An energy harvester simultaneously generates electrical energy from more than one source of natural fluidic motion, including wind motion and water motion. The energy harvester includes a wind turbine generator, a hydrokinetic turbine generator, or a wave energy generator. The impedance of the generators can be modulated to selectively control pitch, roll, and yaw motions of the energy harvester to stabilize external forces on the energy harvester and/or control the orientation of the energy harvester with respect to a wind direction or water movement direction. The generators may thus synergistically serve the dual purposes of electrical energy generation and energy harvester stability control.
