Windmills Are NOT Like Dams

The video explains how windmills extract kinetic energy from wind, contrasting it with dams that use potential energy. It discusses the relationship between wind speed and energy extraction efficiency, highlighting that the optimal efficiency is achieved when the wind is slowed to one-third of its initial speed. This results in an overall efficiency of 59.259%. The video also notes that real-world windmills are more complex, and actual efficiency may vary due to engineering considerations.

What happens to the overall efficiency of a windmill if it slows the wind down below 1/3 speed?

According to the text, how much wind should a windmill mill for optimal energy extraction?
