Coal power generation fell in both China and India in 2025, the first simultaneous drop in half a century, after each nation added record amounts of clean energy.
The new analysis for Carbon Brief shows that electricity generation from coal in India fell by 3.0% year-on-year (57 terawatt hours, TWh) and in China by 1.6% (58TWh).
The last time both countries registered a drop in coal power output was in 1973.
The fall in 2025 is a sign of things to come, as both countries added a record amount of new clean-power generation last year, which was more than sufficient to meet rising demand.
Both countries now have the preconditions in place for peaking coal-fired power, if China is able to sustain clean-energy growth and India meets its renewable energy targets.
These shifts have international implications, as the power sectors of these two countries drove 93% of the rise in global carbon dioxide (CO2) emissions from 2015-2024.
While many challenges remain, the decline in their coal-power output marks a historic moment, which could help lead to a peak in global emissions.
Double drop
The new analysis shows that power generation from coal fell by 1.6% in China and by 3.0% in India in 2025, as non-fossil energy sources grew quickly enough in both countries to cover electricity consumption growth. This is illustrated in the figure below.

China achieved this feat even as electricity demand growth remained rapid at 5% year-on-year. In India, the drop in coal was due to record clean-energy growth combined with slower demand growth, resulting from mild weather and a longer-term slowdown.
The simultaneous drop for coal power in both countries in 2025 is the first since 1973, when much of the world was rocked by the oil crisis. Both China and India saw weak power demand growth that year, combined with increases in power generation from other sources – hydro and nuclear in the case of India and oil in the case of China.
China’s recent clean-energy generation growth, if sustained, is already sufficient to secure a peak in coal power. Similarly, India’s clean-energy targets, if they are met, will enable a peak in coal before 2030, even if electricity demand growth accelerates again.
In 2025, China will likely have added more than 300 gigawatts (GW) of solar and 100GW of wind power, both clear new records for China and, therefore, for any country ever.
Power generation from solar and wind increased by 450TWh in the first 11 months of the year and nuclear power delivering another 35TWh. This put the growth of non-fossil power generation, excluding hydropower, squarely above the 460TWh increase in demand.
Growth in clean-power generation has kept ahead of demand growth and, as a result, power-sector coal use and CO2 emissions have been falling since early 2024.
Coal use outside the power sector is falling, too, mostly driven by falling output of steel, cement and other construction materials, the largest coal-consuming sectors after power.
In India’s case, the fall in coal-fired power in 2025 was a result of accelerated clean-energy growth, a longer-term slowdown in power demand growth and milder weather, which resulted in a reduction in power demand for air conditioning.
Faster clean-energy growth contributed 44% of the reduction in coal and gas, compared to the trend in 2019-24, while 36% was contributed by milder weather and 20% by slower underlying demand growth. This is the first time that clean-energy growth has played a significant role in driving down India’s coal-fired power generation, as shown below.
Change in power generation in China and India by source and year, terawatt hours 2000-2025. Source: Analysis by Lauri Myllyvirta for Carbon Brief. Further details below.
India added 35GW of solar, 6GW wind and 3.5GW hydropower in the first 11 months of 2025, with renewable energy capacity additions picking up 44% year-on-year.
Power generation from non-fossil sources grew 71TWh, led by solar at 33TWh, while total generation increased 21TWh, similarly pushing down power generation from coal and gas.
The increase in clean power is, however, below the average demand growth recorded from 2019 to 2024, at 85TWh per year, as well as below the projection for 2026-30.
This means that clean-energy growth would need to accelerate in order for coal power to see a structural peak and decline in output, rather than a short-term blip.
Meeting the government’s target for 500GW of non-fossil power capacity by 2030, set by India’s prime minister Narendra Modi in 2021, requires just such an acceleration.
Historic moment
While the accelerated clean-energy growth in China and India has upended the outlook for their coal use, locking in declines would depend on meeting a series of challenges.
First, the power grids would need to be operated much more flexibly to accommodate increasing renewable shares. This would mean updating old power market structures – built to serve coal-fired power plants – both in China and India.
Second, both countries have continued to add new coal-fired power capacity. In the short term, this is leading to a fall in capacity utilisation – the number of hours each coal unit is able to operate – as power generation from coal falls.
(Both China and India have been adding new coal-power capacity in response to increases in peak electricity demand. This includes rising demand for air conditioning, in part resulting from extreme heat driven by the historical emissions that have caused climate change.)
If under-construction and permitted coal-power projects are completed, they would increase coal-power capacity by 28% in China and 23% in India. Without marked growth in power generation from coal, the utilisation of this capacity would fall significantly, causing financial distress for generators and adding costs for power users.
In the longer term, new coal-power capacity additions would have to be slowed down substantially and retirements accelerated, to make space for further expansion of clean energy in the power system.
Despite these challenges ahead, the drop in coal power and record increase in clean energy in China and India marks a historic moment.
Power generation in these two countries drove more than 90% of the increase in global CO2 emissions from all sources between 2015-2024 – with 78% from China and 16% from India – making their power sectors the key to peaking global emissions.
About the data
China’s coal-fired power generation until November 2025 is calculated from monthly data on the capacity and utilisation of coal-fired power plants from China Electricity Council (CEC), accessed through Wind Financial Terminal.
For December, year-on-year growth is based on a weekly survey of power generation at China’s coal plants by CEC, with data up to 25 December. This data closely predicts CEC numbers for the full month.
Other power generation and capacity data is derived from CEC and National Bureau of Statistics data, following the methodology of CREA’s monthly snapshot of energy and emissions trends in China.
For India, the analysis uses daily power generation data and monthly capacity data from the Central Electricity Authority, accessed through a dashboard published by government thinktank Niti Aayog.
The role of coal-fired power in China and India in driving global CO2 emissions is calculated from the International Energy Agency (IEA) World Energy Balances until 2023, applying default CO2 emission factors from the Intergovernmental Panel on Climate Change.
To extend the calculation to 2024, the year-on-year growth of coal-fired power generation in China and India is taken from the sources above, and the growth of global fossil-fuel CO2 emissions was taken from the Energy Institute’s Statistical Review of World Energy.
The time series of coal-fired power generation since 1971, used to establish the fact that the previous time there was a drop in both countries was 1973, was taken from the IEA World Energy Balances. This dataset uses fiscal years ending in March for India. Calendar-year data was available starting from 2000 from Ember’s yearly electricity data.

