Wave energy converters (WECs) harness the power of ocean waves to generate electricity. Innovations in WEC design, including oscillating water columns, point absorbers, and attenuators, have significantly improved their efficiency and reliability. Additionally, the integration of energy storage systems, such as batteries or hydrogen production facilities, enhances the dispatchability and economic viability of wave energy. As research progresses, wave energy may become a major contributor to the global energy mix, especially in coastal regions.

3.2 Tidal Energy:
Tidal energy is another promising form of renewable energy that utilizes the gravitational pull of the moon to generate power. Innovations in tidal turbine design, such as horizontal axis turbines or vertical axis turbines, optimize energy extraction from tidal currents. Additionally, the development of tidal lagoon projects, which harness the potential energy of water trapped in enclosed areas, offers a more predictable and constant source of clean energy. Tidal energy has the advantage of being highly predictable, making it a reliable and consistent power source.
