Wave energy turbines are renewable energy systems designed to convert the movement of ocean waves into electricity. These technologies capture the kinetic and potential energy produced by waves and transform it into usable electrical power through mechanical or hydraulic systems.
Ocean waves are generated by wind passing over the sea surface. Since oceans cover more than 70 percent of the Earth’s surface, wave energy represents a large and relatively predictable source of renewable energy. Wave energy turbines are designed to harness this movement efficiently.
Various engineering designs are used in wave energy systems. These include floating devices, oscillating water columns, and submerged pressure-based systems that respond to wave activity.
Wave energy turbines are typically installed in coastal waters where wave intensity is strong and consistent. These systems are often part of broader marine renewable energy projects.
