Marine energy refers to the energy derived from the ocean and its various movements, including waves, tides, and currents. This renewable energy source harnesses the natural power of water to generate electricity, making it a sustainable alternative to fossil fuels. Technologies such as wave energy converters and tidal turbines are designed to capture this energy efficiently. The potential of marine energy is significant, as oceans cover over 70% of the Earth's surface. By utilizing this abundant resource, countries can reduce their carbon footprint and enhance energy security. Ongoing research and development aim to improve the efficiency and affordability of marine energy technologies.
