- Опубліковано 27 вер 2024
- Pylons are ugly and nobody likes them! Filling up our countryside with thousands more of them to facilitate a massive electricity grid expansion is proving to be a very tricky challenge with lots of local opposition. But what if you could build your electricity grid out at sea and just bring cables to shore where they’re needed?

The grid needs to be constructed, owned and operated by the government on behalf of all the people of the UK. Asking competitors to sort it out is like asking turkeys to vote for Christmas.
Not really. I work in the UK oil industry, and pipelines and infrastructure back to shore has routinely been shared for some time. Even in places where metering was terrible, agreements were made in proportional sharing. In industries like these, there are so many crossovers between staff, service companies, companies themselves engaging in joint ventures for capital etc that it's easy to come to agreement. I'd have thought wind would be even easier, as a turbine's output to its connection point would be fairly easily to calculate with a degree of accuracy. There's usually a cut to the pipeline (cable in this case) owner, but energy provision has - generally speaking - such a predicatable return on investment, that cooperation is much easier than non-cooperation.
@@ricos1497 Fair enough. Good to know. ;o)
What's worth mentioning is the excessive differences between Scotland providing large sums of the UK's generation and England containing the majority of demand centres. All offshore cables to be built East of Scotland down to England are to alleviate the issues with the constrained and near-bust B6 boundary overhead lines. I'm currently involved in proposing and designing new overhead line routes between Scotland and England, the amount of infrastructure to be established in the next few years will be some of the largest projects the UK has seen in years!
Sounds like an exciting project. Good luck.
Are people such as yourself and the industry in general in the UK aware of new cable technologies that typically use a carbon fiber central core to give strength rather than steel. This reduces weight and increases the amount of conducting material. The idea is not to simply reduce cost of new transmission lines but to restring exising overhead lines potentially doubling or even tripling their capacity. So much easier and cheaper than new lines?
@@petewright4640 I believe that steel/aluminium core still remains the standard due to supply chains etc but you're right that reconductoring is definitely the preferred way to go. Hopefully carbon fibre cores will appear soon and the saving in weight will allow for an increased conductor diameter.
Britain is composed of one represented Country - Scotland two represented Principalities Wales and N.Ireland and one confused mishmash of unrepresented regions districts and areas some of us still call England!
Thanks John
I enjoy your sarcastic humour. I also like the nice, darker, soothing living-room-wall colour.
Tidal power on the Menai Strait would be a useful strawman test on the greater implementation of inner tidal lagoons solutions.
We really do need to start using our collective consciousness when it comes to simple solutions for seemingly complex problems with green electricity provisions.
Like the gravitional system used in the Highlands of Scotland. Actual intelligence is always preferable to algorithmic design. As it includes the foulibles of the human spirit, IMHO.
#classaseverdave🎉
I didn't notice the paint as I was mesmerized by your sparkling oratory!!! Keep up the great content as I tune into you each Sunday.
The new color is a very good choice. Blue/orange contrast looks good, and you stand out better from the background. Good one!
You're right, he does appear to be much more shiney.
Love the humour in the teeth of this oncoming situation.
It helps a lot of the power grid is owned by the people, your government! If your politicians say they are going to sell your hardware tell them NO! I still own my power and water infrastructure through my state government. That is why we only loose power if a tree falls through the wires in a storm. We did loose the water once for about a hour as when they were working on the pipes in our street a stopcock broke. It was very old and they didn't have a spare in the truck because they don't usually break. Got to love being able to vote out a government that wants to sell the people's stuff to their mates.
Great sarcastic wit! Perfect finish...what could go wrong 😂
I love your sarcasms.
Very well placed!
I think Dave spent his entire weekly quota of snark on this video :D
He's like an ASMR Jasper Carrott
Tx for another great energy video topic. It seems getting electrons from point A to point Z is very complicated & complex indeed...
It would be helpful if we could convert existing power stations to renewable energy sources to take advantage of existing infrastructure. I have seen another suggestion that any new transmission & distribution infrastructure should be located along existing transport routes to avoid having to lease land from private owners etc. I'm more of a fan of interconnected distributed mini grids - especially in cities - so that energy is generated as close to consumers as possible. The great advantage of offshore wind though, is that it is less intermittent and is less obtrusive than onshore wind... it's complicated
I like the newly painted room. Great content!
oh yeah the environment loves that
@@President_NotSure lmfao
@@President_NotSure I'm sure it's No-VOC, so yeah, the environment DOES love that.
