Power extracted from tidal water-level differences or tidal currents. Astronomical timing is predictable, but output is not constant. Basin geometry, flow changes caused by extraction, environmental effects and connection infrastructure constrain practical resources; a local undisturbed-flow power density is not a whole-channel extractable-energy estimate.
Tidal power is a form of renewable energy that harnesses the energy generated by tidal movements in oceans and seas. It primarily involves two mechanisms: tidal stream and tidal range. 1. **Tidal Stream Energy**: This method captures the kinetic energy of moving water during the rise and fall of tides. It uses underwater turbines that generate electricity from the tidal currents, similar to wind turbines that capture wind energy.
