The amount of UK electricity generated from fossil fuels fell 22% year-on-year in 2023 to the lowest level since 1957, Carbon Brief analysis reveals.

The 104 terawatt hours (TWh) generated from fossil fuels in 2023 is the lowest level in 66 years. Back then, Harold Macmillan was the UK prime minister and the Beatles’ John Lennon and Paul McCartney had just met for the first time.

Electricity from fossil fuels has now fallen by two-thirds (199TWh) since peaking in 2008. Within that total, coal has dropped by 115TWh (97%) and gas by 80TWh (45%).

These declines have been caused by the rapid expansion of renewable energy (up six-fold since 2008, some 113TWh) and by lower electricity demand (down 21% since 2008, some 83TWh).

As a result, fossil fuels made up just 33% of UK electricity supplies in 2023 – their lowest ever share – of which gas was 31%, coal just over 1% and oil just below 1%.

Low-carbon sources made up 56% of the total, of which renewables were 43% and nuclear 13%. The remainder is from imports (7%) and other sources (3%), such as waste incineration.

Overall, the electricity generated in the UK in 2023 had the lowest-ever carbon intensity, with an average of 162g of carbon dioxide per kilowatt hour (gCO2/kWh).

This remains a long way from the government’s ambition for 95% low-carbon electricity by 2030 – just seven years from now – and a fully decarbonised grid by 2035.

Fossil falls

Historically, fossil-fuel generation rose steadily as the size of the UK’s economy expanded – and, relatedly, as demand for electricity grew.

The rise in demand for electricity paused during the late 1970s and 1980s, as the country’s economic situation and industrial relations worsened. Yet the upwards march soon resumed.

Electricity demand then started to “decouple” from economic growth in the early 2000s, leading to a peak in 2005. Since then, demand has dropped precipitously, falling from 396TWh in 2008 to 313TWh in 2023, as shown by the dark blue line in the figure below.

This reduction in demand of 83TWh (21%) is equivalent to more than three times the expected output of the Hinkley Point C nuclear power plant, which is currently being built in Somerset.

Demand reductions are the result of a poorly understood combination of more efficient appliances and lighting, high prices driven by expensive gas and changes in the structure of the UK as it shifts to an ever more service-led rather than manufacturing-heavy economy.

(In the medium- to long-term, electricity demand is expected to rise as transport and heating are increasingly electrified using electric vehicles and heat pumps.)

While electricity demand was falling, the UK was also starting to rapidly scale its renewable energy capacity, primarily from wind, but also from solar and bioenergy.

As a result, renewable electricity output climbed six-fold from 23TWh in 2008 to 135TWh in 2023, shown by the red line in the chart below.

The combined impact of falling demand (-83TWh) and rising renewables (+113TWh) has acted as a pincer on electricity generation from fossil fuels, squeezing it from two directions.

Having peaked at 303TWh in 2008, the UK got just 104TWh of electricity from fossil fuels in 2023 – as shown by the steep black line in the figure below – a two-thirds reduction in 15 years. This takes fossil-fuel generation to its lowest level since 1957.

In 1957, the Conservative party’s Harold Macmillan was elected UK prime minister in January following Anthony Eden’s resignation due to ill health.

That same year, the Central Electricity Generating Board was established ‘to keep the lights on’. It was responsible for electricity generation, transmission and bulk sales in England and Wales up until the electricity sector was privatised in the 1990s. 

The world’s first commercial nuclear power station, at Calder Hall in Cumbria, had just opened its second unit, yet fossil fuels still supplied 97% of the UK’s electricity.

Also that year, the Suez canal was reopened, “Sputnik 1” – the first artificial satellite to orbit Earth – was launched by the Soviet Union and the UK government unveiled plans to allow women to join the House of Lords for the first time.

Shifting shares

For most of the past century, fossil fuels generated almost all of the UK’s electricity, as shown by the black line in the figure below. Fossil fuels – predominantly coal – made up 97% of the total in 1957, a figure that had barely changed for decades.

The rise of nuclear power (dark blue line) from the late 1950s onwards – after Calder Hall opened in 1956 – pushed the fossil fuel share downwards.

Yet electricity demand continued to grow and the earliest nuclear reactors were starting to shut down by the early 2000s, with only Sizewell B in Suffolk, in 1995, having replaced them.

