5. Gasoline Generators
Gasoline is a great option for powering portable generators, appliances, and tools that don’t require a ton of power output. The only caveat with gasoline generators is that you’ll need to frequently replenish your supply with fresh gasoline—as the shelf life of gasoline is only three to six months. During an emergency, gas stations run out of gas relatively quickly, so you’ll need to stay on top of your supply.
Best for: Budget-conscious homeowners who don’t need to power many appliances during an emergency.
Pros:
It’s one of the most affordable generator types, ranging from $500 to $3,000.
You can use a fuel stabilizer to increase the shelf life of gasoline for up to 3 years.
Gas is an easily accessible fuel.
Cons:
The cost of gas increases over time.
It has high emission rates.
Gas-powered generators are highly flammable, creating an electrical fire risk.
6. Natural Gas Generators
Natural gas generators are typically used in standby generators, connecting directly to your home’s natural gas line for power. These generators have excellent durability and will last many years as long as they are adequately maintained.
Best for: Homeowners seeking an effective, low-emission whole-home generator.
Pros:
This generator type produces lower emissions than diesel and gasoline.
It has a nearly limitless fuel source.
It easily connects to your home’s natural gas pipeline.
Cons:
It’s cost-prohibitive, costing $2,200 to $25,000.
Natural gas generators are vulnerable to extreme cold.
It has high maintenance costs.
It will not work if the supply cuts off during an emergency.
7. Diesel Generators
You’ll typically see diesel fuel in portable generators, but they can also work in standby or inverter generators. Diesel generators are durable and able to withstand cold climates. They’re also fuel-efficient and have a more powerful output than gasoline generators. Due to its ability to burn at low temperatures, diesel puts less strain on the generator’s engine.
Best for: Homeowners who live in cold climates and want a cost-effective, long-lasting generator.
