Increasing energy requirements accompanied by high fossil fuel emissions will lead to energy crises and the greenhouse effect in the future. These factors encourage the development of renewable energy. Hydropower can be one alternative energy to meet the energy demand. Hydrokinetic turbine is one of the latest technologies that utilize energy from water flowing in rivers, waterways, drainage in buildings, etc. This paper presents a review of hydrokinetic theory as an energy conversion system from flowing water with reference to the wind energy system. The most discussed type of turbine is a hydrokinetic savonius turbine with a description of the benefits, weaknesses, strengths, and conditions according to the application. Hydrokinetic savonius turbine is the most discussed turbine because of the ability of this turbine to work at low fluid flow rates in rivers and waterways. But the weakness of Savonius turbine is that it has low efficiency. Several experimental studies and numerical calculations by varying the design and parameters of the turbine have been carried out to improve its efficiency. The following parameters have been explained which affect the performance of hydrokinetic savonius turbines which are expected to be useful for future research to improve turbine efficiency.
