Wind Energy Calculators

Free wind energy calculators.
Estimate turbine output, payback period, and compare wind vs solar.

Calculate air density from temperature, pressure, and altitude. Used for wind turbine power corrections, aviation, and aerodynamics.

Convert wind speed between m/s, km/h, mph, knots, and Beaufort scale. Includes Beaufort description and wind turbine cut-in reference.

Calculate how long a home wind turbine takes to pay for itself. Factor in installation cost, annual output, and electricity savings.

Calculate how much power a wind turbine produces at a given wind speed. Estimate annual energy output from rotor diameter and average wind speed.

Compare annual energy output and cost from wind and solar at your location. Find which renewable energy source suits your site better.
