Natural Cas Is the Purest Fossil Fuel

Natural gas burns more cleanly than petroleum and much more cleanly than coal. This purest of fossil fuels contains negligible quantities of sulfur hence, insignificant amounts of sulfur dioxide are produced. Also, because natural gas burns at lower temperatures, only small amounts of nitrogen oxides are released. Perhaps most important, however, is that generating energy from natural gas produces less carbon dioxide—about half as much as is produced from burning 

Petroleum is easily and cheaply transported because it is a liquid. 

Natural gas is stored in large spherical tanks because this shape holds the greatest volume for a given amount of containment material. 

If you use gas and it is stored outside your home in a pressurized tank, you are using propane. If there is no tank outside your home, you are using methane.
