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] |
