Overview
Wind power output increases with the cube of wind speed. This cubic relationship means that small increases in wind speed result in large increases in power generation.
💡
Pro Tips
Site selection is critical; a location with 20% higher wind speed yields 73% more power.
Larger rotors (longer blades) capture exponentially more energy by increasing swept area.
Real-world efficiency (Cp) is typically between 30-45% due to mechanical and aerodynamic losses.

Fun Facts
"Doubling the wind speed increases power generation by 8 times (2³)."
"The theoretical maximum efficiency of a wind turbine is 59.3%, known as the Betz Limit."
"Modern offshore wind turbines can have rotor diameters larger than 200 meters."
