What it means: Ability of an energy burning facility to alternately utilize more than one kind of fuel, usually gas and oil.
See it in action: As the broad definition implies, there are all manner of applications for dual fuel generators, from power plants to at-home backup generators. These options allow the operator to select a fuel based on price and availability and are especially useful in areas where fuel supplies are unpredictable or varied.
Dual-fuel abilities are becoming increasingly popular in vehicles ranging from small cars to heavy trucks; allowing drivers to use compressed natural gas (CNG) where available, or fuel up with gasoline or diesel if no CNG stations are nearby. Running a vehicle on CNG where possible is a good choice for your wallet and the environment; a gasoline gallon equivalent of CNG costs approximately $2.00 while producing fewer emissions per mile driven.
