Understanding Natural Gas Consumption: How Many Therms Does the Average Home Use?

Natural gas is a widely used energy source for heating, cooking, and powering various household appliances. As an informed homeowner, it is important to have a solid understanding of natural gas consumption in order to effectively manage energy usage and make informed decisions regarding energy efficiency. In this article, we will delve into the topic of natural gas consumption and explore how many therms the average home uses, highlight the factors that influence consumption, and provide expert insight on how to optimize energy use.

What is a therm?

Before diving into the average natural gas consumption of a typical home, it is important to understand the concept of a “therm. A therm is a unit of energy measurement used for natural gas consumption. It is equal to 100,000 British thermal units (BTUs). This unit allows for standardized measurement and comparison of natural gas consumption across households and regions.

Understanding average residential natural gas consumption

Residential natural gas consumption can vary based on several factors, including geographic location, seasonal variations, and home size. While averages provide a general idea, it’s important to remember that individual usage can vary from these numbers. Let’s explore this topic further:

Seasonal differences

Typically, homes tend to use less thermal energy in the summer months compared to the winter months. This is primarily because natural gas use for heating decreases during the warmer seasons. For example, in California, residents use an average of 40 therms per month in the winter, but only about 16 therms per month in the summer.

Geographic variations

Natural gas consumption can vary significantly by location. In Georgia, the average annual natural gas consumption per household is approximately 717 therms. It’s worth noting that regional climate patterns play a significant role in determining natural gas consumption. Areas with colder climates generally have higher natural gas consumption due to increased heating needs.

Impact of home size

The size of your home also affects the amount of natural gas you use. Larger homes typically require more energy to heat and maintain comfortable temperatures, resulting in higher thermal usage. Conversely, smaller homes tend to use less natural gas due to reduced heating needs.

Heating a major contributor

Heating accounts for a significant portion of residential natural gas consumption. As a result, the colder the climate, the more natural gas is typically used for heating. It’s important to consider this factor when estimating your household’s natural gas consumption.

Limitations of averages

While averages can provide a general benchmark, it’s important to recognize that they may not accurately represent every household’s natural gas usage. Individual circumstances and preferences can cause significant variation. Some households may not use natural gas at all, relying on alternative energy sources for their heating and cooking needs.

Factors that affect natural gas consumption

Several factors affect the amount of natural gas used in a home. While average natural gas usage can vary depending on a variety of circumstances, the following factors play a significant role:

Climate and weather

The climate and weather patterns in a particular region have a significant impact on natural gas consumption. Homes in colder climates tend to use more natural gas for space heating during the winter months, while homes in milder climates may have lower heating needs.

Home size and insulation

The size of a home and the quality of its insulation affect natural gas consumption. Larger homes generally require more energy to heat and maintain comfortable indoor temperatures. Similarly, poor insulation can result in heat loss, leading to increased gas consumption to compensate for the energy loss.

Energy efficiency

The energy efficiency of appliances, including furnaces, water heaters, and stoves, plays a critical role in natural gas consumption. Older, less efficient appliances tend to use more gas than newer, more energy-efficient models. Upgrading to energy-efficient appliances can significantly reduce natural gas consumption.

Occupancy and lifestyle

The number of people in a home and their lifestyle choices affect natural gas consumption. More people in a household typically result in higher consumption due to increased heating and hot water needs. In addition, activities such as extended showers, frequent laundry loads, and extensive cooking can contribute to higher energy consumption.

Average natural gas consumption for a home

While it is difficult to determine an exact average natural gas consumption for all homes, several studies and industry data provide valuable insights. On average, a residential home in the United States uses approximately 50 to 100 therms of natural gas per month. However, it is important to note that this number can vary significantly based on the factors mentioned above.

Tips for optimizing natural gas use

To optimize natural gas usage and promote energy efficiency in your home, consider implementing these expert tips:

Upgrade to energy-efficient appliances

Invest in energy-efficient furnaces, water heaters, and appliances. Look for ENERGY STAR®-certified products that meet or exceed industry standards for energy efficiency. These appliances can significantly reduce your natural gas consumption while providing the same level of performance.

Improve home insulation

Make sure your home is properly insulated to minimize heat loss. Insulate walls, attics, and basements, and seal any gaps or cracks that could allow drafts. Adequate insulation helps maintain indoor temperatures and reduces the need for excessive gas consumption.

Program your thermostat

Use a programmable thermostat to efficiently regulate indoor temperatures. Set lower temperatures when the home is unoccupied or during sleeping hours, and raise them when needed. This practice can result in significant energy savings over time.

Practice energy-conscious habits

Practice energy-conscious habits to reduce natural gas consumption. Take shorter showers, wash laundry in cold water when possible, and avoid leaving doors or windows open while the heat is on. These small adjustments can add up to significant energy savings.

