The document discusses several key factors that affect wind power generation and site selection for wind turbines. It explains that higher wind speeds generate more power as stronger winds allow turbine blades to rotate faster. It also discusses how air density, blade radius, and site characteristics such as elevation, wind shear, and proximity to structures influence power output and suitability for wind power projects. The optimal sites have fairly consistent wind flow at speeds within operational limits without too much turbulence or variation.
