													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] |
