My blog is 8 years old today!
The past year has seen my business develop in ways I did not expect even a year ago when I was celebrating my higher profile. I am still regularly quoted in the press and have written regularly for the Telegraph website, but the biggest difference is in the levels of engagement I am having and growing signs that my contrarian views are no longer quite so contrarian! This is greatly encouraging, not just on a personal level – this notice is translating into more business opportunities – but more broadly it provides signs of hope that hitherto unrealistic policy ambitions may be tempered. This week someone told me that I’m an energy “influencer”!
A year ago I noted that the discourse around climate policy had changed, prompted by the security of supply and affordability concerns emerging in the wake of the Russian invasion of Ukraine, a conflict that sadly continues. The trilemma was back with a vengeance and has not gone away – recently the UK Government announced a renewed desire to see the delivery of more gas power station this decade, despite the lack of available abatement technology.
“There are no two ways about it. Without gas backing up renewables, we face the genuine prospect of blackouts. Other countries in recent years have been so threatened by supply constraints that they have been forced back to coal. There are no easy solutions in energy, only trade-offs. If countries are forced to choose between clean energy and keeping citizens safe and warm, believe me they’ll choose to keep the lights on. We will not let ourselves be put in that position. And so, as we continue to move towards clean energy, we must be realistic,”
– Claire Coutinho, Secretary of State for Energy Security and Net Zero
But probably the most seismic change in past year came in July when the Labour Party failed to win the Uxbridge by-election as voters rebelled against the expansion of London’s emissions charging scheme known as “Ulez” (Ultra-low emissions zone). As a result, councils up and down the country abandoned plans for similar schemes, and the unpopular incumbent Conservative Party saw an electoral opportunity, shortly afterwards watering down the electric car mandate and plans for heat pumps. The Labour Party is not immune to climate u-turns having recently abandoned its green-spending pledge.
However, it hasn’t all been good news. In February I took part in IE Week, speaking on the final day of the conference in a session devoted to electricity. Too many of the speakers spouted out-of-date mantras about renewables being “cheap” and painting a naïve picture of a green utopia with green energy, green jobs, sunshine and flowers. I likened it to a child’s picture of a house – ask any child to draw such a picture and you get something along the lines of the image shown – charming, but hardly realistic.
When asked about people sitting in the cold and dark in order to save a few pennies under the Demand Flexibility Scheme, one speaker hailed the “social media buzz” they were generating, failing to recognise that they were driven by poverty and not a desire to be “down with the kidz”. However on a more positive note these remarks did not go down well with the audience, many of whom thanked me for being the “voice of reason” in the room. Still, we need to do more to avoid designing energy markets with the affluent in mind, while ignoring the reality of the majority.
The tone at the Flame gas conference this week was markedly different. Speaker after speaker stated, clearly and unequivocally, that net zero targets are unlikely to be met and that there needs to be a “plan B”. In the past, gas executives shied away from such statements fearing a “you would say that” response, and accusations that entrenched interests made their statements inherently unreliable. This is a common refrain from too large a segment of stakeholders, and just this week I was accused on LinkedIn of being funded by fossil fuel companies and essentially being a “climate denier” (and likely anti-vaxxer to boot!)
These more realistic statements also need to come out of the closet in the power sector. I hear time and again both directly and indirectly that senior executives in the sector share these views, but they need to express them in public so policy-makers can understand the likely failure of their targets. Indeed, at Flame, it was also noted time and again that success in meeting the targets, which are expressed in terms of territorial emissions, would likely result in wide-spread de-industrialisation as energy intensive industries fail to compete with exporters in countries with a less green approach to energy policy.
And despite the more positive tone from the UK Government, it has not been able to prevent further de-industrialisation in Britain, with the news that refinery activities at Grangemouth will cease and that the last blast furnaces in the Port Talbot steelworks are to close with the loss of 2,800 jobs. There are plans for the site to convert to the use of electric arc furnaces, but the loss of the coke ovens will see two thirds of the workforce made redundant.
As Dieter Helm points out, reducing our emissions in this way may well make climate change worse, since we will import more goods from countries with dirtier production methods and there will be an environmental cost to transporting them over longer distances. Helm is a big advocate of carbon pricing and believes that a strict carbon border adjustment mechanism (“CBAM”) – a carbon tax on imported goods that are not subject to the same strict environmental rules that we have – would deliver global results. But it would also be hugely inflationary, making goods significantly more expensive. While the EU (and a little further behind, the UK) plan to introduce CBAMs, I can’t help wondering if when the time comes, they are not weakened out of concerns over affordability.
Another key message from Flame was that while Europe had coped well with the near total removal of Russian pipeline gas from the market following the invasion of Ukraine, it had yet to be properly tested after two unusually mild winters. Several speakers also cautioned that there is now very little supply-side flexibility left in the market and that further disruptions would cause prices to spike again. Further escalation of the conflict in the Middle East would potentially threaten the ability of Qatari LNG to reach international markets and could lead to production shut-ins which would not be recoverable from elsewhere as other producers are already at maximum output.
There are also stresses in the power market. Ratcliffe-on-Soar, Britain’s last remaining coal power station, has announced its closure while the opening of Hinkley Point C has been further delayed. Up to 10 GW of firm, dispatchable generation may close by 2030, but only 2.5 GW of similar capacity is expected to open. Last year when I wrote my anniversary blog, I noted that there was almost no wind on the system that day – the same was true today.
Yet we still have celebratory social media posts from National Grid ESO and others when there are days that wind dominates. This is all very well, but it does not mean we have energy security, and it’s dangerous to be too excited about it, because days like today are not uncommon. And this illustrates very well why renewables are not cheap, because for every MW of wind and solar power that is installed, a corresponding MW of another form of generation or storage will need to be built to cover days like today. And at least twice as many grid connections will be needed with all the associated network infrastructure.
But the financial cost of renewables is not the only downside. Renewables are heavily resource intensive, requiring large amounts of metal. Metals are produced by digging or blasting rock out of the ground, and using heat and often toxic chemicals to separate the metals from the rock, leading to localised pollution, water shortages, and related adverse health impacts. Mining is also associated with labour and even human rights abuses. Public opposition in mineral-rich south America is growing, which is threatening the supply chains for renewable generation. And, while these metals are also used for conventional generation, its higher energy density means that much less of it is needed per MW of capacity and per MWh of electricity generated. Renewables, and in particular off-shore wind, are inefficient both in terms of capital and resources.
More people are now accepting that renewables are not cheap. I hope that they will also start to realise that the environmental cost of extracting the critical minerals required is also an important consideration. I have often advocated for a more holistic approach to sustainability that goes beyond just carbon dioxide, and with material costs rising, and growing concerns over Chinese dominance of supply chains, it is to be hoped that policy-makers will start to focus on using financial and material resources in the most efficient way. And this will inevitably point to nuclear power as the optimal solution to the de-carbonisation challenge. The recent renewal of interest in atomic energy is a reflection of its high energy density and reliability, with several countries including the UK re-starting their nuclear programmes.
The increasing realism about the sector is positive but there is still a way to go – there are still fanciful ambitions to create an EU-wide hydrogen pipeline network for example, and there is still insufficient honesty from policy-makers about the costs of the energy transition and the impact on living standards it will have. The green utopia is all very well, but the reality is that the energy transition is delivering neither cheap energy nor a lot of green jobs – the US which has seen a record-breaking increase in fossil fuel production in recent years enjoys both cheaper energy and higher economic growth than Europe and the UK. This is not a co-incidence since access to cheap energy is a major driver of economic growth.
The energy transition is not going to deliver the beautiful and naïve ambition of green energy and green jobs and there will be no successful green industrial strategy. This is not a licence to pollute, but it does require a re-calibration of energy and economic ambitions, and the UK and Europe must decide how far they are willing to go to reduce territorial emissions when they are just a tiny proportion of the emissions that will come from Asia and Africa as they continue to develop.
