Wind and solar are growing faster than any other sources of electricity in history, according to new analysis from thinktank Ember.
It says they are now growing fast enough to exceed rising demand, meaning there will be a peak in fossil fuel electricity generation – and emissions – from this year.
As a result, Ember says in its latest annual review of global electricity data that a “new era of falling fossil fuel generation is imminent”.
Renewables met a record 30% of global electricity demand in 2023 and emissions from the sector would already have peaked if not for a record fall in hydropower, the analysis says.
The rise of wind and solar has been stemming the growth of fossil fuel power, which would have been 22% higher in 2023 without them, Ember says. This would have added around 4bn tonnes of carbon dioxide (GtCO2) to annual global emissions.
Nevertheless, the growth of clean electricity sources needs to accelerate to meet the global goal of tripling renewables by 2030, Ember says.
Meeting this goal would almost halve power sector emissions by the end of the decade, and put the world on a pathway aligned with the 1.5C climate target set in the Paris Agreement.
Clean capacity expansion
In 2023, more than twice as much new electricity generation from solar was added around the world as from coal, Ember says.
The share of solar within the global energy mix reached 5.5%, up from 4.6% in 2022, according to Ember. The share of wind stayed steady at 7.8% (2,304 terawatt hours, TWh).
No other sources of electricity generation have ever grown from 100TWh per year to 1,000TWh faster than solar and wind, Ember says. These took just eight and 12 years respectively, as shown in the figure below.
This sits far ahead of gas generation at 28 years, coal at 32 years and hydropower at 39 years. (Nuclear also grew from 100TWh to 1,000TWh over 12 years, the Ember figure shows, but tailed off more quickly than wind).
In response to Ember’s report, Dr Hannah Ritchie, deputy editor at Our World in Data, says in a statement:
“The main headline from Ember’s 2023 review is that the world sees a bright future for solar power. It is consistently breaking records and maintains its position as the fastest-growing power source in history. This is not only driven by the need to move to clean energy, but by its exciting economics as prices continue to fall. There are early signs that a peak in power sector emissions is imminent. Faster growth in low-carbon energy will be needed to drive down emissions quickly, especially as countries electrify transport, heating and industry.”
Despite solar and wind capacity growth in 2023, generation grew more slowly than expected, rising by 513TWh – a small drop from the 517TWh added in 2022.
Solar generation growth lagged behind record high capacity addition growth of 36%, due to lower sunlight levels in 2023, especially in China, as well as underreporting of solar generation in some countries. This is expected to be temporary, notes Ember.
For wind, there was a fall in generation for the first time since 2001, down 9.1TWh or 2.1%. Low wind conditions kept load factors close to their lowest level in five years, Ember says.
Additionally, higher costs slowed wind capacity additions as developers were forced to delay or cancel projects. More than $30bn in investment was put on hold as at least 10 offshore wind projects in the US and Europe were hit by delays, the Wall Street Journal reported for example.
In other renewables, hydropower’s share of the electricity mix fell by 0.6 percentage points to 14.3% of the world’s electricity mix, Ember reports. It therefore remains the world’s largest source of clean power, but its share of the mix is now at the lowest since at least 2000, with wind and solar combined sitting just 1 percentage point behind at 13.4% (3,935TWh) .
This is despite 7GW of new hydropower capacity coming online in 2023, according to the International Renewable Energy Agency (IRENA).
Ember had previously estimated that there would be a 0.4% reduction in global power sector emissions in 2023, but the fall in hydropower generation prevented this. Instead, emissions from the power sector rose by 1%, as the hydro shortfall was mostly met by coal.
Wind and solar have expanded from 0.2% of the global electricity mix in 2000 to 13.4% in 2023. Over the last year, their share grew by another 1.5 percentage points, up from 11.9% in 2022.
Demand rises to a record high
While wind and solar were rising fast, 2023 also saw global electricity demand reaching a record high, with an increase in demand of 627TWh, Ember reports. This is the equivalent of adding the entire demand of Canada (607TWh), for example.
With wind and solar having grown by 513TWh in 2023 and nuclear by 46TWh, but hydro falling 88TWh, the remaining demand growth was met by increased fossil fuel use.
