While watching other people work on YouTube I saw something that makes a lot of sense to me - pipe-in-pipe flexible water feed which basically guarantees if an internal pipe starts leaking it will just drain into the external one and out. Ran a search here and found nothing - maybe used wrong terms. Is there any reason not to use it for anything running inside a wall? Or is it just not well known?

Nope, as I said, just going to play with wood. Watching videos of professionals is inspiring, a lot of fun. Want to try and replicate at least something, for example, cut my own rafters for the outbuilding I still can't get the drawings for.

Wow, well done! I have actually ordered a few lengths as a birthday present for myself to play with. But 9x2 was about £5.10/m including vat... so 40% more than what they offered you. And can't find OSB18mm cheaper than 30 at Wickes taking delivery into account. Need to finally try talking to jewsons then. Thanks!

Lies, damn lies, and statisticians. Insert a smiley of your preference.

And you are still not getting it 😞

@Dillsue Don't know what to say TBH I am afraid you have missed the line of conversation completely. I am well aware of how much RE and FF are providing nowadays, this is really not the point. Rhetorical questions, all that.

I have no idea what you want to say here. The current status doesn't matter, only the planned aim - no FF generation - does. How does gridwatch help??

@Mr Blobby I am sure you believe you wrote a great rebuttal of something I claimed. In reality you did nothing of sorts. Cheap shots at what "I may think" and references to DM only work in your head (and of course for those who support your views) yet they are nothing but cheap shots. The elephant in the room which you chose to completely ignore describing in great details how everything works is the percentage of the generation that needs to be covered by these peak providers. Would you care to disclose this? All these little diesel generators waiting to play their role - do they cover 50%? 20%? Please, enlighten me, can't wait. A hint: the relationship between baseload and peak is very roughly 1. Most of the peaks are expected, hell, they do occur daily (on working days) so historically peak providers knew that they would be selling a certain minimum number of hours a year. This makes sense as a business. If the system uses 50% of installed capacity the losses are predictable and manageable. Now take this nothing that our great wind generation capacity (only a little sarcasm here because it is indeed a significant gen - when it works) produces a few times a year, add all this nonscalable (any time soon) nuclear and completely nonscalable bio and of course zero nightly solar and tell me, how much will need to be generated by spare in this scenario? By diesels? By what exactly? These diesels - as I am positive you know full well - are only there to cover a tiny little extra if and when the need arises, the same way a hospital would have one ready. Do you have any choice but admit that close to a 100% of existing FF generation will have to be on standby just in case - unless the storage technology we all want (no sarcasm here) does become available? And if that is indeed the case then the cost of the unit produced will inevitably be way higher because it will only sell for maybe a couple of weeks a year rather than 5 days out of 7. And before I forget: your diesels won't work in 10 years as "Just stop oil" morons will get their wish because most good people don't want to condemn them or explain to their own children and grandchildren how dangerous this crap is. It's nice to support everything good against everything bad. Be careful what you wish for.

It's obvious BS and you know it. But will you admit it when IMF says otherwise? 🤣 Not hard to find at all "Just 8 percent of the 2020 subsidy reflects undercharging for supply costs (explicit subsidies) and 92 percent for undercharging for environmental costs and foregone consumption taxes (implicit subsidies)." I.e. Russia supplying Belarus or its own consumers at a reduced cost, SA/Bahrain/Venezuela etc. doing the same. None of them sponsors UK or EU. But I am sure we've been through this before. There are also central bankers claiming climate change is a major threat to the financial system. One has to have guts to call this out. One of them all. https://www.federalreserve.gov/newsevents/pressreleases/waller-statement-20221202.htm

Sorry, I am not sure what point you are making - is it about the past or the future. I asked whether somebody was subsidising our very reasonable energy prices for 20 years - say, until covid. I am aware of Belarus situation or rather was aware when I still cared. But as I am sure you know it is a tiny country in comparison to Russia. It is a relatively cheap way to buy influence. But Europe as a whole is too large to subsidise. Buying individual politicians and organising various "green" groups provides a much greater ROI.