And as Dieter Helm points out, 28 COP gatherings have singularly failed to deliver any reduction in global carbon dioxide emissions – indeed, since the 1960, only the 1990s saw any reduction in average decadal concentrations, and that reduction was more than wiped out in the subsequent decade. Of course, some would argue that without the interventions of the past thirty years, atmospheric carbon dioxide levels would be higher, but the question is by how much, and whether the cost of these actions is justified.
It is likely that policy-makers will need to pivot from devoting all their efforts to prevention, to considerations of mitigation, and while the results are clear, the consequences in terms of climate impact are not. Many people believe we are on track for warming in the 2.5 – 3.0oC range, but climate models are notoriously unreliable. In any case, the only thing Europeans could do to meaningfully impact global emissions would be the imposition of strict CBAMs, and that would come at a high cost, potentially higher than its voters will be willing to accept.
It will take time for these realities to sink in, but we are finally moving in the right direction. Hopefully the next year will see further progress. Here in the UK, there will be a General Election that will force all political parties to develop fully costed manifestos, setting out the trade-offs they intend to make across all areas of policy and the economy. There’s nothing like financial accountability to concentrate minds – it will be interesting to see how energy and climate concerns influence electoral posturing and whether the indications of public displeasure in Uxbridge will influence the Election outcome. Energy markets are never dull and the coming year may well be more interesting than most.

I would like to thank all of my clients, colleagues and readers for their support over the past year. Despite being a sole trader, I feel I have a very large number of colleagues, and I would particularly like to thank the people in my network who are ready to offer help, advice, information and moral support, and I am always happy to reciprocate. It’s fantastic to be part of several international energy networks, sharing ideas and helping each other with market insights.

“You can avoid reality, but you cannot avoid the consequences of avoiding reality”
– Ayn Rand
Thank you Kathryn for your excellent, and realistic, posts. I read every one.
I am hoping that politicians will start to water down some of these commitments when they realise the public will not tolerate their lives being made more expensive and inconvenient as a result. One small example is my local station car park where 10 spaces have just been converted to electric charge points. Yesterday these spaces were empty and the rest of the car park was full. Don’t think it will be popular!

There is no argument that we cannot transition to an electrical grid powered just by wind and solar with some nuclear. That is one realism.
The other is that reducing CO2 output is not going to alter the climate. More and more evidence of this is coming from scientific research and knowledge.
That the U.N. is one of the most vociferous claiming that we must reduce CO2 and also having stated as Ms Figueres did in a speech words to the effect that “It is amistake to think this is about climate but to dismantle the economic model that has existed since the start of the industrial revolution.2
I suggest the U.N. are well on their target to destroy or Western economies?
IR said “There is no argument that we cannot transition to an electrical grid powered just by wind and solar with some nuclear.”
An all wind and solar UK grid would need enough wind and solar to provide around 120% raw wind and solar generation compared to demand each year. Plus around 8 hours (300 GWh based on current demand) of grid batteries, 2 to 3 months of green hydrogen storage, 50 GW of hydrogen fired CCGT (converting all the current natural gas plants and adding some more) and around 15 GW of electrolysers. The green hydrogen storage would consist of around 8-10 converted depleted oil or gas wells of the volume of the UK Rough natural gas storage. The addition of some nuclear would reduce these resource requirements a little.
IR said “The other is that reducing CO2 output is not going to alter the climate. ”
True. To restore the climate back to what it used to be, we need to remove CO2 from the atmosphere. BECCS is one relatively cost effective way to do this right now, but we need to get close to zero emissions before it is worth doing it big time. If technology advances enough then wind and/or solar driving direct CO2 air capture plants might be cheaper.
But there is plenty of evidence from the last 50 years than human induced CO2 emissions have added 50% CO2 to the atmosphere and increased temperatures by 1.2 to 1.6 degrees C already. The ocean heat content stats are the clearest graphical presentation of what has happened. See https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content
Morning Katherine. Very interesting post and accords with my views on fuel replacements for larger vehicles – mostly impractical or cost prohibitive to cash strapped public services.
Hello Kathryn, thank you for this excellent review. These words of yours particularly resonated with me, “Still, we need to do more to avoid designing energy markets with the affluent in mind, while ignoring the reality of the majority.”
Minor typo at the end; the quote is from Ayn Rand rather than Ann Rynd.
Many congratulations on your 8th birthday.
Regards, John C. (elec m/c engineer (ret’d.))
Thanks, fixed the typo!
Kathryn your email was the first one i went to at breakfast as i just enjoy your thought provoking blogs and good to hear that whilst your time for them may have diminished its because you are out “influencing” which is far more important.
I fear its going to be a long haul to row back from where we have got to though. Too many people ive discussed this matter with have been heavily contaminated by the green blob although majority don’t want to change their lifestyle much more than marginally so in the long run this maybe where the pushback ultimately comes from. So yes there is some movement but a long way to go and I fear a Labour govt may prove to less inclined to row back, at least initially, but at some point reality will set in but depends on how much damage is done. We also need to be careful about rowing back really means. Take ICE vehicles Tories accused of being environmental vandals but the reality is they didn’t alter the Zero Electric Vehicle mandate requirements which this year requires 22% of vehicles sold to be BEV and are already below target at 15% ytd. Any manufacturer missing target will face financial penalties so whoe going to pick up the tab for that. Oh and and the percentage increases yearly to 80% by 2030 its pretty clear its unachievable but why was there no pushback by MPs? Already Stellantis (Vauxhall) MD is threatening consequences if its not changed and then we may see big importers giving up as well and all we will do is cede this market to the Chinese as well.
Anyhow keep promoting reality when you can
“… many of whom thanked me for being the “voice of reason”” – amen to that. We need more calm and rational discussion about this whole topic of climate change, the reality, the true risks and practible mitigation options. These posts are a great counter to the herd-mentality, near-mindless hysteria demonstrated by many lobby groups / individuals, made worse as they won’t tolerate challenge. Please, keep them coming – I find them invaluable. The tide, as you note, is turning at last but it’s a tough gig.
I too have noticed a slight wobbling in the Green commitment. Yet opinion within the chattering classes has not really moved much. The mandate, for example, for battery electric cars seems more or less unchanged. There has been no clear instruction to finish Hinkley C quickly. Small modular nuclear is hardly supported and there is no sign that we have a way to get new gas stations. The ONS social survey reports:
❝When asked about the important issues facing the UK today, the most commonly reported issues were: the cost of living (87%), the NHS (86%) and the economy (70%); other commonly reported issues were climate change and the environment (61%), housing (55%), crime (55%), immigration (51%), and international conflict (50%).❞ (https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/10to21april2024)
We are still sleepwalking towards vezry bad outcomes (on many fronts).
The Government does seem to be committed to new nuclear. The recent Hackathon was interesting as was the fact they have clearly been following up, so I think the efforts are sincere. Whether they will be effective remains to be seen, but the first step of intent is there.
The trouble with polls is the results very much depend on the questions asked. If you ask someone “do you care about climate change/the environment?” they will say yes – what type of a @#*?@! would say otherwise! But if you ask “are you willing to pay more for goods / energy / have a lower standard of living in order to protect the planet?” you are likely significantly less enthusiasm.
So far net zero policies have had very impact on people – energy became more expensive but this was largely masked by an extended period of cheap gas. When gas became more expensive, energy quickly became unaffordable. The next steps – heat pumps and the CBAM – will have a MUCH bigger impact, and the more that impact looms, the more I expect politicians to hesitate.
Hi, just a correction:
You have misspelled Rand’s name at the bottom of the article (the final quote). It is Ayn Rand, not Ann Rand. 🙂
Thanks, now fixed.
Congrats on your 8th business bday , it is quite an achievement.
