Fossil fuels are non-renewable source of energy, because if they are exhausted, it cannot be regenerated in a short time. This is because of the fact that, the fossil fuels which we use today, took millions of years to be formed. The fossil fuels are being fast depleted. To overcome this depletion, we have to conserve energy.

We can follow the following simple rules to conserve energy:

(i) Switch off lights and fans when not in use.

(ii) Use solar cookers, heaters, dryers wherever possible.

(iii) Use tube lights which consumes less energy instead of incandescent lamp wherever possible.

(vi) Use efficient home appliances and fuel efficient stove.
