Renewable energy has overtaken coal to become the world’s largest source of electricity in 2025, according to thinktank Ember.

The growth of solar and wind meant that, for the first time since 1919, the share of coal power was lower than that of renewables.

Fossil-fuel generation fell by 0.2% in 2025, the thinktank’s latest annual review says, with wind and solar alone meeting 99% of the growth in electricity demand last year.

While generation from fossil fuels has occasionally fallen year-on-year in the past, Ember says this is the first time it has happened due to the structural shift towards clean power, rather than due to economic crises or other one-off events

Record solar generation was key to pushing fossil fuels into reverse, increasing 30% year-on-year – meaning it met 75% of global electricity demand growth in 2025 alone.

Other findings include:

  • Solar power generation grew by a record 636 terawatt hours (TWh) in 2025. This exceeded the electricity that could be generated from all liquid natural gas (LNG) exports through the strait of Hormuz.
  • Wind saw the second-largest increase in generation, growing 205TWh.
  • Coal power continued to fall, meaning, for the first time in history, it accounted for less than a third of global electricity generation.
  • The global electric vehicle (EV) fleet continued to grow, displacing 1.8m barrels per day (mbpd) of oil demand in 2025. New EVs alone in 2025 displaced 0.5mbpd.

Record renewables

In 2025, both solar and wind power generation continued their recent rapid growth, according to Ember.

Solar saw a record increase, with global generation growing by 636 terawatt hours (TWh) – double the total annual electricity demand of the UK. This was 33% higher than the previous solar record growth, set just the year before (479TWh).

Global solar growth in 2025 alone exceeded the electricity that could be generated from all liquid natural gas (LNG) exports through the strait of Hormuz that year, Ember notes. This amounted to 81m tonnes (Mt) or around 550TWh of gas-fired electricity.

Solar in 2025 represented the largest annual increase of any individual electricity source ever, Ember says, with the exception of the rebound in coal generation after the Covid-19 pandemic in 2021 (719TWh).

The continued growth of solar generation last year reflects structural capacity expansion rather than fluctuations in demand. Moreover, 2025 was the fourth year in a row that solar recorded the largest absolute growth of any electricity source.

Solar capacity grew by a record 647 gigawatts (GW) in 2025. This suggests that the technology will continue to dominate generation growth in the coming years, says Ember.

Wind saw the second-largest increase in generation, growing 205TWh (8.2%) in 2025. This was the same rate as seen in 2024, but fell slightly below the record absolute increase seen in 2021 of 265TWh.

Nuclear rose moderately by 35TWh (1.3%), bringing it to an all-time high of 2,812TWh. This was driven by reactors coming online in China (37TWh), as well as increased output in France (12TWh) and Japan (9TWh), which balanced out reductions elsewhere.

However, despite nuclear generation growth, both solar and wind are expected to overtake the technology in 2026, as shown in the chart below.

Increasingly, solar and wind are dominating the electricity generation mix. This allowed renewable technologies, collectively, to surpass coal in the first six months of 2025, before successfully overtaking it across the whole year, as shown in Ember’s report.

This marks the first time in history that coal power accounted for less than a third of global electricity generation, it says.

In addition, for the first time, the growth of clean-power sources has pushed fossil-fuel generation into reverse, as shown in the chart below.

While there have been annual declines in fossil-fuel generation in the past, these were all caused by economic crises or other one-off shocks, such as the global financial crisis in 2008-9 or the coronavirus pandemic in 2020.

Tipping points

The share of wind and solar power in the global electricity mix has risen by more than 10 percentage points over the past decade, from 23% to 33.8%, according to Ember. Over the same time period, the share of coal has dropped from 38.7% to 33.0% in 2025.

Indeed, 81% of all wind and solar generation growth since 2000 occurred over the past 10 years. In contrast, only 27% of fossil-fuel growth since 2000 happened over the past 10 years, as the balance continues to tip towards renewables.

Had wind and solar not grown since 2000, electricity generation from fossil fuels would have been 30% higher in 2025 and emissions 28% higher, Ember says, adding 4,065Mt of carbon dioxide equivalent (CO2e) annually.

It says that the expected growth in clean power will tip fossil-fuel use in the power sector firmly into decline, as well as “aiding decarbonisation in other sectors”.