Not quite the burn you two kids thought you were doing.
Thanks Lawrence. Much appreciated :-)
I worked for a county council in support of the boreas and vanguard windfarms. The government collapsed the projects pretty roundly, killing off a further 2 and 3 GW of installation. I don't think the offshore ringmain is likely to work, not least because a lot of the issues they purport to avoid don't get avoided forever . Sooner or later, they have to come onto the land via primarily rural and conservative constituencies who also have the power to collapse projects by objecting to the installations. Sizewell is a good example of this - if the new nuclear powerplant is putting up a 3m high sea wall, its time to read between the lines as to what that means for your flat, coastal village.
From the referred report : The recommended Holistic Network Design
The result of the HND process is a design that: • Connects all 18 in scope offshore wind farms (with a total
capacity of 23 GW) to the onshore network.
• Includes regions of strong coordination, and regions where
radial connections are favourable.
• Has 15 landing points to shore.
This seems to indicate there will be a limited number of entrances for the offshore electrons. No doubt these will become nexus points for conflict around the world in the future with laser air defence batteries given the daft nature of some humans?
i grew up near Tilbury & the sky is full of wires, both the ones from the (now flattened) power station & the ones crossing the Thames & fanning out in all directions from the shore. The 330KV lines are fun though, humming & crackling in damp weather.
Great introduction to the proposed new connections for future wind farms.
Just love how optimistic you’re Dave, I’m guessing when you quote WT Wind Farm GW’s that’s that’s the combined output of rating plates not what they actually produce. If in the fullness of time we managed to produce enough alternative energy to power just current needs, that would still only represent 20% of the energy we use, which seems to be ignored. Jevon’s paradox will be playing out nicely, for just when you think electricity savings like replacing LED’s with Laser Diodes, along will come data centres wiping any savings, and plus some. As I travel around be it on land or sea I see great swathes of PVP’s and WT’s. If my great grandchildren coming up to 2 yrs old live to 80 they’ll see at lest 3 renewals of PVP’s and WT’s that’s if there’s enough energy to recycle them (and that’s another story, pollution), let alone manufacture replacements.They’ll also see 2050/60 and the oxymoron of Net Zero, and if it hadn’t already happened before 2050, then between 2050 and 2100 they’ll have seen, if not involved in fighting to maintain access to, well then the depletion of Oil and Natural, Gas, but also the rise of Coal to fill the energy gap, and be practising “The Great Simplification” but still well on the way to way to extinction. I really fear for what my great grandchildren, or a baby born today, will have to face in the future. And of course all of this rests on our not extinguishing ourselves in a Nuclear winter🤔
Happy everytime a new of "Just have a think" episode is released. And there he is. Thank you.
What's amazing is that National Grid and the government didn't see the need for massive expansion coming. Gaining a grid connection is now a major delay for maney renewable energy projects.
In the Netherlands also terrible: the whole grid is congested and it''ll take forever and all the money to upgrade. Companies can't get new grid connections or expand capacity, green energy is stalling and housing projects are in trouble. It is all staff shortage, nitrogen crisis, supply crisis etc.
No idea how this was a surprise or we even managed before.
I love this channel but I’ve ‘JUST HAD A THINK’ and remembered that the generators in wind turbines do not transfer electrons through the wires as Dave described but rather it’s electrical ENERGY that is transferred - NOT electrons - indeed for AC generation the electrons don’t actually flow anywhere, they just vibrate.
Maybe I’m splitting hairs and not the key point of this excellent video but I’ve heard Dave say this several times before.
Paint job looks great!
Thank you :-)
Loving the paint job and the content 👍🏻

The wall looks great!!!
Thanks for the excellent content...as usual.
Thanks Peter. Glad you enjoyed it :-)
All we need is a stiff breeze ! Thanks , I hope things keep moving !!
