Wind turbine apparatus is described for converting wind energy into electrical energy. The apparatus includes a rotatable central shaft, a plurality of rotor blades attached to the central shaft, and a plurality of convex airfoils spaced around the periphery of the rotor blades. The ratio of the number of rotor blades to the number of airfoils is at least 1.25 to 1. The size of the apparatus may vary, and the apparatus is useful in a variety of applications and environments. It is very efficient in converting wind energy to electrical energy. It may be operated even in very high wind conditions.
