Are you telling us something?

I think most historians agree with OME.

Here is a page from the specs of the Vestas V126-3.3MW 50/60Hz https://www.rettetdenbuschberg.at/wp-content/uploads/2016/11/10_V126-3.3-Allgemeine-Spezifikation.pdf?utm_source=chatgpt.com Page 27 Certainly, derating does begin at around 30 degrees but at a little over 40 degrees it is only losing a small amount and does not cut out fully until 45 degrees. I would suggest that there would not be too many days exceeding 45 degrees in locations where wind farms are generally built.

Links?

I present what I posted with a high level of confidence that it is correct; however, feel free to present verifiable information to the contrary. I would also be happy to post the detailed links supporting what I posted. It would be surprising if wind turbine manufacturers did not design specifically for different environments. You would expect turbines made for offshore use to be differently designed than those for onshore use or in deserts.

The newer ones still had a hard stop at 40. The derating started earlier. Blades dont make a difference to coolant temp, maybe the fan at the front can be made to blow more air over the radiators😁

Have you ever shut down and then started a coal fired power station? I am sort of bored answering this.. so will let AI do the talking: I don't see any excellents for coal. The one thing that renewables is poor at, ironically can be moderated by the answer to the last thing on the list. The key being the older ones, and the design for European conditions (which under current climate change, at least in the southern half of Europe is fast approaching Aussie type weather anyway). The blades and turbines design can be changed to meet Aussie requirements relatively easily; Coal, not so easy to refine the design any more that it is.. You can add scubbers and makle the boilers a bit more efficient, but I doubt they would advance too far from where they are now.

Unless they have changed in the ladt 4 years. Fot the wtg i worked on the older ones use to be a harx stop at 40 degrees, but often use to stop on hot gen coolant or converter temp. The newer ones would start to derare in the 30s and stop at ambient of 40. They wrre dedigned for europesn summers.

Coal can be flexible as it use to be beforr parasitic intermittent generation came on the seen. If you had enough plants they all didnt have to move much to make a large change on the grid

NEW Coal fired Power stations not only Pollute, they cost too much and are not flexible. Lots of people die Mining coal. My Grandfather was one of them. Black lung cases still occur and dust goes for Kilometres from Open Cut mines. Subsidence from old mines affects a lot of towns in Australia.. Pollution of rivers, like the MacArthur in the NT is of great concern. We NEED mining BUT clean up your game afterwards..Today the concept of BASELINE Power is used to confuse. Todey, Peak demand often relates to Airconditioner usage in the afternoon in Private residences. Not Heavy Industry. Nev

His niece. Mary Trump, is a qualified psychologist who doesn't hold back on Trumps unsuitability for the Job. She is in a position to KNOW. Nev

That's exactly the point. Fossil fuel supporters always bring up the cost of transitioning to renewable as a reason not to do it. Strangely, they never mention the cost of not doing it

By that time the British were well established. It was a different place than it was in 1788. Wool was a major export and the several localities were pretty close to self-sufficiency. One of my Irish ancestors came as a convict about 1834 and was assigned to a property in the Upper Hunter District. After he had served his sentence he made his way back to Sydney and went into business and beginning a family that did alright for itself. Since a lot of convicts were transported for what we would now consider trivial offences, once they completed their sentences they went on to make good lives for themselves. However, talking about what happened post-1800 is a red herring to the original point of the topic, which is the discovery of the true reason for the establishment of a presence here.

Our discussion around climate change has centred on power generation and ICE cars v EVs. But, it is a muilt-pronged approach required. As the rest of the world clears its heat sink, China is building its up: https://www.livescience.com/planet-earth/plants/trees-in-chinas-great-green-wall-appear-to-grow-faster-than-natural-forests-study-finds Where fossil or nuclear makes sense, it should be used. The reality with today's technology, there are fewer and fewer places it makes sense. And should the political shift to drive a shift to local storage and distribution, the use of rapidly outdating technologies will make even less sense. We talk about the economics of doing it, but we rarely talk about the economics of not doing it. And economics is man made, anyway... the real cost (ie. outcomes) of not doing will lead to socio-economic costs far beyond the pure economic cost of doing it.

