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.

Indonesia’s nickel production cuts are not enough to create a sustainable industry
Bhima Yudhistira Adhinegara is the Executive Director of the Center of Economic and Law Studies (CELIOS), an Indonesia-based economic think tank. Muhammad Zulfikar Rakhmat is the Director of the China-Indonesia desk at CELIOS.
Indonesia produces around 60% of the world’s nickel, a metal used to manufacture batteries for electric vehicles (EVs) – more than any other country in the world. But in 2026, the government sharply reduced how much of its nickel can be extracted from the ground.
Production quotas were reduced by around 40% this year compared to 2025. Weda Bay, the largest nickel mine on Earth, had its allowance cut by more than 70% and exhausted its full-year quota by the end of May, halting mining entirely; it cannot resume large-scale extraction until next year unless regulators grant an extension.
The policy has sparked a vivid debate in Indonesian policy circles: how can the country shift its strategy from a decade of mining vast quantities of cheap nickel to producing a high-value and low-carbon material that the rest of the world wants for EV batteries.
The cuts aren’t a silver bullet to clean up Indonesia’s nickel industry, whose smelters are powered by coal – the most polluting fossil fuels. But alongside stricter enforcement of environmental rules, it is one side of efforts to produce more sustainable nickel for a premium.
Restricting Indonesia’s nickel output
Production quotas were introduced to stop the collapse of nickel prices because of oversupply in the market. Prices had fallen more than 40% in 2023 alone and kept sliding as Indonesian supply kept growing, hitting a four-year low of around $13,900 a ton in late 2025.
Critics called the recent tightening of production quotas proof that Indonesia’s nickel strategy has failed, arguing that the industry shouldn’t need to throttle its own output to survive. But when assessed against what the policy was supposed to do – push up nickel prices – it has worked. Prices jumped to $20,000 a ton in May, the highest since 2024.
Chinese industry groups representing companies that have invested billions to mine and refine the country’s nickel were furious, warning Indonesia’s president Prabowo Subianto that the cuts put $50 billion worth of investment at risk. But much of that Chinese capital is sunk into smelters and processing plants built specifically to run on Indonesian ore, and cannot simply be moved elsewhere. That gives Jakarta more room to hold its ground than the warning suggests.
Stronger environmental enforcement
Since the start of the year, Indonesia’s forestry task force has seized more than four million hectares of land from mines and plantations operating illegally in protected forests, collecting over two trillion rupiah ($113 million) in fines.
This included 148 hectares seized from Weda Bay for lacking a forestry permit. The share of nickel produced from illegal small-scale mining also fell from about a quarter in 2022 to roughly 10% by 2024.
The crackdown responds to serious environmental damages in the nickel industry. On Obi Island, a waste pond collapsed after heavy rain in June 2025, flooding three villages and killing a resident. Internal company tests found chromium-6 – a carcinogen – in the water, in quantities far above the legal limit. The footprint of another mine near Raja Ampat, which is home to some of the world’s richest coral reefs, grew 60-fold in just eight years.

