Ignorant as it sounds, what 1kW of energy spent on having moved an object from point A to point B would be really spent on ? Is it, 1. acceleration /desceleration of all moving parts of both the engine and the object itself, and 2. overcoming by all moving parts (including electrons in wires) of all possible physical resistances. Am I missing something, and the pure fact that the body has changed position - "a work" was done - itself has required energy ?