Renewables have overtaken coal in every region of the world, except Asia. Coal power fell by 63TWh (-0.6%) in 2025. However, at 10,476TWh, coal remained the largest single source of electricity globally.

Gas generation saw a small increase of 36TWh (0.5%) to 6,919TWh in 2025.

Despite Asia being the only region where coal generation has not been overtaken by renewables, two of the world’s biggest emitters on the continent did see fossil-fuel generation fall.

Fossil generation fell in both China (-56TWh/-0.9%) and India (-52TWh/-3.3%) due to rapid clean-power deployment and moderate demand growth, according to Ember.

This is in line with analysis for Carbon Brief earlier this year, which also found that coal power fell in China and India concurrently for the first time in 52 years.

Combined, China and India made up 42% of global fossil-fuel generation in 2025, according to Ember, offsetting a small increase in the US, EU and other economies.

In 1919, when electricity demand was 300 times smaller than in 2025, renewables – mostly hydropower – briefly exceeded coal power.

Over the following 100 years, coal power remained the largest power source globally. Its share in the power mix was around 40% from the 1970s through to the mid-2010s.

The chart below shows the growth of renewables since 2000, has allowed the technologies to overtake coal generation in 2025.

Emissions impact

The growth of clean power generation has helped to decouple demand growth from emissions growth, according to Ember’s report.

Global electricity demand grew by 2.8% (849TWh) in 2025. While this was significantly below the 4.3% growth seen in 2024, it was broadly in line with the 10-year average annual increase of 2.7%.

Last year’s increase still represents the sixth-largest absolute annual rise ever recorded.

Ember analysis suggests that if demand and clean electricity growth continue at their recent pace, then fossil-fuel generation will plateau before starting to decline consistently from the early 2030s.

With renewable energy growth pushing fossil fuels down in 2025, however, power-sector emissions fell slightly despite the increase in demand.

In 2025, the average kilowatt hour produced globally resulted in emissions of 458gCO2e, some 2.7% less than in 2024 (471gCO2e) and down 16% from 2005 (543gCO2e).

Electrification of key sectors is expected to add to rising electricity demand in the coming years, Ember notes, pointing to transport and data centres.

(Note that while demand from electric vehicles and data centres is rising quickly, they are still “relatively slim” in terms of their contribution to overall growth, according to the International Energy Agency. Industry and buildings are the largest sources of growth.)

In 2025, electric vehicle (EV) sales reached more than 25% of the global car market. As a result, Ember says that EVs are becoming a “structural driver of electricity demand growth”, accounting for about 8% (66TWh) of the 849TWh rise in global electricity demand in 2025. This is up from 36TWh in 2024.

In addition, the global EV fleet displaced 1.8m barrels per day (mbpd) of oil demand in 2025. New EVs alone in 2025 displaced 0.5mbpd.

The oil demand displaced through additional transport electrification in 2025 will avoid roughly 80MtCO2e emissions annually, more than the annual power sector emissions of the UK, it says.

Further expansion of renewables to help meet growing demand from sectors such as transport is being supported by the rollout of storage technologies.

Falling battery prices are driving a rapid scale-up in deployments. Battery pack prices for stationary storage applications fell to a record low of $70/kWh in 2025, Ember says – a 45% drop from 2024.

Global battery storage capacity additions reached an estimated 247 gigawatt hours (GWh), up 46% year-on-year. This would be enough to shift about 14% of daily solar generation to other hours, up from 13% in 2024 and just 5% in 2022, according to Ember.

UN chief warns climate crisis “in overdrive” as El Niño threatens to fuel the fire

Published

on

The United Nations Secretary-General and foreign ministers from the UK, France and Spain have blamed the deadly wildfires engulfing Europe on climate change, using the disaster to renew calls for faster cuts to greenhouse gas emissions.

António Guterres told journalists on Friday that the “climate crisis is in overdrive”, adding that global heat seen so far is just a “warm up act” as a phenomenon known as El Niño intensifies “adding fuel to a planet already on fire”.

A new World Meteorological Organisation (WMO) report published on Friday predicts that the weather pattern will grow into a “strong event” between now and October, increasing the risk of higher than normal temperatures across much of the world and disrupted rainfalls.

“That risks shattering every seasonal record – and driving even more severe effects worldwide,” Guterres said.

