Wind power: for or against the wind?

[Leo Maximus]

... the service life must be able to be greatly extended beyond 20 years, knowing that the heavy structure is fixed, this will have a low carbon impact and will significantly reduce the material / kWh ratio ...

Exactly. The wind farm near my home is being renovated and the original foundations are being reused. The concrete from the wind farm is reusable ad vitam aeternam.
This is not the case with nuclear concrete. The millions of tonnes of concrete from Brennilis, Chinon 1, 2 and 3, St-Laurent des eaux, Bugey, etc ... have only been used once.

I wonder what cement for solar panels is?

When it comes to denigrating everything is good!

I wonder what cement for solar panels is?

There is differentiation between Cement and concrete ... Indeed, on large solar farms on the ground, foundations are needed to keep them in place ... The difference may be between reinforced and unreinforced concrete ....

After..The term cement .... May designate various resins and glues ....


Meaning of cement in English

cement noun [U] (GLUE)
a substance that sticks things together:

I am not trying to disparage.
The reuse of the bases must be possible for wind turbines of equivalent power. Are new installations always more powerful?

Here it is about offshore wind turbines.
Concrete blocks serve as anchor points for floating wind turbines?
The constraints are perhaps more important than on earth?

I actually agree that the document is not very objective and primarily defends local interests ...

The reuse of the bases must be possible for wind turbines of equivalent power. Are new installations always more powerful?

Indeed I have some doubts .... A wind farm of 20 years ago, it was machines of less than 1MW. Today an onshore wind turbine is at least 2MW, most often 3 to 4MW. Starting again from existing foundations to modify and extend them, possible? Examples welcome.

but a long time.
It is also the energy that emits the least CO2, just ahead of offshore wind power.

Everything is possible in theory, except that in practice, it is the opposite, wind power is much less reliable than expected, including its blades, which in addition are not recyclable.
The icing on the cake, neither wind power nor its maintenance are paid for by the electricity it produces. Wind power is paid for by the taxpayer, therefore to the detriment of the priority missions of states, such as education, justice or health.
As a reminder, the accounts for 2020 of the Beatrice wind farm in the North Sea:
Energy sale: £ 92,2 million
Renewable MWh grant: £ 281,3 million
Operating expenses: £ 127,4 million

Source? I am still surprised by the number of what you call "operating expenses"?

A book has just been released on the scourge of wind power.

"Does wind power have a real role to play in the "energy mix", is it just a deception that is juicier for its producers and for its promoters than for ordinary people? Are we living in the era of the wind merchants, in the bad sense of the word? Patrice Cahart would not want us to provide a false solution to the real problem of global warming. Knowing that a wind turbine operates on average, in our country, at only 24% of its power, it is essential to ensure the complement, and to resort to gas, which is polluting. Wind power is therefore a false clean energy, a false renewable energy.
Wind turbines, some of which now reach two hundred meters in height, ravage our landscapes, which are the living environment of the French, and one of the bases of our tourism.
In addition, wind power costs twice as much as that of nuclear power plants currently in service, the example of the United States of which shows that they can be extended for around XNUMX years. The realization of the current wind program would swallow up tens of billions which would be much more useful elsewhere (development of electric vehicles, insulation of buildings). So that you regain your freedom to think, Patrice Cahart gives you the real key to the problem".

Our historical jester entertainer of the king puts his foot in the dish and he's right.

WIND OF REVOLUTION - Annoyed by the development of the wind farm in France, advocated by the Minister of Ecological Transition, Barbara Pompili, the host Stéphane Bern denounced "an ecocide". The president of the Heritage mission blasted what is, according to him, "a deception" https://www.lci.fr/environnement-ecolog ... 87565.html

Review what Jancovici said in front of the National Assembly and nothing has changed, the ecocide continues with closed eyes.
