A rotor blade for a wind turbine having a blade root, a transition piece and an aerodynamic part, wherein the blade root essentially is optimized for fixation of the blade to the hub and the aerodynamic part essentially is optimized to extract energy from the wind and wherein the transition part realizes a beneficial transition between the blade root and the aerodynamic part. The rotor blade can perform better both aerodynamically and structurally compared to a classic design when the blade part located near the axis, approximately the part between 0% L and 50% L is provided with one or more of the following characteristics: more twist than usual, attached flow stimulating measures at the suction side, flow blocking measures at the pressure side, thicker profiles than usual, a triangular shape of the profile back and back twist.