Actually just a gentle breeze & that 200 metres above what you notice. Many designs start up in 2mph winds & if you've got a weather vane in your garden & a windmill in view it's perhaps surprising how often the strength & direction of the 2 are different.
Break wind…? 😂
@@alanhat5252 Thanks, I understand. I met a snail in the grass, and said, "quite windy today". The snail : "what are you talking about"
Love the sarcasm! 👍
You have i informed me and made me chuckle. Great video mate. All the best.
The sarcasm goes well with the british accent lmao great stuff 👍
I am interested in why the UK has so much offshore wind compared with other countries. Pioneers in the technology? Now economies of scale. High but not too high average wind speeds? Relatively calm water enough of the time? Lots of shallow water around the coasts allowing fixed rather than floating towers. Accessible shorelines for bringing cables ashore etc. And ports for servicing. The UK is perhaps well-blessed with those qualities.
Question: How does all that offshore infrastructure affect fishing? Trawling and undersea cables are not a good mix.
I'd be interested to see just how offshore electrical connections are made. I suspect that avoiding offshore connections/switching is one (the most important?) way to minimise expossure to salt water.
I think the other issue is avoiding moving parts (floating towers, cables that must move with the floating tower) under water because of the high maintenance costs involved. Hence fixed towers better than floating ones. Hence look for shallow water.
DC advantages: the available current and voltage capacities are used all the time rather than use fluctuating. And better performance under water particulalry where large cables are required.
Excellent content as always. This is one of my favorite channels. But you did seem a tad feistier than usual, Dave (e.g., "And I can't think of a single thing that would possibly go wrong with that"). Not that I'm attributing this to the new paint per se -- could have been the time hosting seminars in London -- but I do hope those blue areas are well ventilated.
I love the Monty Python style riffing bit. 🤣
Love the paint job.

The problem I keep seeing with big solar and wind farms is that consumers don't seem to benefit in lower prices, and I know they say it's because of the cost of upfront investment, but something has to give at some point if they really want the public to be onboard with all this.
Personally, I'm more of a fan of generating our own energy, on-site as needed, and as the tech gets better and cheaper, it's becoming a lot more viable, and at least this way, you cut out the middle men and start to save on lower energy cost, and probably longer term, almost free energy.
The key to that is that a buffer is needed with energy storage, and that is where the problem is for now, battery tech is too expensive and the amount you can get is still too small, but eventually as tech keeps improving, I suspect a lot more of us will generate our own energy because it will work out cheaper, whiles giving us full control in lowering our bill, which I get a sense that it doesn't seem to matter how much big renewable projects that go online, our bills never go down and you can't help but feel they are profiting on that.
There's another factor, maintaining the grid network is really expensive, I heard somewhere that it accounts for around 40% of the entire energy cost, if so, then there are some major advantages in renewable on-site or gridless in the long run, cut out the middle men, no need to maintain a grid and so on.
Clearly, this isn't going to happen any time soon, but with the advancement of tech, it's likely going to be more viable for a lot of us.
It's just a shame that we can't have a mix of solar and win at a small scale, because that would complement each other really well, but every time I see wing turbines in urban areas, they don't work that well, but a lot of new ideas are coming around, so who knows, that might change, if it does and we can have both, that would reduce the need for as many batteries, as the energy generating will be more consistent, it will also allow us to generate a lot more energy at all hours and all year round.
So anyway, I'm hopeful about the renewable future, but personally, I think as tech advances, more of us will want to produce as much if not all our own energy needs on sites to cut out the middle men and actually get real savings and not just the promise of savings they keep telling us about.
How about windmills that are basically enormous bicycle pumps, with high pressure air hoses on the ocean bottom, which could be buried onshore to a station where an air motor (like a quiet triple expansion steam engine?) would spin a generator. No electrical dangers, and any leaks would be easy to find. Multiple mills could be ganged together for increased power. Im sure air hose would be orders of magnitude cheaper than the underwater wire currently used. Electrical generating windmills have hugely expensive and complicated systems that require mechanisms to keep them spinning electrically in phase as wind speeds change. That wouldn't be an issue for an air pump, as the faster it spins the more air is pumped. Excess air could be stored under pressure in bladders on the ocean bottom. As an added incentive, design a system to chemically collect carbon dioxide, from the compressed air supply for accurately measured carbon credits, and possibly, some rare gases could be collected as well.
