The United States has deployed the world’s largest tidal energy turbine, capable of generating 2 megawatts of electricity using the predictable motion of ocean tides. Installed underwater, the turbine functions similarly to a wind turbine—but with moving seawater instead of air. Tidal energy offers a major advantage over other renewables: absolute predictability. Unlike wind or sunlight, tides follow precise gravitational cycles, making them a reliable source of clean energy. While tidal power r
