How wind speed affects turbine power production

The three wind speeds that affect turbine power production are called the cut-in, cut-out, and rated wind speeds. The "cut-in" wind speed is when the wind has reached a great enough speed to begin spinning the turbine blades – and thus begin producing power! This is typically around 3 meters per second (~7 miles per hour) for turbines