It’s blue Dave !!
More wires, baby. More wires!
Collective Action Makes a Difference
Offshore windmills have a relatively short service life due brutal conditions. The decommissioning costs will be horrendous
You're not missing anything, it will be bloody expensive. The other problems are coordinating it, choosing where to build, getting the green light for anticipatory investment, choosing who will be the organisation who builds it (the offshore system operator), etc.
On top of that the risk of stranded assets is huge because of the problems with the CfD.
The UK hasn't even got close to getting it right first time, and the £5bn saving is based on amazingly optimistic forecasts.
The simpler, more efficient and cost effective, way for it to be dealt with would be to specify the additional equipment required on the offshore substations to connect them at a later date.
Low frequency AC is thought to be most efficient by a German professor after they'd already gone down the difficult HVDC route.
Sea transmission lines are not only more expensive to install, they are also much more expensive to maintain. All for the aesthetic reason of not having to look at on shore power transmission cables (most of which exist away from population centers). I understand the NIMBY mindset, but I certainly wouldn't say this is a "future proofing" option because we know those in charge will eventually get tired of fully funding the expensive maintenance of underwater cables, and the infrastructure reliability will suffer as a result.
It's all about synergies.
Combining the offshore grid with a large scale build out of ocean habitat would restore the oceans and convert unlimited amounts if CO2 into food. (And to the floor via detrius)
It's very expensive but done right can pay for itself.
Done right you can even combine it with offshore desalination and pipes to bring the water to shore.
Offshore desal can use deep water pressure that runs for the cost of an extraction pump because you don't have to pressurize water and then release half of it as brine. Put the filter on a tank. Sink it and pump out fresh water. Cold enough for AC if you want to go crazy.
Did i missed something or did you have sarcastic week in the UK at the moment?
Every week is sarcastic week here in Blighty mate ;-)
Sarcasm turned up to 11 this week, I reckon!
Another great episode!
Thank you :-)
Enjoy all your videos.
As always, insightful and interesting video. Maybe a topic for the future could be about why we don't build grid scale battery farms (plus other storage like radox flow?) where wind energy comes on shore which would be able to balance grid and pretty much pay for itself as we wouldn't need to pay wind farms to stop producing. Added to having a more local/decentralised system via home solar and battery storage, wouldn't this be best for our future and reduce prices?
The only problem with the new paint is that your shirt matched it so well! Think contrasting colors or bright lighting on you _or_ the wall (not both).
Yeah, the top this week was a mistake. All part of the learning curve I guess :-)
I really enjoy your videos, thank you for your quality content. Could you please turn the volume up a little bit on your videos, I work in a data center and I have a hard time listening to some of your videos with computer fans whirling in the background
Perhaps another round of nationalisation is called for.
The best part of offshore wind turbines mean we get to give the royal family loads more money, they own the coast and we have to lease it off them. I get a warm fuzzy feeling inside knowing the ultra rich get more money for not doing any work.
Thanks for another great video! Britain seems to be in an unusual position when it comes to global warming and the energy transition. On one hand your Conservative politicians sometimes say rather disturbing things, and support silly ideas like converting everyone's water heaters to hydrogen. But on the other hand Britain is actually doing a lot to transition to renewable energy. You're building real renewable infrastructure with all those wind farms, it's not just talk at climate conferences. So keep on doing what you're doing, I guess. You really are a wind power pioneer, no matter what the politicians say.
Yet in the UK we pay massively more than the rest of Europe for there electricity. Greed. I lost my job last year and my electric bills are crippling. Saving the world, reducing the emissions, being smug sounds great but I'll be living in the streets, crippled by the high costs.
I'm sorry to hear that, mrpugster. Hopefully things will turn around soon for you.
Considering the scare about underwater gas pipelines and internet cables getting cut by the adversary of the week maybe not put the national grid there too.
thanks rodney
I see what you did there. Very good. :-)
Your video's are always terrific, thanks for sharing! If the mass production of Graphene is ever perfected, our existing electrical grid will become obsolete overnight! Graphene's characteristics is very similar to a true "superconductor!" These Graphene cables could be buried, who needs those ugly and dangerous existing high voltage systems? Another bonus no AC-DC conversion as needed with a true super conductor.
