You are right,it's not that simple. Consider the inefficient
battery charger, the loss involved in the lines getting to your house,generating electricity from natural gas (example)requires burning fuel to convert it to rotary motion to drive a generator,to make electricity,this involves a loss as well. Now you "fill up" your car with electricity,but if you don't use it soon,you lose it,and need to be "filled up" again. Batterys lose their charge,are expensive, the system is inefficient,also somewhat dangerous,and ultimatly depends on a generating plant somewhere burning something.The 6000 lb. car uses more energy than a 2000 lb. car of course, a 150 lb. moped with a 50 cc. motor uses even less.

The bottom line is that the electric car used less energy to get from point A to point B. That is my only point. That point was being clouded here. Refining gas takes energy, transporting it to a station takes energy. Even pumping it takes energy. Gasoline engines are about 20 percent efficient but a gas turbine generator is much much higher. The gas motor uses more energy idling at a stop sign than an electric car uses to go 50 mph, I suspect.
