The use of diesel and petrol as fuels in automobiles is being replaced by which of the following fuel?

Compressed Natural Gas (Gas)

The correct answer is option 2. Compressed Natural Gas (Gas).

The replacement of traditional fuels like diesel and petrol with alternative fuels such as Compressed Natural Gas (CNG) is driven by environmental and economic considerations. Here's an explanation of why CNG is being adopted as an alternative fuel in automobiles:

1. Environmental Benefits:

CNG is considered a cleaner-burning fuel compared to diesel and petrol. It produces lower levels of pollutants such as carbon dioxide (CO2), nitrogen oxides (NOx), and particulate matter, contributing to reduced air pollution and lower greenhouse gas emissions.

2. Economic Considerations:

CNG is often more cost-effective than traditional fuels. It is generally less expensive on a per-unit energy basis, making it an attractive option for both consumers and fleet operators.

3. Abundant Natural Gas Reserves:

Natural gas, which is the primary component of CNG, is abundant and widely available. This helps in diversifying the energy sources for transportation and reduces dependence on conventional fossil fuels.

4. Energy Security:

Using CNG helps enhance energy security by diversifying the energy mix in the transportation sector. Reducing reliance on imported oil contributes to greater energy independence for countries.

5. Reduced Greenhouse Gas Emissions:

CNG combustion produces fewer greenhouse gas emissions compared to conventional fuels, contributing to efforts to mitigate climate change.

6. Lower Maintenance Costs:

CNG engines generally have lower maintenance costs compared to diesel engines. The combustion characteristics of CNG result in cleaner engine components and extended maintenance intervals.

7. Government Policies and Incentives:

Many governments around the world are promoting the use of alternative fuels, including CNG, to address environmental concerns and reduce dependence on fossil fuels. Policy measures and incentives, such as tax benefits and subsidies, encourage the adoption of CNG vehicles.

Compressed Natural Gas is commonly used in various types of vehicles, including cars, buses, and trucks. The availability of CNG infrastructure, such as refueling stations, is a key factor influencing the widespread adoption of CNG as a fuel for transportation.
