Leopold Kohr explained the fundamental underlying causes in the 1950's, this led to the "small is beautiful wave" twenty years later, and we now rediscover them.

There is at least a project aiming at specifying a protocol (and at developing associated tools) defining how developers can be paid, in order to let users support what they use (even through dependencies) according to their will and withou

Those are effects of the Industrial Revolution, which led to the current climatic challenge. What a success!

There are safety-related limits (power modulation proportion, duration of a pause needed after each modulation, modulations frequency...), and the very combustible status is a major parameter. Pertinent document (French ahead!): https:&#x2

Such a major parameter wasn't considered 60 years ago... others ignored pertinent facts probably exists. My point was about what we (for the time being) ignore, albeit it is pertinent. They "considered" such facts using a so

Area: offshore wind is by far the most promising renewable (excellent aggregated power and load factor). Predictability: spreading out production units, using a mix (wind, solar...) and storage are key. https://www.imperial.ac.uk

Those reactors in China (at the Taishan powerplant) were completed at a (officially) 60% overcosts, and were 5 years late. One of them is shut down since mid-2021 after an incident (leak).

Nuclear isn't (historically) "statistically the safest", and any major accident or hot-waste-related problem may worsen its case. https://ourworldindata.org/safest-sources-of-energy

Uranium (as a nuclear fuel) cost may never become prohibitive, however ore grade may prove a major challenge as its decline leads to more emissions: https://news.ycombinator.com/item?id=30660554

With such a (realistic) approach nuclear is condemned because its production costs (LCOE: https://www.lazard.com/perspective/lcoe2020 ) are higher than renewables' (and the gap is enlarging). Therefore renewable

Even nuclear needs fossil-fuel backup, as building enough reactors to cope with peak demand would be way, way too expensive. Even a massively-nuclearized France produces 7% to 12% of its gridpower thanks to fossil-fuel plants. French offici