With renewables still in their infancy, this meant that, in 2008, the UK was still getting 76% of its electricity from fossil fuels. Of this, 45% was from gas and 30% from coal.

Since then, fossil fuels’ share has dropped to a record-low 33% in 2023, being overtaken by renewables in the process (red line).

Renewables’ share reached a record high of 43% in 2023, with nuclear (13%, light blue line), imports (7%) and other sources (3%) making up the remainder.

The total share from low-carbon sources – renewables and nuclear – was 56% in 2023. This was down one point from the record 57% share in 2022, as a result of a drop in nuclear output.

The current government’s ambition is to get 95% of the country’s electricity from low-carbon sources by 2030, which would mean an increase of 39 percentage points in seven years.

To date, the fastest rate of increase has been 25 percentage points in seven years, achieved between 2010 (23% low-carbon) and 2017 (48%).

The aim is then to fully decarbonise the grid by 2035. The opposition Labour Party’s aim is even more ambitious, hoping to fully decarbonise the electricity grid already by 2030. This would be a 44 percentage point increase in seven years.

Renewable rise

The rise of renewables since 2008 has been nearly as steep as the fall for fossil fuels, as shown by the red line in the figure below.

Notably, however, since reaching 134TWh in 2020, renewables have effectively stood still, with output of 135TWh in 2023, matching the record 135TWh set in 2022.

This reflects the balance between continued increases in wind and solar capacity, variations in average weather conditions and reduced output in the past two years from bioenergy.

The 135TWh of renewable electricity in 2023 was made up of:

  • 82TWh from wind (up 2TWh year-on-year, a 2% increase);
  • 35TWh from bioenergy (down 5TWh and 13% from 2021 levels);
  • 14TWh from solar (up 2% year-on-year);
  • 5TWh from hydro (down 1TWh year-on-year, a 9% drop).

At the same time, coal has nearly disappeared from the UK electricity system, falling from 119TWh in 2008 to 4TWh in 2023 (down 115TWh, 97%), shown by the black line below.

Gas, meanwhile, is now down to levels rarely seen since the mid-1990s (grey line), falling from 178TWh in 2008 to just 98TWh in 2023 (down 80TWh, 45%).

Nuclear also continues to decline, reaching 41TWh in 2023, a 7TWh reduction year-on-year (15%) from already low levels, after Hinkley Point B in Somerset closed down and the remaining five stations were temporarily offline for planned maintenance outages.

Capacity for both onshore and offshore wind projects rose in 2023, by 0.6GW and 1.1GW, respectively.

Average wind speeds in the first 11 months of 2023 were well below the long-term average however, according to government figures, whereas 2022 had only been marginally below average. This muted overall generation growth over the last year somewhat. 

A windy December helped boost overall generation figures for the year, with a new wind generation provisionally set on 21 December according to National Grid ESO. Wind generation hit 21.8GW between 8:00 and 8:30 on 21 December, providing 56% of the generation mix.

Notably, only one offshore windfarm was completed in 2023 – the 1GW Seagreen development off the east coast of Scotland – whereas three projects totalling 3GW were commissioned in 2022.

In October 2023, Dogger Bank off the coast of Yorkshire sent power to the national grid for the first time. It will be the world’s largest offshore windfarm, at 3.6GW, when it is completed in 2026.

Nevertheless, the government’s ambition for 50GW of offshore wind by 2030 is in doubt after the latest auction for new renewable capacity failed to secure any additional projects.

For bioenergy, the 35TWh in 2023 was similar to the level delivered in 2022, but down from 40TWh in 2020 and 2021. Plant biomass – mainly woodchips – is around two-thirds of these annual totals.

The four wood-burning former coal units at the Drax plant in Yorkshire account for around one-third of power from bioenergy on their own. However, their output has been subdued in 2022 and 2023, with some reporting having raised questions about the incentives at play.

Meanwhile, electricity generation from solar power only increased by 2% in 2023, despite a surge in new capacity being connected to the grid.

The number of hours of sunshine during 2023 was roughly in line with the long-term average, government figures show, whereas 2022 had been unusually sunny.

According to figures from consultancy Rystad Energy cited by Drax Electric Insights, the UK’s solar capacity was expected to rise from 15GW at the start of 2023 to 18GW by the end of the year.

Recent growth in solar installations comes after an extended period of stagnation, with installed capacity having reached 13GW in 2018 and only climbing to 14GW in 2022.

