env.wind-power Calculator
Calculates the theoretical power output of a wind turbine from rotor diameter, wind speed, and a power coefficient using the Betz law equation. Wind power scales with the cube of wind speed — doubling wind speed multiplies available power eightfold.
Inputs
D
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
V
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Eff
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Hours
Reference formula or conversion factor shown for context.
Results
max power (MW)
Reference formula or conversion factor shown for context.
actual power (MW)
Reference formula or conversion factor shown for context.
annual generation (MWh)
The result expressed on a per-year basis.
homes powered
Reference formula or conversion factor shown for context.
capacity factor
A dimensionless multiplier applied in the calculation.
