Natural gas is a human-friendly energy source

Natural gas is a colorless, transparent gas composed mostly of methane, and is characterized by lower CO2 emission than other energy sources. It does not contain carbon monoxide (CO), sulfur or other impurities that are harmful to the human body, and generates only small amounts of air contaminants. Using natural gas allows a low-environmental-burden lifestyle without sacrificing levels of comfort.