This continued the trend of recent years where the gap between clean power growth and rapidly-rising demand was met by expanded electricity generation from fossil fuels.
Moreover, last year’s increase in demand was below the recent average, rising by 2.2%. This was due to a pronounced decrease in demand from OECD countries, including the US (-1.4%) and the European Union (-3.4%).
Elsewhere, there was rapid growth in electricity demand in China, growing nearly 7%. This was the equivalent of the total global demand growth in 2023, Ember notes.
Looking ahead, demand is likely to grow even faster as energy use is increasingly electrified. Already more than half of global electricity demand growth in 2023 was driven by the rise of electric vehicles (EVs), heat pumps, electrolysers, air conditioning and data centres, the report states.
According to the International Energy Agency (IEA), nearly 14m EVs were registered globally in 2023, bringing the total number on the roads to 40m. This puts electric car sales last year at 3.5m higher than in 2022, a 35% year-on-year increase.
Ember forecasts that electricity demand will accelerate significantly going forwards, with a growth of 968TWh expected in 2024. Even faster growth would be expected on a path to staying below 1.5C under the IEA’s “NZE” scenario, it notes.
Yet clean electricity generation is expected to grow faster still, with wind,solar and other clean energy sources adding an estimated 1,300TWh in 2024, as shown in the chart below.
This would be more than double the increase in 2023 (493TWh), due to an expected uplift in the US from the Inflation Reduction Act and a reversal in short-term factors such as last year’s hydro drought, the report says.
As a result of this, Ember estimates that fossil generation will decline by 333TWh or 2% in 2024. Even more importantly, Ember says clean energy growth makes ongoing falls in power sector fossil fuel use “inevitable” – meaning a steady decline in related emissions.
Christiana Figueres, former executive secretary of United Nations Framework Convention on Climate Change and founding partner of Global Optimism, says in a press statement:
“The fossil fuel era has reached its necessary and inevitable expiration date as these findings show so clearly. This is a critical turning point: Last century’s outdated technologies can no longer compete with the exponential innovations and declining cost curves in renewable energy and storage. All of humanity and the planet upon which we depend will be better off for it.”
Tripling renewables and what comes next
At the COP28 UN climate conference in Dubai in 2023, all countries agreed to contribute to the tripling of global renewable energy capacity by 2030, in what was seen as a “crucial” step for 1.5C.
Although the COP28 outcome did not include numerical targets, Ember says tripling renewables would mean adding 14,000TWh of annual renewable generation by 2030, compared to 2022 levels. In 2022, renewables accounted for 8,599TWh of the 28,844TWh of electricity generated globally.
After accounting for rising electricity demand, it says this tripling would help cut fossil fuel generation by 6,570TWh, or 37%. With highly-polluting coal power bearing the brunt of this reduction, power sector emissions would fall even faster, by 45% in 2030, it says.
Already, the expansion of renewable energy has slowed fossil fuel growth substantially, as the graph below shows.
After recording average annual growth of 3.5% over the decade 2004-2013, fossil fuel generation only grew by an average of 1.3% in the decade to 2023.
Fossil fuel generation was 22% lower in 2023 than it would have been without solar and wind generation. Between 2015 and 2023, wind and solar have together avoided more than 4GtCO2 emissions, Ember notes.
Meeting the tripling goal would mean some 60% of global electricity supplies coming from renewable sources by 2030.
This would mark a dramatic shift from current renewable shares. In 2023, 102 countries had a renewable generation share of 30% or higher, up from 98 in 2022. Yet only 69 countries in 2023 had a share in excess of 50%.
Hitting the tripling target would help put “the world on a pathway aligned with the 1.5C climate goal”, says Ember.
Ember’s director of global insights, Dave Jones says in a statement:
“We already know the key enablers that help countries unleash the full potential of solar and wind. There’s an unprecedented opportunity for countries that choose to be at the forefront of the clean energy future.”

Wind and solar are ‘fastest-growing electricity sources in history’
It’s been less than 20 years since baby food in plastic pouches first appeared on supermarket shelves. Since then, these convenient and popular “squeeze-and-suck” products have become the dominant packaging for baby food, transforming the way that millions of babies are fed around the world. But emerging evidence raises concerns that big food brands are feeding our children plastic pollution with unknown consequences, by selling baby food in flexible plastic packaging.
