And storage can help a lot even for conventional generation sources.

By combining 3 or more renewable sources, and having some storage, we can produce electricity more dependably than convention sources. This is because, renewable sources generally fail in small increments, and / or it can be predicted. Also, maintenance can be done progressively - small portions can be worked up, while the remaining systems keep going.
Solar closely matches the peak demand of power, for A/C. So, it is a good thing that it "only" produces power during the day.

Wave power is just about the most expensive way to generate power any one has yet to devise.
Wind platforms suspended over deep seas is probably a close second.
Ireland has or had the most successful wave power system. But it had to be reeled in and beached during rough surf.
These systems could be smashed by a Rouge wave.
The system was all hydraulic so when it was damaged hydraulic fluid would wash up on the beach.
