An improved wind turbine device with energy storage comprises a turbine rotor with rotatable vertical shaft, at least one bearing for said vertical shaft, and multiple rotor vanes disposed symmetrically for rotation about the vertical shaft. Each of said multiple rotor vanes is substantially box-shaped with four solid sides and a front and rear side disposed in a radial vertical plane. The front side to each vane is substantially open faced and the rear side has an opening covered by a plurality of flaps. Each of said flaps is capable of moving with the directional passage of wind through the vane.
