Why not offer a small list of most relevant studies then? I can claim there are hundreds of studies and that MIGHT be true or not, offer a small glimpse is not only useful to teach readers looking for sources but also to prove I've done my research not just claim to have done it.
Beside that: I doubt. Cyclically we see promise, like IBM research that cyclically say they achieve a hyper-big advances in storage, something that "in the near future" can store Zettabyte of data in a rice grain etc, and I still have to see anything even similar. I have built my new home, just six years ago, well insulated, airtight, with proper ventilation, recently upgraded from passive temperature recovery (classic VMC with a paper heat-exchanger) to a heat-pump one, with a small p.v. and lithium storage, all electric again with heat-pumps etc. well it can potentially be "autonomous" IF I'm willing to waste a very big amount of money in a very big battery, much more space for solar panels to have enough energy to recharge the bigger battery AND still depending on a grid or generator for backup because a "reasonably bigger" battery (BEVs alike size) suffice to be comfortable just from a day to the next. Just two day means I need more land to harvest enough energy from the Sun. Oh and that being in France south Alps so in a significantly sunny place. Oh I'm just talking about a home, not a factory.
Sure we can already made let's say a glass production AND recycling factory 100% circular and renewable, we just need mountain hydro nearby. Enough, perhaps, if we are Norway with many mountains, water, little population. Or maybe Iceland with geothermal. Hardly for France.
So far we have seen MANY promises in terms of new battery tech, but essentially nothing really ready. Potentially in 2050 we can even have finally achieved nuclear fusion, witch is renewable formally. But we can't forecast that. It's a hope. It might be even computed in a game-of-if: if we finally discover a battery tech with this and that characteristic we can produce on scale with this and that intensity what time it take to spread it? It's still a study, but just an hypothetical one.
What we see so far is that FOR HOMES we can made single-family homes almost everywhere and power that with electricity only at rate "small enough" to be sustainable even at some arctic latitudes. This on scale means we need abandon dense tall-buildings since YES, we can made them TODAY with similar energy needs BUT we can't really upgrade them in the future, so to be future proof we need homes like cars, with a longer life-cycle but still small enough to be created and re-created after a certain amount of times (like a single human life) to align them with current needs and tech at any point in time. It might be doable if we agree to do so even before 2050 at least in western world, but I see no real push to do so. Just few do so on their own, no plans to design a new society seems to go in that direction, UN New Urban Agenda goes actually in the OPPOSITE direction. The rest are collection of dreams.