Trump is a Malignant Narcissist. Here is an AI overview A malignant narcissist is a severe, highly toxic personality type that combines standard narcissistic traits with aggression, antisocial behavior, and sadism. Unlike typical narcissists, they actively derive pleasure from humiliating and hurting others to assert dominance and control. [1, 2] Core Traits & Behaviors While the term isn't an official clinical diagnosis, psychologists often use it to describe the most dangerous end of the narcissistic spectrum. Key features include: [1, 2] Sadism: They experience joy and empowerment when causing emotional or physical pain to others. Paranoia: They frequently view others as adversaries and may become deeply suspicious or defensive. Antisocial Behavior: A blatant disregard for rules, social norms, and the rights of others. Profound Lack of Empathy: They are entirely indifferent to the suffering of those around them and lack genuine remorse. [1, 2, 3, 4]

Yes,I agree,, It was a contextual comment and I was being a little lazy - on a train with a phone and fat fingers.

By the way, China's emissions have flat-lined for the last 21 months and may actually be falling slightly, although it is a bit early to celebrate. https://www.carbonbrief.org/analysis-chinas-co2-emissions-have-now-been-flat-or-falling-for-21-months/

Just who is doing better with renewables than CHINA ?The BIG news here is HOW the USA has got it wrong, and Smart, Knowledgeable people there KNOW it. but Trump doesn't WANT to know it. Nev

I always fact check everything anyone writes and I hope people will fact check what I post. Your figures are correct but with some caveats. In the following, I have omitted the calculations that validate your figres because as I say, they are correct. I am happy to provide links. What is potentially misleading? The statistics themselves are not wrong, but they can be misleading if they're presented without context. 1. China is much larger than it was in 1980 Since 1980: GDP has grown by roughly 50–60× (in current US dollars). Industrial output has exploded. Electricity demand has increased enormously. Hundreds of millions of people have moved into cities. An eight-fold increase in coal use is partly a reflection of China's enormous economic expansion. 2. Coal is growing, but so are renewables One of the unusual features of China's energy system is that both statements are true: China consumes more coal than ever. China is also installing renewable energy faster than the rest of the world combined. In 2024 alone China added approximately: 277 GW of solar 79 GW of wind bringing total new wind and solar additions to 356 GW in a single year. Non-fossil sources accounted for 56% of installed generating capacity, although fossil fuels still produced about 63% of electricity generation because coal plants are used more consistently. 3. Coal consumption isn't the same as coal-fired electricity Coal in China is used for: electricity generation steel production cement chemicals industrial heat Someone using these figures to argue that "China is building huge numbers of coal power stations" is oversimplifying. The statistics refer to total coal consumption, not just coal burned for electricity. 4. Coal's share of China's energy is slowly falling Even though the absolute amount of coal keeps increasing, coal is gradually making up a smaller share of China's total energy mix because renewables, nuclear, and natural gas are growing even faster. Overall assessment I'd rate the statement as: ✅ The numerical data are accurate (assuming the EIA dataset is the source). ✅ The 4% increase is correct. ✅ The eight-fold increase since 1980 is correct. ⚠️ It omits important context, namely that China is simultaneously undergoing the world's largest expansion of renewable energy while still increasing coal use to meet rapidly growing electricity and industrial demand.

The coal consumption in China in 2024 reached 4,947,281,929 metric tonnes, which is 4% more than in 2023, when consumption volume was 4,756,959,903 tonnes. It has been growing in this country for already 8 years in a row. According to the EIA (U.S. Energy Information Administration) data, since 1980, the annual consumption volume of coal has increased by 8.03 times. The minimum of China was recorded in 1980, with a value of 615,814,652 tonnes. The maximum coal consumption was in 2024, when it reached 4,947,281,929 tonnes.

Can we call you "Spud"?. Nev

My Irish Great Great Great Grandfather probably knew all about that, in the 1830s. He was transported to the Great Southern Land and slaved till he was made a free man in 1850. He proceeded to the Parramatta Female Factory to choose a partner, then acquired some land in Cooma NSW. The rest is history. Offspring are everywhere on the East Coast and inland. A few became famous ... even me, I discovered the Feast and Famine Variable.

Seems entirely reasonable. The Dutch weren’t interested in Australia but the French were.