Rystad Energy expects UK solar capacity to continue accelerating, topping 25GW in 2025.

The latest reduction in coal generation, down another 33% in 2023, came as three of the UK’s four remaining coal-fired power stations shut down.

Dr Simon Evans on X: Not sure if you noticed, but as of yesterday, the UK only had one coal-fired power station remaining

West Burton in Nottinghamshire closed in March, then Drax in Yorkshire closed in April, followed by Kilroot in Northern Ireland at the end of September.

Only Ratcliffe in Nottinghamshire, operated by utility firm Uniper, remains operational. It plans to close in September 2024, ahead of the government’s ambition to end coal power by October 2024.

While the UK saw a major coal-to-gas transition in the 1990s “dash for gas”, recent reductions in coal use have been driven by renewables and reduced demand. These same forces have also been driving gas out of the mix.

The large drop in gas generation in 2023 of 27TWh (21%) reflects a combination of this longer-term trend with a one-off flip in the UK’s electricity imports.

The dip in the dark blue line for “oil, imports and other” in 2022 is due to the UK becoming a net electricity exporter that year for the first time ever.

Every year since the opening of the first “interconnector” linking the grids of the UK and France in 1986, the UK has been a net electricity importer – apart from 2022.

The switch in 2022 was due to widespread outages in the French nuclear fleet, with neighbouring countries including the UK picking up the slack.

In 2023, the UK reverted to being a net importer, buying 23TWh of electricity from countries including France, the Netherlands, Belgium and Norway. This was similar to 2021 (25TWh).

The switch from being a net exporter of 5TWh in 2022 to net imports of 23TWh in 2023 combined with steady output from renewables and falling demand to push down the need for fossil fuels.

The UK now has 8.4 gigawatts (GW) of interconnector capacity to link its electricity system with that of neighbouring countries. Some 4.4GW of this has been added in the past five years.

In addition, the 1.4GW Viking Link interconnector between the UK and Denmark was completed in late 2023 and was due to have started operating in late December.

Another 4.7GW has regulatory approval, with further projects totalling 5.6GW also planned.

Cleanest power

With fossil fuels reaching a record-low 33% share and coal down to 1% of the total, the UK saw its lowest-carbon electricity mix ever in 2023.

The carbon intensity of electricity – in other words, the amount of CO2 associated with each unit of electricity – fell to a record-low 162gCO2/kWh in 2023, a reduction of 18% year-on-year.

This continues a longer-term trend, shown in the figure below. In the early years of the series, the reductions in carbon intensity reflect a shift towards more efficient power plants.

The expansion of nuclear power in the 1970s and 1980s was followed by the “dash for gas”, which is lower-carbon than coal. From around 2008, the decline is due to the rise of renewables.

Electricity generated in 2023 was the cleanest ever

The government had earlier set a goal of reducing the carbon intensity of electricity generation to below 100gCO2/kWh by 2030. Since then, the UK’s 2050 climate target has been strengthened from an 80% cut in emissions to a 100% cut – reaching net-zero by that date.

If the government reaches its aim of 95% low-carbon electricity by 2030 then the carbon intensity of generation would fall to well-below 100gCO2/kWh. Just how far below would depend on the contribution from bioenergy and whether CO2 associated with imported electricity is counted.

The figure above counts bioenergy lifecycle emissions and imports towards the total.

Methodology

The figures in the article are from Carbon Brief analysis of data from DESNZ Energy Trends chapter 5 and chapter 6, as well as from BM Reports. The figures from BM Reports are for electricity supplied to the grid in Great Britain only and are adjusted to include Northern Ireland.

In Carbon Brief’s analysis, the BM Reports numbers are also adjusted to account for electricity used by power plants on site and for generation by plants not connected to the high-voltage national grid. This includes many onshore windfarms, as well as industrial gas combined heat and power plants and those burning landfill gas, waste or sewage gas.

The analysis of carbon intensity is based on the methodology published by National Grid ESO, but also takes account of fuel use efficiency for earlier years.

DESNZ historical electricity data, including years before 2009, is adjusted in line with other figures and combined with data on imports from a separate DESNZ dataset. Note that the data prior to 1951 only includes “major” power producers.

The 2026 budget test: Will Australia break free from fossil fuels?

