What Do Backup Generators Run On?

what do backup generators run on

If you are considering buying a backup generator for your home, you may be wondering what kinds of fuels it will run on. These fuels include propane (LP), natural gas, and diesel. Which one you choose will depend on the amount of energy you need and where you live.

Natural gas

If you’re considering investing in a generator for your home, you may want to consider the benefits of natural gas. These backup generators cost less to operate than gasoline, propane or diesel generators, so they can save you money.

In addition to its lower costs, natural gas also produces less environmental emissions than gasoline. It is cleaner burning and burns more efficiently.

Because it can be stored, natural gas generators are easier to transport than gasoline or propane generators. This makes them a good option for people living in areas with limited access to fuel.

Natural gas is a reliable backup power source during an emergency. When the main electrical system is out of commission, the backup generator automatically switches on. Then, it monitors the power and keeps the lights on.

The benefits of using a natural gas generator include reduced maintenance and installation costs. It can help you stay safe from dangerous levels of carbon monoxide. You can install a natural gas detector in your house to prevent the buildup of dangerous levels of CO2.

Natural gas prices are down, which means you can save even more money by purchasing a generator that runs on this fuel. Prices are at their peak in 2008, but they have dropped by 50% since then.

Liquid propane (LP)

Liquid propane (LP) is what backup generators run on. This fuel is generally more affordable and offers less noise than natural gas. It is also a clean burning fuel that can last longer.

Propane is a common fuel for homes. It is cheaper than diesel or gasoline and is considered a clean, safe fuel. It is stored in underground tanks.

Liquid propane portable generators are popular for home backups during power outages. These devices allow consumers to control the level of fuel in their tank. It has a relatively long shelf life, and can be refilled by a fuel service provider.

In colder climates, propane is a better choice for emergency power. It can run for a longer time than natural gas. The disadvantage of using LP is that it produces less power per gallon. This can be a concern if you need to run a larger appliance.

The cost of LP can vary with the season. It’s also important to make sure you have enough fuel in your tank before a storm hits. It’s best to purchase a fuel storage container.

During a major remodeling project or construction, it’s important to have a backup generator that’s essential. Choosing the correct model for your home is critical.

When looking for a portable generator, liquid propane is the most environmentally friendly option. It is a byproduct of petroleum refining, and is therefore a cleaner and greener choice than most other fuels.


Diesel is one of the primary fuels for backup generators. It has several advantages over other fuels. It is easier to start, offers a reliable power source, and has lower maintenance costs. However, it is important to know the facts about this fuel.

The viscosity of diesel fuel is a factor to consider. When it is very cold, the fuel can change from a thick liquid to a gel-like substance. This can cause hard starts and poor performance. In addition, it can also clog your fuel filter.

Another disadvantage of using diesel is its high emissions. It emits nitrous oxides, sulfur dioxide, and particulate matter. These can exacerbate respiratory illnesses.

Luckily, there are ways to avoid this issue. For instance, blending diesels is a simple solution. By using a combination of #1 and #2 fuels, the amount of diesel can be reduced without compromising the power output.

Other alternatives to diesel include biodiesel and straight vegetable oil. These types of fuel can be used with standard fuel injectors. Those who choose to use these types of fuel can expect a longer life cycle and greater flexibility.

Although there are many benefits to using a diesel generator, there are still some drawbacks. Some of these are the noise levels and the cost.
