Wind Power Estimator

Harness the breeze. Calculate how much power a turbine generates at your location.

Requires at least 3-4 m/s to start.

Rotor Diameter 2 m

Blade span (Tip to Tip).

Turbine Efficiency 35%

Typical: 30-45% (Betz Limit is 59.3%)

Capacity Factor 30%

% of time wind is optimal (Onshore: 25-35%, Offshore: 40-55%)

0 W

Instant Output

~0 kWh / Year

The Power of the Cube:
Doubling wind speed (e.g., 5 to 10 m/s) increases power by 8 times! Location is everything.

Understanding Wind Physics

The power available in the wind is calculated by the formula: P = 0.5 × ρ × A × V³.

ρ (Rho): Air density (approx 1.225 kg/m³ at sea level).
A (Area): The swept area of the blades (π × r²). A larger rotor captures significantly more energy.
V (Velocity): Wind speed. Because this is cubed, a small increase in speed yields a massive increase in power.
