In this paper an overview of a vertical axis wind turbine is specified. The performance of the Vertical Axis Wind Turbine (VAWT), current scientific status and new result during modeling work and future course of VAWTs were reviewed. It was observed that VAWT plays a critical role in the present power crisis. Wind energy has been recognized as a capable renewable option even though the full life cycle accounting shows VAWTs are profitable on a cost base or materials base over horizontal axis wind turbines (HAWTs), Currently the VAWTs do not generate sufficient electricity owing to some challenges which discussed in this paper. Lift driven VAWT ( Darrieus type), Drag driven VAWT (Savonius type) and hybrid of both (D+S) turbine efficiencies can be improved by adding the deflector arrangement that guides the wind towards the turbine blades. At current level a lot of researchers are going on. From the vast survey of the current scientific states of VAWT, it was observed that in India, Tamilnadu provide their place in this research area.
