Fuel types
Choosing the right fuel type for your generator directly affects its efficiency, environmental impact, cost, and availability during emergencies. Each fuel type has distinct advantages depending on your home's energy demands, geography, and fuel accessibility.
Gasoline
Gasoline is the most common fuel used in portable generators. It’s easy to find and relatively inexpensive. However, gasoline is highly flammable and has a shorter shelf life (typically 3–6 months), which makes long-term storage less practical unless stabilizers are used. It also produces more emissions and is not ideal for prolonged outages or remote areas without nearby fuel stations.
Propane
Propane burns cleaner than gasoline, can be stored indefinitely in sealed tanks, and works well in cold temperatures. Many homeowners opt for dual fuel generators that can switch between gasoline and propane depending on availability. Propane tanks are widely accessible and are often used for grills, making them convenient for homeowners already familiar with propane handling.
Natural gas
Natural gas is an excellent option for standby generators because it connects directly to a utility gas line, providing continuous power without the need to refill. It’s clean-burning and cost-effective over time. However, it depends on utility infrastructure—if your gas line is down, your generator may not function.
Diesel
Diesel generators are more fuel-efficient than gasoline and provide excellent torque, making them common in rural and commercial applications. However, they’re heavier, louder, and less environmentally friendly.
Solar-powered
Solar-powered generators are a sustainable, quiet, and emission-free solution. Though they provide lower wattage output and are dependent on sunlight or pre-charged batteries, they are perfect for powering small devices during short outages or for eco-conscious homeowners seeking renewable energy.
On this page, we help you weigh the pros and cons of each fuel type, compare fuel costs, and determine which option aligns with your generator size, location, and emergency preparedness plan.
