... anyway - if I have "understood" correctly - it will take solar power plants in all latitudes, to follow and meet the demand of daytime human activity (the night buffer is already provided by the systems. buffer storage that we know ...)

Indeed Obamot, the intermittency of the solar resource can be canceled by combining 2 possibilities:
- energy storage
- a large geographic and temporal decentralization of the installations statistically always giving almost the same solar power on the network.

This also applies to wind power.

I also said to myself that to redress the finances of Greece while having a European vision, without siphoning off German finances, it would be good for France and Germany to unite to develop solar energy there. .

I think that a "Eurotrec" would already be not bad at all, both economically and geopolitically ... well, my opinion hardly matters.


Completely Remundo!
A European solar project would be a real economic and political solution!
The potential is enormous!
It is high time to start a smooth exit from nuclear power, because even starting now, it would take almost a century to dismantle everything ... and a hundred billion!
Couple the recent power stations with vortex towers and immediately close the garbage cans (..Fessenheim) whose condition does not cease to prolong operation (EDF to ask 15 years + !!!!, ASN to give its agreement for 10 years, but it's the state that decides) ...

Storage, yes. Geographical decentralization ..... With one caveat, the current which comes from a sunny area to reach an area in the middle of the night will make a few thousand km in High Voltage cables with the losses by Joule effect which go with it. .... with ultimately a lower shabby yield ....?

Compressed air with good heat exchange management becomes a very interesting solution, because the storage efficiency is 100%, low cost, decentralized, and ... usable directly in a vehicle ;-)

By the way, I'm looking for the energy efficiency of an air liquefaction installation: someone have any leads? nothing obvious yet ...

Oh no, online losses are between 5 and 10% on a conventional network (HT / MT / BT)

And with HVDC (high voltage direct current) lines, it's 3% / 1000km. Sending 1MW from Marseille to Brest would lose less than 2% in HVDC. Siemens and ABB are very advanced on the subject HVDC: high voltage direct current)
