You've not addressed a single one of my arguments, only replied to my conclusion, and doubled down on the arrogance despite being apparently less educated on this topic than me.

> But OK, I can almost hear you, "Electricity is special".

You haven't even considered, much less pre-empted, any of my arguments. Energy consumption is special - as it is required by thermodynamics for manipulation of the material world. It's clear that most of it will come from the sun eventually - but as I've pointed out there's reasons to expect this to take a very long time.

> So in half the time you're thinking about, the change was so enormous that the largest electrical generation sector disappeared, and a once insignificant alternative took their place.

Coal didn't disappear at all in that time frame - usage increased, significantly! But you only use the finished products now and don't see the cooling towers. UK economy is a rounding-error and not a meaningful model of the global energy economy, because wealthy countries like UK 'import' a huge fraction of their energy consumption. The energy required for their building materials, cars, machinery, consumer goods, etc still needs to be consumed somewhere - but it will never show up in local energy statistics. This represents the bulk of the hardest to electrify energy consumption. When you see a graph of fossil fuel usage increasing in India, China, Germany - do you not realise that is your personal usage too?

You first celebrate the fact that energy prices in UK have spiked (because lower profits for retailers, who recover their losses from whom ??), and now that UK has to import rather than produce steel (because it looks greener on paper ??).

> At sea all the short distance stuff will be electrified .. So then the question only comes up for the freighters

Ah yes, it 'only' comes up for the most difficult and energy intensive types of transport. You ignore air travel too.

Bulk carriers and freighters will continue to exist for structural reasons, and their usage will increase: manufacturing has natural network effects - it makes sense to geographically concentrate it (there is less duplication of expensive capital investment), more food will be transported as population booms in regions with less arable land, and biofuels/clean carbon sources will be transported just like crude because production will naturally be concentrated in regions with more arable land and sunlight.

Air transport will continue to exist because people want to travel, and it is the fastest way to deliver many types of goods.

> In 1985, so about 30 years later, Shieldhall was no longer economic

30 years at current rates is catastrophic damage to the planet, I don't understand why you want this. Also wiki says this ship was 'obsolete at time of construction', essentially built to be a historical novelty, and that it was laid down around the same time that the UK's first nuclear reactor connected to the grid.

> You've not addressed a single one of my arguments

I can't really make out any coherent argument. You seem to believe in a very strange nuclear powered fairytale world, which most resembles the video game series Fallout but you say you haven't played it, OK.

You demand that we should care only about the global picture, where the data is fuzziest, and only about the total energy system, all so far as I can tell in order to swell the focus on... coal, which is obsolete - that for some reason you both recognise can't be used because we'd destroy the climate and yet you believe we'll keep using it anyway because somehow the present is the future and don't accept that things change? I'm sure you think you're making sense.

It took me longer than perhaps it should have to see why you singled out Germany which in most ways is on a typical curve for a wealthy industrialized country. I realised it's the disappearing nuclear plants that make you angry. But they didn't matter, which I expect makes you even angrier. Germany's efficiency savings over that 25 year period were much larger than its total nuke energy buduget, what made the big difference was renewables again, just like in the UK.

> I don't understand why you want this

It doesn't matter whether I want things, it matters that your "argument" consists of believing that nothing changes = over a fifty year timespan no less - and I was illustrating that's entirely wrong.

[skew-aberration]

India, China, Germany are just examples of countries who burn fossil fuels to provide for your standard of living.

I explained, in some detail, why a) I expect decarbonisation to take a long time, on the order of 50+ years b) why the UK cannot be extrapolated to global economy c) Why it's not even true that UK residents themselves use less fossil fuels for energy than they did 20 years ago.

Instead of engaging, you try to read between the lines and psychoanalyse me while throwing juvenile insults. It's pointless, hostile, disrespectful, and frankly it says a lot more about the state of your mind than it does mine.

You claim coal is obsolete in 2026, the highest coal consumption year on record, in direct contradiction of the panels of global energy experts who have time and again agreed that these usages are 'hard to abate' (i.e unlikely to become obsolete soon). China expects to be using enormous quantities of coal (and gas) industrially in 2060 - their net zero plan hinges on capturing and offsetting the carbon released. What do you know that legions of global experts don't?

