Horizontal axis wind turbines (HAWTs) have emerged as the dominant technology in modern wind energy technologies. In comparison to a vertical axis wind turbine (VAWT), a HAWT can achieve higher energy efficiencies, thereby increasing the power production and reducing system expense per kW of power generated.

In conclusion, both horizontal axis wind turbines and vertical axis wind turbines have their advantages and disadvantages. HAWTs are more efficient and scalable, but they require a tall tower and can produce noise pollution. VAWTs are more compact and can operate in low wind speeds, but they have a lower efficiency and generate less power.
