Types, storage facilities and performance of Vertical axis wind turbine: A Review

The focus on renewable energy has grown significantly over the last decades due to increased pollution, increased energy demand, and a lack of access to fossil fuels. Wind energy has been used for thousands of years since its inception and continues to evolve at a rapid pace. In this review paper, different types of vertical wind axis and the methods of calculating the power coefficient, the factors that affect turbine efficiency, and the different methods used to store electricity generated are discussed.
