The purpose of this paper is energy and economic calculations of the wind farm project and analysis of the environmental impact for this type of technology. For the selected type of wind farm, we have determined the location and calculated the amount of electricity generated on a daily and annual basis, the efficiency of converting wind energy into electricity and reaching the Betz limit. For calculations we used publicly available data from website renewables.ninja. Based on the energy data, economic analysis of the project was carried out. Considering revenues from electricity sales, investment costs, maintenance and operational costs, and decommissioning costs, we identified the project as economically ineligible. Using the ReCiPe hierarchist model, we carried out environmental analysis (LCA) of wind farms. The environmental indicators of a wind farm installed in Slovenia were compared with the indicators of wind farms in selected European countries. We also compared them with some other electricity generation technologies used in Slovenia.
