The Earth's oceans cover more than 70% of the planet's surface and hold immense potential as a renewable energy source. Unlike terrestrial sources, the ocean offers a variety of energy forms—tidal movements, wave actions, thermal gradients, and salinity differentials—that can be harnessed to produce electricity sustainably. As the world searches for cleaner energy alternatives, ocean and tidal energy have emerged as promising options in the pursuit of carbon neutrality and energy diversification.