El Niño builds on top of an already warming world, driven primarily by the burning of fossil fuels. A WMO scientist, who did not want to be named, told journalists that all the heatwaves and other climate impacts seen so far this year are “before the effects of El Niño are really kicking in at a global scale”.

Fossil fuellling the fires

Fires have broken out across much of Europe but are threatening the most people in the south-west of France near Bordeaux and in Central Spain near Madrid. Nearly a quarter of a million people have been evacuated in France with hundreds of homes destroyed while in Spain 80,000 people have had to leave their homes and at least 13 died in one village.

A scientific study published on Friday by the World Weather Attribution group found that man-made climate change made deadly fires in France twice as likely and those in Spain twenty times more likely. Smaller fires in the UK were not analysed by the study.

UN Climate Change leader Simon Stiell blamed fossil fuels for the fires, as well as storms in Chile and heatwaves in North America and Japan in recent weeks. “The climate alarm is blaring”, he said on Wednesday.

Guterres criticised new fossil fuel production projects and fossil fuel subsidies for causing hardship across the world. Discussing his speech, a senior UN official – who did not want to be named – said the subsidies amounted to trillions of US dollars a year and criticised pension funds and institutional investors, including insurance companies, for continuing to invest in fossil fuel projects.

Asked why world leaders and the public are not prioritising climate action, Guterres said they are distracted by wars in Ukraine, the Middle East, Sudan and elsewhere and sometimes forget “other aspects that are a sometimes even more dangerous threat”.

Also the fossil fuel industry and “some countries” are campaigning to pretend that climate change does not exist, he said, adding that the UN should be more active in “naming the situations as they are and the responsibilties as they are and mobilising the public opinion”.

After meetings in Paris and Madrid earlier in the week, the UK’s new foreign minister Ed Miliband issued joint statements with his French and Spanish counterparts – Jean-Noël Barrot and José Manuel Albares Bueno – calling on the world to reduce its dependence on fossil fuels.

They promised to do more to reduce emissions and protect their people and encouraged other governments to do the same.

The UK-French statement called on governments to publish UN climate plans, known as nationally determined contributions (NDCs), which are aligned with the Paris Agreement’s goal to limit global average temperatures to 1.5C above pre-industrial levels.

According to Climate Action Tracker, only three countries – the UK, Nigeria and Norway – have submitted NDCs with 2035 emissions reduction targets which are compatible with 1.5C. Fifty-two countries – including Egypt, Vietnam and Argentina – have yet to submit an NDC at all.

Defending science

Beyond action on emissions, the ministers also intervened in an ongoing dispute over the timing of the Intergovernmental Panel on Climate Change’s (IPCC)’s next flagship assessment.

Miliband and Barrot’s statement said they “underline the importance” of scientific report feeding into governments’ next global stocktake of progress on climate action in two years’ time, calling it a “critical input” to that process.

The timing of this report has been a contentious issue in government negotiations at the IPCC and at June’s climate talks in Bonn. While a group of nations calling themselves the “friends of science” want the report before the stocktake, others like Saudi Arabia and India have argued that this would make the report of a worse quality and less inclusive of developing countries’ scientists.

Science ‘under attack’ from fossil fuel interests at UN climate talks

The UK-Spanish statement weighed in less explicitly on this issue but said that they “recall the importance of scientific evidence and acknowledge the work of the IPCC in this respect.”

The British and French ministers said they would seek to accelerate reductions of emissions in methane, a particularly potent greenhouse gas, at COP31 in November. They encouraged governments “to work jointly to develop a marketplace for fossil fuels with near-zero methane intensity.”

Methane leaks from oil, gas and coal production are a major contributor to global warming. Over a 20-year period, methane traps around 80 times more heat than carbon dioxide.

The UK and Spanish statement emphasised the importance of supporting the Global South and underlined the need to mobilise sustainable financing “at scale with the challenge we face”. The previous UK government, in which Miliband was energy minister, cut climate finance to developing countries to pay for increases in military spending.

The UK government led by new Prime Minister Andy Burnham has yet to outline any major changes to climate finance in its two weeks in power but has announced it will convert some finance from grants to loans in order to free up money to subsidise bus travel in England.

More adaptation needed

Guterres said that “it is time to stop treating each disaster as an isolated tragedy and recognise the systemic risk that is unfolding before our eyes.” A recent study found that three-quarters of UK media reports about the British June heatwave did not mention climate change.

