There are three main variables that determine how much electricity a turbine can produce: Wind speed – Stronger winds allow us to produce more electricity.
Wind turbines use blades to collect the wind''s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are

Thus, the power available to a wind turbine is based on the density of the air (usually about 1.2 kg/m 3), the swept area of the turbine blades (picture a big
Now it''s a basic law of physics (known as the conservation of energy) that you can''t make energy out of nothing, so the wind must actually slow down
Energy harnessed by wind turbines is variable, and is not a "dispatchable" source of power; its availability is based on whether the wind is blowing, not whether
