Gasoline or Diesel Gallon Equivalent (GGE or DGE)
|
1 gal = 0.74 GGE 1 gal = 0.66 DGE
|
1 gal = 1.00 GGE 1 gal = 0.88 DGE
|
1 gal = 1.12 GGE 1 gal = 1.00 DGE
|
1 kWh = 0.030 GGE 1 kWh = 0.027 DGE
|
Energy Comparison (GGE = Gasoline Gallon Equivalent)
|
gallon of propane has 73% of the energy in 1 GGE due to the lower energy density of propane.
|
1 gallon of gasoline has 97%–100% of the energy in 1 GGE. Standard fuel is 90% gasoline, 10% ethanol.
|
1 gallon of diesel has 113% of the energy in 1 GGE due to the higher energy density of diesel fuel.
|
A typical battery that is the same size as a gallon of gas (0.134 ft3), when used for transportation, can store 15.3% of the energy in 1 GGE. [6][7]