Australia's 4,000km southern coastline borders the circum polar winds that blow clockwise 24/7 around the Antarctic and across the southern ocean.
Australia has an offshore wind potential of several PW (>1,000,000,000,000 kW), about 100x the national demand.
Australia currently has installed OSW capacity of 0W.
Not to mention 80% of the population live in the coastal zone. We're a joke.
I like this idea a lot. Wish my cointry's geography could allow for such infrastructure
Winds. I took a quick look for an hour but it needs a well-paid professional because the Sun keeps forcing the wind to happen due to it heats Earth unevenly (Tropics face the Sun more directly than Polar regions and that's what causes steering winds). I did calculate in my head that wind kinetic energy matches 7 days of all human energy use (if my memory from 3 years back is correct) but since the Sun will fight any attempt to stop the steering winds simply by blocking them (as opposed to heating at 60-90N which I hypothesize might be slowing the Ferrell Cell) and since the Sun is massive powerful I can't see any feasible mechanical effort to slow the steering winds being able to slow them much due to it's directly fighting the source of ~all energy on Earth. Geothermal & nuclear fission are 0.035% and 0.015% of all energy on Earth, not much of a portion.
Well said
I notice from that map that Devon & Cornwall are miles away from any renewables. We are always forgotten, until you all want to come down here on your hols.
I guess the best weather in the UK means the least wind? You should be the best place in the UK for solar, though.
@@philallen7626 Not really, we always get the worst of the Atlantic weather as it sweeps into the UK, but we do get good wind earlier today 45% of our energy was wind and 37% solar today. But gas was the rest.
Solar was a surprise as it's not been to good for solar lately
Rather than trying to grow the grid so quickly and building unsightly features, the government should pay for every house to have a 1kw solar panel system. That way we massively reduce our reliance on a bigger grid and still meet our targets. The systems can then be upgraded as we reach each target. Unfortunately, the whole.thing is about people making money and getting back handers so a true change will never happen quickly or in the best interests of the people
I’m waiting to hear if your eye has fallen on the “Boring” company…
Those concerns about transmission towers look to have a pretty interesting solution on its way…with added benefits.
i dont understand why the underwater tidal farms arent a critical portion of the grid esp since such power sources are not subject to intermittency except in the case of maintenance
According to Google, the average cost of a large offshore wind generator is 20M. Apparently, the average home to go off grid would be around $30K with little maintenance, whereas, the average maintenance cost for a wind generator is around $45K per year. IMO, to solve most of the problems that you've pointed out could be solved by requiring, and using the $20M (plus the cost of many more wind generators) to subsidize every home and/or land owner to have their own solar and battery system, with little to no maintenance cost per year. At the very least, have mini-grids in every neighborhood. Little to no infrastructure needed. Of course, the people in charge want the big bucks for themselves while not allowing electrical independence for the average citizen, as proven by what happened to Nikola Tesla. Heavy sigh...
1:32 the thing you’re missing is UK nimbyism.
As the benefits of a complete and nationalised energy system are now blindingly obvious, what’s holding our political leaders back? (Don’t pretend it’s the cost, with such huge savings opportunities.) Could it possibly be personal greed? Or just fear of being radically in support of ordinary citizens?
Great video as usual 👌
Glad you enjoyed
I think you're being a bit too generous to the onshore peeps here. I do admittedly also think their detractors are too harsh! They're not wrong that there are downsides to the land based option but they seem to very much be arguing that a mild inconvenience to them shoukd be valued as a cost of £infinity, regardless of anything else. It's that aspect of it that seems to drive everything and it is that binary, winner takes all, thing that makes so many green energy projects unnecessarily difficult. It would be very helpful if we had systems in place that more reasonably compensated losses and inconvenience incurred by people, such that it sometimes becomes the better buisness choice to take an alternative route, and so companies are incentivised to do that, and sometimes it's still better to build the green thing and get it working but instead of valuing residents at zero in that scenario they then recieve an appropriate cut of the gains for the negative consequences they experience.
I like the new color better.
Thank you :-)
logically, this is where we need to focus our efforts for the greenest energy possible.
