Electric changes at rest attract or repel each other. Moving charges (i.e. currents) also attract or repel each other. Therefore, work has to be done to keep two changes a certain distance apart or to move them with respect to each other. Similarly work has to be done to keep two current carrying conductors a certain distance apart or to move them with respect to each other. The energy associated with this work is called electrical, or, more appropriately, electromagnetic energy.
