Advantages: 
1. Natural gas is a clean-burning, efficient source of energy with lower greenhouse gas emissions than other fossil fuels.2. Natural gas pipelines are safer than transporting hazardous liquids such as crude oil in large tankers.3. Natural gas can be transported over long distances at high volumes without losing much pressure or changing its composition.4. Natural gas is widely available and relatively inexpensive compared to other sources of energy.Disadvantages:
1. Natural gas pipelines require more infrastructure to construct, operate, and maintain than other forms of energy transmission.2. Natural gas pipelines leak occasionally, which poses an environmental risk.3. Natural gas prices can fluctuate significantly due to market conditions.4. Natural gas is not always readily accessible in remote areas due to limited infrastructure.
