... most renewable energy sources is that it is independent of seasons or weather and is always constant. This makes power generation predictable and makes tidal power a reliable energy source. Marine current turbines convert the kinetic energy in the marine current into a more usable form of energy...

... data. INTRODUCTION Tidal energy, like wind and solar energies, is distributed across large areas and regarded as a potential renewable energy for the near future. The marine current turbines extract tidal energy from tidal flow by converting the sea water kinetic energy directly to mechanical power...
