An aircraft comprises an energy consumer 16b and an aircraft wing 3. The aircraft wing comprises a main wing element 5 and a movable wing tip 6 attached to a tip end of the main wing element. The movable wing tip can move relative to the main wing element to vary a span of the aircraft wing. The movable wing tip comprises an accumulator 16a configured to store energy and output energy to the energy consumer. The energy consumer may be located on the wing tip. The accumulator enables energy to trickle between the main wing element and the movable wing tip device whilst still providing a suitable power source to the device. The accumulator may be a super capacitor, battery, flywheel or hydrogen fuel cell.
