Natural+Gas

Natural gas is formed from organic material; the decay of animal and plant matter over millions of years. This organic material is then trapped by dirt and rock, and the heat and pressure eventually converts some of the organic matter into coal, oil, and natural gas.

Natural gas consists mainly of methane, and is odorless. Because of this, mercaptan is added to natural gas to give it an unpleasant odor.

Advantages Few emissions causing less air pollution. It can be pipelined to houses, resulting in very convenient usage. It is affordable.

Disadvantages Natural gas takes up a lot of volume in its gaseous form. This can be solved by freezing it in temperatures below -162 C, turning it into a much more space efficient liquid form. Natural gas, when leaked, is dangerous and can cause explosions.
