To examine the aerodynamic noise produced by small wind turbines, this study predicts and measures the aerodynamic noise from a 10 kW wind turbine. The numerical predictions include the turbulence ingestion noise, turbulent-boundary-layer trailing edge noise, and trailing edge bluntness noise....

This paper introduces a new approach to the study of the socioeconomic impact of renewable technologies through the analysis of the reinforcing effects of the expansion of this industry and the specific characteristics of the employment along the value chain.

This paper presents semi-empirical models for estimating global and direct normal solar irradiances under clear sky conditions in the tropics. The models are based on a one-year period of clear sky global and direct normal irradiances data collected at three solar radiation monitoring stations...
