What is Natural Gas?
Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
Much of the natural gas we find and use today began as microscopic plants and animals living in shallow marine environments millions of years ago.
Colorless and odorless in its natural state, natural gas is the cleanest burning fossil fuel. When it burns, natural gas produces mostly carbon dioxide, water vapor and small amounts of nitrogen oxides.
