A vehicular wind turbine system includes a vehicle having a propulsion system. The vehicular wind turbine system further includes a first wind turbine attached to the vehicle. The first wind turbine includes a plurality of turbine blades coupled to an electric generator. The first wind turbine is configured to convert energy from a relative wind into electrical energy via the electric generator. The system further includes a battery disposed within the vehicle to store electrical energy from the first wind turbine. The system further includes an electric motor configured to convert electrical energy stored in the battery into kinetic energy. The vehicle is to be propelled by at least the electric motor.
