A wind power plant includes four main elements: a foundation ( 29 ), at least one supporting structure ( 21 ), a carrying construction ( 23 ) having a vertical axis ( 25 ) and being rotatable around the vertical axis, and at least one rotor ( 45 ), ( 49 ), ( 52 ) positioned on the carrying construction. The rotors can have horizontal, vertical, and inclined axes of rotation in different combinations. Each rotor has at least two blades ( 53 ) arranged along its axis of rotation. Since the rotors used in the invention have a small diameter, the wind power plant can produce energy under high and low wind speeds, consequently producing more energy per year than known wind turbines. Also, because the rotors have rectilinear blades for their manufacture expensive composite materials and complicated expensive equipment are not required. For these reasons the wind power plant of this invention will produce energy at lower cost.