As well as reducing emissions, the UN Secretary-General called for measures to adapt vulnerable people to extreme heat. Specifically, he said that buildings should be built and retrofitted for extreme heat and that every city and country should have heat-health action plans and early warning systems. Over 250 cities have joined the UN’s ‘beat the heat’ initiative, he said.

The Portuguese diplomat called for governments and employers to do more to protect their workers from heat, criticising global fashion brands for not setting heat standards for the factories that supply them. “No one should have to risk their life to earn a living,” he said.

‘Ride the wave of momentum’: Australia announces once-in-a-decade Marine Parks Network review

Published

on

In response to the federal government announcing its once-in-a-decade review of Australia’s Marine Parks Network, the following lines can be attributed to Elle Lawless, Senior Campaigner at Greenpeace Australia Pacific:

“Greenpeace Australia Pacific welcomes today’s announcement that the Albanese Government will review Australia’s Commonwealth Marine Parks Network. This is a rare, once-in-a-decade opportunity to strengthen our marine parks and ban industrial fishing in Australia’s marine protected areas.

“Australians would be appalled to know that more than half of Australia’s Marine Parks Network currently allows for extractive industries, like longlining, bottom trawling and oil and gas mining. These so-called ‘protected’ areas were designed to safeguard our beloved ocean wildlife and underwater ecosystems – that is what Australians expect. Damaging industrial industries should not be given a free pass to trawl, fish, drill or extract from our marine parks.”

“With the first Ocean COP just around the corner, and off the back of Australia’s move to ratify the Global Ocean Treaty earlier this year, the Australian government has a unique opportunity to ride the wave of this momentum and solidify itself as a true global ocean leader.

“Greenpeace Australia Pacific is calling for industrial activities to be banned from our protected waters and for at least 30% of Australia’s ocean to be protected as ocean sanctuaries. This review presents a rare opportunity to create more ocean sanctuaries, true blue havens where ocean life can recover, thrive and repopulate the surrounding waters.”

Factcheck: No, Europe is not having its ‘quietest’ year for wildfires

Published

on

In recent days, prominent climate sceptics and rightwing commentators have shared charts on social media incorrectly implying that Europe is having its “quietest” year for wildfires in 2026.

These include Dr Matthew Wielicki, a former University of Alabama geochemist and self-described “professor in exile”, who was recently appointed by the Trump administration to lead the US Global Change Research Program.

However, these charts paint a misleading picture as they are skewed by encompassing the entirety of Russia in the data – including the vast plains of Siberia.

These charts also use data that include fires that are deliberately lit to manage cropland, which is a declining practice across much of Europe.

In this factcheck, Carbon Brief shows that the area burned by wildfires across the European Union in 2026 is second only to 2022 for this time of year.

The latest data from the European Forest Fire Information System (EFFIS) also shows that France has set a new modern record for area burned and Spain’s wildfire season is among the worst on record.

The fires have displaced more than a third of a million people across south-western Europe, while an impending heatwave has also raised fears of the fires worsening in the coming days.

‘Quietest year’

On 27 July, as wildfires raged across multiple European countries, former Conservative peer and climate-sceptic commentator Matt Ridley posted on Twitter that “2026 is the quietest year for wildfires in Europe by some distance”.

Misleading social media post by Mitt Ridley that says" er...2026 is the quietest year for wild fires un Europe by some distance."

Ridley, who sits on the academic advisory council of the Global Warming Policy Foundation (GWPF), a UK-based climate-sceptic lobby group that refuses to reveal the sources of its funding, was responding to an article by Daily Telegraph columnist Tim Stanley.

Stanley’s column, headlined: “Climate change is real – and the right needs to get serious about it”, warned:

“This is no longer a matter of speculation: the wildfires of Europe, pitiless and persistent, are the way we live now.”

Ridley included a chart from Our World In Data, showing the cumulative area burned by wildfires by week for Europe. The chart puts 2026 as having the smallest area for this time of year in a dataset going back to 2012.

Ridley’s post was widely shared by prominent rightwing figures – including Richard Tice, deputy leader of the hard-right, climate-sceptic Reform UK party, former Conservative cabinet minister Jacob Rees-Mogg and multiple commentators.

Separately, Wielicki also shared a chart on Twitter to imply that wildfires in Europe are declining. Wielicki has previously claimed that the “science is not settled on climate change”.