Published

on

In 2026, the dangers of fossil fuel dependence have been laid bare like never before. The illegal invasion of Iran has brought pain and destruction to millions across the Middle East and triggered a global energy crisis impacting us all. Communities in the Pacific have been hit especially hard by rising fuel prices, and Australians have seen their cost-of-living woes deepen.

Such moments of crisis and upheaval can lead to positive transformation. But only when leaders act with courage and foresight.

There is no clearer statement of a government’s plans and priorities for the nation than its budget — how it plans to raise money, and what services, communities, and industries it will invest in.

As we count down the days to the 2026-27 Federal Budget, will the Albanese Government deliver a budget for our times? One that starts breaking the shackles of fossil fuels, accelerates the shift to clean energy, protects nature, and sees us work together with other countries towards a safer future for all? Or one that doubles down on coal and gas, locks in more climate chaos, and keeps us beholden to the whims of tyrants and billionaires.

Here’s what we think the moment demands, and what we’ll be looking out for when Treasurer Jim Chalmers steps up to the dispatch box on 12 May.

1. Stop fuelling the fire
2. Make big polluters pay
3. Support everyone to be part of the solution
4. Build the industries of the future
5. Build community resilience
6. Be a better neighbour
7. Protect nature

1. Stop fuelling the fire

In mid-April, Pacific governments and civil society met to redouble their efforts towards a Fossil Fuel Free Pacific. Moving beyond coal, oil and gas is fundamental to limiting warming to 1.5°C — a survival line for vulnerable communities and ecosystems. And as our Head of Pacific, Shiva Gounden, explained, it is “also a path of liberation that frees us from expensive, extractive and polluting fossil fuel imports and uplifts our communities”.

Pacific countries are at the forefront of growing global momentum towards a just transition away from fossil fuels, and it is way past time for Australia to get with the program. It is no longer a question of whether fossil fuel extraction will end, but whether that end will be appropriately managed and see communities supported through the transition, or whether it will be chaotic and disruptive.

So will this budget support the transition away from fossil fuels, or will it continue to prop up coal and gas?

When it comes to sensible moves the government can make right now, one stands out as a genuine low hanging fruit. Mining companies get a full rebate of the excise (or tax) that the rest of us pay on diesel fuel. This lowers their operating costs and acts as a large, ongoing subsidy on fossil fuel production — to the tune of $11 billion a year!

Greenpeace has long called for coal and gas companies to be removed from this outdated scheme, and for the billions in savings to be used to support the clean energy transition and to assist communities with adapting to the impacts of climate change. Will we see the government finally make this long overdue change, or will it once again cave to the fossil fuel lobby?

2. Make big polluters pay

While our communities continue to suffer the escalating costs of climate-fuelled disasters, our Government continues to support a massive expansion of Australia’s export gas industry. Gas is a dangerous fossil fuel, with every tonne of Australian gas adding to the global heating that endangers us all.

Moreover, companies like Santos and Woodside pay very little tax for the privilege of digging up and selling Australians’ natural endowment of fossil gas. Remarkably, the Government currently raises more tax from beer than from the Petroleum Resource Rent Tax (PRRT) — the main tax on gas profits.

Momentum has been building to replace or supplement the PRRT with a 25% tax on gas exports. This could raise up to $17 billion a year — funds that, like savings from removing the diesel tax rebate for coal and gas companies, could be spent on supporting the clean energy transition and assisting communities with adapting to worsening fires, floods, heatwaves and other impacts of climate change.

As politicians arrive in Canberra for budget week, they will be confronted by billboards calling for a fair tax on gas exports. The push now has the support of dozens of organisations and a growing number of politicians. Let’s hope the Treasurer seizes this rare window for reform.

3. Support everyone to be part of the solution

As the price of petrol and diesel rises, electric vehicles (EVs) are helping people cut fuel use and save money. However, while EV sales have jumped since the invasion of Iran sent fuel prices rising, they still only make up a fraction of total new car sales. This budget should help more Australians switch to electric vehicles and, even more importantly, enable more Australians to get around by bike, on foot, and on public transport. This means maintaining the EV discount, investing in public and active transport, and removing tax breaks for fuel-hungry utes and vans.

Millions of Australians already enjoy the cost-saving benefits of rooftop solar, batteries, and getting off gas. This budget should enable more households, and in particular those on lower incomes, to access these benefits. This means maintaining the Cheaper Home Batteries Program, and building on the Household Energy Upgrades Fund.

