The problem with Ruinables is just one - they are intermittent.
I had started a Qn and Answer session with One Nut and he only answered the first one - he likely knew where it was heading.
Because they are intermittent, they are, by definition, incapable of providing base load power so they have to try and compensate by other means eg batteries / storage.
Then we head to another problem. It is simply NOT possible now to provide for storage for more than a few minutes / hours. When we have failure stretching into days (or a week eg in UK) a necessary by-product is blackouts. Nuclear will fix that BUT we have banned it in this country. So the only option is the oil/gas/coal. (BTW there was talk of green hydrogen and sundry other options BUT they are "pie in the sky" stuff right now. Begs the question, what idiots led us to this cliff face?)