It’s a shame, I dont often read your blog thoroughly anymore.
Happy Birthday to your Blog Kathryn. I enjoy your posts and your other writings and appearances in he media. Great work, valuable insights.
Congratulations Kathryn – a pleasure to read your views – so much more insightful than many. Cost of energy and resilience in supply are such key components of our economy we are left to wonder how our Government is so incompetent. Surely the last few years have shown where reliance on modelling have taken us. Many, many countries have abundant supplies of coal. I find it impossible to believe that we do not posses the technology to burn coal cleanly. The Voyager spacecraft launched in the mid 70s, so arguably with 60s technology is 15 billion miles from earth and still going….but we can’t burn coal cleanly. Really!
Our electric use is about 36 gig. Within 2 years China will have installed 1000 gig of Solar alone.
Hi…..worth a read.
https://open.substack.com/pub/robertbryce/p/what-media-wont-tell-you-about-energy-transition?r=31whpy&utm_campaign=post&utm_medium=web
Best…..Barry Wright, Lancashire.
I would not recommend that article. It is highly selective about the charts it shows, and misses out some crucial information, to make some sort of dogma point.
Specifically, the article says that China (with the largest grid in the world) is doing nothing except installing more nuclear. As a 2024 article it completely omits the fact that China installed 292 GW of wind and solar in 2023 – as much as the rest of the world put together. It thus lies about China not being serious about the energy transition. If China can grow its wind and solar installs by another 30% or so, compared to 2023, within the next few years, then it will start to bring down coal use on the Chinese grid in 2025 or 2026. It could even be this year, but that might be a stretch, and relies on low GDP growth.
It is true that China is installing more coal plants. But these are required to cope with increasing peak hour demands, because wind and solar aren’t guaranteed to be generating during these peak time. But installed coal capacity growing is not the same thing as coal generation growing. Even once generation from coal starts to reduce, we will probably see China install more coal capacity, because China uses coal instead of gas to back up wind and solar.
On the matter of gas, the article is pretty silent. That is because the USA is still installing a lot of gas (which is not clean because it still has half the emissions of coal). In fact the proportion of coal generation in China is only a little higher than the proportion of coal and gas generation together in the USA.
None of the western countries are installing wind and solar at anything like the pro rata rate that China is, whether you pro rata it by population, GDP, cumulative historical CO2 emissions or current CO2 emissions.
So the article is a “pants on fire” purveyor of misleading misinformation by omission. This is the sort of thing that may well be financed by fossil fuel money to persuade those of us in the west not to bother with the energy transition by falsely saying China (etc.) aren’t bothering, which is totally false.
Hi Barry. Somehow it seems to have name as the author of the comment. But thanks for sending it
Hi Julian……not at all, you’re welcome.
Watt-Logic Blog & the excellent topics thanks to Kathryn will always be my first choice, long may it last.
However I do like the American online platform Substack, provides a measure of balance IMO.
Thanks to a Peter Mott posting (13/11/2023) I was introduced to articles by Jack Devenney of the Gordon Knott Society which got me interested in Substack. Jack is a regular contributor on all things nuclear from a global perspective; interesting guy.
His devotion to solving the Gordian Knot of our time; the twin problems of energy poverty & global warming knows no bounds.
I lifted the posting referred to as worth a read from the Substack forum.
Hope this clears things up……regards…..Barry.
It’s been very informative getting a regular briefing from an energy industry insider.
With politicians, they like to promote certain routes because it allows them to say, look what I have done, even if it isn’t the most efficient way. Just like the “legal obligations” to get to net zero.
I agree entirely with your arguments against deep off-shore wind as it is one of the most expensive forms of renewable power, unfortunately, but some renewables are getting cheaper all the time, and the problem is the lack of recognition of the way the generation mix should be adapted to get consistent output, and the most economically viable forms.
Wind is unreliable, and should be seen as a back-up to solar, which is the most consistent. This should also be reflected as the best way forward as solar is the cheapest renewable energy source, and one of the most reliable.
Unfortunately for home owners, the installation of solar power is not tax deductible, which it is for commercial solar, so economically, the homeowner has the negative impact of the tax regime which is skewed to commercial installations.
Renewable energy can be cheap, very cheap, but you do need a government that understands the explicit structural economic biases that confounds the installation of the most efficient form of renewable energy.
If we had enough solar, installed on roofs, we wouldn’t need any gas generation during daylight hours for most of the year………..who wouldn’t want that?
Cheap power and lower emissions, based on some aluminium, sand and a small amount of other rare earths.
If you want expensive electricity, then yes, by all means go for deep off-shore wind, and others. I’m just waiting for legislation that dictates that all towns/villages have to have one or two wind turbines, sited locally. Perhaps if we didn’t have wind farms and solar farms, taking up acres of good farming land, with all the extra grid infrastructure needed, perhaps we could get to use smaller quantities of minerals and metals, but so many people just don’t like the idea of efficiency if it “spoils their view”.
There are many windturbines (windmills made from wood) that used to be essential for the local production of food and the local economy, around the local area of outstanding natural beauty, but why are people so against a modern efficient version?
There’s nowt so queer as folk.
Renewable power can be cheap, and could be cheaper than it is now, but we do need a government that doesn’t just stick to the same tired old economic models of the last 300 years since the industrial revolution started.
The trouble with solar is it is at best a means of reducing cost in the summer. It makes zero contribution to security of supply because peak annual demand occurs at night. It is also hard to source solar panels that do not involve China where labour and environmental practices create real ethical concerns. I personally would not recommend buying Chinese solar panels even if alternatives are more expensive. The production of rare earths is even more problematic – becuase they are chemically similar, they are very hard to separate. Only China has the appetite to engage in these processes as they generate a lot of highlt toxic waste with major environmental consequences.
I doubt renewables will come down in cost because of the supply and demand dynamics in the supply chains.
The capital cost of solar is going to come down by about 15% within a year or two as tandem perovskite solar cells go into volume production. The second junction pushes up the efficiency by around 15% – with plenty more to come from other tandem perovskite techniques. At optimum it could go as high as a 50% hike on the limits for a single junction solar cell.
Oxford Uni and Fraunhofer are going to start volume production later this year. Efficiency is not too difficult, but stability was always the issue, and they appear to have cracked that.
With similarly priced panels, but higher efficiency, the rest of the system costs are pretty similar, but the output is higher. Will end up changing the cost case for both utility and smaller scale, including rooftop solar.
And the change to glass-glass panels away from plastic backing sheet is extending their lifespan.
Solar panels have consistently shown the greatest (steepest) learning curve. I don’t know if it’s actually started to flatten out yet or not. There may still be significant gains to be had from technological developments, which cannot be achieved with any other technologies, except fusion.
Price reduction curves are always subject to a degree of noise from demand changes and supply chain developments. You can’t necessarily tell what is going to happen short term.
It certainly doesn’t look as if solar PV power price reductions are going to bottom out for a decent number of years yet. Tandem perovskite cells will probably drive another 50% reduction eventually – both in utility scale and rooftop solar PV.
Another technology pretty certain to reduce considerably in price is floating offshore wind. In theory it should be broadly comparable in price to bottom fixed offshore wind, but at the moment it is considerably more expensive, but with very limited volumes right now. Give it 5 years and we will see where contracts are heading.
And you would expect cheap sodium ion battery cells to bring down the price of grid battery storage (BESS units) considerably, over the next few years. That is not the reason why CAISO California (>10 MW right now) and ERCOT Texas (expected to have 12 GW by end of this year), are competing to be US battery storage top dog, but it will certainly encourage them to install a whole load more to support the 40+GW and 20+GW respectively of solar PV they have right now.
Then the 1.2 TW pipeline of green hydrogen projects is bound to have a huge effect on the price of electrolysers, given we have ~ 1 GW in operation right now. Don’t know how long it will take but it has to come.
