Horizontal axis, free yaw, self-regulated wind turbines which have strong, lightweight, fatigue resistant, fixed pitch, wood/GRE blades and exhibit superior performance a range of wind speeds. The blades are designed by employing defined inboard, midspan, and outboard airfoil profiles and interpolating the profiles between the defined profiles and from the latter to the root and the tip of the blades.
