A review on tidal energy technologies

Renewable energy sources have been in great demand over the past few years to meet our energy needs. But our existing energy sources churns pollution and depletes our environment. To overcome these problems, different renewable energy sources are used, and Tidal energy is considered the most efficient. In this, the energy is harnessed from the tides, and it can be used to meet our annual needs. However, it is not commonly used as it is inception. But with some research and development into the field, it can be used as a proper alternative for our energy needs. In this review paper, different methods and the devices used across the world for extracting tidal energy have been presented along with their advantages and disadvantages.