Kathryn doesn’t seem to see these renewables improvements coming. She might be right about temporary supply chain disruptions to solar panel supply pausing temporarily because of reluctance to shop for them in China.
That doesn’t seem to leave much! Hydrogen fuel cell technological improvements and price reductions would be nice, but I am not holding my breath right now.
Peter, I think you are spot on.
Is it a question of faith?
Having worked in R&D on some very demanding technologies, you get a feel for the possibility of change, and can extrapolate certain trends and for certain technologies know that there are considerable possible variations that can allow for significant improvements.
I think part of it is that with renewables, especially the financial aspects, involve non-linear dynamics that if you add in one change, that there are subsequently multiple changes to the financial aspects of every other technology in the system, such as just the use of solar panels has a knock on effect to the LCOE of CCGT because you change the way you use, or the frequency of use of other power generation technologies.
Solar panels aren’t suitable for every residential property, as someone else has kindly pointed out, but if you can make them last twice or three times longer than previous generations, capital expenditure rate changes significantly…….put that in your LCOE pipe and smoke it. The environmental aspects change as well. 3x longer – gives 1/3 minerals needed. For some things, it isn’t just the instantaneous efficiency where the gains are made, unlike wind power, which has a more usual development curve, where there’s almost a direct link between efficiency/size and capital expenditure.
Solar Panels are completely different to many other technologies, in terms of their development, but the petrol engine is a good example, where you used to have rebores at very low mileages because of the poor lubrication, but with modern synthetic oils getting an engine to last 1,000,000 miles is a lot easier. Lubrication has moved on considerably in the last 50 – 70 years, and corrosion protection. My current car is 24 years old done 187,000 miles and still going strong, whereas my first car rusted through in 12 years having done 90,000 miles.
About 30 years ago. No comparison really.
Perhaps too many people have been used to the designed obsolescence built in to many products, or the limitations of specific technologies where each renewable power technology is actually a combination of multiple technologies, each of which is slowly being honed and improved to get the step by step efficiency improvements overall, and now, where we need to concentrate efforts on built in longevity to reduce CAPEX.
It does make me wonder if part of the problem with wind turbines is that the manufacturers, like VW with one engine I know very well, didn’t do very well on their original lubricant specifications, and are relying on old technology/specifications that may be suitable for smaller turbines, but they need to really think again……..just a thought.
Tim Stone. “If we had enough solar, installed on roofs, we wouldn’t need any gas generation during daylight hours for most of the year………..who wouldn’t want that?”
I wouldn’t. Nor would any owners of thatched cottages or houses which have other aesthetic values. Nor do I want renewables forced down by my throat. For what? A non-existent climate crisis dreamt up to destroy western economies. The climate models are laughable – about as reliable as the average economic forecasting models as used by governments around the world. And those climate models are not independently coming to a similar conclusion – the researchers collaborate and swap data, and are careful to ensure their model is not out of line with others and the prevailing academic “consensus”. It would be hilarious if it weren’t so serious. I cannot make up my mind whether those pushing this green/net zero agenda are stupid or evil. Probably a bit of both.
I take extra pleasure these days from having a woodburner and roaring down a quiet motorway at a speed which really shoves the CO2 into the atmosphere – my little fightback against the puritan tide. And it’s good for plant life too!
PS Thank you, Kathryn, for your piece (while not implicating you in my considered opinions)
“The climate models are laughable”.
This is demonstrably wrong. See this article (https://www.carbonbrief.org/analysis-how-well-have-climate-models-projected-global-warming/) for a review of how climate models from the 1970s and 1980s have fared. The answer is – all were pretty much in line with what has happened. In fact what is happening is more or less in line with predictions by Arrhenius in 1896 (note the century) and Callendar in 1937.
“I cannot make up my mind whether those pushing this green/net zero agenda are stupid or evil. Probably a bit of both.”
How about another possibility. They are very concerned about unconstrained warming of the planet, and they understand the physics a bit better than you? If we don’t achieve net zero then the temperature of the planet will continue rising.
“I take extra pleasure these days from having a woodburner and roaring down a quiet motorway at a speed which really shoves the CO2 into the atmosphere – my little fightback against the puritan tide. And it’s good for plant life too!”
I take pleasure in driving too. But in a car with far superior acceleration to yours, that is quieter and cheaper to run and which – having been charged by sunlight – barely warms the planet.
Best wishes
Michael
Michael – you do know that Kathryn’s degree was in Physics? I suspect she has a far greater knowledge of physics that most of the staff at carbonbrief. Of course you are inclined to think that with your career at NPL you are one of the only ones who understands these arcane matters. There are large catalogues of failed climate model predictions. A few from James Hansen include an ice free Arctic, parts of New York city under water, and far greater temperature increases than even GISTEMP shows – all by now or earlier. Serious climate scientists have been wrestling with the problem that many models run too hot. Perhaps you should look at that work rather than the propaganda?
I hope you have accounted for the minerals mined to make your Tesla in your evaluation of its environmental impact. I bet you don;t keep it until the 80,000 mile breakeven.
Hello Kathryn, I tried to leave the following message this morning but was told that I had already done so! However, nothing appeared even after several hours and so I am having another go. Cheers! John C.
“Hello Kathryn, thank you for this excellent review. These words of yours particularly resonated with me, “Still, we need to do more to avoid designing energy markets with the affluent in mind, while ignoring the reality of the majority.”
Minor typo at the end; the quote is from Ayn Rand rather than Ann Rynd.
Many congratulations on your 8th birthday.
Regards, John C. (elec m/c engineer (ret’d.))”
Sorry John, your post went into moderation and I was busy earlier and didn’t get the chance to log in until now.
Happy 8th birthday, Kathryn. I always enjoy reading your stuff and I’m pleased it gathering more traction.
Hello Ms Porter. Happy eighth. Good going.
What did you think of Climate:the movie? We still need to talk about energy security even after we drop co2 as the bogeyman.
With “little supply side flexibility”, doesn’t that confirm that we actually need to get as much cheap renewable power supplies installed as soon as possible, such that our dependence on imported gas is reduced?
Yes we can drill for more in the North Sea, but all estimates are that it is now totally insufficient to meet our needs and we are dependent on imports.
And “could lead to production shut-ins which would not be recoverable from elsewhere as other producers are already at maximum output.”
Doesn’t this all mean that we desperately need more renewables to decrease our dependency on supplies that will at some point in the future become unreliable and economically risky and expensive?
It’s OK to say, let’s keep burning gas, but what if the supplies become as variable as the wind itself? Or the cost becomes just as variable as the supplies, as we have seen all too recently.
Do we want to be in a situation of choosing between gas for heating or gas for eating, where it is used for fertilizer production?
There are other consequences to which many people appear to be completely oblivious.
I like burning gas, my central heating uses gas, I even run my car on LPG (Propane), but sticking to just Natural Gas isn’t actually as rational as it may once have been, not because of climate change, but because a greater proportion of the world is concentrating its dependence on the same commodity.
But I’m actually investing in technologies that give me an economic return and improve my own resilience to possible supply shortages. There’s always enough, until there’s a shortage.
Our gas supplies are very comfortable. Even at the height of the crisis we were never in any danger of not having enough gas. It is a misconception that renewables are more secure than gas, it is not true – gas might become expensive, but we are still a rich country and very able to outbid many others who want to buy gas. Our LNG terminals have more than enough throughput to satisfy cold spells, combined with our domestic production.
The impact of further supply side disruptions would be increase prices and countries such as Pakistan would have failed tenders again as they did in 2022. We don;t need to buy all the gas, just enough for our needs, and the reality, however harsh, is we can afford it. It might be uncomfortable, but we absolutely can afford it. There is no prospect of a supply disruption in the UK, just a threat of high prices.
