Charts on the distribution of electrical energy in England.

We can clearly see the intermittence of renewable energies, which have to be compensated for by fossil fuels and sometimes electricity from France.

And France with its beautiful power stations and its all-electric policy without insulation, which must buy electricity from its neighbors in winter, do you speak of it?

How many does it buy, in "winter" (significant heating period from 1/10 to 31/03), in TWh?
And how many does she sell over the same period?
And how much gas consumed (therefore imported) over the same period?

By listening too much to the financiers who collect the aid and who have no interest in making it all sustainable, our two governments are downright in energy denial.
More bread on the board for future generations. : Shock:

The obvious failure of the German energy transition should alert French officials, who nevertheless persist in praising the magical virtues of wind and solar power ...

What about the “exemplary” German energy transition today?

- In 2019, a 62 GW wind farm (more powerful than the French nuclear park) produced only 128 TWh of electricity, or just under 20% of the country's total gross production;

- Of the 17 nuclear reactors condemned in 2001, 9 are still in service and are scheduled to be shut down by 2022;

- None of the traditional means of production, which can be mobilized at any time and totaling a power of 95 GW, has ever been stopped, the country counting on them until 2050.

- The exit of coal is announced for 2038!

- Better, according to the Federation of German Industry, it would be necessary, to reach quasi-carbon neutrality by 2050, a "wind" + solar "power of between 250 GW and 600 GW depending on the hypotheses, that is to say up to 10 times the current capacity!

- To be complete, the table must show the cost of a laborious phase-out, to say the least, estimated at 1000 billion euros by the Federal Minister for the Environment Peter Altmaïer by 2038: 700 billion euros of support for renewable energies; 300 billion euros for the modernization and subsequent development of electricity networks.

After 20 years of practice, the German REX thus provides proof that leaving nuclear power is only possible by massively resorting to gas, fuel oil or coal. But it also confirms that the obstinacy in pushing the aerogeneration and the heliogeneration to compete with the conventional thermal and nuclear generations is a ruinous technological and economic fight, which sooner or later becomes unbearable for the national economy, of which the citizen will end up. by refusing to pay the tithe.

So what can be done to force the French public authorities to no longer publicly and especially legislatively deny such obvious facts or, rather, to cynically pretend to deny them, going so far as to endanger an important national resource and social peace, in an industrial misuse deliberately carried out in haste?

Those professionals in the sector who will have the audacity to oppose, or at least to raise a credible threat, must know that they will render an invaluable service to their country, sparing it many vicissitudes. Because, the more our leaders go astray, the more the irreversible nature of their energy policy will be reinforced and the more the bill will be salted for the country. https://frontpopulaire.fr/o/Content/co1 ... e-annoncee

at the same time a nuclear park produces very little electrical energy compared to the thermal power installed with values ​​comparable to wind power.

IRT Jules Verne wants to recycle wind turbine blades

EMMANUEL GUIMARD New Factory on 24/09/2020

The Jules Verne Technological Research Institute (IRT), based in Nantes (Loire-Atlantique), has formed a consortium of industrialists aiming to create recyclable wind turbine blades using a thermoplastic resin from Arkema. Cost of the project: 18,5 million euros.

The Jules Verne Technological Research Institute (IRT), based in Nantes (Loire-Atlantique), will mobilize 18,5 million euros over three and a half years to reinvent wind turbine blades in recyclable mode.

Because, for the time being, this product is made of a thermosetting composite, without satisfactory recycling solutions.

The ambition is to produce them in thermoplastic materials, one of the virtues of which is to be recyclable. The project, called Zebra (for Zero Waste Blade Research), first associates the chemist Arkema and its Elium resin, a liquid monomer that polymerizes at room temperature. The first objective, by 2022, is to manufacture two prototype blades using this resin. One will be 62 meters long and the other 75 meters with integration of stiffeners. This thermoplastic resin had already been used in 2016 on 25-meter blades. There, the project changes scale since it is the entire life cycle that will be scrutinized.

For recycling, two avenues will be explored: the mechanical process of compounding (process allowing the mixing by fusion of plastics and additives) with reintegration of the elements in a new matrix. The other, thermal, is that of depolymerization. Because the heated resin becomes again a liquid monomer which can therefore be separated from the glass fiber.

The consortium is also mobilizing Engie, as a wind farm operator, the blade manufacturer LM Wind Power, a subsidiary of GE, Owens Corning, one of the world leaders in fiberglass, Suez, on the issue of recycling, and the Aquitaine Canoe technical center, specializing in composites. No date has yet been communicated on the marketing of this new generation of blades.

Commissioning of the Entre Tille et Venelle park in Bourgogne Franche Comté.
16 turbines of 2.5 MW.

Envision commissions 40 MW wind farm in France

November 3, 2020 evwind

Developed in the Burgundy-Franche-Comte region by Envision Group's French subsidiary, Velocita Energies, the Entre Tille et Venelle wind farm is thoughtfully integrated into the regional surroundings and will produce 107 GWh of clean electricity each year. This is equivalent to meeting the annual energy needs of 50,000 people.

With this wind farm in France, Envision anchors its presence in the region and contributes to the regional objective of 110 MW of installed capacity by 2020. With an installed capacity of 40 MW, the Entre Tille et Venelle wind farm achieves 36% of the target for this area.
......
The 16 EN131-2.5MW turbines installed at Entre Tille et Venelle each have a 2.5-megawatt capacity and 131-meter rotor diameter. These turbines were designed and adapted specifically for this wind region in France.

The idea that there is always wind somewhere and that it is enough to have wind turbines sufficiently dispersed and connected to produce, is a tempting idea but a false one.

The mix of wind power generation from remote areas in Europe remains highly fluctuating. Constructing enough power lines to carry wind power from areas where the wind is blowing at one point to those where it is not, would have limited effectiveness in spreading fluctuations in wind production (a significant use of controllable generators). demand and rapidly rising load would be essential, therefore always carbon dioxide emissions, even more if wind power spreads to the detriment of nuclear power).
This is what this study shows:

Good evening everyone,

Why refer to old studies from 2012?
Why not see for yourself with current data?
Just go to the official German website to see the random variations in wind + PV production.
Example for the month of August.
https://energy-charts.info/charts/power/chart.htm?l=en&c=DE&interval=month&source=sw&month=08
We see that the peaks of wind production do not vary randomly, but often coincide with PV production.
You can change the month to the right, but there's still that weird 24 hour period for the wind.

If one believes that it is enough to extend the production area, it is enough to collect the productions of Europe. It's tedious; banana did it for us.

If you have the patience, you can check, the data is public
