re: At least the half is different then solar. Solar operates during the day. Tidal power operates based on the movements of the tides, which shift around the day. Of course there would still be a lot of overlap, and since there would be periods when neither would be providing power, you would need power storage, or some other form of generating capacity to take up the slack, even if you had both solar and tidal power. (The same also applies for wind, not exactly the same as either solar or tidal, but overlaps with both, and there would be times when none of them provided power)

Exactly. To get uninterrupted power you still need a national grid and plants... preferably nuclear plants. Storage isn't an efficient option at this point. But with those alternatives you certainly need fewer plants... and less investment in plants.
