Net energy yield matters, yes, but assuming a negative net energy (seems reasonable), we could still get the negative from renewable sources. Maybe I read too

Net energy yield matters, yes, but assuming a negative net energy (seems reasonable), we could still get the negative from renewable sources. Maybe I read too much science fiction, but I see a day in the future when we deploy autonomous technology at scale to deal with the greenhouse gasses and waste plastics of the fossil fuel era - little (or big) robots/factories that just take in energy from the Sun and use it to convert old waste into a manageable/useful form. Realistic? I dunno. But it's certainly more hopeful than the Malthusian dystopia of shaming people for staying warm and eating and traveling.
