Apparatuses and methods are provided for a wind diverter at least partially encircling a wind turbine support column to direct the wind from an area around a wind turbine to the rotor blades of the wind turbine. The wind diverter may also reduce turbulence and increases the laminar flow of the airstream delivered to the rotor blades. Additionally, the wind diverter increases both the volume of air and the velocity of the airstream reaching the rotor so as to increase the rotor speed. Increasing the rotor speed increases the energy available to the wind turbine. Energy increases as the cube of the rotor speed and the increased energy produces an increase in the power generated by the wind turbine. The wind diverter also allows a wind turbine to begin producing energy at lower initial wind speeds due to the concentration of air.
