Discover the many ways we use natural gas every day. From home heating to plastic manufacturing, see how gas powers our world.
Natural gas is everywhere. It heats your home on a cold winter night. It cooks your breakfast. It generates the electricity that powers your phone. It makes the plastic in your water bottle. It even helps grow the food you eat.
Natural gas is one of the most versatile energy sources we have. It can do almost everything. This guide explores the many ways we use natural gas every day, from the obvious to the surprising.
About half of all US homes use natural gas for heating. That is roughly 60 million homes. A gas furnace works by burning gas inside a sealed chamber. The heat warms a metal heat exchanger. A fan blows air across the exchanger and through ducts into every room.
Gas heating has several advantages. It is usually cheaper than electric heating. It heats the air faster. And it works even when the power goes out, as long as the furnace has a simple ignition system.
In cold states like Minnesota and North Dakota, some homes use 1,000 therms of gas per winter. One therm is 100,000 BTUs. That is enough energy to run a TV for 40 years straight. Natural gas keeps people warm through the coldest winters on Earth.
Gas stoves are popular for a simple reason. They give you instant heat. Turn the knob and the flame appears. Turn it off and the flame disappears. No waiting for a burner to heat up or cool down.
Professional chefs almost always choose gas. They can control the temperature precisely. A high flame sears a steak. A low flame simmers a sauce. The response is immediate. Electric burners take time to change temperature.
Gas ovens also have advantages. They heat up quickly. They create moist heat, which is good for baking bread. And they still work during a power outage, as long as you can light the burner with a match.
Natural gas is the largest source of electricity in the United States. It produces about 40 percent of the country’s power. That is more than coal, nuclear, or renewables.
Natural gas power plants work by burning gas to spin a turbine. The turbine spins a generator. The generator makes electricity. There are two main types.
Simple-cycle plants burn gas to spin one turbine. They are about 33 to 40 percent efficient. They are cheap to build and quick to start.
Combined-cycle plants burn gas to spin one turbine. Then they capture the waste heat to boil water and spin a second turbine. They reach about 60 percent efficiency. Most new gas plants are combined-cycle.
Natural gas plants have a special talent. They can start and stop quickly. A gas plant can go from zero to full power in about 10 minutes. Coal plants take hours. This makes gas plants perfect partners for renewable energy. When the wind stops blowing or clouds cover the sun, gas plants fill the gap.
Natural gas powers vehicles too. Compressed natural gas (CNG) is stored in high-pressure tanks. The gas burns in an engine just like gasoline.
Natural gas vehicles produce less pollution than gasoline or diesel vehicles. They emit less CO2, less nitrogen oxides, and almost no particulate matter. That is why many cities use natural gas buses.
Los Angeles has one of the largest natural gas bus fleets in the world. Thousands of buses run on CNG. They produce less smog than the diesel buses they replaced. Some garbage trucks, delivery vans, and even cars also run on natural gas.
Liquefied natural gas (LNG) powers heavy trucks and ships. LNG has higher energy density than CNG. It can take a truck 500 to 800 miles on a single tank. Long-haul trucking companies are starting to use LNG.
Factories use natural gas in two ways. They burn it for heat. And they use it as a raw material.
For heat. Many industrial processes need high temperatures. Glass making, steel production, and food processing all use natural gas furnaces. The gas burns cleanly, so it does not contaminate the products.
As a raw material. Natural gas is the starting point for many products. The ethane and propane in natural gas are turned into ethylene and propylene. These are the building blocks of plastic. Your water bottle, phone case, and car dashboard all started as natural gas.
Fertilizer. The Haber process uses natural gas to make ammonia. Ammonia is the key ingredient in nitrogen fertilizer. About half the world’s food production depends on fertilizer made from natural gas. Without it, we could not feed 8 billion people.
Other products. Natural gas also helps make medicine, paint, antifreeze, photo film, and synthetic fabrics. It is one of the most important raw materials in the chemical industry.
Water heating. Gas water heaters heat water faster than electric models. A family of four can shower one after another without running out of hot water.
Clothes drying. Gas dryers cost less to run than electric dryers. They also dry clothes faster because they produce hotter air.
Humidity control. Museums use natural gas equipment to control humidity. This helps preserve paintings, fabrics, and historical documents.
Ice skating rinks. Natural gas powers chillers that freeze the ice in skating rinks. The gas is more efficient than electric chillers in many cases.
Pool and spa heating. Gas heaters warm swimming pools and hot tubs quickly. They can raise a pool’s temperature by several degrees per hour.
Natural gas does so many things. It keeps your house warm. It cooks your dinner. It makes the electricity for your video games. It powers buses that take kids to school. It helps make the plastic in your toys. And it helps farmers grow food. Natural gas is like a hidden helper. You cannot see it, but it is working for you all day long.
The versatility of natural gas explains its dominant role in the energy mix. It can be used for thermal applications (heating), electrical generation, transportation fuel, and chemical feedstock. Few other energy sources can claim all four.
The choice between natural gas and electricity for home appliances involves efficiency trade-offs. A gas furnace loses some energy as waste heat up the chimney. But an electric heat pump must generate electricity at a power plant first, losing energy along the way. The overall well-to-wall efficiency is often better for gas in cold climates.
For transportation, CNG is a niche fuel. It makes sense for fleets that return to a central depot every night. Buses, garbage trucks, and delivery vans fit this pattern. But for personal cars, the limited range and refueling infrastructure make CNG less practical than gasoline or electricity.
The industrial use of natural gas as a feedstock creates a special challenge for decarbonization. Even if we replace natural gas for heating with electricity, we still need natural gas (or a substitute) to make plastic and fertilizer. Chemical companies are working on ways to make these products using hydrogen or captured CO2, but the technology is not ready yet.
Home heating. A family in Chicago uses a gas furnace to stay warm through brutal winters. Their annual gas bill might be $800. Electric heating would cost twice as much.
Gas power plant. The West County Energy Center in Florida is one of the largest gas plants in the US. It can power over 500,000 homes. It uses combined-cycle technology for high efficiency.
Natural gas buses. Los Angeles operates over 2,000 natural gas buses. They travel millions of miles each year and produce less smog than diesel.
Plastic production. The US Gulf Coast has become a hub for plastic manufacturing. Cheap natural gas from fracking has made it profitable to turn ethane into plastic pellets for export.
Common Misconceptions
*“Natural gas is only for heating.”** Natural gas does far more than heat homes. It generates electricity, powers vehicles, and serves as a raw material for thousands of products.
“Electricity is the only way to power things.” Many tasks can use either gas or electricity. The choice depends on cost, efficiency, and convenience. Gas is often cheaper for heating. Electricity is often more convenient for small appliances.
“Natural gas is not used for transportation.” It is not as common as gasoline, but millions of vehicles worldwide run on natural gas. Bus fleets, delivery trucks, and even ships use natural gas.
