Wave energy converters are devices designed to capture the energy produced by ocean waves and convert it into usable electricity. They work by harnessing the up-and-down motion of waves, which can be transformed into mechanical energy and then into electrical energy through various technologies. These converters come in different designs, including point absorbers, oscillating water columns, and attenuators. Each type has its own method of capturing wave energy, but all aim to provide a renewable energy source that can help reduce reliance on fossil fuels and contribute to a more sustainable energy future.
