Wind power: for or against the wind?

[GuyGadeboisTheBack]

No reasoning, no proof ... Pure ideological blah.

It is today the only field of ecologism.

No, that's your crusade, I was talking about the article, incredibly poor.

Increasingly giant, VESTAS now offers a 15 MW offshore wind turbine!

15MW wind turbine is record 260m high

February 12, 2021 // By Nick Flaherty

The V236-15.0 MW wind turbine from Vestas in Denmark is aimed at offshore energy generation as the sweep of the 236m long blades covers 43,000sq meters.
Vestas in Denmark has launched a 15MW wind turbine that will be a record 260m high, taller than the Commerzbank Tower in Frankfurt and approaching the Shard in London

The V236-15.0 MW wind turbine is aimed at offshore energy generation as the 236m long blades cover 43,000m 2. The previous record was held by GE's 14MW Haliade-X, with a 220m blade. Both GE and Vestas are also part of a Danish project to produce large composite blades that can be recycled.

“Introducing our new offshore platform is a huge achievement for everyone at Vestas, as it marks a big leap forward in a very important journey,” said Henrik Andersen, CEO of Vestas. “Offshore wind will play an integral role in the growth of wind energy and the V236-15.0 MW will be a driver in this development by lowering levelized cost of energy thus making our customers more competitive in offshore tenders going forward.”


The 15MW wind turbine will use power technology from the existing 9MW and EnVentus turbine platforms, using a modular approach to scale components.

Combining the wind industry's largest rotor with the highest nominal rating, the 15MW design reduces the number of turbines in a wind park. For example, for a 900 MW wind it boosts production by five percent with 34 fewer turbines compared to the V174-9.5 MW version. The new design improves the partial-load production, resulting in a more stable energy production.

Very funny: wind turbines without CO2 to fight against global warming ...
... The wind turbines froze. Half of Texas' wind capacity (12GW out of 25), and other states, is shut down.

"Frozen wind turbines hamper power generation in Texas, state power operator says"
Such "propaganda" from the operator, to shoot himself in the foot, amazing!
If you have less ridiculous as an argument, I remain interested.
Or, according to the green religion, should we report the problems of energy production only when they concern oil or nuclear? Damned, I forgot to convert!

The map was very clear. In case of reading difficulty, contact me.

You haven't understood anything yet, Tryphon. I didn't say it was wrong, I said it was illegible and therefore propagandistic since nobody got it right. The words are clearer. And prove you are right. This is a world!

We can not count on it when there is no wind but also when it is cold, what a hoax, for once I join you Exni

half of Texan wind turbines have frozen over in recent days, causing the share of wind-generated electricity to drop from 42% to 8%. https://www.courrierinternational.com/a ... -americain

[GuyGadeboisTheBack]

It's not as if this kind of temperature was exceptional and mainly due to climate change ... nooo ... The day we meet the same problem in Saudi Arabia, Izy will throw the same nonsense ... He prefers nuclear accidents , without a doubt. Anyway, apart from your (false) climatic posture, Tryphon and you are twin brothers, the other being a step above you in terms of intelligence (Alas).

There is the Sortland wind farm in Norway ...

Under certain conditions, cold mixes with humidity and thus block devices ...

Energy. The crisis in Texas, proof of the “dilapidation” of the American electricity grid

Whose fault is it ? While millions of Texans have faced massive power cuts for several days caused by a historic cold snap, conservative circles point to a failure of renewable energies. But for a large part of the press, the crisis illustrates above all the vulnerability of America's energy infrastructure.

How did the “mighty Texas, America's powerhouse” fail to this point? According to CNN, this is the question many Americans are asking in light of the massive power cuts in the southern state of the United States, hit by a historic cold snap.

As of Tuesday, February 16, the authorities had communicated "no timetable for restoring electricity" to the more than 3 million customers who are deprived of it in Texas, reports The Dallas Morning News. A situation which triggered a political confrontation, in a state where energy independence is a matter of “pride”, underlines the Associated Press.

Local elected officials notably demanded the launch of an investigation into the action of the regulatory authority for electricity distribution in Texas, whose decisions affect more than 26 million consumers.

On the Republican side, the culprit is all found. “This is what happens when you force the grid to depend partly on the wind for energy,” tweeted Republican congressman from Texas Dan Crenshaw.

An opinion shared by The Wall Street Journal which points to the “excessive” dependence of Texas “on wind energy”. According to the conservative daily, half of Texan wind turbines have frozen in recent days, which has caused the share of electricity produced by the wind to drop from 42% to 8%.

For thirty years, Democrats and Republicans have favored subsidies for renewable energies, "which has made the network less stable," adds The Wall Street Journal.
Wind, natural gas and nuclear in difficulty

Arguments swept away by The Texas Tribune, which assures us that, from natural gas to wind turbines via nuclear, “all sources of electricity production have been put in difficulty”.

For The Washington Post, the Texas problem is not about “engineering” or “frozen wind turbines”, it is economic:

In the name of deregulation and free competition, Texas has created an electricity grid that prioritizes low prices over reliable service.

An approach that ended in a “shipwreck” on the local energy market: the wholesale price of electricity rose from $ 22 to around $ 9 per megawatt hour in Houston on February 000 and 15, reports the US capital daily.

The current episode underlines the “great vulnerability” of this electrical network, adds The New York Times. The New York daily recalls that Texas's electrical infrastructure “operates largely independently from the rest of the United States” and that it is especially designed to respond to the summer heat waves that push millions of Texans to their air conditioning on.
Like “the last years of the Soviet Union”

More generally, electricity grids are “strained” by climate change, says The New York Times. And the failures observed in recent days in Texas and, to a lesser extent, in Oklahoma and Louisiana, show, like the chaos that hit California in the summer of 2020, “the state of dilapidation of the American electricity infrastructure. ”, Laments The Washington Post.

The daily quotes in particular an energy specialist from the University of Houston, Edward Hirs, to whom the lack of investment in the production of electricity in the United States reminds us of “the last years of the Soviet Union, or the oil sector today in Venezuela ”.

In short, the real problem, assures The Washington Post in a column, is that the modernization of the electricity network to make it more resistant, more efficient and more secure represents “the worst of the challenges” for the political class: it is a subject “ complex, expensive and easy to ignore ”.

Note in passing that the share of wind power is 10% in winter and not 12GW out of 25. Thank you, Tryphon, and thank you also to Izy for your precious collaboration in blind neoliberalism.
