A wind turbine blade is provided which is attached to a hub of a wind turbine. The wind turbine blade includes a spine. The spine can have various cross-sections, such as square, rectangular, triangular, "I" beam, or other suitable cross-sections. An attachment member is connected to one end of the spine. Ribs are provided and the spine extends through apertures in each of the ribs. A facing is attached to the plurality of ribs. The facing forms a convex surface on one side and a substantially flat surface on the other side. The flat surface is at an angle of between 24 degrees and 28 degrees from a plane perpendicular to the axis of rotation of the blades near a proximal end of the blade and the flat surface is at an angle of between 8 degrees and 12 degrees at the distal end of the blade.
