A: Natural gas (largely methane) burns more cleanly than the other fossil fuels (45% less carbon dioxide emitted than coal and 30% less than oil)
It is easily transported via pipelines and fairly easily using tankers (land and sea)
It can be piped into homes to provide heating and cooking and to run a variety of appliances.
Where homes are not piped, it can be supplied in small tanks.
It can be used as a fuel for vehicles (cars, trucks and jet engines) where it is cleaner than gasoline or diesel.
It is used to produce ammonia for fertilizers, and hydrogen, as well as in the production of some plastics and paints.
It's relatively abundant, clean burning and seems easy to distribute.
It's also lighter than air, so if there is a leak it will tend to dissipate, unlike propane, which is heavier than air and pools into explosive pockets.
It can be used for heating, cooking, hot water, clothes dryer, backup generator power, and so forth.
Some places will supply it to your house by way of underground pipes.
Natural gas is more economical than electricity,
it is faster when used in cooking and water heating and most gas appliances are cheaper than electrical ones.
Gas appliances also do not create unhealthy electrical fields in your house.
