We use energy for
many purposes in
our daily life.
![Page 4: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/4.jpg)
In today’s world nothing
will happen without energy.
Energy is the basic needs.

But we are continuously exploiting our natural resources resulting in
shortage of natural energy resources
![Page 6: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/6.jpg)
IT IS AN SHOCKING FACT THAT THE EXISTING COAL SUPPLY ONLY LAST FOR 145 YEARS, OIL SUPPLY FOR 38 YEARS AND NATURAL
GAS FOR 61 YEARS

Now this is an high time to convert into renewable resources
![Page 8: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/8.jpg)
Why we had to change into renewable energy resources?
Because, if we continuously use these existing resources then it will lead to severe shortages and crisis of electricity and petroleum

Types of renewable energy resources:• Solar energy:
![Page 11: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/11.jpg)
It is calculated that sun’s energy would last for more than 1 billion years
![Page 12: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/12.jpg)
Sun’ s energy can be easily harvested using photovoltaic electric cell. The setting up of solar cells may be costly but it will be effective
![Page 13: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/13.jpg)
•Wind energy:
![Page 14: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/14.jpg)
Wind power is used from early days for grinding of grains and
pumping out water
![Page 15: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/15.jpg)
Wind power is extracted from air flow using wind
turbines. The net effects of environment are generally less problematic than non-
renewable resources
![Page 16: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/16.jpg)
Hydropower energy:
![Page 17: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/17.jpg)
Hydropower energy is generated by potential energy stored by dams. It is cheap, clean and very efficient.
![Page 18: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/18.jpg)
Bio-diesel:
![Page 19: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/19.jpg)
Bio-diesel are best alternative fuel to existing combustion engines.
![Page 20: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/20.jpg)
Bio-diesel is a clean and efficient fuel and does not emit any green house gases.

We students can conserve energy by adopting simple techniques
Switch OFF electrical appliances which are working wastely
![Page 22: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/22.jpg)
Always use front load washing machine because top load washing machine use high amount of electricity and water
![Page 23: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/23.jpg)
Switch old incandescent bulbs into CFL and LED bulbs
![Page 24: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/24.jpg)
Convert your old electronic appliances to newer ones to save energy. Because older appliances designs are not meant for saving energy
![Page 25: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/25.jpg)
Air conditioners should be operated at a temperature of 20 degrees in winter and 26 degrees in summer to save energy and to enjoy optimum cooling performance
![Page 26: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/26.jpg)
Clean AC’s air filters to improve efficiency of cooling and to improve air flow
![Page 27: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/27.jpg)
For travelling short distances don’t use vehicles, go by walk or cycle.
![Page 28: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/28.jpg)
Always check your vehicle tire pressure as it can also contribute to the use of petrol
![Page 29: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/29.jpg)
Always drive vehicles with the speed limit of 45-60kmph to save fuel
![Page 30: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/30.jpg)
Servicing your vehicle at regular intervals will lessen the amount of fuel used by engine and make your vehicle run smoothly.
![Page 31: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/31.jpg)
Always try your level best to use public transportation, avoid private transportation at all costs
![Page 32: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/32.jpg)
Don’t leave your fridge door open frequently, because it will cause heat gain and the fridge had to draw more power to keep its cooling
![Page 33: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/33.jpg)
Heat insulate your house’s doors and windows to keeping your house’s temperature low and to save electricity
![Page 34: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/34.jpg)
Plug out electric appliances which is not in use
![Page 35: Conservation of energy](https://reader037.vdocuments.site/reader037/viewer/2022103119/55cf03aabb61ebbb078b4813/html5/thumbnails/35.jpg)
SAVE ELECTRICITY!SAVE WORLD!
If we work hard with determination we can create a green earth
