VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs):
- Being omni-directional, some forms do not need to track the wind.
- VAWTs generally function better than HAWTs in turbulent and gusty winds. HAWTs cannot efficiently harvest such winds, which also cause accelerated fatigue.
- the gearbox of a VAWT takes much less fatigue than that of a HAWT.
- In VAWTs, gearbox replacement and maintenance are simpler and more efficient, as the gearbox is accessible at ground level, so that that no cranes or other large equipment are needed on-site. This reduces costs and impact on the environment. Motor and gearbox failures generally are significant considerations in the operation and maintenance of HAWTs both on and offshore.