4. Build the industries of the future

If we’re to transition away from fossil fuels, we need to be building the clean industries of the future.

No state is more pivotal to Australia’s energy and industrial transformation than Western Australia. The state has unrivaled potential for renewable energy development and for replacing fossil fuel exports with clean exports like green iron. Such industries offer Western Australia the promise of a vibrant economic future, and for Australia to play an outsized positive role in the world’s efforts to reduce emissions.

However, realising this potential will require focussed support from the Federal Government. Among other measures, Greenpeace has recommended establishing the Australasian Green Iron Corporation as a joint venture between the Australian and Western Australian governments, a key trading partner, a major iron ore miner and steel makers. This would unite these central players around the complex task of building a large-scale green iron industry, and unleash Western Australia’s potential as a green industrial powerhouse.

5. Build community resilience

Believe it or not, our Government continues to spend far more on subsidising fossil fuel production — and on clearing up after climate-fuelled disasters — than it does on helping communities and industries reduce disaster costs through practical, proven methods for building their resilience.

Last year, the Government estimated that the cost of recovery from disasters like the devastating 2022 east coast floods on 2019-20 fires will rise to $13.5 billion. For contrast, the Government’s Disaster Ready Fund – the main national source of funding for disaster resilience – invests just $200 million a year in grants to support disaster preparedness and resilience building. This is despite the Government’s own National Emergency Management Agency (NEMA) estimating that for every dollar spent on disaster risk reduction, there is a $9.60 return on investment.

By redirecting funds currently spent on subsidising fossil fuel production, the Government can both stop incentivising climate destruction in the first place, and ensure that Australian communities and industries are better protected from worsening climate extremes.

No communities have more to lose from climate damage, or carry more knowledge of practical solutions, than Aboriginal and Torres Strait Islander peoples. The budget should include a dedicated First Nations climate adaptation fund, ensuring First Nations communities can develop solutions on their own terms, and access the support they need with adapting to extreme heat, coastal erosion and other escalating challenges.

6. Be a better neighbour

The global response to climate change depends on the adequate flow of support from developed economies like Australia to lower income nations with shifting to clean energy, adapting to the impacts of climate change, and addressing loss and damage.

Such support is vital to building trust and cooperation, reducing global emissions, and supporting regional and global security by enabling countries to transition away from fossil fuels and build greater resilience.

Despite its central leadership role in this year’s global climate negotiations, our Government is yet to announce its contribution to international climate finance for 2025-2030. Greenpeace recommends a commitment of $11 billion for this five year period, which is aligned with the global goal under the Paris Agreement to triple international climate finance from current levels.
This new commitment should include additional funding to address loss and damage from climate change and a substantial contribution to the Pacific Resilience Facility, ensuring support is accessible to countries and communities that need it most. It should also see Australia get firmly behind the vision of a Fossil Fuel Free Pacific.

7. Protect nature

There is no safe planet without protection of the ecosystems and biodiversity that sustain us and regulate our climate.

Last year the Parliament passed important and long overdue reforms to our national environment laws to ensure better protection for our forests and other critical ecosystems. However, the Government will need to provide sufficient funding to ensure the effective implementation of these reforms.

Greenpeace has recommended $500 million over four years to establish the National Environment Agency — the body responsible for enforcing and monitoring the new laws — and a further $50 million to Environment Information Australia for providing critical information and tools.

Further resourcing will also be required to fulfil the crucial goal of fully protecting 30% of Australian land and seas by 2030. This should include $1 billion towards ending deforestation by enabling farmers and loggers to retool away from destructive practices, $2 billion a year for restoring degraded lands, $5 billion for purchasing and creating new protected areas, and $200 million for expanding domestic and international marine protected areas.

Conclusion

This is not the first time that conflict overseas has triggered an energy crisis, or that a budget has been preceded by a summer of extreme weather disasters, highlighting the urgent need to phase out fossil fuels. What’s different in 2026 is the availability of solutions. Renewable energy is now cheaper and more accessible than ever before. Global momentum is firmly behind the transition away from fossil fuels. The Albanese Government, with its overwhelming majority, has the chance to set our nation up for the future, or keep us stranded in the past. Let’s hope it makes some smart choices.

What fossil fuels really cost us in a world at war

Published

on

Anne Jellema is Executive Director of 350.org.

