Diesel vs. Natural Gas
Now that you have decided on a type/size of generator for your home, you might be wondering about the different fuel choices. There are several factors involved, including shelf life, cost, storage location, availability in your area, etc.
Propane and Natural Gas. The primary advantage of these is that no fuel storage is required. The generator is simply connected to your utility lines and draws fuel when it needs to. They are also both clean burning.
Diesel. Diesel fuel is common for bigger, commercial generators. They tend to be reliable and less expensive, but have a lower power output and require a storage tank, which can be unsightly sitting next to your azaleas!
Gasoline is the most common choice for portable generators. It is cheapest and available almost anywhere. However, gasoline has a short shelf life and is highly flammable. If you already have a propane tank for your heater or stove, a portable generator can be hooked right up to that, and propane is cleaner burning. Remember, under no circumstance should you run a portable generator indoors!
