This makes no sense. The triumph of using solar is to use it exclusively. I have explained in my own materials why it is physically not possible to use both (Energy of Earth, and solar). Look up "The energy polarity multiplier framework", both here and in Google. This tells you why failure to mathematically sign energy reveals many problems. If you have a problem with it, make the comment against the Medium story that I wrote defining the concept, and I will gladly engage with you there. Otherwise, I am sorry to say none of this proves anything technical, only that we disagree.

1/3 of solar energy put to use whilst still providing everything we could ask for being actually the best we can do is still a triumph, compared with being systemically locked into extraction by profit.

"unnecessary energy conversions" - how can you know what is necessary or unnecessary if you have never actually analysed the whole system?

If you think you have analysed it, show us where is your analysis?
