Ocean energy refers to the renewable energy derived from the ocean's natural processes. This includes energy from waves, tides, and ocean thermal gradients. Technologies harnessing this energy can convert the movement of water and temperature differences into electricity, providing a sustainable power source. The potential of ocean energy is significant, as oceans cover over 70% of the Earth's surface. Various methods, such as wave energy converters and tidal turbines, are being developed to capture this energy. Utilizing ocean energy can help reduce reliance on fossil fuels and contribute to a cleaner environment.