While some keep insisting "everything works in theory" I can only recommend reading the energy transition plans in the most "advanced", woke, "green" places like California or New York. You will be amazed by the detailed information on how exactly the net zero is going to be achieved. A spoiler: there are no details, just vague references that "technologies" would become available. They might - never say never - but no sane person would take a plunge on such a flimsy basis.

Are you saying that before our energy prices were subsidised?? All these dictators of the world were helping us out until recently? You can't mean this surely? I am happy to pay the price, I am not happy to pay for the results of stupid and completely unsustainable policies.

They? What percentage of the generation was baseload and what was peak previously (the first number I saw showed 50% for Germany)? And what part of the year would peak plants produce? These are pretty basic questions, look into this and it will be clear that there is no free lunch. Either you use expensive plants with a relatively low marginal cost as the baseload or you build relatively cheap gas plants (a lot of them!) with high or potentially extremely high marginal cost, in any case you need to have a very high percentage of your full generation capacity on standby. And if you do want to use mainly gas in this role you need to have a reasonable gas storage, at least 2 weeks of consumption, but not only for the peak anymore - for your full capacity. I can't see how this won't make the cost of this generation relatively higher. You invest 100mln in a plant which you might be able to use for an hour a day 20 days a year (and sometimes 24 hrs a day 14 days a year). Hmm...

Do you mean by paying 50p per kWth? 🙂 Or actually much more - I did link to the spot prices reaching £1.5 IIRC both here and in mainland Europe. I can only suggest to think a little as a potential owner or an investor of such a business.

Great And how do you propose to finance a business that must be on standby 24/7/365 but sell nothing whenever someone else cheerfully says "I can generate now"? I.e. all buildings, machinery, infrastructure, personnel, contracts for all required inputs and the actual stored raw materials must be in place - but cannot function. Would it surprise you if the resulting cost of the output were say twice the normal level (normal - based on competition with no pressure to cut emissions)? Three times? Is it an acceptable price for the pleasure of knowing the rest is "green"? And by the way, the higher is the share of unreliable generation, the higher is the multiplier - for obvious reasons.

hmm is this "theory" that you take so hard? Have I actually used insults (plural)? Or do you take sarcasm ("clowns like me... smartest people like you") badly? I am slightly disappointed. And here you go again trying to avoid accepting the obvious Just to make sure we are talking about the same thing https://www.nationalgrid.com/stories/energy-explained/how-much-uks-energy-renewable#:~:text=What renewables are used to,organic materials to generate electricity. "Today, there are four main renewable energy sources used to power the UK: wind, solar, hydroelectric and bioenergy. They harness the natural power of the sun, our weather, our waterways and tides, and organic materials to generate electricity." Your point was: we always have RE, we just need to scale it. It could have been true if we could scale hydro massively - but we here in the UK and ultimately the world as a whole can't do it. It may become true in some remote future if tidal gets massive - something tells me that if it's not happened yet there are pitfalls. As hydro and tidal and bioenergy (don't they include US pellets into this??) are not scalable enough, they will not provide 50% let alone 99% of our needs if the output of your favourite 2 is down. So as things stand the only sources you can claim are scalable (and in fact you repeatedly claimed we need to scale, the link can be provided upon request) are wind and solar. And now - good luck proving these two may indeed get us through a winter after all your scaling effort from the low of 0.035GW.

@SteamyTea FCOL @jack told you exactly the same thing this summer and you pretended that nothing must be equal to zero and not a very low number exactly the same way. Theory, theory, theory. I rest my case. Didn't plan to persuade you. I just want normal people to understand what they are getting into when they support politicians talking about net zero and similar BS, when they say they "understand the feelings" of eco-terrorists etc. Sleep-walking into a disaster.

Your original question : >>> Can you show me the times when there was no RE generation at all. >>>Then it is just a matter of scaling. "Can you show me something you didn't claim existed". I showed you how low it got - with all the installed capacity. Yes, the number is specifically for wind but it really changes nothing in the argument: a lull can occur at night when solar is not around either (actually, I did not check when it happened, it really does not matter). I do hope you are not planning on splitting hairs including biomass or other non-scalable options.

