Propane vs. Natural Gas: What’s the Difference?

What is Propane?

Propane is a liquid petroleum gas, often referred to as LPG and is a produced one of two ways – as a by-product of natural gas, or through the accumulation of agricultural waste. The latter method creates what is called renewable propane making it a clean and more environmentally friendly fuel option.

What is Natural Gas?

Natural gas is a fossil fuel that forms underground and contains mostly methane and also butane, propane, and carbon dioxide. Before natural gas can be used in homes, it must go through a process of removing many of the ingredients found in it. After that, it can be run through pipes to reach commercial and residential spaces.

Initially natural gas appears to be a cheaper option than propane. However, if you have to put in a gas line to reach your home, that can be an expensive up-front cost. Also, natural gas burns nearly twice as fast as propane, meaning you’ll be spending more money on fuel to stay warm or to keep your appliances running.

The two fuels are measured in different units – propane in gallons and natural gas in cubic feet. Prices for both fuels tend to fluctuate yearly, making it a little more difficult to compare the overall cost.


Because propane is longer lasting, it is a more energy efficient fuel than natural gas. If you live in a colder climate, this is an important factor to consider, as you’ll likely be using more fuel in the winter to stay warm. Propane also produces clean emissions which means it meets the standards put forth by the EPA for burned fuels. In this area, propane is the clear winner.


When it comes to our homes and family, safety is a top priority, so choosing a fuel option that is less likely to cause an issue is key. While both are highly flammable, propane has a flammability range of 2%-10% compared to 10%-15% in natural gas. Also, a natural gas leak in pipes is often difficult to detect and costly to repair. Overall propane is a safer choice and is endorsed by the National Fire Protection Agency.
