Britain May Be Past Saving. Here's the Arithmetic.

Britain is a medium-sized island off the north-west coast of Europe whose inhabitants are chiefly notable for three things: an unshakeable belief that the weather is about to improve, an extraordinary talent for forming queues, and a political class that has spent the last thirty years carefully ensuring that nothing large can be built anywhere, by anyone, for any reason.

It is also, if you look at the numbers with the lights on, a country in the early stages of talking itself out of existence. Not dramatically. Nobody is storming anything. It is happening the way a stately home falls down: one damp patch, one cancelled repair and one strongly worded consultation at a time, until one morning the roof is in the drawing room and everyone agrees it was a great shame and that someone really ought to have done something.

The question worth asking is not whether Britain can be saved. It is whether anyone still in the building is even holding the right toolbox.

 

Money Is Just Energy Wearing a Suit

Start with the one piece of economics that almost nobody disputes, and almost no British government has acted upon. Prosperity is energy, transformed. Every major leap in human wealth has come from moving to a denser fuel: hay into horses, then wood, coal, oil, gas and uranium. You turn energy into work, work into goods, and goods into hospitals, schools, pensions and the occasional very expensive railway to Birmingham.

At the scale of the whole planet, the relationship between energy consumption and economic output is so tight it is essentially one for one. When the world uses more energy, it gets richer. When it uses less, it gets poorer. There is no hidden third option in which everyone uses less energy and gets richer, however many think tanks have gone looking for it. It's a bit like discovering that the secret to losing weight is to eat less, except that in this case the diet also involves closing your factories.

Britain, naturally, believes it has found the third option. Its territorial emissions have fallen by roughly half since 1990 while GDP grew, and this is presented, with some pride, as proof that you can decouple prosperity from energy. It is a lovely chart. It becomes somewhat less lovely when you notice what else happened in that period: the country closed most of its heavy industry and began importing the steel, chemicals, ceramics and manufactured goods instead. The emissions didn't vanish. They emigrated, taking the jobs with them, to countries with cheaper power and considerably less fastidious grids. This is not decarbonisation. It is a man proudly announcing that he has given up smoking, while paying his neighbour to smoke on his behalf.

Meanwhile Britain has achieved something genuinely world-class: some of the highest industrial electricity prices in the developed world, and by several measures the highest of all. If you want to build a data centre, an AI cluster, a steelworks or a chemical plant, the very first spreadsheet you open will politely suggest that you do it in almost any other country. Having spent a fair amount of time thinking about where compute should physically live, I can confirm that "small damp island, excellent tea, electricity priced like a controlled substance" does not appear near the top of anyone's shortlist.

 

The Two Kinds of Spending

British political debate about money runs on a single, very confused word: "spending". One side says the state spends far too much. The other says it spends far too little. Both are, infuriatingly, correct, because the word is being used to describe two entirely different activities that happen to involve the same currency.

Money spent building a reservoir, a grid connection, a nuclear plant or a railway is capital. It creates an asset that makes everything built on top of it cheaper and more productive for decades. Money spent on transfers is consumption. Some of it is essential and humane (a civilised country catches people who fall), but it doesn't compound. It is spent, and next year it must be spent again, rather like a gym membership that you actually have to keep paying for.

Consider water. Britain privatised its water industry in 1989, has added roughly ten million people since, and has built precisely no major new reservoirs in over thirty years. Kielder opened in 1982, Carsington in 1992, and then the nation appears to have concluded that it now had quite enough places to keep water, permanently, regardless of how many people might subsequently turn up wanting a drink. It is an island surrounded entirely by water, where it rains roughly every other day, which still manages to hold hosepipe bans. Future archaeologists will study this and assume it was some kind of religious observance.

On the other side of the ledger sits a benefits system with tapers so steep that, for some people, taking an entry-level job leaves them worse off than not taking it. If the effective marginal tax rate on your first hours of work approaches 100%, you haven't built a safety net. You've built a hammock with a lock on it. Add a large, growing and electorally formidable pensioner population whose triple-locked income is the one budget line no government dares touch, and the share of the national budget left over for actually building things shrinks every year, like a cake being divided by an ever-larger committee.

The fix fits comfortably on a Post-it note, which is presumably why the Treasury has never managed it: borrow for things that produce, not for things that are consumed. Where the money comes from matters far less than what it turns into.

 

The 1% Problem

Britain produces roughly 1% of global carbon emissions. For two decades the official theory was that this didn't matter, because Britain would lead by example: make its own energy expensive, shrink its own industry, and the rest of the world, deeply moved, would follow. The rest of the world watched this with great interest and then went on to burn more coal, oil and gas than at any point in human history. It was a bit like trying to persuade a stadium to sit down by sitting down yourself, in the car park.

The overwhelming majority of the world's future emissions will come from India and China, and not out of spite. Life expectancy at birth in India at independence in 1947 was about 32 years. It is now around 72. That is forty extra years of life per person, bought largely with fossil fuels, and no government in Delhi is going to hand them back because a minister in Whitehall set a very good example and wrote a very nice strategy document about it.