The market is responding to early cleanup efforts. Low-carbon nickel now sells for a real premium, roughly $18,800 to $19,300 a ton compared with $17,900 to $18,300 otherwise, as carmakers seek to source cleaner materials to comply with the European Union’s new emissions rules for imports.
In turn, this is incentivising the industry to do more to green its operations. Vale Indonesia’s smelter in South Sulawesi now runs almost entirely on hydropower, for example.
None of this addresses coal use, however. Major Indonesian nickel producers still emitted an estimated 15 million metric tons of greenhouse gases in 2023. Indonesia may be cracking down on illegal mining and rewarding cleaner producers but it is still running its mines on the dirtiest fuel available.
Unequal benefits
For Indonesia to truly benefit from producing cleaner and high-value nickel, it needs to reap the economic benefits too. Although the industry has boosted the country’s economic growth, the reality on the ground tells a different story.
Konawe in Southeast Sulawesi is home to a major smelting complex. Growth in the district jumped from 6% to 22% between 2015 and 2023, driven almost entirely by the nickel industry, according to a study by the Lowy Institute study. At the same time, poverty levels increased slightly and unemployment remained unchanged.
In Halmahera, another epicentre of the nickel industry, spending by the poorest fifth grew just 5% between 2019 and 2022, compared with 28% for the wealthiest fifth, according to a separate study.
Part of the reason for this inequality is the system for transferring mining royalties to district authorities where the mines are located. In theory, they are entitled to the largest share. But in practice, payments are delayed, companies routinely dispute what they owe and royalties are pooled and distributed across a larger area.
The Natural Resource Governance Institute has found that decentralisation handed local governments power to approve new mines faster than they could build their capacity to manage them. Higher output raises national income on paper, but local governments remain constrained by fiscal rules and infrastructure costs that scale with mining.
None of this makes the 2026 quota cuts a mistake. Indonesia has every right to defend its pricing power over a resource it controls. But limiting extraction isn’t going to fix underlying issues around environmental enforcement and revenue-sharing. That requires rules that are consistently enforced, royalties that reach communities living by the mines, and a plan to wean smelters off coal.

Risk of “catastrophic” oil spill reaching Kimberley coast found in Woodside’s Scott Reef gas drilling plans
SYDNEY, Monday 24 August 2026 – New analysis of Woodside modelling released by Greenpeace Australia Pacific and Environs Kimberley has revealed the oil and gas corporation’s plans to drill at Scott Reef could cause an oil spill up to 30 times bigger than the 2009 Montara disaster, impacting the Kimberley coastline and reaching as far as Indonesia.
The new analysis details the “catastrophic” oil spill risk put to environmental regulators for approval by Woodside in its Browse to North West Shelf Project (Browse) plans, the worst-case scenario being a blowout directly below Scott Reef, polluting whale migratory pathways and covering isolated turtle nesting ground with oil condensate.
An FOI application (F348) revealed the federal environment department (DCCEEW) asked offshore oil and gas regulator NOPSEMA to look into the oil spill risk in 2025. NOPSEMA’s response to the application refused access to its report, and one document shows DCCEEW sought further advice this year.
Greenpeace and Environs Kimberley are calling on the Federal Government to publicly release the NOPSEMA report given the risk of an uncontrolled release of oil condensate from directly below Scott Reef.
Hannah Schuch, Senior Campaigner at Greenpeace Australia Pacific, said: “Woodside is aware that drilling at Scott Reef risks a massive oil spill that would have severe, far-reaching consequences. It appears environmental regulators are aware too.
“The state and federal governments need to take this risk from Woodside’s drilling plans seriously, as they could end up allowing the worst oil spill in Australian history.
“The pygmy blue whales that migrate up and down the WA coast with their newborns each year could be swimming and feeding in toxic, oil-slicked water. Woodside’s proposal to drill at Scott Reef is an environmental disaster waiting to happen, and the WA and federal governments have one surefire way to prevent catastrophe — reject Browse.”
Martin Prichard, Executive Director at Environs Kimberley, said: “A catastrophic oil spill by Woodside would be disastrous not just for marine life in the area but also for the Kimberley’s $500 million tourism industry.
“The state and federal governments will see five marine parks on the Kimberley coast included in the risk area of a catastrophic Woodside oil spill.
“The Montara oil spill was disastrous for West Timor with the toxic oil destroying seaweed farmers’ livelihoods. The Kimberley dodged a bullet with Montara, we were lucky the spill didn’t head our way. Myself and a crew flew over the Montara oil spill and followed it as far as we could. It was like a scene from a disaster movie.”
After the WA Environmental Protection Authority deemed Browse “unacceptable” due, in part, to oil spill risk, Woodside submitted a mitigation plan based on technology that has never been used “in anger”, a weakness stated in an independent expert review of the plan.
Professor Richard Steiner, independent oil spill expert, said: “A large offshore spill is impossible to effectively contain or recover. Historically, only 2-6% of total spill volume is recovered and the ecological injury from the release of toxic hydrocarbons in the sea can be severe, extensive, and long-term.
“Here in Alaska, government research concludes that several marine populations injured by the 1989 Exxon Valdez oil spill, including whales, fish, and seabirds, are still not recovering today, 37 years later. We should expect similar long-term ecological impacts in Western Australia if there were to be a major oil spill. The only sure way to avoid the risk of a catastrophic marine oil spill is to not develop oil and gas projects in marine environments.”