Regarding security, we all know that renewables are variable it is not that they are more secure than gas, but if you have only got say 2 TWh of gas supply, and you need to create 1 TWh of electric, at say 50% efficiency if you displace the use of gas where possible with renewables, (ignoring gas for heating), however variable they are, you can end up with only needing 1 TWh of gas, giving 1 TWh gas buffer. It doesn’t matter if you do have an alternative power supply that is variable, if there is a risk of only getting say 1.5 TWh of gas, when you need 2 TWh.
The variability doesn’t matter if you are able to mitigate a shortage with respect to the total annual demand.
The variable renewables mitigates the supply constraint of gas, even though the renewables are not entirely dependable/secure.
Earlier this month, the gCO2/kWh was down to 19, i.e. just 0.9GW of electricity being generated by burning gas out of 35 to 40 GW total demand. They were having to cut back the electricity imports to cope with the amount of renewable electricity being generated.
If China starts to import more gas, what will happen then? They’ll get it from Russia first, that we’ve stopped using, but even the Chinese might get pressure to improve the air quality of their cities and to move away from coal.
There are many economies that are really starting to crank-up, like India, so whilst we may be rich, decisions and contingencies now may be critical in 10-20 years time. And this is completely ignoring anything about climate change!!
In your analysis, are you absolutely certain that other economies are going to remain in their current state and have the same current demand, and have the same affordability issues? I wouldn’t be as certain as you appear to be.
Happy 9th anniversary.
Let us examine “for every MW of wind and solar power that is installed, a corresponding MW of another form of generation or storage will need to be built to cover days like today”.
This is a big fallacy.
My simulation of the Texas ERCOT grid for 2010 through 2012, using actuals required 155 GW of wind and solar, 60 GW/300 GWh of grid batteries and 30 GW of hydrogen capable CCGT (with sufficient stored hydrogen to generate 14 TWh of output via CCGT) to meet 100% of average demand of 40 GW and peak demand of 71 GW in those years. The simulation included storage efficiency losses, but not normal grid transmission losses, which would likely push up the required wind and solar GW a little but cause a smaller increase in the despatchable gen + storage power output GW.
So wind + solar of 155 GW, and storage + CCGT of 90 GW. This isn’t anywhere close to a GW for GW match.
By the time you include simulations of a decent level of industrial demand response and EV smart charging, the ratio is likely to larger too.
It should be intuitively obvious that the two aren’t going to match, because the despatchable generation + storage power capacity required is mainly related to peak (assumed inflexible) demand, while the required GW capacity of wind and solar will depend on both average demand and the capacity factors for wind and solar.
“You can avoid reality, but you cannot avoid the consequences of avoiding reality”.
I agree. And the reality that you and most commenters here seem to be avoiding is the reality of Climate Change. And we can avoid that reality – as we have collectively for decades – but we cannot avoid the consequences. And with Net Zero the choice is very simple.
Achieving net zero emissions of carbon dioxide is the only way we know to stop the temperature of the Earth rising indefinitely.
So if you are against net zero emissions, you are in favour of continued warming of the Earth, with catastrophic consequences.
Best wishes
Michael
All this is very true – we don’t have that much of a choice if we wish to address the remaining CO2 emissions from the UK grid.
But what is also true is that the economic projections for a net zero GB grid (excludes Northern Ireland, so not UK) in 2035 indicate that the cost of electricity to consumers, in constant currency, is likely to be somewhat less than the cost of electricity to consumers of the current GB grid.
Thank you.
It’s not a case of being against net zero, but against the current net zero policies which are failing to do anything to address global climate change since they are purely territorial in nature, and the CBAM, when it comes, may be watered down due to cost and inflation concerns.
A more efficient approach would be to massively subsidise nuclear power instead of renewables, and to have a properly researched approach to reducing energy losses from buildings and in processes. We need affordable domestic energy, which is not going to be delivered by anything intermittent. Ensuring cheap domestic energy will mean we sustain industries, removing the need to offshore production and pollution to other countries.
Opposing a policy that is not working does not equate to being indifferent to climate change!
As a country, there is another important point regarding how we generate power, again ignoring climate change as an issue.
You said “The impact of further supply side disruptions would be increase prices and countries such as Pakistan would have failed tenders again as they did in 2022.”
Morally, shouldn’t we as a first world country be adapting our demand for natural resources in positive ways such that other less wealthy countries don’t have to face harsh realities that our wealth protects us from?
If we can install renewable/power generation technologies that reduces our demand for gas, not such that we kill our economy, but where it is economically feasible to do so, shouldn’t we be doing all that we can to attain that objective?
Forget about climate change for a moment again, just taking the consideration that there are countries that from time to time fail to get the resources they need because they cannot afford the price because of the shortage of supply pushing up the prices?
Do we really want to be a country that has lost its way morally?
There are many more issues around gas supply and power generation other than just climate change. Of course other countries should be doing the same, to protect their own population from the harsh realities of gas shortages and high prices, but how many people are only looking at the one issue of climate change and missing other important economic factors and effects?
There are two strategies for taking risks and managing risks
1) Diversify (don’t put all your eggs in one basket)
2) Concentration (put all your eggs in one basket) But watch it like a Hawk.
With dependence on one commodity GAS, you can watch it like a hawk, but that does nothing if there is a shortage/supply disruption……war, terrorism, weather, accidents, mechanical failure, etc etc.
If we aren’t burning coal any more that could be dug out from the UK, we have to have diversity, any thing else is just too risky. Again all this completely ignores climate change. Importing COAL would carry the same risks as importing GAS.
What would you do?
Diversity of power sources isn’t a choice that you can avoid if you think through all the consequences.
Renewables are very inefficient. We would be better off building a lot of nuclear power.
I agree that out-bidding poorer countries is not desirable, but it is an economic reality, And it’s not immoral to protect our own population – 6-8k people die on average every winter in the UK as a result of fuel poverty. Winter blackouts at night would also kill people. Building lots of renewables involves ore mining which destroys the local environment around mines, harming the people who live there. Energy policy choices are not welfare neutral.
We should base our power system on nuclear (with a handful of technologies to diversify risk) and gas since that is cleaner and a better use of resources on a lifecycle, delivered firm power basis than any of the alternatives.
“Renewables are very inefficient. We would be better off building a lot of nuclear power”
The risk to infrastructure couldn’t have been more critical than following the Great War, yes it’s that long ago. Nearly every town had a power station, cities had several each supplying their local network.
In the following years the UK embarked on the building of a 132kv national grid network with national security a priority.
Power plants, control centres, munitions factories could now be sited in discreet locations away from highly populated areas.
Overhead lines & towers wherever possible sited off the skyline 100’s of miles almost obscure in the landscape.
Just as well the programme was ramped up as the the 2nd world war loomed.
Built more for a country at war it became obvious come 1950 that the original 132kv was at capacity & never designed to carry power in bulk around the country.
The original 132kv grid served us well for some 30 years including the German Blitzkrieg.
The forward thinking British Electricity Authority (BEA) committed £52m (£1.4b today) over 10 years constructing 1150 miles of new 275kv supergrid transmission lines. What’s more engineers had greater ambitions with foresight to match, building towers that could easily accept heavier 380kv lines in the 1960’s. Insulator technology advanced & 400kv was eventually used. Transmitting power in bulk across the UK is a story of remarkable engineering prowess & transition. Yes moving energy via overhead lines to areas of high demand did have cost implications, but at the time it was considered much cheaper to transmit electricity over long distances rather than transport coal.
The first circuit-breaker was closed to energise Britains 275kv supergrid for the first time in 1950.
Many of the original routes continue to reliably transmit power today on towers erected 70 years ago.