I'm all for decarbonisation, and I've likely dedicated far more of my time, effort, and money to that cause than you have. I think a healthy amount of nuclear in the mix (on the order of 25%) will bring us to net zero sooner, mitigate the enormous damage done to our planet, and help hedge our bets against future developments (as you point out, we can't really be sure how the economy will change).

Like I said, Germany is an example of the thing you say isn't happening.

In 2000 Germany uses about 14 exajoules of energy, somewhat less than 2EJ are nuclear electricity and the rest is almost entirely fossil fuels But in 2025 the 2EJ of nukes are gone, there are 2EJ of renewables and the total is now only 10.5EJ. So both the absolute amount and the proportion of fossil fuels fell in this period in which you believe the UK offshored some of its fossil fuel consumption to Germany.

This is a game of musical chairs and for maybe the next decade or two you'll be able to make increasingly contorted arguments that somehow the same problem was just moved, but it's already looking flimsy because of just how fast solar deployments are.

"Carbon capture" has been a pipe dream for decades at this point. If you don't have a plan B you don't have a plan.

[skew-aberration]

I'm pro-renewables, and I've worked, studied extensively, and invested in that field. There remain significant hard-to-abate uses (fact) which I believe (opinion) will slow down decarbonisation to a 50+ year timeline - this in line with the views of many experts.

> Germany is an example of the thing you say isn't happening.

I was wrong to include Germany in that list, it was an editing mistake hence why I didn't pick up on your reply. I can see that derailed the conversation. I only meant to list countries which were unlikely to decarbonise as quickly as UK due to a larger share of hard-to-abate uses (which UK residents still depend on), separately I was listing countries with increasing fossil fuels and I merged the sentences carelessly.

I chose Germany because I was looking at lists of exporters of steel and cars to the UK, not nuclear energy stats. As you point out fossil fuels have fallen slightly as a share there, not grown. I didn't say though that Germany isn't rapidly scaling renewables, you've just assumed I'm some kind of anti-renewable luddite. The fact remains you likely drive a car made with fossil fuels in Germany (I do).

You cite the 30% reduction in German primary energy consumption in 25 years as evidence against my prediction of decarbonisation taking 50+ years. In the same period, emissions have fallen closer to 40%. I doubt that the remaining 60% will happen in the next 25 years

* Germany did outsource hard-to-abate energy uses in this time frame (energy intensive industry production indices fell ~30%, 15% since the war, UK closer to 40% - both countries now manufacturer higher up the value chain, and import more high embodied carbon commodities)

* They did not decarbonise the remaining hard-to-abate uses in proportion to the 30% reduction you cite (cement is a possible exception). Closer to 10-20% max across a range of industries

* The biggest change coming in the next 10-15 years is the electrification of transport, which could reduce emissions by another 20+%, the so called 'easy-to-abate' uses.

* Hard-to-abate uses remain hard-to-abate - cement emissions decreased 30% in 25 years, it will be even more difficult to achieve the next 30%, let alone 70%.

A fall in the share of fossil fuels from 84% to 77% during a rapid 30% decline in heavy industry is broadly in line with my slow decarbonisation prediction - heavy industry is harder to abate than other uses, if you export it you can electrify faster.

Does 2EJ/year not matter to you or not? When it is energy savings or renewables, you say it is significant. When it is the reduction in nuclear power you say it is negligible. The proportional fall in fossil fuels in Germany you celebrate is 84-77 = 7% of the mix. (1/0.93 - 1) * 10.5 = 0.8EJ.

> maybe the next decade or two

I'm just predicting it will take closer to 50 years, not that it won't happen. In two decades you can just check global emissions - if they're down by less than say 2/3 I'll be right, there won't be any need to argue. If they're down 80 or 90% I'll be wrong.

> "Carbon capture" has been a pipe dream for decades at this point. If you don't have a plan B you don't have a plan.

China's 35 year decarbonisation timeline assumes CCS for approx 5-15% of today's emissions, up to 5x the UK's current emissions. Are they wrong about 35 years (too high?) or wrong about CCS (too low?) or both? They also expect 10-20 EJ/year nuclear. Are they wrong about nuclear too?
