The energy crisis is complicated, almost certainly more complicated than you imagine. So be wary of seductive catch-all explanations: it’s Russia’s fault! It’s climate change policy’s fault! It’s all because the wind isn’t blowing! The reality is there’s a lot going on at once.🧵
A lot of people are convinced this is all because Russia has restricted flows of gas. And flows coming from the Yamal pipeline certainly dropped sharply in Aug. BUT actually Russian flows are UP vs start of 2021 (albeit lower than pre-pandemic). Good @WoodMackenzie chart:
A far bigger part of the explanation for rising gas prices is those two red arrows on the left of the chart. We’re not getting as much LNG tanker deliveries as usual and domestic gas fields aren’t producing as much as usual. These seem like bigger deals than Russian supply.
Another claim doing the rounds on Twitter is that the UK is uniquely affected by this crisis, and that it’s all down to Brexit. They seem to derive from graphics like this one, widely shared here. LOOK: UK prices are MULTIPLES higher than in Europe!
The problem with snapshots like that 👆is they are just that: snapshots. For a period last week UK prices were indeed WAY higher than most of Europe. But that wasn’t due to Brexit. It was because of the interconnector fire I wrote abt here: edmundconway.com/energy-and-inf…
It’s bit like taking this point on this chart (day ahead UK electricity price) and using that to compare UK with elsewhere. Which is what people have been doing; and then blaming Brexit. Both of which seem wrong. Prices certainly higher now. But much, much lower than that spike
HOWEVER, it’s also true that UK energy prices are stubbornly higher than in most EU countries. Gas and power prices are up everywhere, but the level in the UK seems highest. Why? For a few reasons…
This shows you where we get our power from in each autumn (well, each Q3) going back over a decade. You can see a few trends: look how coal has nearly disappeared. Nuclear is a bit thinner than before (ageing reactors; fewer reactors)
Now look at that wind slice. It was growing and growing (it provided more than a fifth of all our power in 2020). But in 2021 it suddenly shrank. And what took up the slack? Imports. Which helps explain why the interconnected fire freaked ppl out: we NEED power imports right now
Wind speeds have been REALLY weak this yr.
Look at this chart, a bit like some of those excess death charts you’ll prob be familiar with.
The whiteish range is where wind speeds tended to be each month over the past 20 years. The black line is this year. Look how low it is!
Another factor in the energy crisis is storage. The EU has less gas in storage now than usual.
But on top of that another issue is that the UK’s storage CAPACITY is really, really low in comparison with other EU nations, so we’re reliant on imports of gas as well as power
What does all this portend for the coming months? Are we really facing the prospect of a three day working week and blackouts? National Grid insists no. @WoodMackenzie says it can envisage one scenario (low wind, low gas availability) which would leave UK unable to fulfil demand.
In short, energy may make for a very nervy winter - as if there wasn’t enough to be nervous about. If the wind starts blowing again, that would really help. But hoping for a change in the weather doesn’t constitute an energy policy. And still somewhat unclear what UK policy is…
Here’s a short @skynews explainer I did on this last night. I should point out a mistake, which is that I denominated the gas price in £ rather than p. 🤦♂️ But the broad idea is not so much the price as the v dramatic shape of those lines…

🚨Latest UK population numbers just landed.
Two headlines:
- The UK natural population (eg domestic births minus deaths) is now FALLING - at the fastest rate in modern history.
- Yet OVERALL population is rising at the fastest rate since 1948 🤯
How? Lemme explain...
🧵
Nearly every year since records began a century and a bit ago, more people in the UK were born than died.
In the year to 2023, that changed.
664k births. 681k deaths.
The net drop of 16k is the biggest on record (also in % terms).
It's a watershed moment for UK demographics.
Yet the overall UK population rose.
& not by a little:
...at the fastest rate in 76 years! A near 1% increase.
That's a massive change in the number of people in the country.
How? You probably already know the reason...
🚨This is the story of how UK & EU goods are STILL going into Russia in vast quantities, despite sanctions.
Of how the economic war waged by the G7 is failing.
Of how I witnessed sanctions rules broken in plain sight.
But above all else it’s the story of a chart... 🧵
Here’s the chart in question. It shows you UK car exports to Russia.
And there’s a clear story here.
Look: when Russia invaded Ukraine, the UK (and for that matter most of the G7) imposed sanctions on Russia. So exports of cars to Russia stopped.
End of story, right?
Wrong, because now look at what happened to exports of UK cars to countries in the Caucasus and Central Asia.
At precisely the same moment as sanctions were imposed on Russia, exports of these cars to Russian neighbours suddenly ROSE.
🧵Here’s the extraordinary story of a Frenchman who came up with an invention that changed the world, before events took a twist.
It’s a rollercoaster story that just might help us solve one of the biggest challenges facing humanity.
Sounds far-fetched, I know, but read on…
The man in question was Nicolas Leblanc.
Born in 1742, he trained as a doctor but was always short of cash. He became the physician to Louis Philippe II, Duke of Orléans - a minor French royal. Like many enlightened intellectuals, his hobby was scientific experimentation.
And when he heard about a scientific competition, launched by the French Academy of Sciences and backed by none other than King Louis XVI, he jumped at the chance. The prize of 2,400 livres (quite a lot - a few years of earnings) would go to whoever could turn salt into soda ash

This is a thread about what I call the LEGO conundrum.
It begins when you ponder what a LEGO brick is actually made of...
Standard Lego bricks are made of something called Acrylonitrile Butadiene Styrene.
ABS is a tough thermoplastic you often find in the handles of scissors or the frames of hard carry-on baggage cases.
But Lego bricks are prob the most iconic application. en.wikipedia.org/wiki/Acrylonit…
It's worth saying btw not all Lego pieces are made out of ABS.
Baseplates are moulded from high impact polystyrene. Gearwheels are polyamide.
The small, flexible green pieces that look like plant stalks or flags are polyethylene, and so on and so on. lego.com/en-us/sustaina…

It might look like something from space, but some folks think lumps of rock like this could help us solve one of the biggest problems facing the planet.
Others fear they could trigger ecological catastrophe.
Presenting the weird, unsettling story of polymetallic nodules
These potato-sized mineral lumps form over millions of yrs on the ocean floor as metals accrete around organic fragments.
Up until 150 years ago no-one knew polymetallic nodules even existed. Today they're a very big deal.
So. Here are the 2 main things you need to know abt them
1. These nodules contain ASTOUNDING concentrations of certain metals - esp nickel, manganese, cobalt and copper. The grades of metals are multiples better than anything you can find on land (esp now we've mined out most of the easy stuff).

80 years ago today, newspapers in Europe carried news of the unexpected death of a very important man, in a hotel miles from the nearest city.
A man who, said some, was helping the Allies win the war.
But there was a twist to the tale. The man in question wasn't actually dead
That man was John Maynard Keynes. The 61 year old economist was at the Mount Washington Hotel in New Hampshire for what became known as the Bretton Woods conference. And the day earlier he had indeed collapsed, following a heart attack. It was a moment of high drama.
The conference had already overrun.
It was supposed to be done in two weeks and there was talk that the delegates would soon be kicked out of the hotel. This was, to put it lightly, a problem.
After all, in the absence of an agreement there was a chance of yet another world war
