Personally I've built my new home, insulation/airtightness/VMC/* and domestic p.v., being full electric and with a small lithium backup enough for passing an evening+night at minimum services (8kWh) + an emergency generator if needed... I doubt I can be considered a "anti-renewable activists", at least, I do that not because of an ideological cause but because I think that's good for me in practical terms (big initial investment, but ars covered for a not so marginal period of time and in case of troubles I expect in service disruption in the future), also I'm not one of the many that think to be environmental friendly because they live in cities and shop by feet few meters away, completely ignoring and rejecting if told, that such lifestyle demand a far big pollution they do not see, just outside their walled garden and sight, not much differently than the classic Orwell phrase: "Those who 'abjure' violence can do so only because others are committing violence on their behalf" but anyway... Also coming from an Italian WWII Partisan family (nephew of) I doubt I can be pro- any dictatorship, but exactly because of what I learn from my family I know how important is distinguishing "the real enemy", it's soldiers, some of them "without their knowledge", and it's own people...

The "so called green tech" can be theoretically cheap, but it's not really cheap on the market for various reasons, and while can work very well in certain sites can't do the same everywhere. For instance being in French south p.v. is effective, if it became legal here a hyper-small Pelton in the creek can push me toward real self-sufficiency for the MTBF of such system at least, but elsewhere?

In EU most people live in dense cities, no chance for effective and substantial energy improvement of buildings, their are tight and not "well oriented", there is not much room for renewable in general there. People living north if they do not have options for combined hydro+wind do not have much choices either, and they need far more energy to heat for a much bigger time period.

That's JUST to talk about private housing. Now if we also put on the table industry needs and EVs... We can't even with all nuclear, coal, oil, ... combined produce enough electricity for all. Not only: so far lithium tech is good enough for certain appliance BUT is not really recyclable (yes, experiments, startup do exists but they are experiments and startup not well established tech and developed industry at scale) and batteries does not last longer. If only they can last 20 years buying lithium storage, not just as a very expensive home-wide UPS, can be interesting for full autonomy, but that's not the case so far, and even if prices have fallen much in "historical terms" it's still too expensive for its lifespan. Even to stabilize the net it's then not an option, and that's a big problem if we really push renewable. Most people ignore the fact that to keep AC systems alive supply and demand MUST match, at a certain scale demand tend to be constant enough to offer network stability, below and above that it's extremely hard to keep the power on-line.

Long story short: I like much the idea, but I still have to see a fully working implementation for the masses or anything that can scale for industrial needs everywhere. Even at residential, individual home level, the sole practically usable at a certain scale today the balance is not really green: hot water is made with a heat-pump + classic resistance (and that's the best for solar since it's load remain almost flat, no phasing effects) it's not really complex but have a 10 years life expectancy and it's not much recyclable. Solar panels theoretically last longer, BUT practically if evolution continue it's not much interesting keep them more than 10 years, batteries last 5-8 years for EV, perhaps 8-10 for p.v. usage if not much stressed. Again really hard to recycle, mining what's needed for them is not cleaner than digging for oil and so on. Essentially we do not have anything really circular at actual population scale. We can be "long enough and recyclable enough" only for a far smaller population that being smaller can use certain resources on scale at a renewable level. If you do not propose a big genocide... There is no real "solutions", only different paths toward the unknown.
