Dunkelflaute in Europe - frequency

A 2021 published study revealed that in the connected grid of in eleven countries surrounding the North and Baltic Sea areas, it was found that almost all periods tagged as Dunkelflaute events (with a length of more than 24 h) are in November, December, and January for these countries. On average, there are 50–100 h (2 to 4 days with no windpower nor sunpower) of such events happening in each of these three months per year. Through an interconnected EU-11 power system, the mean frequency of Dunkelflaute drops from 3–9% (I don't know what that means, does that come from: 2 days/90 days=2% - 4 days/90 days=4%) for the individual countries to approximately 3.5% for the combined region. What is also relevant is the article on our EU-27 Synchronous_grid_of_Continental_Europe I need help. Sorry, no more time. Thy, SvenAERTS (talk) 23:19, 5 September 2022 (UTC)

Contradiction

The unsourced text declares a low sun/wind event shall be longer than one day to be called Dunkelflaute. Next paragraph (sourced) states that most events are less than one day. Unless a source is provided for the first statement, it should be removed. Votpuske (talk) 06:57, 22 November 2022 (UTC)

Apparently there is no quantitative definition - so I cited that Chidgk1 (talk) 07:38, 13 December 2022 (UTC)

Calculation

The text includes a calculation, 150h/8760h=1.5%. It is both arithmetically incorrect (should be 1.7%) and appears out of place: modern humans cannot survive without electricity for few days, no matter how small percentage of a year this interval constitutes. Unless a source tying the calculation to the subject of the article is provided, I think that the calculation shall be deleted. Votpuske (talk) 07:02, 22 November 2022 (UTC)

Is dunkelflaute now an English word?

If so we don’t need italics Chidgk1 (talk) 14:07, 21 February 2023 (UTC)

It's not in the Cambridge or Oxford Dictionary, nor the Merriam Webster one. In January of this year the Daily Telegraph used it, but defined it and called it a German word [1], as did The Guardian the preceeding month [2]. So no, I think it's still a German word used in novel circumstances in English prose, and only when someone is explaining what it is, and saying that it's German. -- Finlay McWalter··–·Talk 14:17, 21 February 2023 (UTC)

In 2021 I tried to rename the article to “dark doldrums” but by now I suspect dunkelflaute has entered the English language Chidgk1 (talk) 14:18, 21 February 2023 (UTC)

Lots of technical terms are perfectly valid, and are used in specific circumstances, without becoming "dictionary words" in the generally accepted sense. Wikipedia doesn't base its decision on what to call an encyclopedia article about whether it's a dictionary word or not. -- Finlay McWalter··–·Talk 14:28, 21 February 2023 (UTC)

I agree that not all English Wikipedia article titles need to be in the dictionary, but there's already an English term for this: Energy Drought. It's a technical term being popularized by the Pacific Northwest National Laboratory, a well respected research institution. In fact, Oregon Public Broadcasting among other websites and organizations have already published articles using that term. Why should English Wikipedia use a German term for something which already has an English equivalent? Cataleap (talk) 07:54, 9 April 2024 (UTC)

Just adding on to what the previous editor said, in case it's not already obvious: Pacific Northwest National Laboratory is a federal laboratory in Washington state, and generally uses American English. Of course with a lot of technical jargon like vitrification. ☆ Bri (talk) 14:13, 9 April 2024 (UTC)

I'm not aware of 'dunkelflaute' being used at all in British English, though it may be jargon within the energy industry. The standard term is 'anticyclonic gloom', which we get a lot of in England. --Ef80 (talk) 15:42, 12 December 2024 (UTC)

"designing electricity markets to incentivise clean flexible power."

Clean flexible power indeed is great, but what exactly is this "clean flexible power"? Either an actual solution needs to be at least hinted at, or the phrase removed, IMHO. Викидим (talk) 04:27, 14 December 2024 (UTC)

I amended to explain “flexible” as I assume readers know what clean power is Chidgk1 (talk) 06:36, 14 December 2024 (UTC)

Droughts

A new - and better IMHO - term "VRE droughts" is taking root in the research literature. We might consider at some point in time to have an independent article on it. The idea is treating the VRE as hydro (that is affected by regular droughts). See the poor planning effect for hydro in Equador in 2024 (BTW, where is the 2024 Ecuador electricity crisis?). Like for the hydro, the VRE planning should account for the cumulative damage over few consecutive years. For now, a section here would do IMHO. In the future, "dunkelflaute" mght end up being a section in the "VRE drought". Викидим (talk) 07:46, 14 December 2024 (UTC)
