Wind Turbine Power Calculator

Calculate the theoretical power output of a wind turbine based on wind speed, blade length, and air density.

Input Parameters

m/s
m
kg/m³

Calculated Power Output

0.0 Watts (W)

This is the theoretical maximum power that can be extracted from the wind under ideal conditions. Real-world turbines typically achieve 30-45% of this value due to mechanical and aerodynamic limitations.

How It Works

This calculator uses the standard wind power formula:

Power (W) = 0.5 × air_density × π × blade_length² × wind_speed³

Wind power generation is highly sensitive to wind speed due to the cubic relationship. Doubling the wind speed increases power output by approximately 8 times!
