> There may well be a future where tidal provides better or more cost effective yields.
Based on what? With solar, we understood it was chemical science that would improve it. With wind, it was blade design, materials weight and durability, and generator technology. For tidal, what would improve that wouldn’t also improve wind? Improvements in durability, turbine, or generator tech would almost certainly also improve wind. Salt water will always be harder on equipment than air. Tidal forces are strong on large scales but on footprints similar to wind turbines, we aren’t talking about orders of magnitude more potential energy.
