The reason for this is that electricity generation, particularly the new generation of natural gas power plants (40% of our electricity comes from natural gas), is very efficient and the losses with high voltage transmission lines is very low. ICE cars are very inefficient in terms of how much of the energy in a gallon of gasoline is converted into motion. Electric motors in EVs convert a high percentage of the electrical energy in the battery to motion. You can also avoid the inefficiencies of having to transport gasoline to filling stations. While they take more energy to manufacture, if they are kept long enough there is a net energy savings. I believe the rational for EVs is that they use less energy.

Line losses are NOT very low!