The war on Iran and Lebanon is a deeply unjust and devastating conflict, killing civilians at home, destroying lives, and at the same time sending shockwaves through the global economy. We, at 350.org, have calculated, drawing on price forecasts from the International Monetary Fund (IMF) and Goldman Sachs, just how much that volatility is costing us. 

Even under the IMF’s baseline scenario – a de facto “best case” scenario with a near-term end to the war and related supply chain disruptions – oil and gas price spikes are projected to cost households and businesses globally more than $600 billion by the end of the year. Under the IMF’s “adverse scenario”, with prolonged conflict and sustained price pressures, we estimate those additional costs could exceed $1 trillion, even after accounting for reduced demand.

Which is why we urgently need a power shift. Governments are under growing pressure to respond to rising fuel and food costs and deepening energy poverty. And it’s becoming clearer to both voters and elected officials that fossil dependence is not only expensive and risky, but unnecessary. 

People who can are voting with their wallets: sales of solar panels and electric vehicles are increasing sharply in many countries. But the working people who have nothing to spare, ironically, are the ones stuck with using oil and gas that is either exorbitantly expensive or simply impossible to get.

Drain on households and economies

In India, street food vendors can’t get cooking gas and in the Philippines, fishermen can’t afford to take their boats to sea. A quarter of British people say that rising energy tariffs will leave them completely unable to pay their bills. This is the moment for a global push to bring abundant and affordable clean energy to all.

In April, we released Out of Pocket, our new research report on how fossil fuels are draining households and economies. We were surprised by the scale of what we found. For decades, governments have reassured people that energy price spikes are unfortunate but unavoidable – the result of distant conflicts, market forces or geopolitical shocks beyond anyone’s control. But the numbers tell a different story. 

    What we are living through today is not an energy crisis. It is a fossil fuel crisis. In just the first 50 days of the Middle East conflict, soaring oil and gas prices have siphoned an estimated $158 billion–$166 billion from households and businesses worldwide. That is money extracted directly from people’s pockets and transferred, almost instantly, into fossil fuel company balance sheets. And this figure only captures the immediate impact of price spikes, not the permanent economic drain of fossil dependence. Fossil fuels don’t just cost us once, they cost us over and over again.

    First, through our bills. Every time there is a war, an embargo or a supply disruption, fossil fuel prices surge. For ordinary people, this means higher costs for energy, transport and food. Many Global South countries have little or no fiscal space to buffer the shock; instead, workers and families pay the price.

    Second, through our taxes. Governments around the world continue to pour vast sums of public money into fossil fuel subsidies. These are often justified as a way to protect the most vulnerable at the petrol pump or in their homes. But in reality, the benefits are overwhelmingly captured by wealthier households and corporations. The poorest 20% receive just a fraction of this support, while public finances are drained.

    Third, through climate impacts. New research across more than 24,000 global locations gives a granular account of the true costs of extreme heat, sea level rise and falling agricultural yields. Using this data to update IMF modelling of the social cost of carbon, we found that fossil fuel impacts on health and livelihoods amount to over $9 trillion a year. This is the biggest subsidy of all, because these massive and mounting costs are not charged to Big Oil – they are paid for by governments and households, with the poorest shouldering the lion’s share. 

    Massive transfer of wealth to fossil fuel industry

    Adding up direct subsidies, tax breaks and the unpaid bill for climate damages, the total transfer of wealth from the public to the fossil fuel industry amounts to $12 trillion even in a “normal” year without a global oil shock. That’s more than 50% higher than the IMF has previously estimated, and equivalent to a staggering $23 million a minute.

    The fossil fuel industry has become extraordinarily adept at profiting from instability. When conflict drives up prices, companies do not lose, they gain. In the current crisis, oil producers and commodity traders are on track to secure tens of billions of dollars in additional windfall profits, even as households face rising bills and governments struggle to manage the fallout.

    Fossil fuel crisis offers chance to speed up energy transition, ministers say

    This growing disconnect is impossible to ignore. Investors are advised to buy into fossil fuel firms precisely because of their ability to generate profits in times of crisis. Meanwhile, ordinary people are told to tighten their belts.

    In 2026, unlike during the oil shocks of the 1970s, clean energy is no longer a distant alternative. Now, even more than when gas prices spiked due to Russia’s invasion of Ukraine in 2022, renewables are often the cheapest option available. Solar and wind can be deployed quickly, at scale, and without the volatility that defines fossil fuel markets.

