Wind Power Generation

Wind energy makes up merely 6% of the world''s electricity generation in 2018; yet, the international renewable energy agency (IRENA 2020) expects wind power to become the largest source of power generation in 2050, when about 35% of electricity supply may stem from wind energy (IRENA 2019).

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!
