: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/28.jpg)
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….
![Page 29: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/29.jpg)
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.
![Page 30: Energy conservation](https://reader036.vdocument.in/reader036/viewer/2022081413/5491fa57b479590a728b458f/html5/thumbnails/30.jpg)
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.
