A wind turbine blade is provided which includes a root section, a transition section, a conventional section and a tip section. The root section may include a chord length that is greater than a chord length calculated using conventional equations by a factor of approximately 1.3. The root section may also include a blade setting angle that is greater than a blade setting angle calculated using conventional equations by a factor of approximately 1.3. The conventional section may include a chord length and/or a blade setting angle that is approximately equal to a chord length and/or a blade setting angle calculated using conventional equations. In the transition section, the chord length and/or blade setting angle may transition from the chord length and/or blade setting angle in the root section to the chord length and/or blade setting angle in the conventional section. The tip section may include a winglet.
