Wind Energy Density Calculator

Compute the wind power flux (watts per square meter) available at a site for a given wind speed and air density. This is the gross resource: the energy passing through every square meter of rotor area before any turbine extracts it.

Wind Speed Height Adjustment Calculator

Convert a wind speed measured at one height to the equivalent wind speed at a different height using the power-law (Hellmann) model. Essential for projecting met-mast or weather-station readings up to turbine hub height.
