The head of markets at the National Grid Electricity System Operator has told Sky News that its new energy saving scheme “is likely how we’re all going to operate in the future.”
The new Demand Flexibility Service, which allows consumers to volunteer to use less electricity at times of peak demand to help avoid blackouts, has been activated twice this winter.
The Grid’s head of markets, Claire Dykta, described it as an effective “insurance policy” for the coming months, but also a demonstration of how the system could adapt as it is increasingly powered by clean, renewable energy, which is more intermittent than the polluting fossil fuels it is replacing.
She said: “Demand flexibility is going to be a really important component of our energy supply mix going forward and it will grow and grow as something that we all get used to.
“Once we’ve got electric cars and we don’t have gas boilers anymore, we’re going to be using energy very differently to how we use it today. Consumers being able to shift their demand is likely how we’re all going to operate in the future.”
Retired bereavement counsellor, Wendy Hall, 65, is from one of the around a million UK households that have signed up to take part in the Demand Flexibility Service.

This time, she was asked by her energy supplier to save at least 20% of her regular usage over one-and-a-half hours.
When we arrived at her small single-story home in Chesterfield all the lights and appliances were off. Wendy was wrapped in her dressing gown for warmth, and was relying on the wood-burning fire in the living room to heat that part of the house.

She planned to eat and wash her clothes later in the evening, to avoid using large appliances that typically use lots of electricity.
During the energy reduction period, she had her phone and Wi-Fi on, and kept a battery-powered lantern nearby to light her path as she moved around her home in the darkness.

National Grid: Cash to reduce energy
Avoiding blackouts for vulnerable who need electricity
So far, the most Wendy has managed to save in one session is £3.66. Although, for her, this isn’t the main motivator.
“Primarily, it’s about avoiding blackouts for people who need the electricity, such as families with young children, elderly or disabled people. If I can just do a little bit and it helps them then that’s everything for me,” Wendy said.
“I’m not worried about the money, it’s not about that. Thinking about the war days, they dug for England, they made do and mended and if just switching the power off for one hour is a help to other people, I’m happy to do it.”
The National Grid emphasised that advances in smart appliances and technologies will ultimately make it much easier for people to consume electricity more flexibly, helping keep bills down at the same time as reducing demand at peak times.
Ms Dykta said: “I think one thing we should be really clear about is that when we talk about this Demand Flexibility Service and what it means, it’s about shifting your energy intensive appliances so your tumble dryer or your washing machine or your electric oven – and using those at different times.
“It’s not about switching everything off and sitting in the dark.
“Great Britain is on a journey to a high renewables green system. We’re further along than a lot of others, so demand flexibility is a step on that journey.”

‘Smart’ consumers playing active part in system
But are the majority of British consumers ready to make this shift in their energy consumption habits?
E.ON chief executive Michael Lewis believes they are.
He told Sky News that “smart” consumers becoming an active part of the energy system is a critical part of its future.
“I think people are ready. They fully understand that we need to get off fossil fuels.
“We need to get to net zero and we need to get ourselves off these volatile international prices. And I think what Putin’s invasion of Ukraine has shown is how reliant we are on unstable political regimes.
“They know we need to take responsibility for our energy system and that means every individual taking responsibility for how we consume energy.”
But he warned that ditching fossil fuels will require a “huge national investment and a huge national effort”.
“Bear in mind we have to massively expand electricity generation, because not only are we replacing old fossil fuel generation, we’re also replacing all of the petroleum that goes into cars with electricity, and all of the gas that goes into heating with electricity.
“So we need much more renewable energy generation upstream and that’s both large scale generation like offshore wind, but also more embedded generation, like solar panels on every roof, and more electric vehicle chargers in homes and businesses.”

‘We save £10 a day on energy scheme’
As well as increasing efforts to make homes more energy efficient, he said: “We have to look at storage.
“Batteries of course are great for short-term storage and as the electric vehicle fleet increases there’ll be more and more battery capacity embedded in the system, but we also need a long-term solution for seasonal storage.
“And that’s probably going to be hydrogen and we have to ramp up green hydrogen production to create that storage for when the wind isn’t blowing and when the sun isn’t shining.”
As part of its promise to decarbonise power generation in this country by 2035, the government has ambitious plans to ramp up battery storage and green hydrogen production, as well as increase wind power fivefold by the end of the decade.
But some industry experts worry that too much faith is being placed in technologies that, while rapidly advancing, are not yet at the necessary scale and affordability.
Heading for supply crisis in mid 2020s
Energy analyst from the Watt Logic consultancy, Kathryn Porter, says that the system has held up relatively well this winter, in part because warmer weather reduced the demand for gas, which provided just under 40% of our electricity generation last year.
But she is worried about what is to come, particularly about reliance on foreign electricity imports from European partners, especially France.
She said: “We’re running into a supply crisis in the middle of this decade.
“The reality is that this is the second time in five years that the French have taken large parts of their fleet offline for systemic problems, and so thinking that we can rely on old French reactors to get us out of trouble, I think is a little bit optimistic.
“We have legislation in place that requires all the coal power stations to close by October 2024.
“There are also two of our remaining nuclear power stations scheduled for closure in March 2024.
“So we have a situation where the winter after next, all of the spare capacity that we currently have… that will have gone.
“So we need to replace that. And the only realistic way of doing that is to build gas power stations. Now two years isn’t really long enough to do that.”
A government spokesperson told Sky News: “Putin’s illegal invasion of Ukraine has shown it is now more important than ever that we boost the UK’s homegrown energy supply to strengthen domestic resilience and energy security now and into the future.”
They added that the British Energy Security Strategy will “supercharge” renewable energy and nuclear capacity, as well as support North Sea oil and gas.
Billions have also been invested up until 2028 to make buildings more energy efficient, they said.
The Ministry of Defence (MoD) has announced it will buy £118m worth of air defence missile systems for the British Army.
But will this new purchase protect an increasingly vulnerable UK from attack, and why now?
For more than 50 years, the British Army relied on the Rapier air defence missile system to protect deployed forces.
In 2021, that system was replaced by Sky Sabre.

