Wind Energy Feasibility Dashboard

Wind power is calculated using the formula: P = 0.5 × ρ × A × v³ × Cp, where ρ is air density, A is swept area, v is wind speed, and Cp is efficiency coefficient. This cubic relationship between wind speed and power means that even small increases in wind speed result in significant power increases.

Generally, areas with average wind speeds above 5 m/s (11 mph) are considered suitable for wind energy production. Optimal commercial wind farms typically require winds of 6.5 m/s or higher. Small turbines can operate efficiently at lower speeds, but the power output increases dramatically at higher speeds.

Our CO₂ offset calculation is an estimate based on the amount of energy generated compared to conventional energy sources. We use an average emission factor of 0.7 kg CO₂ per kWh for conventional grid electricity in India. This may vary based on your local energy mix and the specific fossil fuels being displaced.

Horizontal axis wind turbines (HAWTs) have blades that rotate around a horizontal axis parallel to the wind direction. They are more common, efficient, and better suited for large-scale energy production. Vertical axis wind turbines (VAWTs) rotate around a vertical axis perpendicular to the wind, making them more suitable for urban environments and areas with turbulent wind patterns.

Turbine efficiency, represented by the coefficient of performance (Cp), indicates how effectively a turbine converts wind energy into electrical energy. Most modern turbines have efficiencies between 30-45%. This is limited by Betz's Law, which states that no turbine can capture more than 59.3% of the kinetic energy in wind. Higher efficiency means more energy production from the same wind resource.
