This thesis presents a comprehensive assessment of Italy’s wind energy potential, integrating a wide range of turbine technologies, regulatory frameworks, and multiscale spatial analyses. The study covers the performance of small-scale vertical and horizontal axis wind turbines as well as medium and large-scale turbines up to 1 MW. Special attention is given to small wind turbines (5–10 kW) in both rural and urban environments, analyzing noise regulations, incentive schemes, and practical deployment challenges. Selected turbines are compared in terms of productivity and performance indicators under various wind regimes. A macro- and mesoscale wind resource analysis was conducted using hourly data from the New European Wind Atlas (NEWA).
