Gasoline poses a fire hazard; propane does not. Propane also does not emit toxic fumes the way a gasoline generator does. If not used properly, a gasoline generator can cause carbon monoxide poisoning.
Unlike gasoline or diesel, propane can be easily delivered and safely stored on your property. During extended power outages, gasoline may be hard to get.
Propane can be stored for an unlimited amount of time. Gasoline often needs to be discarded because it degrades after being in storage awhile.
A propane generator will start more easily in very cold weather because it won’t thicken and gel like gasoline.
Propane produces significantly fewer greenhouse gas emissions than diesel and gasoline.
