Neither is how to do this economically and reliably, while also surviving harsh ocean conditions. How machines take this motion of low-speed ocean waves with high energy content and convert them into the high-speed motion required for generators is not fully understood.

In short, ocean waves will move a WEC and that motion drives a generator that creates electricity. The surface portion moves faster than the submerged part, and the WEC converts that relative motion into electricity.Ĥ. One part rides surface waves and the other is a static or slower moving part below the surface or that’s connected to the seabed. Point absorbers are usually a two-part device. Grand-prize winner AquaHarmonics, for example, designed a point absorber, which demonstrated a five-fold increase in energy capture potential. The Wave Energy Prize, an 18-month competition that advanced the energy capture potential of WECs, highlighted a variety of promising devices. Because WECs extract energy from waves of all sizes that move in multiple directions, identifying the type of machine that can most-effectively do this work is a key goal of the U.S. Researchers expect typical full-scale WEC devices to be anchored miles offshore in deep water where wave energy is strongest. Ocean waves are converted to electricity with wave energy converter, or WEC, devices. This is where researchers aim to extract the energy. By the time a wave approaches land, it’s unlike any other. Ocean waves, on the other hand, interact with each other, the environment, and the weather. Regular waves, like radio or light waves, have a constant frequency and amplitude (see picture below). The waves range in sizes (from ripples to nearly 100 feet tall) and can travel thousands of miles before they reach land with almost no energy loss. The wind creates surface waves, like those that crash on a beach. The sun heats up air at different places around the globe, which creates wind that blows over ocean surfaces. Wind blows across the ocean, creating waves But how are ocean waves converted to electricity, exactly? It’s a process that begins with the sun:ġ. population living within 50 miles of coastlines, America can lead a new energy industry and meet a huge energy demand with reliable and forecastable clean energy. Researchers are working to harvest and convert that energy into cost-effective and reliable electricity. The energy of a single wave, for instance, could power an electric car for hundreds of miles.
Before they break on shore, ocean waves pack immense energy.
