The article presents an analysis of the use of Savonius wind turbines with vertical axis of rotation. The first part presents an analysis of the literature with the dentification of the properties of the basic atmospheric parameters related to the air movement referred to as wind. Used mathematical descriptions used in the analysis of air movement and enabling the identification of basic thermodynamic parameters of wind turbines with a vertical axis of rotation were presented. Then, the historical background of the development of wind turbines with a vertical axis of rotation was presented, and constructions of this type currently used were described. Proposals for modification of the configuration and design of Savonius rotors and the impact of these activities on their efficiency were analyzed. These issues were presented in relation to the experimental work carried out in the international research centers. Obvious advantages and disadvantages of using this type of equipment in the field of wind energy were indicated.
