And at night, that's kind of the point of it.
During the summer. Even then it doesn't scale and is an ecological nightmare given its footprint. Best designs give 10 hrs of operation per 12 hours of strong daylight. This means less than 8 hours during the winter anywhere except the equator.
Why do you keep translating "renewables" to "solar, just solar, literally only solar considered, no other sources of renewable energy whatsoever"?
I don't, but that doesn't matter. Geothermal is limited in use case. Hydro is worse for the environment than coal unless you make it a hydro battery, and then you only have so many places you can build it, and wind is naturally unreliable by definition. Solar is the most consistent renewable, and the cheapest, and it's useless on average half of a day.
Renewables are great, and eventually when we figure out perfect energy storage using hydrogen or other super common material based battery they'll be almost good enough for most use cases on earth.
Until then, though, and for all future applications, fission and fusion are going to be needed.
Edit: also lol if you think wave generators are anything but an express way to shed micro plastics into the ocean.
Out of interest, would you care to share with us your PhD thesis? I have to assume it's in a field like energy grid engineering, given how confidently you're disagreeing with CSIRO and the scientists who work for it.
