The wind turbine power output is directly related to the swept area of its blades. Increasing the radius of the wind turbine or the longer the blades would result in an increase of the power that can be extracted from the wind. With larger blades, a lot of wind force will be applied on the wind turbine blades. These blades need to be built to be strong in order to withstand higher levels of centrifugal and varying gravitational loads.

So what is the relationship between the wind turbine swept area and the power output? Looking at the equation for output power you can see that the capture area of the wind turbine blades is utilized to calculate how much power can be extracted from the wind turbine.

**Swept Area and Output Power Relationship:**So what is the relationship between the wind turbine swept area and the power output? Looking at the equation for output power you can see that the capture area of the wind turbine blades is utilized to calculate how much power can be extracted from the wind turbine.
