Savonius Vertical Axis Wind Turbine for Effective Generation of Power—A Review

In current scenario wind energy is the most favored nonconventional source of power generation due to several reasons. As per the International Renewable Energy Agency (IRENA), the global wind power generation in 2021 was 8.20 × 105 MW. However, India able to generate around 0.4 × 105 MW. The horizontal and vertical axis is the two main wind turbine types. The horizontal axis turbine is generally utilized to build a wind power plant. However, the vertical axis wind turbine (VAWT) can use to fulfill an individual power requirement. It can be installed at the top of the household building, too. Researchers are working on improving the performance of wind turbines. The vertical axis turbine has several types, like Darrieus, Savonius, Giromill wind turbines etc. As vertical axis turbine is for personal use, they can be commercialized in rural or remote villages where the population has relatively dense. Savonius VAWT is simple to construct and install. It can generate electrical power irrespective of conditional parameters such as wind velocity, direction etc. This article presents the utilization of Savonius VAWT to fulfill the need of the rural area.
