Propane and electricity are two energy sources that power many homes. They are measured in different units: propane in gallons, pounds, and cubic feet, and electricity in kilowatts. Propane is a primary energy source, whereas electricity is secondary. This means that propane can be used directly, while electricity must be generated from another energy source, such as natural gas or petroleum. The cost of propane and electricity varies by region, but generally, propane has been considered a better value and more cost-effective option. However, the cost of propane has been rising, making electricity a more affordable option in some cases.

Propane is a primary energy source, electricity is secondary
Propane is a primary energy source, whereas electricity is a secondary energy source. This means that propane can be used as is, while electricity needs to be created by another energy source. This distinction has implications for the cleanliness, efficiency, and cost of the two energy sources.
Propane is an energy-rich gas with the chemical formula C3H8. It is composed of three carbon atoms and eight hydrogen atoms. Propane is a by-product of natural gas processing and petroleum refining and is often a constituent of liquefied petroleum gas (LPG). It is a popular choice for barbecues, portable stoves, and heating due to its low boiling point, which allows it to vaporize inside pressurized liquid containers. Propane is also used for grain drying, powering farm equipment, and as a transportation fuel. As of 2014, 6.2 million American households used propane as their primary heating fuel.
As a primary energy source, propane has certain advantages over electricity. Propane can be stored safely in tanks and is not subject to power outages. It is also recognized as a ""green"" energy source, helping to reduce emissions and protect the environment. Propane is non-toxic, produces minimal emissions, and is not harmful to soil or water. Additionally, propane has a built-in safety property: it will not ignite when combined with air unless the source of ignition reaches 940°F.
On the other hand, electricity is a secondary energy source because it is produced by converting primary energy sources such as coal, natural gas, nuclear energy, solar energy, and wind energy into electrical power. It is an energy carrier, which means it can be converted into other forms of energy such as mechanical energy or heat. While electricity has zero emissions, the primary energy sources used to generate it may be less environmentally friendly. According to the U.S. National Library of Medicine, about 62.7% of electricity generated comes from fossil fuels, with 30.1% attributed to coal.
In terms of cost, propane is generally more cost-effective than electricity, especially with higher-voltage appliances. Propane heaters, for example, can save homeowners nearly $2,000 over the average lifespan compared to electric heaters. Propane clothes dryers can also complete drying tasks in approximately three-quarters of the time it takes an electric dryer. However, it is important to note that the cost of propane can vary significantly from state to state, and the availability of propane or electricity in a particular region may influence the decision to choose one over the other.

Propane is non-toxic, produces minimal emissions and is safe
Propane is a non-toxic, non-poisonous fuel that is generally considered safe and produces minimal emissions. It is a primary energy source, unlike electricity, which is secondary, and can be used 'as is'. This means that electricity always requires a primary energy source to be created, which affects its cleanliness and efficiency. According to the U.S. National Library of Medicine, 62.7% of electricity generated comes from fossil fuels, with 30.1% coming from coal. Propane, on the other hand, has a lower carbon content than conventional gasoline and diesel fuel, and renewable propane can have a carbon intensity four times lower than conventional propane.
Propane burns cleaner than other fuels and produces environmentally friendly emissions. It will not create an environmental hazard if spilled, so homeowners can install propane tanks above or below ground without worrying about contamination. Propane use reduces greenhouse gas emissions by nearly 13% and offers life cycle benefits over conventional fuels when used as a vehicle fuel.
While propane tanks can explode under extreme conditions, they are generally very safe. Modern tanks have safety features and are designed to withstand high-powered rifle shots and fires. If a tank is exposed to extreme heat, it will pop a relief valve and vent the propane vertically, preventing an explosion.
However, propane does require more maintenance than electricity. Homeowners must monitor their propane supply and reorder when it runs out. In contrast, electric homes only require occasional check-ups to ensure wiring, circuit breakers, outlets, and plugs are in working order.

Propane is more cost-effective for high-voltage appliances
Propane is a primary energy source, whereas electricity is a secondary energy source. This means that propane can be used directly, while electricity must be generated from another energy source, such as natural gas or petroleum. This difference can affect the cost, efficiency, and cleanliness of the two energy sources.
Propane has long been recognized as a "green" energy source. It produces very low levels of emissions and is approved as an alternative fuel in the Clean Air Act of 1990 and the National Energy Policy Act of 1992. Propane is also non-toxic, non-poisonous, and safe, as it will not ignite unless the source of ignition reaches 940°F. Additionally, propane can be stored safely in a tank and is not subject to power outages, making it a more dependable energy source than electricity.
When comparing the costs of propane and electricity, it is important to consider the price per unit. If the cost of propane is less than the cost of electricity per kilowatt-hour multiplied by 27, then propane is the more economical option. Propane has been considered more cost-effective, especially for high-voltage appliances, as the cost gap between the two energy sources grows with higher voltage. For example, propane water heaters are about 42% cheaper than electric water heaters, saving homeowners over $2,000 over their lifespan. Propane clothes dryers can also complete drying tasks faster than electric dryers and save up to 65% in costs.
However, it is worth noting that the cost of propane has risen dramatically, and in some regions, electricity may be the more economical option. Additionally, electric homes require less maintenance than propane, as propane requires regular reordering of the fuel supply. Furthermore, some states offer rebates for homes that switch from oil to electric heating, which can offset the cost differences and result in long-term savings.
