The article discusses some aspects of the renewable energy sources use, in particular, the problem of small wind power. A brief analysis of the development rates of wind energy in the world and in Kazakhstan is presented. The study is devoted to finding ways to optimize the blade of a wind power plant based on the Magnus effect, designed to generate electrical energy at low wind speeds. A cylindrical blade with a turbo-deflector has been developed to ensure independent starting of the blade rotation without the use of additional trigger mechanism. Laboratory tests of a cylindrical blade with a turbo deflector were carried out on a T-I-M wind tunnel at various flow regimes. The obtained dependences of aerodynamic forces on the air flow velocity at different angles of attack are shown.
