Types of Backup Generators

backup generator types

There are several different types of backup generators. These include diesel fuel, natural gas, and hybrid types. Each one provides a different level of protection. These can be used during a natural disaster or during a power outage. The best choice depends on your personal needs, as well as your budget and location.

Diesel fuel

The use of diesel fuel in backup power systems is common, but it is not the only option for backup generators. There are several other fuel sources that engineers can choose from, such as natural gas or LP fuel. Some engineers may also opt for a dual fuel system, combining natural gas and diesel. Before making your final decision, be sure to explore the pros and cons of each fuel source. Also, be sure to contact your local AHJ to learn more about policies regarding fuel use.

Proper storage and monitoring of diesel fuel is vital to the longevity of this type of backup generator. Without routine maintenance, fuel could become contaminated and lead to damage to the generator.


Propane and natural gas are two fuel sources that are often used in backup generators. These fuel sources are both clean and environmentally friendly, and have certain advantages. For one, propane has no expiration date, and it is easily available at gas stations. It is also easy to store. Additionally, it offers a high power output, and is a great value.

Propane generators are also known for their reliability. The only drawback is that they are slightly less powerful than gasoline generators. They are also slightly quieter.

Natural gas

Natural gas is a great choice for backup generators. This fuel source has several advantages over other fuels, including the fact that it’s cheaper to purchase, easier to maintain, and safer for the environment. Not only that, but the use of natural gas in backup generators also lowers operating costs.

Natural gas generators can be connected to your gas lines, which means you won’t have to worry about storing and transporting fuel. They’re also less noisy, and they’re cleaner than diesel generators. But there are a few downsides to using natural gas as a backup generator.

Natural gas is the most environmentally friendly alternative to diesel and gasoline generators. It also produces the lowest carbon footprint, making it a great choice for environmentally conscious consumers. Natural gas generators are 30% cleaner than the closest comparable home generator, making them an ideal choice for those seeking peace of mind and environmental responsibility. Whether you’re looking for a home backup generator for sale for your family or for yourself, natural gas is a solid choice. For residents of Florida, a home backup generator is particularly important, as hurricanes can knock out power lines and damage local infrastructure.


Hybrid backup generators offer a number of benefits. For one, they reduce fuel costs. Additionally, their reduced demand on the main unit reduces wear and tear on it. This means that it will last longer than a generator that is used as a sole backup source. A few factors may determine whether or not a hybrid backup generator will be a good option for your home or business.

Another advantage is that hybrid generators are incredibly quiet. This makes them a great choice for work sites with strict noise regulations. They also require less fuel than diesel generators do, which means significant fuel cost savings.


If your power goes out for any reason, there are many options for gasoline backup generators. Gasoline fuel generators are a great option because they are affordable and readily available. Additionally, gas does not go bad like diesel or other petroleum products, which makes them an environmentally friendly choice. However, gasoline is more expensive than diesel, and if you don’t store it properly, you might have to deal with hazardous fumes.

The downside to gasoline is that it may be difficult to obtain in a disaster situation. Gasoline stores may be closed or depleted, or there may not be any gasoline at all. Also, gasoline tends to stale and can gum up the carburetor. If you don’t store it properly, it will cause the generator to become inoperable. Fortunately, there are tri-fuel generators that run on common vapor fuels and can use gasoline as needed. Natural gas and liquid propane are readily available and don’t pose the same problems as gasoline.
