Question
By the end of 2002 the public transport of Delhi switched over to a new fuel. Name the fuel. Why is this fuel considered better? Explain.
Solution
Delhi had been categorized as the fourth most polluted city of the world in a list of 41 cities. Burning of fossil fuels has added to the pollution of air in Delhi. So, in year 2002 it switched over to new fuel - CNG (COMPRESSED NATURAL GAS). It is considered better due to following reasons
• CNG is a clean fuel that produces very little unburnt particles and thus it is considered as eco friendly.
• CNG burns most efficiently, unlike petrol or diesel, in the automobiles and very little of it is left unburnt.
• Moreover, CNG is cheaper than petrol or diesel, cannot be siphoned off by thieves and adulterated like petrol or diesel.
