Here are the advantages of using CNG (Compressed Natural Gas) and LPG (Liquefied Petroleum Gas) as fuels:

Advantages of CNG:
1. Environmental Friendliness: CNG emits lower levels of CO2, CO, and particulate matter compared to conventional fuels, reducing air pollution and greenhouse gas emissions.
2. Cost-Efficiency: Generally more affordable than gasoline or diesel, offering cost savings on fuel expenses.
3. Abundant Supply: Natural gas reserves are ample, ensuring a relatively stable and consistent supply.
4. Safety Features: Being lighter than air, CNG disperses quickly if leaked, minimizing fire hazards and enhancing safety.

Advantages of LPG:
1. Clean Combustion: LPG burns more cleanly, producing fewer emissions and pollutants, contributing to improved air quality.
2. Versatility: Suitable for various applications such as heating, cooking, vehicles, and industrial purposes, providing flexibility in usage.
3. Portability and Storage: LPG can be easily transported and stored in liquid form, ensuring convenience for different applications.
4. Efficient Energy Source: LPG burns efficiently, resulting in higher thermal efficiency compared to some other conventional fuels.

Both CNG and LPG offer significant environmental benefits, cost-effectiveness, and versatility, making them increasingly popular alternatives to traditional fossil fuels across various sectors and applications.
