1. A blade for a wind turbine, comprising:
a suction side and a pressure side extending between a leading edge and a trailing edge;
an energy distribution system having at least one external portion protruding from the suction side or the pressure side through a shell hole;
at least one aerodynamic element attached to the suction side or the pressure side for aerodynamically shielding the at least one external portion of the energy distribution system;
at least one active aerodynamic device; and
a pneumatic actuator;
wherein the energy distribution system is a pressure supply system activating the at least one active aerodynamic device provided on the suction side or the pressure side, the at least one active aerodynamic device being moved by means of the pneumatic actuator fed by the pressure supply system, the pressure supply system comprising at least one external duct protruding from the suction side or the pressure side, the at least one aerodynamic element being attached to the suction side or the pressure side for covering the shell hole and at least one external duct.
