Question

Find out why CNG (compressed natural gas) is preferred as a fuel over diesel.

a) Lower emissions
b) Cost-effectiveness
c) Renewable source
d) All of the above

Answer 1

CNG is preferred over diesel as a fuel due to lower emissions, cost-effectiveness, and the renewable source it can be derived from.

Step-by-step explanation:

CNG (compressed natural gas) is preferred as a fuel over diesel for several reasons:

1. Lower emissions: When CNG is burned, it produces fewer emissions compared to diesel. This includes lower levels of carbon dioxide (CO2), nitrogen oxides (NOx), particulate matter, and sulfur compounds. This makes CNG a cleaner and more environmentally friendly choice.
2. Cost-effectiveness: CNG is often cheaper than diesel fuel. This is because natural gas is more abundant and easier to extract compared to crude oil, which is used to produce diesel fuel. Additionally, the infrastructure for distributing natural gas is often more developed, reducing transportation costs.
3. Renewable source: While natural gas is a fossil fuel, it is considered a cleaner and more sustainable option compared to diesel. Natural gas can be sourced from renewable sources like biomethane, which is produced from organic waste materials. This renewable aspect adds to the overall environmental benefits of using CNG.

Therefore, all of the above options (a) Lower emissions, (b) Cost-effectiveness, and (c) Renewable source contribute to why CNG is preferred as a fuel over diesel.
