Uses of Natural Gas


Natural gas is an important fuel and a raw material in manufacturing.



Natural Gas: A Fuel and a Raw Material



Natural gas is used in an amazing number of ways. Although it is widely seen as a cooking and heating fuel in most US households, natural gas has many other energy and raw material uses that are a surprise to most people who learn about them.

In the United States, most natural gas is burned as a fuel. In 2012 about 30% of the energy consumed across the nation was obtained from natural gas (1). It was used to generate electricity, heat buildings, fuel vehicles, heat water, bake foods, power industrial furnaces, and even run air conditioners!


22 Trillion Cubic Feet



During 2009 the United States consumed about 22.8 trillion cubic feet of natural gas. That's enough gas to fill a room with a footprint the size of Pennsylvania and about 18 feet high. Most of that gas was delivered to nearly 70 million homes and places of business through more than a million miles of natural gas pipelines (2).


Uses of Natural Gas in US Homes



Over one-half of the homes in the United States are supplied with natural gas. About 21% of the natural gas consumed in the United States during 2013 went to homes (1). This gas is delivered to homes through pipelines or in tanks as CNG (compressed natural gas). Most of the natural gas consumed in homes is used for space heating and water heating. It is also used in stoves, ovens, clothes dryers, lighting fixtures and other appliances.


Natural gas consumption by residential and commercial customers
Residential and commercial demand for natural gas is highest in the winter when people burn gas to heat their homes and businesses. Since few people cool their home or business in summer with natural gas air conditioners the summer demand is much lower. Image by U.S. Energy Information Administration.


Uses of Natural Gas in Commercial Buildings



In 2013 about 14% of the natural gas consumed in the United States went to commercial buildings. The use of natural gas in commercial buildings is similar to its use in residences. It is used mainly for space heating, water heating and sometimes for air conditioning.


Electric Power Generation



The electric power industry was the largest consumer of natural gas in the United States during 2013. About 34% of natural gas consumption was used to make electricity.

Of the three fossil fuels used for electric power generation (coal, oil, natural gas), natural gas emits the least carbon dioxide per unit of energy produced. It emits 30% less carbon dioxide than burning oil and 45% less carbon dioxide than burning coal. Burning natural gas also releases lower amounts of nitrogen oxides, sulfur dioxide, particulates and mercury when compared to coal and oil (3).

As the United States becomes more concerned about climate change, carbon dioxide emissions, and air quality, the use of natural gas for electricity generation is expected to increase.


Natural gas demand by electric power and industrial customers

Since very few homes and businesses have natural gas air conditioners the demand goes to electricity. Image by U.S. Energy Information Administration.


Industrial Uses of Natural Gas



Natural gas is used in a wide variety of manufacturing processes. About 31% of the 2013 consumption of natural gas in the United States was by industry. Natural gas is used as both a raw material and as a source of heat.

Natural gas is an ingredient used to make fertilizer, antifreeze, plastics, pharmaceuticals and fabrics. It is also used to manufacture a wide range of chemicals such as ammonia, methanol, butane, ethane, propane and acetic acid.

Many manufacturing processes require heat to melt, dry, bake or glaze a product. Natural gas is used as a heat source in making glass, steel, cement, bricks, ceramics, tile, paper, food products and many other commodities. Natural gas is also used at many industrial facilities for incineration.


Oil & Gas and Pipeline Industry Use



Companies that produce and transport natural gas are also consumers. Transporting natural gas through pipelines requires compression stations to keep the gas pressurized and flowing through the pipeline. Many of these compression stations use natural gas as a fuel. Many oil refineries use natural gas for heating and power generation.


Natural Gas as a Vehicle Fuel



Natural gas has an enormous potential for increased use as a vehicle fuel. The main barriers to this have been the short range of the vehicles, limited refueling options, and slow refueling times. However, over the past few years refueling station prices have dropped to just a few hundred dollars and these can be placed in residences where the vehicles can be refueled overnight or between trips.

Since about half of all residences in the United States are supplied with natural gas the potential to increase the number of natural gas vehicles on the road is very high. In addition, the discovery of natural gas in shale deposits around the country has increased the availability of gas and decreased the price.

Natural gas has significant advantages over gasoline and diesel fuel. Natural gas vehicles emit 60-90% less smog-producing pollutants and 30-40% less greenhouse gas emissions. It also costs less per mile to operate a natural gas vehicle compared to a gasoline or diesel vehicle (4). And, natural gas is produced locally instead of imported.

 U.S. Government Natural Gas Studies
Natural Gas Fleet Studies
The United States government has done many cooperative studies with businesses, local governments and public agencies related to the use of natural gas as a fleet vehicle fuel. The results of these studies have overwhelmingly favored natural gas. Summaries of these studies and many full reports can be downloaded from the U.S. Department of Energy website (5).

 Surprising Uses Of Natural Gas
The many uses of natural gas
Natural gas is used to manufacture a wide variety of products. The fertilizer being spread in the top left image might have been made with ammonia produced from natural gas, the plastic parts of the spreader and the operator's clothing were most likely produced with the help of natural gas as an ingredient or as a fuel in the factory. Most bricks and cement are produced using natural gas as a heat source. Many pharmaceuticals and plastic bottles are made with natural gas as an ingredient. Cereal and fruits are often baked or dried using natural gas as a heat source. Images © (clockwise) Bill Grove, John Leung, Kristine Slipson, Amanda Rohde, iStockphoto.

Natural gas price graph
Natural gas prices fluctuate over time. Wellhead prices are determined by supply, demand, and general economic conditions. Prices to consumers are determined by similar factors. Image by U.S. Energy Information Administration.


 Average Residential Natural Gas Prices
Natural gas price map
The price of natural gas is not uniform across the United States. Instead, the price is determined by supply, demand, proximity to supply, regulatory environments and the cost of natural gas that is flowing in the local distribution system. Historically, people along the east coast have paid some of the highest prices. This may change as new unconventional resources such as the Marcellus Shale are developed and as more LNG arrives from low-cost producers.