National Grid (NG) are taking the lead re tomorrows network connecting us all to clean energy via new infrastructure in new places.Today new technology & innovation are already driving the clean energy transition bringing low-carbon electricity to millions. One instance is the London Power Tunnels project reflected here in the north west. NG have lodged a planning application for a power tunnel beneath the waters of Morecambe Bay to cater for the output from the part constructed Moorside nuclear power plant at Sellafield. NG are spending billions helping Britain to reach net zero. All based on that original power network, a model that served us well for 100 years.
A robust high capacity supergrid will always be central to energy security in Britain IMO a small island with a population approaching 70m. Continuing development of transformers & switchgear hopefully from British manufacturers collaborating as in the past leading to a rapid pace of progress. Bulk oil/air-blast circuit breakers 7,500MVA early designs were quickly replaced with 10,000MVA & later 15,000MVA ratings during the 1960’s, SF6 breakers very much in their infancy at the time. ESO also played a large part with the reduction from five regional control centres to one.
Be assured the Great Grid Upgrade, the biggest overhaul of our electricity grid in generations once again is well under way ready to transmit the output from big nuclear, pumped hydro, CCGT, renewables, etc.
Barry Wright, Lancashire.
To deal with war risks of targeted strikes, coming back to nuclear power, you actually need a SMART grid that, like a brain neural network, can reroute and rewire itself, and have numerous power supplies, such that the loss of all major power stations can be overcome.
With precision munitions, such as cruise missiles, a few power stations providing the power source concentrated into a few discreet locations doesn’t help.
In a modern war, the only thing that works is self-sufficiency, such that mains power loss may have a temporary effect. Back-up generation capability onsite is how every hospital works, but many already have CHP to have higher efficiency and lower costs, i.e. the most economic power and heat generation capability.
Importing oil/gas/coal would all be risky. Depending on those imports would be risky, very risky.
What we should be doing is working on a grid network that is separated out into cells, such that, like terrorist cells, can work independently with no outside connection, such that if one cell is destroyed, that the rest of the network is unaffected.
This is another reason why I am amazed at the number of people who complain about.
1) Renewables
2) Grid upgrades
3) Distributed power generation.
If we are going to have a grid suitable for a 21st or 22nd century war, we need to be a lot smarter than we have been in the past and recognise the new risks that we are facing.
Would 10 or 20 or 50 nuclear power plants suffice?…….not in a million years.
Remember, for an attacker to succeed they only have to get it right once, and the fewer power sources that you have, e.g. 10, means they would only have to be right 10x; 50 power sources 50x; 10,000,000 power sources gets to be pretty resilient.
With certain risks, LCOE isn’t the only factor when you are designing a power grid. Yes an economist, who may promote economic efficiency, isn’t the only voice to listen to, but it is actually very fortunate that PV Solar (the most economic renewable power source) on every house and factory, with significant over-capacity during the summer would definitely help.
Again, you can completely ignore climate change, it’s just another issue, dealing with war risks alone would lead you down the same path. I really don’t understand why people get so fixated with climate change, where if you sort out other important risks, you automatically deal with climate change anyway, so why all the brouhaha about the climate or the current push back where people are feeling alienated by renewables because of climate activists?
The only personal solution is an off-grid setup that is topped up by the grid, or a dual system that can work as a hybrid system, i.e. work as off-grid or grid tied.
Wake up everybody, the world is changing, and we need to be smarter!!!
There are significant reasons other than climate change that justifies the installation of renewables, and it could be a matter of life and death, far more immediate than climate change in 50 or 100 years time.
Greta Thunberg is still just like a child, with a very limited issue that she is obsessing over. It’s not the only important issue that we have to deal with.
What we should be doing is designing a resilient grid for all eventualities. If someone can’t do the risk analysis at a national level, then I can understand why someone may be against renewable power sources, even though such a position is completely illogical taking certain risks into consideration.
This involves no physics of any significance, just scenario analysis, and knowing of what current munitions are capable. SWOT analysis – Strengths, Weaknesses, Opportunities, Threats, may not be in physics or any other academic subject, but is a really useful tool when looking at risks, for every aspect of business or even life.

From the article, it seems that Kathryn herself has probably exacerbated the disaster that will befall the conservative party at the next election.
Feeding anti-renewables and anti-EV misinformation to receptive conservative ministers has resulted in them pushing back the 2030 ban on fossil fuel car sales. However, not only was the 2030 date sufficiently in the future that most red wall 2019 conservative voters won’t be voting on that as a basis, but also, there is large majority UK support for net zero and action on climate change.
Specifically, in a March 2024 YouGov survey, between 40 and 50% of those who voted Leave in 2016 believe UK are worried about climate change and believe politicians in general and the government specifically should be doing more on climate change. See https://d3nkl3psvxxpe9.cloudfront.net/documents/WWF_Environment_240305_W.pdf
From such polling, the Labour party will surely be turning the government backtracking on climate change into a successful election issue.
” However, not only was the 2030 date sufficiently in the future that most red wall 2019 conservative voters won’t be voting on that as a basis, but also, there is large majority UK support for net zero and action on climate change.”
Why do members of the Climate Cult think they are in the majority? Amongst academics and the Blob, Yes, but these are all taxpayer-funded people with nice secure inflation proof pensions. For the rest of us, we have a more commonsense attitude that we support things that make economic sense but we don’t support attacks on our freedoms and standard of living by those of the I’m alright, Jack brigade. Let’s get things straight: there is no science that says we are heading for climate disaster – that is just a political creed. The only clear thing is that CO2 concentrations are increasing, and the impact of that is uncertain. IF global temperatures increase, there are many parts of the world which would welcome that. However, just assume that climate change is on the way because of CO2 concentrations, do you really think that the UK (even with western Europe) can halt any rise in global CO2 concentrations? There is an old Chinese proverb that says he who p*sses into the wind gets what he deserves. The trouble is a mentally disturbed minority are going to visit the repercussions on the innocent and trusting.
And, by the way, 2030 is just around the corner. If Govt were really concerned about living standards and levels of emissions, it would have a population policy and halt immigration. But no. They just bring in millions more and try to impose cuts in living standards. I really can see bloody times ahead.
“Why do members of the Climate Cult think they are in the majority? ”
Purely because that is what all the recent opinion polling is saying – both in the UK and worldwide. So it is an evidence based opinion.
“There is no science that says we are heading for climate disaster”
I beg to differ. The ocean heat content figures show conclusively that the earth system is steadily accumulating heat. 90% of it ends up in the oceans, which means it is easy to measure there because there is not that much noise to introduce random fluctuations on top. See the blue and red chart near the top of https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content. It is very clear that ocean heat content only really started taking off from the 1960s when CO2 emissions really got going. And it has been steadily increasing ever since.
We could argue about the other 10% – that goes into the land surface and atmosphere, but if the seas are clearly warming up, then everything else must be too.
“do you really think that the UK (even with western Europe) can halt any rise in global CO2 concentrations? ”
UK is similarly sized to each of the 26 Chinese provinces, both in terms of population (UK 1%, China 20%) and in terms of average emissions. Between the 27 of us we clearly can and should make a big difference.
Further, UK is responsible for 4.6% of cumulative historical emissions, which means 4.6% of the 1.2 or 1.5 or 1.6 degrees of warming so far (whatever it is this month). Well out of kilter with our population. That means we have a responsibility to do a lot more per capita that China, which is responsible for around 14%.
And China is doing huge things – it installed 292 GW of wind and solar in 2023 – as much as the rest of the world put together (for the second time – first time was in 2020) .
We installed <5 GW of wind and solar in 2023. Pro rata Chinese actions to suit UK scale. On population we should have installed 5% or 15 GW. On historical CO2 cumulative emissions we should be installing 80 GW or so. On current emissions it would be 10 GW. On GDP ($18tr vs $3tr), it would be 50 GW.
Take your pick. On any objective analysis of of China vs UK, who is pulling its weight at present, and who is not, UK is falling short.