Woodside’s own modelling reveals catastrophic oil spill risk at Scott Reef
What if Australia’s worst offshore oil spill hasn’t happened yet?
I’m terrified by the thought.
Our new report in partnership with Environs Kimberley analyses Woodside’s own oil spill modelling and it reveals a worst-case blowout at the corporation’s proposed Browse gas project at Scott Reef could be up to 30 times larger than the Montara oil spill – one of Australia’s worst environmental disasters to date.
Woodside’s own modelling warns that oil pollution could spread across Scott Reef, the Kimberley coast and beyond, with impacts Woodside itself describes as “severe”, “potentially irreversible” and “catastrophic”.

What’s at stake?
Scott Reef really is like nowhere else on Earth.
Scott Reef is Australia’s largest freestanding oceanic reef, a pristine marine ecosystem that has thrived for around 15 million years. About 270 kilometres off the Kimberley coast, it supports more than 2,000 marine species, including endangered pygmy blue whales, nesting green sea turtles, the endangered dusky sea snake and ancient corals.
Yet Woodside wants to drill up to 57 toxic wells around and underneath it, causing decades of deafening seismic blasting, light and noise pollution, shipping traffic and, of course, the risk of a ‘catastrophic’ oil spill.

What did Woodside’s modelling find?
Before Browse can be approved, Woodside is required to assess what could happen if something goes wrong. We analysed the corporation’s own environmental assessment documents, and the findings are deeply concerning.
Woodside’s modelling shows that the most severe Browse scenario would be the worst oil spill in Australian history, releasing up to 893,739 barrels of condensate into the Timor Sea. For context, the Montara oil spill released 30,000 barrels of oil.
A blowout of this scale could see oil spread hundreds of kilometres, reaching some of Australia’s most important marine environments, extending into Indonesian and Timor-Leste waters and even washing up along parts of the Kimberley coast. Entrained oil – oil mixed throughout the water column – is predicted to travel up to 863 kilometres from the spill site.
The modelling identifies potential impacts to at least nine marine parks, eight reefs and three Indigenous Protected Areas, as well as important habitats for endangered species, including pygmy blue whales, green sea turtles, seabirds and other marine life.

These aren’t just places on a map. They are globally significant marine ecosystems that support ancient coral reefs, endangered wildlife, tourism, fisheries and coastal communities. A spill of this scale wouldn’t simply affect one reef; it has the potential to impact an entire connected marine ecosystem.
Why this matters now
The most important thing is that Browse has not yet been approved. That means there is still time to stop Browse and the serious risks outlined in Woodside’s own modelling.
The science has been done. The risks have been modelled. The decision now rests with the Australian Government.
Governments are often forced to respond after environmental disasters happen. This is one of those rare moments where they have the opportunity to act before one does.
What you can do
Together, we still have the power to stop Woodside and save Scott Reef.
You can help by:
- Sending an email to Environment Minister Murray Watt and Prime Minister Anthony Albanese, calling on them to reject Browse.
- Sharing this story to help more Australians understand what’s at stake.
- Encouraging your friends and family to take action.
The more people who support saving Scott Reef, the harder it is for governments to approve Woodside’s drilling plans – Browse.
Together, we can ensure a reef that has existed for millions of years is known for its incredible biodiversity – not as the site of Australia’s worst oil spill.
Let’s save Scott Reef.
