Coal, oil and natural gas are fossil fuels. They have been in existence for a very very long time. Many people use these fuels as a type of energy. However, fossil fuels are non-renewable; if these are used up completely they will never be available again. It is therefore important to conserve fossil fuels. We can do so by using alternative ways of energy.

Fuel is a substance which is used to produce heat energy through chemical reaction. Without it, today no machine is going to be work. All are depend on this to run. Even from a small screw to a big generator there is a need of it. But today, our India is facing a severe fuel crisis. 
                    In our day to day life, it is also a basic need of us.Most countries have to import fuel to meet their needs by spending high amount today. We can say this by seeing the nearest petrol bunks.If we saw them we can find there a long queues of vehicles because there was no fuel to tank up on. It's our time situation about fuel. 
It's really makes our life tough if we still continue the usage of fuel in large amounts. In order to avoid this, We have to bring awareness on people.
                                Fuels like petrol and diesel are also not clean fuels. They cause pollution and increase C02 emissions. So we have to stop using fuel highly which is responsible for causing Global Warming.
                                                             We have to turn of our vehicles at traffic. We have to encourage car pooling and have to minimise the usage of applying brakes. We have to use hybrid cars which run both on gas and electricity. Electric cars like the Indian Reva are good choices. Under-inflated tires reduce fuel efficiency. Travelling the least distances by walk or using bicycle is good for health and helps for fuel conservation too.
