Experts, like the U.S. Department of Energy, say standby generators are best for whole-home backup. Portable generators are better for short-term power or outdoor use.

Which is right for you?

Pick a generator that fits your needs and budget. Portable diesel generators cost about $3,000 to $15,000. Standby generators cost more because they last longer and give more power. Generac, Cummins, and Caterpillar are top brands. Generac has cheaper models that last 20-30 years. Cummins makes quiet generators with smart features. Kohler has strong models for big homes.

Use portable generators for short blackouts, camping, or building sites. Standby generators are best for whole-home backup and emergencies. Pick portable if you want to save money and need flexibility. Pick standby if you want automatic power and more dependability.

Tip: Always check your local rules and talk to an expert before you put in a generator.

Diesel vs. other fuel types

Diesel vs. gasoline

Diesel and gasoline are different for home backup. Diesel fuel has more energy, so it lasts longer. You use less diesel to run your generator. Diesel also stays good in storage for a long time. Gasoline goes bad faster than diesel. Diesel can last up to 18 months without help. If you add stabilizers, diesel lasts up to 36 months. Gasoline only lasts 6 months without help. With stabilizers, gasoline lasts up to 15 months.

Diesel’s long shelf life helps you in emergencies. Gasoline breaks down fast, so you need to replace it often. Diesel keeps working well, so it is a smart choice. The U.S. Department of Energy says diesel is reliable for backup power.

• Diesel fuel gives more energy than gasoline.

• Diesel lasts longer in storage, so you worry less.

Diesel vs. propane/natural gas

Propane and natural gas burn cleaner than diesel. Propane makes less pollution, so it is better for the environment. Natural gas is the cleanest, but you need a pipeline. Diesel generators make more pollution, so you must follow rules. Some diesel engines use Diesel Exhaust Fluid to lower pollution.

Propane is easy to store and burns clean, but it has less energy. Natural gas does not need a tank, but you need a pipeline. Think about these things when you pick a fuel type.

Home use considerations

You want fuel that is easy to get and store. Diesel is easy to find and refill. Propane is clean and stores well, but you need a tank. Natural gas works best if you have a pipeline close by. Here is a quick comparison:

A portable diesel generator gives you strong power and easy refueling. You need to think about pollution, fuel storage, and local supply before you choose.