Schedule regular maintenance

Schedule annual maintenance for your heating system to ensure optimal performance. Regular inspections and tune-ups can identify and correct any problems that could lead to excessive gas consumption.

Calculate natural gas consumption: estimating your therms Uuage

If you’re considering switching to natural gas or already have it installed in your home, understanding how much natural gas you use is valuable information. Natural gas consumption is typically measured in therms or BTUs (British Thermal Units). One therm is equal to 100,000 BTUs. For natural gas appliances, one therm represents the energy required to heat one gallon of water by 100 degrees Fahrenheit.

To calculate your natural gas consumption, you’ll need to know the BTU rating of your appliances and how often you use them. Most appliances provide this information in their owner’s manuals or on energy labels. Once you have this information, you can use the following formula to calculate your natural gas consumption:

BTUs per hour x hours per month / 100,000 = Btu of natural gas used per month.

For example, let’s consider a natural gas water heater with a BTU rating of 40,000 BTUs per hour. If you use it for two hours a day, your monthly gas consumption would be 1,920 therms ((40,000 x 2 x 30) / 100,000). To determine your annual natural gas consumption, multiply your monthly usage by 12. In this example, it would be 23,040 therms of natural gas used in a year ((40,000 x 2 x 30 x 12) / 100,000).

It’s important to note that actual usage may vary depending on appliance efficiency, climate conditions, and personal habits. However, these calculations should provide you with a reasonable estimate of your natural gas consumption.

By monitoring your natural gas usage, you can make informed decisions about energy efficiency and potentially identify areas where you can reduce consumption. By upgrading to more efficient appliances, improving insulation, and adopting energy-conscious habits, you can reduce your natural gas consumption and contribute to a greener and more sustainable future.

Bottom line

Understanding residential natural gas consumption is essential for homeowners looking to optimize energy use and promote sustainability. While average natural gas consumption varies based on factors such as climate, home size, and occupant behavior, it typically ranges from 50 to 100 therms per month. By implementing energy-efficient practices, upgrading appliances, improving insulation, and adopting energy-conscious habits, homeowners can reduce natural gas consumption and contribute to a more sustainable future while enjoying the comfort and convenience of natural gas-powered amenities.

Medium (3-bedroom house / 2-3 people) Gas: 12,000 kWh Elec: 2,900 kWh
High (5-bedroom house / 4-5 people) Gas: 17,000 kWh Elec: 4,300 kWh


How many cubic feet of natural gas does a home use?

196 cubic feet

On a daily basis, the average U.S. home uses 196 cubic feet of natural gas. Natural gas comprises almost one-fourth of all primary energy used in the U.S. and is directly linked to jobs and economic health. The natural gas industry supports the employment of nearly 3 million Americans in all 50 states.

How many therms of gas per month is normal?

The U.S. Department of Energy estimates that the “average” household uses a little less than 1/2 a therm per day just for the water heater, but the actual amount of therms used per month can vary widely. Donna Ohl, Grady Volunteer Coordinator, posted 15 years ago that she used 120 therms in the last 30 days (about 4 therms per day), while Anthony Matonak, one person, used 5 therms in the last month. Rick Blaine, one person, used 43 MCF last year (about half for cooking and hot water and half for heating). CJT, in their town (CT, USA), pays $24 per month for weekly garbage and recycling pickup. Gary Heston, two people, in a 2400 square foot house, used 1,011 KWH of electricity, $23.04 for sewer, $29.00 for garbage pickup, and 155 therms of natural gas for one month. Nate Nagel, two people, in a house of 2400 square feet, used 90 therms of natural gas for a month. Finally, Daestrom, in upstate NY, used 5.2 therms of natural gas for a month. So the amount of therms used per month can range from as low as 5 therms to as high as 155 therms, depending on the size of the house, climate, insulation, and other factors.

Is natural gas cheaper than electricity?

Whether natural gas is cheaper than electricity depends on several factors, including region, energy use, and the efficiency of the appliances used. In some regions, natural gas is cheaper than electricity, while in others, electricity may be more affordable.

In general, natural gas tends to be less expensive than electricity for heating and cooking. This is because natural gas is a highly efficient fuel source, meaning it can produce more heat per unit of energy than electricity. In addition, natural gas prices have historically been more stable than electricity prices.

However, for some uses, such as lighting, refrigeration and air conditioning, electricity can be more cost-effective, especially with the increasing availability of renewable energy sources such as wind and solar power.

Ultimately, the cost of energy depends on many factors, including local supply and demand dynamics, the regulatory environment, and the specific energy needs of each household or business. It is always a good idea to compare energy prices and options to determine the most cost-effective option for your specific situation.

As illustrated, even when a range of electric prices are considered, natural gas prices are consistently two to three times lower than electric prices. In fact, when all charges are considered, for a $0.06 per kilowatt hour (kWh) electricity rate to be competitive, natural gas would have to cost $1.77 per therm.
