Understanding Gasoline Gallon Equivalents
Gasoline Gallon Equivalents (GGE) measure the energy produced by alternative fuels compared to one gallon of gasoline.
According to experts Christine and Scott Gable, GGEs determine the amount of energy produced by alternative fuels, comparing it to the energy produced by one gallon of gasoline (114,100 BTUs).
Using fuel energy equivalents provides a comparison tool for gauging various fuels against a known constant that has relative meaning.
GGEs are the most common method for comparing fuel energy, measuring the BTU generated per unit of alternative fuel to the output of gasoline in a gallon equivalent.
Summary: GGEs help compare alternative fuels to gasoline.
