The inefficiencies are accumulative.
Yes, there are losses when you remove the energy from coal/natural gas/ oil etc to electricity. Then you have to transmit it through wires, step it up for transmission, step it down for domestic use, each transition has its own losses.
Then you store that energy in a battery of some type. Even with our friend who was promoting 'gerarators', there is no free lunch and more losses are encountered between what you put in and what you can get out. Finally you rely upon an electric motor to convert what you have left to mechanical motion.
In truth, electrics are not 'zero emissions vehicles' they are 'remote emissions vehicles'.
