What You'll Learn
Natural gas is the most common heating fuel
The majority of homes in the West and Midwest use natural gas for heating. In New York State, three out of five homes use natural gas, and it is the heating fuel of choice for 49% of all buildings in the United States. Across the country, around 50% of homes use natural gas for heating. This is a much higher proportion than the 5.7 million households that use heating oil, which is mostly used in the Northeast.
Natural gas is a proven, reliable fuel source that has been used for many years. It is a mixture of hydrocarbons, predominantly methane (CH4). It is formed over millions of years by the action of heat and pressure on organic materials, such as algae and plants. It is also created by methanogenic organisms, which produce methane from carbon dioxide.
Natural gas is a popular choice for heating because of its affordability and efficiency. It is piped directly into homes, so there is no need for unsightly gas tanks, and it is more efficient than other fossil fuels. New high-efficiency natural gas furnaces can operate at 98% efficiency, helping to reduce costs and environmental impact.
However, natural gas is not the only option for heating homes. Geothermal heat pumps are becoming an increasingly popular alternative, offering higher efficiency and lower costs over the lifetime of the system.

Fossil fuel heating costs are rising
The rising costs of fossil fuel heating are driven by the global energy crisis and the fastest-growing inflation in 40 years. The surge in demand for fossil fuels, such as the U.S.'s high production and export of liquified natural gas, also contributes to the rise in prices.
The impact of these rising costs is significant, with many Americans already struggling to afford their energy bills. Low-income households are particularly vulnerable, and the concern is that higher heating costs will further stretch their finances.
To address this issue, there have been calls for investing in renewable energy sources. However, utility companies find it challenging to transition their energy sources in the short term. Additionally, there is misinformation spread by fossil fuel interests, blaming clean energy policies for the price hikes.
Homeowners can consider switching to electric heat pumps, which are generally more efficient and cost-effective than traditional fossil fuel-based heating systems. However, the upfront costs of installing electric heat pumps can be high, and some homes may not have the land required for the underground trench needed by geothermal heat pumps.

Heat pumps are an efficient alternative
The cost of heating a home using fossil fuels varies depending on factors such as the size of the home, the type of fossil fuel used, and the region. For example, the average American homeowner spends over $2,000 a year on all utility bills, but this can be much higher in places with long winters. Natural gas is the most common heating fuel source in the United States, with 49% of all buildings in the country using it. Other fossil fuel options include propane and oil, which can be more expensive due to the need for regular deliveries and the installation of unsightly gas tanks.
Heat pumps offer an efficient and environmentally friendly alternative to fossil fuel heating. They use electricity to transfer heat from a cool space to a warm space, making them highly effective in both heating and cooling modes. Heat pumps are particularly advantageous in moderate climates and can provide up to 400% efficiency without burning any fossil fuels. In addition, they can reduce electricity use for heating by up to 75% compared to electric resistance heating and can also improve dehumidification, resulting in reduced energy usage and increased comfort during summer months.
While heat pumps have historically struggled to perform efficiently in freezing temperatures, technological advancements have improved their cold-weather performance. For example, in Norway, 60% of households are equipped with heat pumps, and they do not need to rely on backup fossil fuels. It is important to consult with an installer familiar with heat pumps to ensure the system is suitable for the local climate.
The upfront cost of installing a heat pump can be high, typically ranging from USD 3,000 to USD 6,000 for an air-to-air heat pump. However, financial incentives and subsidies are available in many countries, making heat pumps a more affordable option. Additionally, heat pumps can provide long-term savings by reducing households' exposure to fossil fuel price spikes and lowering energy costs compared to traditional heating methods.
In conclusion, heat pumps offer a highly efficient and sustainable alternative to fossil fuel heating. They can significantly reduce greenhouse gas emissions and dependence on natural gas, making them a key technology in the global transition to secure and sustainable heating. With sales of heat pumps on the rise and governments offering economic incentives, heat pumps are an increasingly attractive option for homeowners looking to reduce their environmental impact and heating costs.

Electric heat systems have higher monthly costs
The choice between electric and gas heat systems can significantly impact your energy bills. The most common electric heat systems have higher monthly operating costs compared to the most common natural gas systems. Natural gas heating costs around $540 per year, while electric heating ranges from $900 to $2,500 annually, depending on the type of system and electricity rates. The average cost of electricity in the U.S. is 16.94 cents per kilowatt-hour or kWh. For the winter of 2024-2025, the average cost of gas heat for U.S. homeowners is projected to be $602, while electric heating costs are expected to average $1,054.
However, it is important to note that the efficiency of the heating system also plays a significant role in overall heating costs. Modern high-efficiency gas furnaces can achieve an AFUE rating of up to 99%, while electric heating systems have an efficiency of 100%. Heat pumps, a type of electric heating system, can be highly efficient, especially in moderate climates, with a Coefficient of Performance (COP) of 3 or higher. They can deliver 3 units of heat for every unit of electricity consumed, resulting in lower operating costs compared to traditional electric resistance heating.