I have almost missed the most obvious : >>>So Biden has cut production has he How did you manage to read my post and decide that I claimed that Biden actually cut production? I mean, seriously, have you really read the quoted sarcastic text this way??? It was actually referring to the multiple statements made by this clown - see below. It is hilarious (and sad) when people take the first link off the Internet that seems to confirm their POV. Now, if you look at your own second graph you will notice the strength of the "rebound". What could possibly explain this? To make it easier here are a few links (note that I intentionally exclude any possible "right-wing" sites) https://www.cnbc.com/2021/01/27/biden-suspends-oil-and-gas-drilling-in-series-of.html https://www.politico.com/news/2022/03/15/drilling-permits-spiked-then-plunged-under-biden-00016814 https://www.washingtontimes.com/news/2022/nov/7/republicans-rip-bidens-energy-agenda-after-he-vows/ In case you don't have access to the last one from Google "7 Nov 2022 Mr. Biden pledged "no more drilling" at a Sunday rally for New York Gov. Kathy Hochul, drawing headlines just two days after he said he would shut down coal plants "all across America" and ... " Now, imagine that you are an investor considering whether US oil is a good place for your money. What do you think? Another example of "who do you believe, me or your lying eyes?"

"Who do you believe, me or your lying eyes?" 🤣 Theory, theory, theory. And at our expense I must stress.

There is a website for clowns like me which is hidden from the smartest people like you https://gridwatch.co.uk/WIND Now that you finally have this link, would you be so kind to locate the numbers called "minimum" under each graph? This month? This year? Last year? Can you possibly divide the max by the min and share your findings? Or is it too much to ask? As a hint - the min (last year) was 0.035GW. Scale this all you like, but can I ask you to pay for it yourself please? I will happily take my FF for now. May be you don't believe that the market price rise (albeit temporary) shows you something useful. "German day-ahead power prices rose 33% to €434 (£373) a megawatt-hour, the highest since 13 September, while the French contract rose 40% to €465 a megawatt-hour, Bloomberg reported." Theory, theory, theory.

Daft. Right. You can't make the same point - it is not supported by the facts. Europe has been building RE like crazy and trying specifically to lower its reliance on FF - and ended up in shit. Same for California BTW. Can you deduce anything from this? Would such a deduction really support your point? Or is it like Socialism - "it was never actually tried properly"? Close - but no cigar. 1. If you don't produce anything by yourself and rely mainly on shady regimes then yes, sooner or later you will be in trouble (1970s) 2. If a reasonable amount of what you need is produced by normal countries the chances of the squeeze fall dramatically: see as an example the price of oil this year which didn't go anywhere near the levels feared. Why? Many reasons, but the ability of the US to supply (thanks to Trump and Texas first of all and despite Biden's best efforts) is one of them. POTUS asking Saudis to increase production instead of helping to ramp up his own - the definition of stupidity. "We will be very green, we will cut our production, we will force our banks to stop financing FF - but can you, appalling prince, just pump more so that our prices aren't too high?" Do you not find this disgusting? So if you really want to shoot yourself in the foot - go ahead and support further reductions in financing for the new FF "to lower the dependency". Please don't be surprised 5-10 years down the line. Again, you have been warned.

Of course! Only you do! Good luck living in theory.

Sarcasm not detected? 🙂

@Carrerahill @ProDave It was @epsilonGreedy who warned of these problems https://app.electricitymaps.com/zone/GB?lang=en Select the 30-day period and enjoy the veiw of prices. https://www.theguardian.com/uk-news/2022/dec/11/uk-power-prices-hit-record-high-amid-cold-snap-and-lack-of-wind-power The wind doesn't blow all the time and the Sun doesn't shine - impossible to predict. If only we could build 50 times the existing renewable capacity... For those who still believe we should build as much RE as possible ASAP - "One day I'm going to live in theory because in theory everything goes perfectly" For everyone else: HSBC announced that they are not going to finance any new FF projects. There will be more of those - I did warn about this before. Greens are Putin's best friends.