The charts posted by Ridley and Wielicki both use data from the Global Wildfire Information System (GWIS). The GWIS category for “Europe” encompasses all the countries on the continent and includes the whole of Russia.

As a result, Russia accounts for about 74% of the area included in the GWIS definition of “Europe”.

Wildfires in Russia typically account for 80-90% of the burned area in the GWIS Europe dataset. In 2026, fires in Russia are substantially below average. Therefore, including Russia in this comparison creates the false impression that wildfire activity across Europe is unusually low.

Dr Calum Cunningham, a research fellow at the University of Tasmania’s Fire Centre, says that such claims are “highly misleading”, noting that “they rely on aggregating fire activity across an enormous and climatically diverse region”. He tells Carbon Brief:

“A relatively quiet season in Russia can easily mask an exceptionally active season in France or Spain. If the analysis is focused on the regions actually experiencing the current fires, the picture is very different.

“The reality is that western Europe has experienced an extraordinary sequence of climate conditions this year.”

In contrast, the EFFIS provides a subset of wildfire data specifically for the area covered by the 27 nations of the EU, which, therefore, excludes Russia.

Another difference between the two datasets is that GWIS monitors all fires – including those on agricultural land that are intentionally set alight. The burned area as measured by GWIS contains significant cropland area.

By contrast, EFFIS uses land-cover data and other information to filter specifically for forest fires.

Looking at the EU-only data from EFFIS reveals that Europe is far from having its “quietest” year. The bloc’s burned area, as of 29 July, is almost 435,000 hectares (ha) – second only to 2022 for this time of year.

Notably, Wielicki has actually continued to post charts based on GWIS data, even after acknowledging that “includ[ing] all of Russia, including vast areas of Siberia…isn’t a good proxy for Europe”.

French fires

Even looking at EU-wide data misses the scale of this year’s wildfires for some individual countries.

The chart below shows the surge in burned area in France since mid-July.

For much of the first half of the year, the country was having a wildfire season that was only slightly above average in terms of total burned area. However, a notable uptick began in the first week of July.

The third week of the month saw France break its previous cumulative annual record by more than 19,000ha. That gap has widened as the fires continue to burn; as of 29 July, the cumulative burned area in France during 2026 was nearly 24,700ha above the previous record.

France's wildfires in 2026 are the most widespread in modern records. Weekly cumulative burned area (hectares). A line chart shows 2026 burned area sharply rising by August to over 90,000 hectares, well above the 2006-2025 range maximum of around 65,000 and average of 15,000. Source: EFFIS - (alt text generated by Google Gemini)

The fires in France follow a record-breaking June heatwave that “dried out vegetation across the region, allowing fires to spread quickly”, wrote the New York Times.

On 27 July, French president Emmanuel Macron called a “crisis cabinet meeting” in order to address the fires “ravaging several areas of south-west France”, said France 24.

More than 220,000 people have been evacuated due to the Gironde fire, west of Bordeaux, in “what may be France’s largest peacetime evacuation”, reported the Associated Press.

In the Conversation, Cunningham and two other University of Tasmania researchers write that evacuation orders “protec[t] human lives, but makes it more likely houses and other structures will burn if there’s no one to defend them”. They add:

“There is little doubt climate change has made France and Spain’s wildfires worse. They represent yet another reason to redouble our efforts to tackle climate change and stabilise our climate.”

Central Spain scorched

While Spain’s fire season has not broken records in the same way that France’s has, it is on track to be among the worst since EFFIS began reporting data in 2006.

The chart below shows the rapid increase in burned area in Spain since 8 July. The latest data from EFFIS reveal that, as of 29 July, Spain has almost matched its previous record at this point in the year. It is also nearly five times the average area burned for this time of year.

In Spain, the wildfires have been concentrated in the central part of the country, near Madrid.

BBC News reported that the fires outside the capital have burned “an area more than twice as large as the city itself”.

Nearly 90,000 people were forced from their homes in central Spain by the fires, said the Associated Press.

Pedro Sánchez, Spain’s prime minister, called the fires a “painful expression” of climate change.

Meanwhile, the UK, French and Spanish governments have issued joint statements this week in response to the fires. The UK/Spain statement begins:

“This summer’s wildfires demonstrated that climate change was now a national security emergency facing Europe and threatening our way of life.”
