Renewable Energy

Basic

Rotor Swept Area

Area swept by turbine blades, which sets its power potential.

Formula

A = \pi r^2

Variables

ASwept area (m²)

rBlade length (m)

Example

r=50 m: A ≈ 7854 m²

Did You Know?

Doubling blade length quadruples the swept area — why modern turbines keep growing ever larger.