I would suggest that it is the current UK government which is ****ing in the wind, but the Chinese, full of wise sayings, is stepping up to the mark.
Any analysis by population increases is futile. The fact is that it is the energy-profligate western lifestyle which has caused the problems with warming (USA pop 320m 25%, China pop 1.4bn 14%). The OECD has caused over half the warming so far, with fewer people than China. Growing population anywhere, and particularly in the developing worlds, is irrelevant to global warming – where the largest high per capita emitter is the USA with twice the per capita emissions of China.
谢谢
Hi Kathryn….Happy 8th and thanks for another great posting.
Trust you will forgive my following somewhat slightly off topic response.
A celebration with a sincere message.
I spent 40 years of my life devoted to UK power networks CEGB/Nat.Grid.
Worked too hard at the expense of lifestyle & family as you do, in many instances.
However work is never hard when you enjoy every minute.
The final few months were horrible but retirement day 2021 was brutal, like falling off a cliff.
I did attend a few retiree gatherings which didn’t do it for me. My socially awkward outlook was exacerbated with the loss of my wife in 2018.
I stumbled on Grid Watch, a crowded screen full of information & a quirky dash board layout.
I love the dials, instantly recognisable as an engineer’s practical approach.
At some point I clicked on Watt-Logic, a tiny text prompt in one corner of their busy screen.
The rest is history, a great forum that takes me back to those vanished years.
The content goes without saying the consistently, splendid easy to read layout IMO engineer inspired.
My personal library as an interested observer of all things associated with UK energy security.
I go forward these days, & yes I’ve had to reach out to family, millennial’s, professionals, you name it.
Watt-Logic has allowed me to do this with confidence raising the profile of engineers at every oportunity.
A Watt-Logic email dropping in my in box always means a good day.
Sure there are many retired engineers out there who feel the same.
IMO there is also social dimension to Watt-Logic which works for me…….thanks Kathryn, thanks Watt-Logic & all contributors.

“Michael – you do know that Kathryn’s degree was in Physics? I suspect she has a far greater knowledge of physics that most of the staff at carbonbrief.
Sadly, Katherine shows very poor knowledge of the Physics related to climate change.
“Of course you are inclined to think that with your career at NPL you are one of the only ones who understands these arcane matters. There are large catalogues of failed climate model predictions. A few from James Hansen include an ice free Arctic, parts of New York city under water, and far greater temperature increases than even GISTEMP shows – all by now or earlier. Serious climate scientists have been wrestling with the problem that many models run too hot. Perhaps you should look at that work rather than the propaganda?”
The thing about the models is that the very simplest models agree pretty well with the gigantic super-complex models. And there are no models which say there is nothing to worry about. And the experimental data and its trends are extremely concerning. James Hansen is right to warn of an ice free Arctic – we are well on our way to ice-free arctic summers. Climate change is with us, and until we stop emitting carbon dioxide, the Earth will keep warming. And we do not know where the climate tipping points will be reached, but we do know they exist. The best climate models give us some idea of where these tipping points might occur. But overall, the models show that Earth’s climate is extraordinarily sensitive to small perturbations. And the radiative forcing from CO2 is not minor. And the science of climate change is opposite of propaganda. It’s all completely open to scrutiny and uses really simple basic physics.
“I hope you have accounted for the minerals mined to make your Tesla in your evaluation of its environmental impact. I bet you don;t keep it until the 80,000 mile breakeven.”
Not a Tesla, and by chance the car is within 100 miles of 80,000 as I write. But by any reasonable analysis, its carbon debt was paid off more than 40,000 miles ago.

Thank you Kathryn for the many insightful words over the 8 years. I am always astonished by the breadth and depth of your coverage as well as the technical content. I hope that despite your influencer status, and surely business demand, you continue to find time to write the blog and keep the rest of us informed. Thank you for your help with SSS Clutches too!
Here is to the next 8 years – who wants to predict/guess where we will be then?
Thanks James! I definitely don’t want to be making any predictions, other than to hazard that the first until of Hinkley might have opened!
I think this blog has attracted some odd characters. Not content with jabbering on about net zero, as if it were a proven fact, we now have to bring in preparation for world wars in this and the next century. It really sounds as if the character in question actually relishes the prospect! If you are going to plan for world wars I think the availability of energy coming into your radioactive house without a roof and without inhabitants is really of no consequence whatsoever.
JH said “Not content with jabbering on about net zero, as if it were a proven fact”.
It is difficult to see how you can have a “proven fact” right now about something in the future, so I don’t get your criticism here. A 2035 net zero grid is the current UK plan of record, though it will only become a fact if the necessary actions are taken to make it happen. But if it doesn’t happen in 2035, it will surely happen not that long after 2035.
You have something right! I should have said “damaging climate change” rather than net zero which is just the policy. And then you walk away with egg on your face anyway when you write “It is difficult to see how you can have a “proven fact” right now about something in the future”. So damaging climate change is not a fact, just an opinion, which is NOT backed up by scientific enquiry. Your opinion is based on one strand of thinking – and not a very good strand at that. I was probably looking at climate models when you were in nappies and the deficiencies then were alarming, and now its even worse as the 20 or so models around the world are not independent at all but feed off each other. As for net zero as a policy, who voted on that? it was just something that May (of shoe fetish fame) decided on. No CBA, no nothing. Ludicrous – like most of what happens in the UK today.
Yes, you can ignore climate change if you so wish, and can say, yes, we’ll adapt to any temperature change (if it occurs), which as the earth and other planets go through cycles and the earth’s orbit changes we’d have to adapt to anyway as we cannot change the orbits of the planets, which also causes climate change,
More air-conditioning in summer, with heat waves whenever they occur, which would be helped with more Solar PV installations. So why not install more Solar PV now anyway?
or you can insist that it doesn’t occur, which is OK as a hypothesis based on certain data, and do nothing.
BUT,
We can’t keep pumping CO2 into the atmosphere indefinitely because it starts to get uncomfortable and it gets harder to breathe because the rate of CO2 exchange from haemoglobin in the blood to the atmosphere in the lungs is reduced, so the O2 saturation level of your blood drops. It gets harder to breathe………hypoxia if the CO2 level gets high enough.
There’s no problem at the moment, but if we keep burning every bit of carbon stored up we will get to that point where there are additional costs due to inaction. If you want to discuss opportunities, then now is the time as technology becomes available and economic to do so, is to reduce the CO2 we’re pumping out, as not only do we get better energy security, we stop asphyxiating ourselves.
Do you want your grand children/great grand children etc etc to be able to breathe……..easily?
You could say I don’t care, survival of the fittest and all that, weed out the weaklings………Scrooge………surplus population wasn’t it?
The CO2 levels were much higher previously, but has been captured from the atmosphere. Do you believe that the human race can adapt to the changing CO2 concentration fast enough to avoid all suffering?
After all, much of the planet has been deforested.
How do you look at it?
You do know that the CO2 level is increasing don’t you, which is an irrefutable fact.
Potentially damaging atmospheric changes are starting to occur already, and again we might be able to adapt to the climate, but just the effect of CO2 on its own would mean that we would have to start electrolyzing water or increase the liquifaction of air to meet the higher demand for O2 cylinders or have CO2 scrubbers and breathing suits or atmospherically controlled rooms for babies/elderly/obese etc etc.
What future do you imagine?
The term for high CO2 in the bloodstream is hypercapnia, and actually affects you before you get to hypoxia.
You can then look up carbon dioxide narcosis, if you really want to get technical, where people with COPD suffer from problems already with being unable to reduce their blood CO2 levels.
Yes, more and more people would be affected as the CO2 level rises, increasing healthcare costs, as if they aren’t high enough already.
There are consequences of inaction.
5% of the US population has COPD, and of course you don’t know how many people are on the edge of diagnosis.
