Power is also proportional to the swept area of the turbine blades – so effectively proportional to the square of the blade radius. This helps to explain why ‘bigger is better’ in terms of catching the power of the wind, and ‘bigger’ also means ‘taller’ – so that more steady elevated wind speeds can be reached at higher altitudes.
We built a simple interactive web calculator to show this effect and estimate power output – and made the video below to share some facts on how wind turbines capture power from the wind, and explain how our calculator works:
Our free wind power estimator tool can be accessed on our Insyn platform (login required).
