A wheel and wind power electric generator for a motor, comprising: an alternator that rotates with a wheel of a motor vehicle powered by an internal combustion engine, by an electric motor, or by other mean; an armature of an alternator that rotates with windvanes that rotate in an opposite direction from the wheel when the wheel is in motion, wherein the windvanes are spirally curved, so that they are concave in the direction that the wheel turns when the vehicle is going forward, causing the rotor and armature in the alternator to rotate in an opposite direction from the alternator to generate electricity, and the wheel and the windvanes are covered by a hubcap having slots through which air can move in when the vehicle is moving, causing the windvanes to rotate. The electricity generated may be stored in a capacitor or battery, and/or transferred to a power grid.