    How to transition from dirty to clean energy

    The solutions are clear. Governments must implement permanent windfall taxes on fossil fuel companies to ensure that extraordinary profits generated during crises are redirected to support households. These revenues can be used to reduce energy bills, invest in public services, and accelerate the rollout of clean energy.

    Second, we must shift subsidies away from fossil fuels and towards renewable solutions, particularly those that can be deployed quickly and equitably, such as rooftop and community solar. This is not just about cutting emissions. It is about building a more stable, fair and resilient energy system.

    Finally, we need binding plans to phase out fossil fuels altogether, replacing them with homegrown renewable energy that can shield economies from future shocks. Because what the current crisis has made clear is this: as long as we remain dependent on fossil fuels, we remain vulnerable – to conflict, to price volatility and to the escalating impacts of climate change.

    The true price of fossil fuels is no longer hidden. It is visible in rising bills, strained public finances and communities pushed to the brink. And it is being paid, every day, by ordinary people around the world.

    Traditional models still ‘outperform AI’ for extreme weather forecasts

    Published

    on

    Computer models that use artificial intelligence (AI) cannot forecast record-breaking weather as well as traditional climate models, according to a new study.

    It is well established that AI climate models have surpassed traditional, physics-based climate models for some aspects of weather forecasting.

    However, new research published in Science Advances finds that AI models still “underperform” in forecasting record-breaking extreme weather events.

    The authors tested how well both AI and traditional weather models could simulate thousands of record-breaking hot, cold and windy events that were recorded in 2018 and 2020.

    They find that AI models underestimate both the frequency and intensity of record-breaking events.

    A study author tells Carbon Brief that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.

    AI weather forecasts

    Extreme weather events, such as floods, heatwaves and storms, drive hundreds of billions of dollars in damages every year through the destruction of cropland, impacts on infrastructure and the loss of human life.

    Many governments have developed early warning systems to prepare the general public and mobilise disaster response teams for imminent extreme weather events. These systems have been shown to minimise damages and save lives.

    For decades, scientists have used numerical weather prediction models to simulate the weather days, or weeks, in advance.

    These models rely on a series of complex equations that reproduce processes in the atmosphere and ocean. The equations are rooted in fundamental laws of physics, based on decades of research by climate scientists. As a result, these models are referred to as “physics-based” models.

    However, AI-based climate models are gaining popularity as an alternative for weather forecasting.

    Instead of using physics, these models use a statistical approach. Scientists present AI models with a large batch of historical weather data, known as training data, which teaches the model to recognise patterns and make predictions.

    To produce a new forecast, the AI model draws on this bank of knowledge and follows the patterns that it knows.

    There are many advantages to AI weather forecasts. For example, they use less computing power than physics-based models, because they do not have to run thousands of mathematical equations.

    Furthermore, many AI models have been found to perform better than traditional physics-based models at weather forecasts.

    However, these models also have drawbacks.

    Study author Prof Sebastian Engelke, a professor at the research institute for statistics and information science at the University of Geneva, tells Carbon Brief that AI models “depend strongly on the training data” and are “relatively constrained to the range of this dataset”.

    In other words, AI models struggle to simulate brand new weather patterns, instead tending forecast events of a similar strength to those seen before. As a result, it is unclear whether AI models can simulate unprecedented, record-breaking extreme events that, by definition, have never been seen before.

    Record-breaking extremes

    Extreme weather events are becoming more intense and frequent as the climate warms. Record-shattering extremes – those that break existing records by large margins – are also becoming more regular.

    For example, during a 2021 heatwave in north-western US and Canada, local temperature records were broken by up to 5C. According to one study, the heatwave would have been “impossible” without human-caused climate change.

    The new study explores how accurately AI and physics-based models can forecast such record-breaking extremes.

    First, the authors identified every heat, cold and wind event in 2018 and 2020 that broke a record previously set between 1979 and 2017. (They chose these years due to data availability.) The authors use ERA5 reanalysis data to identify these records.

    This produced a large sample size of record-breaking events. For the year 2020, the authors identified around 160,000 heat, 33,000 cold and 53,000 wind records, spread across different seasons and world regions.