The new system is mobile, ground-based, and designed to counter various aerial threats, including fighter aircraft, attack helicopters, drones, and guided munitions.
It’s known for its speed, accuracy, and ability to integrate with other military assets, including those of the Royal Navy and Royal Air Force (and NATO).
What is the Land Ceptor missile, and why do we need more of them?
Sky Sabre includes radar, command, and control capability and – most importantly – a missile to intercept incoming threats.
The Land Ceptor missile weighs around 100kg, has a 10kg warhead, and can intercept threats out to around 15 miles (25km), making it around three times more effective than the Rapier system it replaced.

When the MoD made the decision to replace the Rapier system, the global threat environment was very different to that experienced today.
Since the end of the Cold War, the UK has been involved in expeditionary warfare – wars of choice – and generally against less capable adversaries.
So, although the Land Ceptor missile is very capable, defence planning assumptions (DPAs) were that they would not need to be used in a serious way, commensurate with the threat.
However, as the Russian invasion of Ukraine has demonstrated (as has the series of Iranian attacks on Israel), significantly larger stockpiles are required against a more capable enemy.

Is the UK vulnerable to missile attack?
In short, yes. Although the Land Ceptor missile does provide an excellent point-defence capability, it is not an effective counter to ballistic or hypersonic missiles – the Sea Viper mounted on Royal Navy Type 45 Destroyers using the Aster 30 missile has that capability.
In the Cold War, the UK had Bloodhound missiles deployed around the UK to provide a missile defence capability, but as the perceived risks to the UK abated following the collapse of the Soviet Union, UK missile defence fell down the priorities for the MoD.
Although the radar based at RAF Fylingdales forms part of the Ballistic Missile Early Warning System (BMEWS), and can detect incoming threats, the UK no longer has an effective interceptor to protect critical national infrastructure.
Instead, the UK relies on the layered defences of European allies to act as a deterrence against attack.
In the near term, this timely order for Land Ceptor missiles doubles the British Army’s tactical capability.
However, as the conflicts in Ukraine and the Middle East have demonstrated, ballistic (and increasingly hypersonic) missiles are being produced in increasing quantity – and quality.
Without significant (and rapid) investment, this critical gap in national military capability leaves the UK vulnerable to attack.
A newly-discovered dinosaur with an “eye-catching sail” along its back and tail is to be named after record-breaking yachtswoman Dame Ellen MacArthur.
Istiorachis macaruthurae was identified and named by Jeremy Lockwood, a PhD student at the University of Portsmouth and the Natural History Museum.
Istiorachis means “sail spine” and macaruthurae is taken from the surname of Dame Ellen, who became famous for setting a record for the fastest solo non-stop round-the-world voyage in 2005.
Dame Ellen is from the Isle of Wight, where the creature’s fossils were found.

Before Dr Lockwood analysed them, the fossils, which date back 125 million years, were thought to be from one of the two known iguanodontian dinosaur species from the island.
“But this one had particularly long neural spines, which was very unusual,” he said.
Writing in the scientific journal Papers in Palaeontology, Dr Lockwood said his study showed the dino would have probably had a pronounced sail-like structure along its back.
The exact purpose of such features “has long been debated, with theories ranging from body heat regulation to fat storage”.
In this case, researchers think it was most likely to be for “visual signalling, possibly as part of a sexual display”.

For the study, the researchers compared the fossilised bones with a database of similar dinosaur backbones which allowed them to see how these sail-like formations had evolved.
Dr Lockwood said his team showed Istiorachis’s spines “weren’t just tall, they were more exaggerated than is usual in Iguanodon-like dinosaurs, which is exactly the kind of trait you’d expect to evolve through sexual selection”.
Professor Susannah Maidment, of the Natural History Museum, said: “Jeremy’s careful study of fossils that have been in museum collections for several years has brought to life the iguandontian dinosaurs of the Isle of Wight.
“His work highlights the importance of collections like those at [Isle Of Wight museum] Dinosaur Isle, where fossil specimens are preserved in perpetuity and can be studied and revised in the light of new data and new ideas about evolution.
“Over the past five years, Jeremy has single-handedly quadrupled the known diversity of the smaller iguanodontians on the Isle of Wight, and Istiorachis demonstrates we still have much to learn about Early Cretaceous ecosystems in the UK.”
On the 10th anniversary of the Shoreham air disaster, the families of some of those killed have criticised the regulator for what they describe as a “shocking” ongoing attitude towards safety.
Most of them weren’t even watching the aerobatic display overhead when they were engulfed in a fireball that swept down the dual carriageway.

