With apologies to TS Eliot…
A cold coming we had of it,
Just the worst time of year
For Dunkelflaute, and such a still one
The cold deep, and the weather sharp
The very dead of winter.
And the ministers restless, decisions delayed,
Budgets soften, like melting snow.
There were times we regretted
High system margins and abundant firm power
Frequency stable, inertia high.
Then regulators cursing and grumbling
And running away, and wanting the wind to blow and hard,
And the lights winking out, demand control in effect
And the cities hostile and people unfriendly
And the last gas plants open are charging high prices
A hard time we had of it
At the end we preferred the lost reactors,
To green delusions
With the voices ringing in our ears, saying
That this was all folly.
Then at dawn we came down to a new consultation
Weak, with wishful thinking, smelling of desperation
With a battery dead and a windmill still in the darkness
And pylons on the low sky,
And an old engineer slinks away from the office.
Then we came to a control room with ancient broken software
An office lit with vision statements, a bright-green new future
A grid without any spinning mass,
But there was no information, of how it would function
We pressed on, wondering if was always so weird
Finding the place; it was in no way, satisfactory.
All this was a long time ago, I remember
Would I could do it again, but set down
This set down
This: were we led all that way for
Birth or Death? There was a Birth, certainly,
Of a world without evidence and no shadow of doubt
But Death too, the quiet death of prudence,
Hard and bitter agony for us, blackouts and cuts.
We returned to our places, these fiefdoms
No longer at ease in the net zero assumptions,
With an alien people clutching their gods.
I should be glad of another way.

There are many strange myths and traditions relating to Christmas, some of which I have written about before (see below). The most special Christmas myths are the personal ones we create in our own families
2023
In days past, Christmas looked very different to what it does today. Many modern Christmas traditions originated in the Victorian era, but some had their origins in older traditions, legends and superstitions.
2022
Last year’s Christmas blog, while definitely tongue in cheek, was a little bleak, and this year has been bleak enough without adding more, however light-hearted. So, I thought I’d explore a slightly different aspect of energy

Had a certain Mr Dickens been around this year, I like to think that his Christmas-themed morality tale might have gone a little differently…

2020 has been a strange, horrible year, but one in which many of us have explored new ways of digital working. In that spirit, here is my slightly different Christmas blog (with thanks to my family for their artistic input). I hope you like it…

Scientists have been studying a rare phenomenon in the hope of developing new low carbon means of transport. First discovered in 17th century France…

According to The Week, the US uses an average of 6.63 billion kWh of electricity each year on Christmas lights – more than the entire annual consumption of…

This time of year is full of music, with carol singers out in force and the ubiquitous Christmas “hits” playing on loop in every store, but a recent discovery has brought music to mind in a different way…
2016
I’ve recently written about the work of the Energy Policy group at Exeter University, however another team at Exeter is exploring a novel way of transport which has significant benefits in terms of speed and efficiency,










Thank you, all the best in the festive season to you and yours and a great 2026! I appreciate your posts (and your replies on social media), I learn lots! Speaking of learning, in Manitoba, Canada, the hydro dams are about 1000km from where most of the electricity is consumed. The dams generate AC, it is converted to DC to transmit south to Winnipeg. The electricity gets converted from DC to AC at Dorsey conversation station, a few kilometres NW of Winnipeg. How does the voltage and frequency stay within tolerances in Winnipeg? Is there synchronous inertia involved? https://www.winnipegfreepress.com/our-communities/headliner/2017/11/20/dorsey-station-powers-manitoba-and-beyond
Hi Kathryn,
Thank you for all your insights into our electricity supply system. As a retired engineer I am appalled at the position we find ourselves in.
In a futile effort to reach net zero we are trashing our electricity supply system. Wind and solar cannot do the job without massive storage
capacity. We are reducing the inertia in the system and its resilience. We have insufficient generating capacity. We are locked into high
energy prices. Then we talk of Data Centres which are energy hungry.
That is enough for now!
Best wishes for Christmas

Hi Kathryn….big thanks for your in depth postings bringing to life the sorry state of UK energy security at this time. I concur with Douglas, we are in a mess how come we end up the Nuclear laggards of the western world ?
I live in a deprived coastal town, a close neighbour to Heysham 1 & 2 aging plants (2.6GW) still smashing it out after 40 years whatever the weather 24/7/365 with zero carbon emission from a relatively small 100 acre footprint. Big nuclear is the way forward IMO.
North Sea gas to Nuclear (N2N).
ITM Kathryn have a blog free Merry Sparkly Christmas.

Best wishes for Christmas and a healthy and happy 2026.
Thank you for enhancing my education in 2025 – I look forward to more.
Merry Christmas to you and your family too, and thankyou for the wonderful poem.
I am having trouble with the links to previous Christmas posts – is something broken ?
All the best Roger
May Gods give you a great power factor to combat the cultists hysteresis @
Merry Christmas, Kathryn. Great eulogy of the demise, and perhaps a hint of a hope, a resurrection? of our once great grid!
Thank you for all your hard work over the last 10 years+
Best wishes

Thank you Ms. Porter, you are a gem of the internet. Merry Christmas and a Happy and Prosperous New Year to you!
Will 2026 be the year we finally see intelligence and common sense prevail?
So grateful to be able to listen to such a credible and expert commentator on our Net Zero madness, when everyone else who wants to say something turns out to be pretty ignorant and biased.
Why is it that the media has to dumb down to their level, any technical matters they try to explore?
Been a pleasure to read your newsletters and watch your YT channel.
Please keep it up and I look forward to more insights in 2026.
Helps me keep my ‘balance’ !
Great work …
Thank you for your common-sensical science: Two things we seem to have lost in the last few decades: Common Sense and the following of Scientific Principles. For Watt gain? The creation of poverty and further impoverishment of the already poor? This was never my goal as a social scientist (aka Engineer).
Wishing you the best to promote your ideas well into the future! Happy New Year!