    For their traditional, physics-based model, the authors selected the High RESolution forecast model from the Integrated Forecasting System of the European Centre for Medium-­Range Weather Forecasts. This is “widely considered as the leading physics-­based numerical weather prediction model”, according to the paper.

    They also selected three “leading” AI weather models – the GraphCast model from Google Deepmind, Pangu-­Weather developed by Huawei Cloud and the Fuxi model, developed by a team from Shanghai.

    The authors then assessed how accurately each model could forecast the extremes observed in the year 2020.

    Dr Zhongwei Zhang is the lead author on the study and a researcher at Karlsruhe Institute of Technology. He tells Carbon Brief that many AI weather forecast models were built for “general weather conditions”, as they use all historical weather data to train the models. Meanwhile, forecasting extremes is considered a “secondary task” by the models.

    The authors explored a range of different “lead times” – in other words, how far into the future the model is forecasting. For example, a lead time of two days could mean the model uses the weather conditions at midnight on 1 January to simulate weather conditions at midnight on 3 January.

    The plot below shows how accurately the models forecasted all extreme events (left) and heat extremes (right) under different lead times. This is measured using “root mean square error” – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy.

    The chart on the left shows how two of the AI models (blue and green) performed better than the physics-based model (black) when forecasting all weather across the year 2020.

    However, the chart on the right illustrates how the physics-based model (black) performed better than all three AI models (blue, red and green) when it came to forecasting heat extremes.

    Accuracy of the AI models

This is measured using “root mean square error” (RMSE) – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy. Source: Zhang et al (2026).

    The authors note that the performance gap between AI and physics-based models is widest for lower lead times, indicating that AI models have greater difficulty making predictions in the near future.

    They find similar results for cold and wind records.

    In addition, the authors find that AI models generally “underpredict” temperature during heat records and “overpredict” during cold records.

    The study finds that the larger the margin that the record is broken by, the less well the AI model predicts the intensity of the event.

    ‘Warning shot’

    Study author Prof Erich Fischer is a climate scientist at ETH Zurich and a Carbon Brief contributing editor. He tells Carbon Brief that the result is “not unexpected”.

    He adds that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.

    The analysis, he continues, is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.

    AI models are likely to continue to improve, but scientists should “not yet” fully replace traditional forecasting models with AI ones, according to Fischer.

    He explains that accurate forecasts are “most needed” in the runup to potential record-breaking extremes, because they are the trigger for early warning systems that help minimise damages caused by extreme weather.

    Leonardo Olivetti is a PhD student at Uppsala University, who has published work on AI weather forecasting and was not involved in the study.

    He tells Carbon Brief that “many other studies” have identified issues with using AI models for “extremes”, but this paper is novel for its specific focus on extremes.

    Olivetti notes that AI models are already used alongside physics-based models at “some of the major weather forecasting centres around the world”. However, the study results suggest “caution against relying too heavily on these [AI] models”, he says.

    Prof Martin Schultz, a professor in computational earth system science at the University of Cologne who was not involved in the study, tells Carbon Brief that the results of the analysis are “very interesting, but not too surprising”.

    He adds that the study “justifies the continued use of classical numerical weather models in operational forecasts, in spite of their tremendous computational costs”.

    Advances in forecasting

    The field of AI weather forecasting is evolving rapidly.

    Olivetti notes that the three AI models tested in the study are an “older generation” of AI models. In the last two years, newer “probabilistic” forecast models have emerged that “claim to better capture extremes”, he explains.

    The three AI models used in the analysis are “deterministic”, meaning that they only simulate one possible future outcome.

    In contrast, study author Engelke tells Carbon Brief that probabilistic models “create several possible future states of the weather” and are therefore more likely to capture record-breaking extremes.

    Engelke says it is “important” to evaluate the newer generation of models for their ability to forecast weather extremes.

    He adds that this paper has set out a “protocol” for testing the ability of AI models to predict unprecedented extreme events, which he hopes other researchers will go on to use.

    The study says that another “promising direction” for future research is to develop models that combine aspects of traditional, physics-based weather forecasts with AI models.

    Engelke says this approach would be “best of both worlds”, as it would combine the ability of physics-based models to simulate record-breaking weather with the computational efficiency of AI models.

    Dr Kyle Hilburn, a research scientist at Colorado State University, notes that the study does not address extreme rainfall, which he says “presents challenges for both modelling and observing”. This, he says, is an “important” area for future research.
