Portable generators are extremely helpful gadgets that allow you to power electrical devices nearly anywhere, whether in the backyard or in the middle of nowhere. Many campers utilize the finest portable generators to bring a few home comforts with them into the great outdoors – image sitting with your buddies and watching a movie beneath the stars at a forest campground. Concurrently, contractors and builders use them to power tools on building sites that have not yet been connected to mains electricity.

Whatever you intend to use them for, if you’re seeking to buy a portable generator, you’ll be faced with a decision: gas or dual-powered generator? Let’s go over the advantages and disadvantages of each fuel type.

Is A Dual Fuel Generator Worth It?

A dual fuel generator provides the assurance that you will have electricity no matter what happens outside. Natural calamities such as hurricanes and earthquakes can cause gasoline supplies to be disrupted. If you rely on that one form of fuel, you may be limited to what you have at home.

Dual Fuel Vs Gas Generator

Dual fuel and gas generators work in similar ways, but they differ in the kind and amount of fuels that may be used. Natural gas, gasoline, liquid propane gas, diesel, or solar energy can all be used in these systems. A dual power generator may switch between two fuel kinds automatically to extend its runtime, whereas gas generators can only utilize one fuel type. The switchover occurs based on fuel availability and the most efficient fuel source at the moment.

What is a Dual Fuel Generator?

A dual fuel generator, as the name implies, employs two distinct types of fuel, often gasoline and propane, to increase runtime. The switching between the two fuel types is generally automated, based on fuel supply and the fuel judged most efficient at the moment. This is seen as a significant benefit not only for homes but also for persons who are always on the go, such as campers or mobile food trucks.

A dual fuel generator is also the greatest option for folks who live in distant places and contractors who operate on remote project sites. A dual fuel generator also allows you to choose the most appropriate fuel for your conditions, allowing you to tailor a performance to your demands. For example, if you relocate to an area where gasoline is unavailable, you may operate your generator on propane until you can refuel. You may also operate the generator on propane while traveling and bring gasoline with you in case you run out of fuel in the middle of nowhere.

The efficiency of gas generators is lower. While natural gas is often less costly, it does not transport as much energy. Although diesel is commonly accessible, weather events may cause delays in delivery. Long-term operation necessitates on-site storage.

Gas Generator

What is Gas Generator?

A gas generator is a type of generator that uses natural gas instead of traditional fuels like gasoline, diesel, or propane. Natural gas is easily available even in the lack of power, and in recent years, these generators have accounted for the lion’s share of the market. These generators are a wonderful alternative to the diesel or dual fuel generators mentioned above, and they produce adequate power when needed. They can handle everything from keeping factories operating to keeping different critical equipment in your house turned on.

Natural gas generators are simpler to operate, less expensive, and better for the environment than ones that use fossil fuels. However, because natural gas is less versatile than other fuel sources, these generators may not be suitable for all applications.

What is Gas Generator

Where Natural Gas Generators are used

Gas generators may be utilized in a variety of situations and are widely accessible across the world. Large institutions that require a constant source of electricity, such as hospitals and nursing homes, typically employ natural gas generators rather than ones fueled by gasoline or diesel. For example, gasoline has a limited shelf life and may be unavailable when you need it the most.

Diesel generators, on the other hand, are a major source of air pollution, and propane tanks might become limited during natural disasters. This makes natural gas the most practical alternative, and it is for this reason that most homeowners choose these generators since they do not have to deal with the hassle of replenishing fresh fuel on a regular basis.


Natural gas generators are commonly employed by electric utilities to satisfy general electric load needs since natural gas is easily available. As such, they are an ideal replacement in areas lacking a centralized power plant.

Industrial applications

Various companies, manufacturing plants, and commercial establishments cannot overestimate the benefits of natural gas generators since they provide up to 90% energy efficiency. These generators are well-known for not only supplying power for electrical loads but also heat energy for the facility’s thermal requirements.


Because the fuel source is never in short supply, natural gas generators are a solid and trustworthy alternative for both household and industrial use. Supply pipes are widely accessible in residential areas and are not susceptible to abrupt price increases, so you won’t run out of gasoline.


Natural gas generators do not need to be replenished because the gas is delivered automatically by the utility when needed. Unlike other fuels, such as gasoline, which simply deteriorates with time, keeping significant volumes can be costly.


Natural gas generators are often less costly and provide good household emergency power options. The fuel source is likewise less expensive, but establishing running gas lines incurs more expenditures upfront.

Environmental footprint

When it comes to greenhouse gas emissions, a natural gas generator has a relatively small ecological impact. This is the polar opposite of the dual fuel generator or diesel-powered generators mentioned above. Natural gas generators also reduce soil contamination since they lack an unground fuel storage tank. So, if you care about the environment, don’t be frightened to test a natural gas unit.

Gas Vs Dual Fuel Range

Gas ranges use gas to heat the cooktop and oven. Dual fuel ranges use electricity to heat the oven and gas to heat the cooktop. The benefit of dual fuel ranges is that they use precise temperature control of electricity to heat the oven rather than the temperature variations that are common with gas ovens.

Noise Level Difference Between Dual Fuel And Gas Generator

Dual fuel generators function quietly in propane mode if noise levels are an issue. If you run out of propane and have to convert it to gasoline, the generator will be substantially noisier. If you need a generator that runs quietly, an inverter generator may be a better option.

When heard from 23 feet away, gas generators have a noise level of 70dB to 100dB. Remember that 100dB is eight times louder than 70dB, thus there is a significant difference.

Are Propane Generators Better Than Gas?

Propane generators are inefficient, generating fewer BTUs per gallon of fuel than gas generators. However, because propane burns cleaner than gasoline, it is beneficial for the environment as well as your generator.

Dual Fuel VS Gas Generators – FAQs

What lasts longer gas or propane generator?
In the same amount of time, you’ll use more than twice as much natural gas as propane. That is not to suggest that propane is less expensive than natural gas. It is more expensive. However, if you are concerned about running out of fuel, propane is a better option because it will last longer.
Is a dual fuel generator quieter on propane?
It also burns cleanly, at least as compared to gasoline. Furthermore, propane generators are often considerably quieter than gas generators, which create a lot of noise. Propane is useful for an emergency preparation pack since it can still be obtained even if there is a significant power outage.
How much propane does a dual fuel generator use?
Because generators use two to three pounds of propane per hour on average, a generator with 20 pounds of propane may run for around five hours.


To Sum Up

Both dual fuel and gas generators have advantages and cons, and your choice will be influenced by your specific scenario and power requirements. A dual fuel generator is not just economical; it also allows you to increase runtime by switching fuel types. A natural gas generator, on the other hand, is one of the most affordable and widely available alternative energy sources, yet it is still incredibly efficient.
