Compressed natural gas (methane) is a cleaner alternative to other automobile fuels such as gasoline (petrol) and diesel. As of 2005, the countries with the largest number of natural gas vehicles were Argentina, Brazil, Pakistan, Italy, Iran, and the USA.
Natural gas is a major source of electricity generation through the use of gas turbines and steam turbines.
Natural gas is supplied to homes, where it is used for such purposes as cooking in natural gas-powered ranges and/or ovens, natural gas-heated clothes dryers, heating/cooling and central heating.
Natural gas is a major feedstock for the production of ammonia, via the Haber process, for use in fertilizer production.
Russian aircraft manufacturer Tupolev is currently running a development program to produce LNG- and hydrogen-powered aircraft.
Natural gas is also used in the manufacture of fabrics, glass, steel, plastics, paint, and other products.
The major difficulty in the use of natural gas is transportation and storage because of its low density. Natural gas pipelines are economical, but are impractical across oceans.
