Here are a few of the many advantages a propane generator has over a regular old gasoline power plant. After reading this, you will be hard pressed to make do with a gas burning generator!
First thing we will discuss is how much cleaner burning the fuel is when you use propane. The toxic fumes and atmospheric pollution is much higher from gasoline than it is from propane. Propane by itself is odourless and non toxic. The smell associated with propane is added to it to assist in finding or noticing leaks, and it is called Mercaptan.
Another big advantage to propane generators is storing fuel in cylinders versus in a jerry can. Storage of small amounts of gasoline in plastic jerry cans is a real pain, as well as a fire hazard. Comparatively, a propane bottle such as the ones used on barbeques rarely leak. In any case, a propane leak will disipate if it is in an open area, whereas a gasoline leak will leave a big stain on the floor or ground.
If your house has a propane tank to supply the furnace with fuel, then a propane generator can be plumbed in directly to the household propane. Then, in the case of an emergency need for electricity, your generator can quickly swing into action and will have the large propane tank as fuel. This would enable a household to maintain power for extended periods of time with their standby emergency generator. Propane generators are also more cost effective, depending on how much propane costs at the time.
