why is natural gas considered as clean fuel?give two reason.

 Natural gas is called a clean fuel because:

• Natural gas burns cleaner than the other fossil fuels such as coal and oil due to the highly efficient combustion process, which produces very few by-products that are released into the atmosphere as pollutants.

• Natural gas produces 70% less carbon dioxide emissions compared to other fossil fuels.

• Due to the clean burning process, natural gas does not leave residues like soot or ash when compared to coal.

• Natural gas offers a high heating value, approximately 24,000 Btu per pound.

• Natural gas is non-toxic and is not poisonous to humans if inhaled in small volumes.