5% population = 15 million people already with problems, how many more do you want to be included as the CO2 level rises?
It affects older people already with bad diet/smoking, but it will start to affect younger and younger people as the level of CO2 rises. Smokers/vapers should all be worried, they’ll be the ones with problems first, where even now there are problems for some people who do too much smoking/vaping, although the CO2 level is only rising at 2.55ppm per year, so most people now won’t be affected.
This is 100x faster than any natural change that has ever occurred before.
At high CO2 levels you get headaches, which if you have ever sat too long in a chair you will know what I mean, like driving for too long, so the higher the CO2 level, the less time you would be able to spend sitting down, which would be difficult for people with mobility problems, and you can increase O2 levels, but if the CO2 isn’t being exchanged, you can increase the O2 all you like, it won’t release the CO2, which is dependent on the CO2 concentration gradient.
One of the good articles on global warming that is well balanced is https://www.climate.gov/news-features/understanding-climate/climate-change-incoming-sunlight
And look at the graph of the Yearly Temperatures in the Northern Hemisphere 30o – 60o N
The temperature has risen by 1.5 degrees since the minimum in around 1850, but we are getting to around the previous peak that occurred in the year 1000
Yes it goes through the Milankovitch cycles about the effect of the planet’s changing orbit, and how much of the current 1.5 degrees temperature rise is due to CO2 emissions is debatable, but it still leaves a problem with CO2 itself, no matter what your view of climate change is. The temperature has risen by 1.5 degrees, again that isn’t debatable, it is a fact.
Being self-sufficient for everything is actually very helpful for the economy and security, unless you have developed teleportation and have got secure mining/farms elsewhere.
Of course if someone has made the assumption that the 1.5 degree rise is all due to CO2 emissions, then they could have the wrong climate models.
It is interesting that taking personal responsibility for ones own security of energy/power that would be essential in certain circumstances and would be financially rewarding/beneficial at all times, no matter what the circumstances, is seen as a bad thing. Controlling for risks, like any contingency planning, is that it isn’t essential or needed until that risk crystalises into reality. If something can be built that doesn’t cost any more than alternatives, but gives extra coverage of various risks, why wouldn’t you do it? To not do it would be negligent if you were aware of the risks and could afford to do it.
My last car accident was 17 years ago, car written off, caused by another driver, head-on collision. I’m a good driver, never caused a claim due to my fault. Are you sure everyone else will act exactly as you expect/want them to, according to rules/regulations/laws?
It may not be a war of massive forces but one of guerrila sabotage, knocking out key infrastructure, where exposed powerlines can be destroyed by deniable forces, sleeper cells, drone warfare is very popular these days.
I prefer to not put my head in the sand with any risks. It doesn’t have to be nuclear war, there are many scenarios without nuclear bombs that could be problematic.
Do you by any chance work for the Health and Safety Executive? Your diatribes bear all the hallmarks of fear. FDR was right: “The only Thing We Have to Fear Is Fear Itself”
Isn’t that what you would say when all preparations have been made and every contingency is in place?
Are we?
Let me try another tack. Ever heard of the concept of opportunity cost? Every action has a cost – the lost opportunity of alternative actions. There is just no point in planning for and acting upon a plan which in all likelihood would never be needed. You have wasted your time and resources. Whether you do this in YOUR time is up to you, but don’t presume to waste the resources of everybody else.
Well I’m not sure of the extent to which Tim has advanced my knowledge, as I was reasonably clued up anyway, but I certainly have to look at the possibility of a heat pump over the next 12 months, as our condensing boiler has stopped condensing (and at only 24 years old too – disgraceful). We have just insulated our house externally so such a move would likely not result in having to replace all the radiators too, with the possible exception of one of 3 in the kitchen.
The issue with heat pumps is having to pay through the nose for electricity when gas prices are high. If there were options for building heating phase change thermal storage, this would allow most of the heat pump use to take place at off-peak power rates, such as the Intelligent Octopus Go rate of 7.5p/kWh, guaranteed for 6 hours out of every 24 hours (but flexible). My brother recently pointed out that a Tesla Powerwall, or suchlike, provides a more capital intensive option for cheap heat pump operation – you charge with the cheap power then feed it into the heat pump continually over the 24 hours. If one is going that far, maybe it would make sense to look at solar PV panels too. So Tim is at least right in my case.
Whether it is all a good idea or not depends on working through the numbers, of course, to calculate the pay back. If it is not cost effective right now, it is quite likely to become so, depending on how fast the cost of heat pumps, domestic electricity storage and solar panels come down.
The opportunity cost isn’t that high to work through the figures.
In terms of time savings, what would make the most difference to many of us is not to feel obliged to debunk all the anti-renewables, climate denier and anti-EV misinformation put out which could readily be fact checked first by the perpetrators. The 4 or 5 per month anti-EV Daily Telegraph articles particularly come to mind, with their inevitable cherry picking and lack of objectivity.
The majority of countries, and the majority of people in them, when polled, are fully supportive of actions to reduce CO2. So such actions were very clearly going to happen anyway, irrespective of a very vocal views of a small minority. The most obvious case is that solar PV installations are ramping up year after year and now represent the largest source of new generation. This is clearly going to become more marked each year – even the UK has a target of 70 GW of solar PV installed by 2035. The time saving all round would come from the anti-renewables crowd no longer continually insisting that the rest of us do not know that the sun does not shine at night – a fact which is surely known by 99.999% of the population since they were 3 years old, maybe?
I don’t presume anything. I just thought that those people who are installing Solar PV, would be interested, and represents a good reason to install a Tesla Powerwall, or an equivalent capability, but so many people just don’t like renewable technologies for some weird reason.
Grid-tying has its limitations, because if the grid shuts down, on the earlier inverters, they had to shut down as well, which is a bit of a waste if there is plenty of battery power and sunshine.
If someone is going to the bother, and considerable expense, and there are many people who are doing so, both families and companies/local authorities who have to do resilience planning for disasters etc, might be able to use the information I gave for their own benefit, and might encourage Kathryn to think outside of her box that she’s created for herself.
I can understand as you have so clearly stated that you wouldn’t. No problem, your choice, others might though, their choice. It’s a free country.
Would you say that every factory and individual home where people have installed solar panels with batteries have made the wrong choice, where they have decided to reduce their electricity bills?
Are you criticising all Powerwall customers?
The whole point of my argument is that there are certain technologies that already exist that can make the system national disaster proof throughout a significant part of the year, and it would only be the depths of winter where load shedding would be essential in any such emergency.
For a company with significant profits, or a family with high income, sometimes they value risk reduction for a few hundred or even a few thousand pounds far more than any possible lost opportunity if they could throw thousands/tens of thousands at other things just for enjoyment.
How much money does the government waste? How much do you spend on unnecessaries, non-essential items? A flutter on the geegees, drink, vaping, running a bigger car or newer than absolutely necessary, oh I have to go to Las Vegas?
Other people value in-depth risk analysis. Aren’t you presuming that everyone else has the same view as you?
I just wonder what the sales are like for the Tesla Powerwall and equivalent products.
Some interesting comments here.
I am not sure that the National grid should be financing the connections to the grid themselves. Certainly there is a case to be made for the supergrid, though, if energy storage was included then this might ameliorate the requirements.
The idea of smart-grids that can connect and disconnect at will is dubious in some ways – as it allows these small grids to connect when everyone else is short of power.
However if SMART grids are self-sufficient then they could sell excess power – but that begs the question of how so to do. I think it would require small scale generation and storage – but there is little evidence of affordable long duration storage being considered and small scale (thermal?) generation being researched.
I recently saw a post of the Engineer that referred to https://windgod.fluke.org.uk/?power=2000&storage=279000 . It demonstrates how much storage might be required for the country as a whole (so each SMART grid could be included) based around diurnal generation (so such generation would require its own short term storage) for the year 2019
