The design and materials used in generators depend heavily on their fuel type. While new technologies (like solar generators) are emerging, gasoline, natural gas, propane and diesel are the primary fuel types.
Gasoline generators generally include portable and inverter generators. Gasoline is a familiar and easily obtained fuel, and a generator that uses it will produce the same noise and exhaust one might expect from a car or lawnmower.
As natural gas becomes increasingly abundant, it has become an attractive option for fueling standby generators. Natural gas-powered generators are a popular and cost-effective choice.
Clean-burning and boasting a high-BTU rating, propane is a good choice for standby generators. Propane has a long shelf life and can be stored in large quantities, with home delivery making it feasible for homeowners to fill their
Diesel is a reliable fuel source, and diesel generators have famously long lifespans. With on-site fuel delivery and low operating costs, diesel units are sound choices for whole-house generators.
