Understanding Wind Turbine Profitability
Horizontal Axis (HAWT)
More efficient design (25-45% efficiency) but must be oriented toward wind direction.
Swept Area = π × r²
Vertical Axis (VAWT)
Can catch wind from any direction (15-35% efficiency) but generally less efficient.
Swept Area = diameter × height
Key Profitability Factors
Wind Speed
Power increases with the cube of wind speed. Even small increases in wind speed dramatically improve profitability.
Electricity Prices
Higher local electricity rates improve the financial returns of wind turbine investments.
Turbine Efficiency
Maximum theoretical efficiency is 59.3% (Betz limit). Real-world efficiency typically 25-45%.
Location and Maintenance
Optimal placement and regular maintenance are crucial for long-term profitability.
Wind Power Formula
Power Generation Formula
P = 0.5 × A × ρ × v³ × μ
P = Power generated (Watts)
A = Swept area (m²)
ρ = Air density (kg/m³)
v = Wind speed (m/s)
μ = Turbine efficiency (%)
Profit = (Power × Electricity Price) - Daily Costs
