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, hydrogensulfide, or helium.

When you burn oil or gas, they heat the surroundings. Energy is transferred from the chemicals to the surroundings. The original source of this energy is the Sun. Plants use the Sun's energy to produce sugars and oxygen from carbon dioxide and water, during photosynthesis.
