Enter the radius, wind speed, air density, and efficiency factor into the calculator to determine the total power output from the wind.

Wind Power Formula

The following equation is used to calculate wind power.

P = π/2 * r² * v³ * ρ * n
  • Where P is the power in watts
  • r is the radius of the turbine
  • v is the velocity of the wind moving through the turbine
  • p is the air density (1.2 kg/m^3)
  • n is the efficiency factor (typically 40%)

Wind Power Definition

Wind power is defined as the total amount of energy per unit of time that a wind turbine can generate through the kinetic energy of moving air.

Wind Power Example

How to calculate wind power?

What is wind power?

Wind power is energy generated through capturing kinetic energy in moving air masses. This is captured typically by a wind turbine.

What is a wind turbine?

A wind turbine is a device that turns the kinetic energy of wind into electrical energy that can be distributed to the electrical grid.

What is the maximum efficiency of a wind turbine?

The maximum efficiency of a wind turbine is 59.26%.