Testing commissioned by Greenpeace International in 2025 found plastic particles in the baby food products of two global consumer goods companies – Danone and Nestlé. The study suggests a link between the type of plastic the pouches are lined with – polyethylene – and some of the microplastics found. Tests also suggest a range of plastic-associated chemicals in the packaging and food of both products.

U.N. General Assembly Embraces Court Opinion That Says Nations Have a Legal Obligation to Take Climate Action
The U.S. was among eight countries that voted against endorsing the nonbinding ruling that said all nations must take steps to limit temperature rise to 1.5 degrees Celsius.
The United Nations General Assembly on Wednesday voted overwhelmingly in favor of a climate justice resolution championed by the small Pacific Island nation of Vanuatu. The resolution welcomes the historic advisory opinion on climate change issued by the International Court of Justice in July 2025 and calls upon U.N. member states to act upon the court’s unanimous guidance, which clarified that addressing the climate crisis is not optional but rather is a legal duty under multiple sources of international law.
The number of new coal-fired power plants built around the world hit a “10-year high” in 2025, even as the global coal fleet generated less electricity, amid a “widening disconnect” in the sector.
That is according to the latest annual report from Global Energy Monitor (GEM), which finds that the world added nearly 100 gigawatts (GW) of new coal-power capacity in 2025, the equivalent of roughly 100 large coal plants.
It adds that 95% of the new coal plants were built in India and China.
Yet GEM says that the amount of electricity generated with coal fell by 0.6% in 2025 – with sharp drops in both China and India – as the fuel was displaced by record wind and solar output, among other factors.
The report notes that there have been previous dips in output from coal power and there could still be ups – as well as downs – in the near term.
For example, nearly 70% of the coal-fired units scheduled to retire globally in 2025 did not do so, due to postponements triggered by the 2022 energy crisis and policy shifts in the US.
However, GEM says that the underlying dynamics for coal power have now fundamentally shifted, as the cost of renewables has fallen and low usage hits coal profitability.
China and India dominate growth
In 2025, coal-capacity growth hit a 10-year high, with 97 gigawatts (GW) of new power plants being added, according to GEM.
(Capacity refers to the potential maximum power output, as measured in GW, whereas generation refers to power actually generated by the assets over a period of time, measured in gigawatt hours, GWh.)
This is the highest level since 2015 when 107GW began operating, as shown in the chart below. This makes 2025 the second-highest level of additions on record.
The majority of this growth came from China and India, which added 78GW and 10GW, respectively, against 9GW from all other countries.
Yet GEM points out that, even as coal capacity in China grew by 6%, the output from coal-fired power plants actually fell 1.2%. This means that each power plant would have been running less often, eroding its profitability. Similarly, capacity in India grew by 3.8%, while generation fell by 2.9%.
China and India had accounted for 87% of new coal-power capacity that came into operation in the first half of 2025. The shift up to 95% in the year as a whole highlights how increasingly just those two countries dominate the sector, GEM says.
Christine Shearer, project manager of GEM’s global coal plant tracker, said in a statement:
“In 2025, the world built more coal and used it less. Development has grown more concentrated, too – 95% of coal plant construction is now in China and India, and even they are building solar and wind fast enough to displace it.”
Both China and India saw solar and wind meet most or all of the growth in electricity demand last year.
Analysis for Carbon Brief last year showed that, in the first six months of 2025 alone, a record 212GW of solar was added in China, helping to make it the nation’s single-largest source of clean-power generation, for example.
However, the country continues to propose new coal plants. In 2025, a record 162GW of capacity was newly proposed for development or reactivated, according to GEM. This brought the overall capacity under development in the country to more than 500GW.
China’s 15th “five-year plan”, covering 2026-2030, had pledged to “promote the peaking” of coal use, while a more recent pair of policies introduced stricter controls on local governments’ coal use.
For its part, in India some 28GW of new coal capacity was newly proposed or reactivated last year, bringing the total under development to 107.3GW and under-construction capacity to 23.5GW.
