A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.

Natural resources should be used wisely because most of them are exhaustible and cannot be replenished or take million years to replenish. CNG is the cleanest fuel and hence should be used instead of petrol. People should also adopt car pooling to prevent excessive use of fuel and also protect from pollution.

Petrol is a limited resource and can be exhausted if not used wisely. Natural gas is stored under high pressure as CNG. CNG can be used as a fuel instead of petrol as it is less polluting. It is a cleaner fuel. 

In India, the Petroleum Conservation Research Association(PCRA) advises people how to save petrol/diesel while driving. Their tips include driving at a constant and moderate speed as far as possible, switching off the engine at traffic lights or at a place where you have to wait, ensuring correct tyre pressure, ensuring regular maintenance of the vehicle, etc.

Dry cleaning is the procedure of cleaning clothes by using chemical solvents (the substance which can dissolve in other substance ). Petrol is a chemical which is used as a solvent for dry cleaning of clothes.

Natural gas is product of petroleum which is used in the form of compressed natural gas and transported through pipes.
