No ?
And yet, Portugal spent 4 weeks in a row with more than 90% of its electricity from renewable sources.
Because no major media in France has focused on this type of information.
In the years to come, the share of wind and intermittent power will continue to increase, pushing back the others...
Yes, I had seen information like this, especially during a weekend.
But talking about Portugal, very well interconnected with Spain, makes little sense. It's a bit like talking about the production/consumption of Hauts-de-France within France.
Of course, barring any unforeseen incident, it will. It’s still the job of transport network managers.Indeed, and this is very good, renewables will eject fossil production from the system.
(-around 35% of production of combined gas cycles in Spain this year compared to last year for example)
Production, not necessarily capacity which will have to be maintained more or less, unless replaced by storage.
Electricity network managers, which are not just limited to transport, do a good job, without us ever talking about their difficulties and successes.
Thus, there was
a persistent rumor in previous decades which claimed that we could not/should not exceed a proportion of 20% of electricity from wind sources. However, in the Iberian Peninsula, as we can see at the end of 2023, there is clearly no problem.
Some experts have succeeded in spreading real fears on this subject: in 2004, in Denmark, this threshold was reached for the first time in Europe.
This country exceeded 10% in the year 2000, the logical consequence of a support policy started in the 80s; on this same date, in Germany, it is 2.5%, public support dates from 1991, it could even be when Angela Merckel was Minister of the Environment (to be checked)!
In 2004, the Danish political majority shifted, it was liberals who governed: paralyzed, they put a big stop to the deployment of wind power, then mainly on land.
However, it will resume, reaching 47% in 2019, and now 54%!
However, it is now part of an electricity network totally open to its neighboring countries: almost 100% of the electrical power of this small country can be imported/exported from one day to the next. .
Nothing of the sort in Spain, which in 2012 will also stop the growth in the deployment of renewable electricity, very flourishing until then, at the precise moment when the share of wind power reaches 20%.
With the consequence of the complete dezing of national manufacturers in this sector: Gamesa's wind power is sold to Siemens, the thermodynamic solar sector has still not recovered; ...
After having lived for 5 successive years at this level of 20% without this posing any significant problem, even in an electricity network isolated from the rest of Europe except with Portugal, the "crazy race" resumes during a change of political majority...
These setbacks must have given ideas in France, seeing the evolution of what remains of independent manufacturers in this sector...
We have returned more than ever to exclusively nuclear monoculture.
And yet, the Earth rotates... said Galileo to his opponents.At 27% this year in the Iberian Peninsula, but also in the United Kingdom and Germany. These are now large countries for which it has been demonstrated that this works, without problems of a prohibitive nature.
Until when ?
Because the objectives to be achieved for these countries are 40 to 50% wind power in their electricity mix in the decades to come...
We will therefore know quite quickly if, in at least 15 years, with the help of high-power electrolyzers placed on their electrical networks, "everything is going well" as the other would say...
The XNUMXst century will be spiritual... Malraux said.
We can add that it will also be... renewable...
