Abstract
The world is making its transition to sustainable renewable energy. Researchers have studied the behavior of tidal current turbines (TCT) under various conditions as well as numerous approaches for application. Using Betz limit theory, many studies were conducted to analyze the usage of TCT and modification of TCT for all the living things without affecting the environment. With regards to the design development of TCT, the various technological trends such as yaw drive mechanism and horizontal axis turbine have been discussed. The paper has reviewed the latest update on various TCT energy generation capacities by different companies at differing locations.