Ocean energy is provided FREE every day, by the gravitational effects of the moon and sun.
Our task is to find a way to tap in to that energy of tides and currents.
Wind and Solar is NOT the way.
Germany is at present something like the same but that example is in only one Country. Britain is composed of one represented Country - Scotland two represented Principalities Wales and N.Ireland and one confused mishmash of unrepresented regions districts and areas some of us still call England!
This is very interesting but have we considered nukes?
Grimsby is a fifty meter pile.
Sir Francis Drake sailing back to England and seeing all these ocean based wind farms through his pirate telescope would have said ..
I wonder how much energy we can take out of global coastal wind systems before we start affecting local weather patterns? Would our maximum potential demand just be a drop in an ocean of available energy, or would we need to limit how much we would take out? Are there some unintended consequences we should be wary of?
Interesting fact I heard from some other environmentally aware youtuber is that climate change is also causing poles to warm up much quicker than equator, which means less difference in temperature hence less wind.
There will always be wind as long as the earth is turning.
For sure northern polar is warming 3.8x as fast as average. My understanding is that southern polar is warming less than average but there's big disagreement between instrumental bunch & proxy bunch. My opinion is southern polar is warming less because southern Polar Jet has strengthened & tightened instead of going Wonky. I think you are correct regarding 30N-60N and I even wonder whether that's part of why the ocean's warming more. I have thin tentative science on it though, ongoing hobby project.
Never do anthing in a high cost, low productivity environment (offshore) that can be done in low cost, high productivity environment (onshore).

So much load shed not enough batteries 😏
That's great but your numbers are a little bit off
Once you have more than two sublime and generating electricity on the same line you could only get and use less than 20% of the advertised output it's called ohm's law so the inherent problem with the meters are not designed to run backwards
Electricity is like water you must overcome the incoming voltage or pressure if you will to put anything in
Have you ever used a car battery charger it's kind of like that as the battery gets Fuller less power goes in but Watts stays the same
Isn't AC less "lossy". I'm pretty sure DC is super inefficient over long distances.
The West Coast of the USA is too seismically active for much off-shore anything, or on-shore nuclear for that matter. It sure is pretty, though.
Let's have a re-think about the UK's Carbon offset figures when knowing that In 2022, the UK imported a total of 7.52 million metric tons of wood pellets for energy production. This was down from a five-year high of 9.13 million tons in 2021. According to data from the UK government, the majority of wood pellet imports, approximately 60%, came from the US.Feb 5, 2024. Look for reports that whistle blowers point to North American healthy trees being cut down to make those pellets spinning UK electric Generators formally fuelled by coal, and that burning wood fuel pellets is dirtier than coal. Now let us all just have a re-think about how proud to be about correct UK carbon emissions to computate, then publish so proudly.
I often wonder if all wind farms should have a direct fed storage facility onsite to allow them to collect the most they can more often and then deliver a stable supply when the wind drops. Not all but enough to help is the idea.
Also I have very little trust in commercial companies in generation. Perhaps a VERY muscly regulator would help. Better still, if they can make a profit, shouldn't we be the owners.
i think it's a mistake to re invent the grid by re centralizing production instead of diversifying it.the only reason for high voltage AC is for reasons of transmission over long distances. home solar low voltage (12 v) D.C. storage coupled with neighborhood low voltage D.C. storage and solar / wind generation facilities might make more sense. funny how in a way, Edison may have had it right in the first place.
Collective action or a group of NIMBYS. Running the countries electricity grid through international waters, what could possibly go wrong 😀
Why offshore cables why not hydraulics and generate onshore demineralized water with inhibitors will be much cheaper than electric cables with pressure to operate the same as trailer brakes and the pumps can be housed in the base of the structures
Will the HVDC cable going down to Morocco for solar connect to this grid?
10:56 as if Florida is still a state
Nations should just take control of all electricity production and supply

Grid electricity is all grid costs and dirt cheap electricity.
But just the local grids cost $millions per km.
So off shore grid is $?????millions per km.
Then, the onshore grid has to be increased in size, $???millions per km.
Rooftop solar PV and EV big batteries have NO GRID COSTS.
Just my thoughts.