The Indian government is planning to complete 85GW of new coal capacity in the next seven years, even as clean-energy expansion reaches levels that could cover all of the growth in electricity demand.
Outside of China and India, GEM says that just 32 countries have new coal plants under construction or under development, down from 38 in 2024.
Countries that have dropped plans for new coal in 2025 include South Korea, Brazil and Honduras, it says. GEM notes that the latter two mean that Latin America is now free from any new coal-power proposals.
This means that both electricity generation from coal and the construction of new coal-fired power plants are increasingly concentrated in just a few countries, as the chart below shows.
Indonesia’s coal fleet grew by 7% in 2025 to 61GW, with a quarter of the new capacity tied to nickel and aluminium processing, according to GEM.
Turkey – which is gearing up to host the COP31 international climate summit in November – has just one coal-plant proposal remaining, down from 70 in 2015.
The amount of new coal capacity that started to operate in south-east Asia fell for the third year in a row in 2025, according to GEM.
Countries in south Asia that rely on imported energy are increasingly looking to other technologies to protect themselves from fossil-fuel shocks, such as Pakistan, which is rapidly deploying solar, states the GEM report.
In Africa, plans for new coal capacity are concentrated in Zimbabwe and Zambia, the report shows, with the two countries accounting for two-thirds of planned development in the region.
‘Persistence of policies’
While new coal plants are still being built and even more are under development, GEM notes that the global electricity system is undergoing rapid changes.
Crucially, the growth of cheap renewable energy means that new coal plants do not automatically translate into higher electricity generation from coal.
Without rising output from coal power, building new plants simply results in the coal fleet running less often, further eroding its economics relative to wind and solar power.
Indeed, GEM notes that electricity generation from coal fell globally in 2025. Moreover, a recent report by thinktank Ember found that renewable energy overtook coal in 2025 to become the world’s largest source of electricity.
GEM notes that coal generation may fluctuate in the near term, in particular due to potential increases in demand driven by higher gas prices.
It adds that gas price shocks, such as the one triggered by the Iran war, can cause temporary reversals in the longer-term shift away from coal.
According to Carbon Brief analysis, at least eight countries announced plans to either increase their coal use or review plans to transition away from coal in the first month of the Iran war. However, a much-discussed “return to coal” is expected to be limited.
GEM’s report highlights that global fossil-fuel shocks can have an impact on the phase out of coal capacity over several years.
In the EU, for example, 69% of planned retirements did not take place in 2025, due to postponements that began in the 2022-23 energy crisis triggered by the Russian invasion of Ukraine, according to the report. Countries across the bloc chose to retain their coal capacity amid gas supply disruptions and concerns about energy security.
Yet coal-fired power generation in the bloc is now more than 40% below 2022 levels. Again, this highlights that coal capacity does not necessarily translate into electricity generation from coal, with its associated CO2 emissions.
Overall, GEM notes that “repeated exposure to fossil-fuel price volatility is as likely to accelerate the shift toward clean energy as it is to delay it”.
GEM’s Shearer says in a statement:
“The central challenge heading into 2026 is not the availability of alternatives, but the persistence of policies that treat coal as necessary even as power systems move increasingly beyond it.”
In the US, 59% of planned retirements in 2025 did not happen, according to GEM. This was due to government intervention to keep ageing coal plants online.
Five coal-power plants have been told to remain online through federal “emergency” orders, for example, even as the coal fleet continues to face declining competitiveness.
Keeping these plants online has cost hundreds of millions of dollars and helped drive an annual increase in the average US household electricity prices of 7%, according to GEM.
Despite such measures, Trump has overseen a larger fall in coal-fired power capacity than any other US president, according to Carbon Brief analysis.
Meanwhile, according to new figures from the US Energy Information Administration, solar and wind both set new records for energy production in 2025.
Despite challenges with policy and wider fossil-fuel impacts, the underlying dynamic has shifted, says GEM, as “clean energy becomes more competitive and widely deployed” around the world.
It adds that this raises the prospect of “a more sustained decoupling between coal-capacity growth and generation, particularly if clean-energy deployment continues at current rates”.
