No, China bets on renewable energy way more than on nuclear: https://news.ycombinator.com/item?id=31466725 Note: the AP1000 isn't French: its a Westinghouse reactor. This Westinghouse division filed for Chapter 11, see

Indebted, indeed... If you really think Kazakhstan can disobey to Russia then let's agree on not living on the same planet.

In China nuclear's progress is in fact quite slow: 2 to 6 new reactors/year. Nuclear now produces 6% of the electricity, and the plan is to reach 7.7% by 2035 https://en.wikipedia.org/wiki/Nuclear_power_in_Chi

As far as I know in Germany any industrial equipment has to be insured for good, including any civilian nuclear operation (not, as in most other nations, with very low ceiling).

Nuclear isn't better on this account: https://www.reuters.com/business/energy/exclusive-us-utiliti... This is even true for France, as most of its uranium comes from Kazakhstan.

I think so. For each and every attribute (of anything) there is an "interval" of proper values. Too few/too much is dangerous. A recent pertinent thinker was: https://en.wikipedia.org/wiki/Leopold_Kohr

This seems pertinent to me, and is a quite old concept. Jacques Ellul, for example, posited that our "technical system" aims at efficiency to the point of engulfing everything, in a detrimental way because (composed with physic la

We can transmit electricity over long distances thanks to (U)HVDC and it is more and more applied: https://en.wikipedia.org/wiki/List_of_HVDC_projects

Yes, as electricity only globally provides at best about 25% of final energy all this is misleading when it comes to the 'big picture'. Usage profiles are indeed pertinent: Australians probably don't need dissipate energy in

As the comparison was set with Australia (as a whole nation), I considered Canada as such.

Canada is a very different case: electricity sources are 2/3 renewables, mainly hydro (~60%). Nuclear: ~15%

Well put. The cultural bias may be approximated by comparing results obtained from English-as-the-mother-language speakers to those produced by people with less and less command of the language.

Emissions: those are present (now) emissions. The paper I quoted (read above) is about future emissions (median up to 110g CO‐eq/kWh by 2050), bumped up by lowering ore grades. Recycling: however breeders are AFAIK the most efficient

I'm not a specialist. If I understand correctly "breeder mode" depends upon fuel composition (which actinide/isotope, in which proportion...). Non 'fast-neutron' mode is dubbed 'thermal' and seems l

True, however those materials needed to manufacture wind turbines, solar panels... can be recycled, most of them infinitely (at human scale), and it more and more becomes either legally or economically unavoidable. Uranium isn't recycl
