Answer 2

Answer:

CNG (Compressed Natural Gas)

Explanation:

Delhi is the fourth most polluted city in the world in the list of 41 cities. Burning of fossil fuels like petrol and diesel has increased the air pollution in Delhi. So in 2002, they switched to using a new fuel - CNG (compressed natural gas). It is preferred because CNG is a clean fuel that produces very few unburned particles and is therefore considered environmentally friendly. CNG burns most efficiently, unlike gasoline or diesel, in cars and very little of it remains unburned. Besides, CNG is cheaper than petrol or diesel, thieves cannot siphon it or fake petrol or diesel.

Therefore, CNG (Compressed Natural Gas) has been used in Delhi since 2003.

CNG (Compressed Natural Gas)