Analysis: Coal power drops in China and India for first time in 52 years after clean-energy records
Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.
The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.
Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”

DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy crisis
ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.
‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.
‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home News. This message was echoed by UK business secretary Peter Kyle, who said “doubling down on renewables” was “essential” amid “regional instability”, according to the Daily Telegraph.
China’s climate plan
PEAK COAL?: China has set out its next “five-year plan” at the annual “two sessions” meeting of the National People’s Congress, including its climate strategy out to 2030, according to the Hong Kong-based South China Morning Post. The plan called for China to cut its carbon emissions per unit of gross domestic product (GDP) by 17% from 2026 to 2030, which “may allow for continued increase in emissions given the rate of GDP growth”, reported Reuters. The newswire added that the plan also had targets to reach peak coal in the next five years and replace 30m tonnes per year of coal with renewables.
ACTIVE YET PRUDENT: Bloomberg described the new plan as “cautious”, stating that it “frustrat[es] hopes for tighter policy that would drive the nation to peak carbon emissions well before president Xi Jinping’s 2030 deadline”. Carbon Brief has just published an in-depth analysis of the plan. China Daily reported that the strategy “highlights measures to promote the climate targets of peaking carbon dioxide emissions before 2030”, which China said it would work towards “actively yet prudently”.
Around the world
- EU RULES: The European Commission has proposed new “made in Europe” rules to support domestic low-carbon industries, “against fierce competition from China”, reported Agence France-Presse. Carbon Brief examined what it means for climate efforts.
- RECORD HEAT: The US National Oceanic and Atmospheric Administration has said there is a 50-60% chance that the El Niño weather pattern could return this year, amplifying the effect of global warming and potentially driving temperatures to “record highs”, according to Euronews.
- FLAGSHIP FUND: The African Development Bank’s “flagship clean energy fund” plans to more than double its financing to $2.5bn for African renewables over the next two years, reported the Associated Press.
- NO WITHDRAWAL: Vanuatu has defied US efforts to force the Pacific-island nation to drop a UN draft resolution calling on the world to implement a landmark International Court of Justice (ICJ) ruling on climate, according to the Guardian.
