We use energy for

many purposes in

our daily life.

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

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

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:

It is calculated that sun’s energy would last for more than 1 billion years

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

•Wind energy:

Wind power is used from early days for grinding of grains and

pumping out water

Wind power is extracted from air flow using wind

turbines. The net effects of environment are generally less problematic than non-

renewable resources

Hydropower energy:

Hydropower energy is generated by potential energy stored by dams. It is cheap, clean and very efficient.

Bio-diesel:

Bio-diesel are best alternative fuel to existing combustion engines.

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

Always use front load washing machine because top load washing machine use high amount of electricity and water

Switch old incandescent bulbs into CFL and LED bulbs

Convert your old electronic appliances to newer ones to save energy. Because older appliances designs are not meant for saving energy

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

Clean AC’s air filters to improve efficiency of cooling and to improve air flow

For travelling short distances don’t use vehicles, go by walk or cycle.

Always check your vehicle tire pressure as it can also contribute to the use of petrol

Always drive vehicles with the speed limit of 45-60kmph to save fuel

Servicing your vehicle at regular intervals will lessen the amount of fuel used by engine and make your vehicle run smoothly.

Always try your level best to use public transportation, avoid private transportation at all costs

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

Heat insulate your house’s doors and windows to keeping your house’s temperature low and to save electricity

Plug out electric appliances which is not in use

SAVE ELECTRICITY!SAVE WORLD!

If we work hard with determination we can create a green earth
