Is wave energy the same as tidal energy?
No, they are different. Wave energy is obtained by some sort of float mechanism that is raised and lowered by the height of the waves. Tidal energy would be due to tidal currents that could be made to turn a turbine, or it could be obtained by building a barrage across the mouth of an inlet from the sea. At high water this would form a lake of seawater inside the barrage, which could then be let out through turbines as the water falls. An installation like this was built in France some years ago.