China is more interesting than the usual cartoon. It is building nuclear, wind and solar at a scale and price the West can only gawp at, and its emissions appear to have plateaued, possibly even begun to fall, over the last couple of years. But note how it got there. Not by using less energy, but by building so much clean generation that it started to crowd out the dirty stuff. China did not shiver its way to a plateau. It built its way there. Britain, by contrast, has mostly been trying to shiver.

 

The Central Heating Might Switch Itself Off

There is one climate risk that should concentrate British minds more than any other, and it gets remarkably little airtime. The Atlantic Meridional Overturning Circulation (AMOC) is the vast ocean current system that hauls warm water north and is the principal reason Britain has the climate of a mildly disappointed Mediterranean rather than that of Labrador. Recent research has raised serious concern that it is weakening and could pass a tipping point this century.

If it goes, north-western Europe gets dramatically harsher winters. Some estimates for London span something like minus 20°C to plus 35°C across a year. The exact figures are contested and the timing more so, but the direction isn't fanciful, and it quietly demolishes the comfortable version of "we'll just adapt". The Dutch can build dykes against a sea that rises a few millimetres a year. Nobody has yet designed a dyke against the Gulf Stream deciding to go elsewhere. There is no quantity of loft insulation that makes Surrey pleasant at minus 20, and I say that as someone who has seen what passes for loft insulation in Surrey.

Of course, the climate has always changed. Hippopotamuses once wallowed in the Thames, roughly 120,000 years ago during the last interglacial, which is a cheering thought until you remember that there was no Thames Barrier, no mortgage market and no national grid for them to worry about. Hippos adapt by walking somewhere else. Sixty-eight million people with a housing crisis do not have that option.

 

The Two Answers Available

Faced with all this, there are broadly two schools of thought on offer, and it is worth being honest about both.

The first is that humanity must drastically reduce its energy consumption, as a species, coordinated by some kind of global authority capable of making eight billion people poorer, voluntarily, forever, in unison. Its adherents, when pressed, will often concede that this will not happen, and that there are therefore no real solutions. This has the great merit of honesty and the minor drawback of being a counsel of despair wearing a hi-vis jacket. It also contains a category error. It takes a correlation, that energy tracks output, and treats it as if it were a constraint, that output requires carbon.

It doesn't. Output requires energy. Carbon is simply how we have mostly made energy so far. The entire march from hay to uranium is a history of changing the source of energy while the quantity kept rising. Which brings us to the second school of thought: make vastly more energy, without the carbon. One of these is a moral appeal to the whole of humanity. The other is a build programme. Humanity has a patchy record with moral appeals and a rather good one with build programmes, at least in countries that still remember how to run them.

And that, unfortunately, is where Britain's problem lies.

 

Why It May Already Be Too Late

In 2010, a senior British politician dismissed new nuclear power on live television on the grounds that it wouldn't come on stream until the early 2020s. It is now 2026. Hinkley Point C is still not generating. The fifteen years passed anyway, as years tend to; the country simply chose not to get any power stations out of them. It is the policy equivalent of refusing to plant a tree because it would take twenty years to give shade, and then complaining twenty years later that it is rather sunny.

The same pattern holds almost everywhere you look. Reservoirs, pylons, railways, housing, grid connections: each blocked, delayed, reviewed, judicially reviewed, consulted upon, redesigned and then quietly shelved in favour of a new strategy with a better font. Britain has developed a planning system of such exquisite sophistication that it can prevent almost anything, and a political system that has come to treat the prevention of things as a form of achievement.

So what would it actually take?

Cheap, abundant, clean electricity as the national priority. Not "net zero by a date", which is a target, but "the cheapest industrial power in Europe", which is a strategy. Nuclear at scale, standardised so we stop designing each reactor from scratch like a bespoke cathedral, renewables where they genuinely earn their keep, and a grid that can actually move the stuff around.

A planning system that assumes things will be built unless there is a very good reason otherwise, rather than the reverse. A country that cannot build anything cannot adapt to anything either.

A hard line between capital and consumption. Borrow freely for assets that make the country more productive. Be ruthless about any transfer that makes work irrational. Make sure the first job always pays.

Adaptation and mitigation, not a choice between them. Build the flood defences and the reservoirs, because the climate is changing regardless. And recognise that Britain's real contribution to global emissions was never its 1%. It is the chance to prove that clean energy can be cheap. A country that proves that will be copied. A country that proves clean energy means deindustrialisation and hosepipe bans will be politely ignored, which is precisely what has happened.

 

None of this is technically difficult. Every item on that list has been done before, somewhere, usually by a country with fewer universities and worse weather. The obstacle is not engineering. It is that each item requires a government to accept short-term pain, upset a well-organised constituency and wait longer than a single electoral cycle for the reward. That is the precise combination of qualities the modern British state has spent three decades selecting against.

Civil unrest, when it comes, will not arrive because of any single policy. It will arrive because a population has been told, year after year, that things are getting more expensive for its own good, while nothing visibly gets built and nothing visibly gets better. The remedy isn't a better speech or a new strategy document. It is a reactor, a reservoir, and an electricity bill that goes down for once.

Until then, Britain will carry on much as it always has: standing patiently in the rain, in an orderly queue, waiting for a train that was cancelled in 2011, quietly confident that the weather is about to improve. It is a very British way to go. One almost has to admire it.
