Natural gas, made up of methane and other gases, is extensively treated before use. It powers vehicles, appliances, and industries, including food processing and waste treatment.
Natural gas, also known simply as gas, is a fossil fuel made up of several gases, the most important of which is methane. A very similar gas known as biogas is produced from swamps, sewage sludge and cow manure. The gas we know as an energy source has undergone a number of processes by the time it reaches us. Before natural gas is usable as a fuel, it must be treated extensively to remove all secondary components, such as propane and sulfur. The uses of natural gas are many and varied. Consumers, industries and commerce can all benefit from its use.
Transportation: Natural gas is used in transportation to power everything from cars and trucks to heavy-duty vehicles. “Clean Air” natural gas buses are popular in Canada and some European countries, and more vehicles now run on dual fuel, allowing owners to switch from petrol to natural gas depending on needs and circumstances. The Russian company Tupolev is working on designing an aircraft capable of flying on a combination of natural gas and hydrogen.
Residential Uses: Many appliances run on natural gas, including ovens, barbecues, fireplace logs, pool and spa heaters, and fire pits. Uses of natural gas in the home also include residential heating, with 51 percent of American homes choosing gas as their primary heat source. Natural gas air conditioning isn’t as popular as the electric alternative, but it does exist.
Industry and Manufacturing: The industrial sector uses natural gas for manufacturing and energy. Natural gas is used in the production of antifreeze and plastics. Food processing industries basically use only natural gas to fuel their plants, but waste treatment and oil refining are also large consumers of natural gas. Because many gases can be extracted as a byproduct of natural gas, the uses of natural gas go beyond what the gas itself can provide.