Jacob Schilt, 23, and his friend Matthew Grimstone, also 23, were driving to play in a match for their football team, Worthing United FC.
Both sets of parents are deeply angry that their beloved sons have lost their lives in this way.
“It obviously changed our lives forever, and it’s a huge reminder every 22nd of August, because it’s such a public anniversary. It’s destroyed our lives really,” his mum, Caroline Shilt, said.
“It was catastrophic for all of us,” Jacob’s father, Bob, added.

‘They had no protection’
Sue and Phil Grimstone argue that the regulator, the Civil Aviation Authority (CAA), has not been held accountable for allowing the airshow to take place where it did.
“At Shoreham, the permission given by the CAA did not allow displaying aircraft to perform over paying spectators or their parked cars,” they said.
“But aircraft were permitted to fly aerobatics directly over the A27, which was in the display area, a known busy road.
“This was about ignoring the safety of people travelling on a major road in favour of having an air show. They had no protection.”

A series of catastrophic errors
The crash happened while the experienced pilot, Andy Hill, a former RAF instructor, was attempting to fly a loop in a 1950s Hawker Hunter jet.
But he made a series of catastrophic errors. His speed as the plane pitched up into the manoeuvre was far too slow, and therefore, he failed to get enough height to be able to pull out of the dive safely. The jet needed to be at least 1,500ft higher.
Mr Hill survived the crash but says he does not remember what happened, and a jury at the Old Bailey found him not guilty of gross negligence manslaughter in 2019.

When the inquest finally concluded in 2022, the coroner ruled the men had been unlawfully killed because of a series of “gross errors” committed by the pilot.
The rules around air shows have been tightened up since the crash, with stricter risk assessments, minimum height requirements, crowd protection distances, and checks on pilots.
But Jacob and Matt’s families believe the CAA still isn’t doing enough to protect people using roads near airshows, or other bystanders not attending the events themselves.

The families recently raised concerns about the Duxford airshow in a meeting with the CAA.
While aircraft are no longer allowed to fly aerobatics over the M11, they do so nearby – and can fly over the road at 200ft to reconfigure and return. If the M11 has queuing traffic in the area, the display must be stopped or curtailed.
The Grimstones believe this demonstrates accepting “an element of risk” and are frustrated that the CAA only commissioned an independent review looking at congested roads and third-party protection earlier this year.
“We feel the CAA are still dragging their feet when it comes to the safety of third parties on major roads directly near an air show,” they said.
The family have complained about the CAA to the parliamentary ombudsman.

‘There are still question marks’
Some experts also believe the CAA has questions to answer about a previous incident involving Mr Hill, after organisers of the 2014 Southport Airshow brought his display to an emergency stop because he had flown too close to the crowd, and beneath the minimum height for his display.
In its investigation into the Shoreham disaster, the Air Accident Investigation Branch (AAIB) later found that while the CAA inspector present had an informal discussion with the pilot, no further action was taken, and the incident was not reported to the AAIB.
Retired pilot Steve Colman has spent many years looking into what happened at Shoreham, and he believes the CAA failed to fulfil their statutory obligation to fully investigate and report the incident at Southport.
“You have to ask the question – if the Southport incident had been investigated, then was Shoreham more likely or less likely to have occurred?” he said. “I think there can only be one answer – it’s less likely to have occurred.”
Tim Loughton, who was the MP for Shoreham at the time, believes a balance must be struck.
“We don’t want to regulate these events out of existence completely. A lot of the smaller air shows no longer happened because they couldn’t comply with the new regulations […], but certainly there are still question marks over the way the CAA conducted and continues to conduct itself. I would welcome more parliamentary scrutiny.”

Rob Bishton, chief executive at the CAA, said: “Our thoughts remain with the families and friends of those affected by the Shoreham Airshow crash.
“Following the crash, several investigations and safety reviews were carried out to help prevent similar incidents in the future. This included an immediate review of airshow safety and a full investigation by the Air Accidents Investigation Branch. All recommendations and safety improvements from these reviews were fully implemented.
“Airshows continue to be subject to rigorous oversight to ensure the highest possible safety standards are maintained.
“At a previous airshow in 2014 the pilot involved in the Shoreham accident was instructed to abort a display by the show’s flying director. This incident was investigated by the UK Civil Aviation Authority and regulatory action was taken.”
Mr Bishton added: “As part of the work to review the safety oversight of airshows following the tragic Shoreham crash, the actions taken by the regulator following such a stop call were enhanced.”
But the families of those killed still believe much more could be done.
