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.”

Revealed: Scientists tell Colombia fossil-fuel transition summit to ‘halt new expansion’
Countries attending a first-of-its-kind fossil-fuel summit have been asked to consider “action recommendations” such as “halting all new fossil-fuel expansion” and “reject[ing] gas as a bridging fuel”, according to a preliminary scientific report seen by Carbon Brief.
Around 50 nations will gather in Santa Marta, Colombia from 24-29 April to debate ways to “transition away” from fossil fuels, in the face of worsening climate change and sky-high oil prices.
The talks come after a large group of nations campaigned for, but ultimately failed, to get all countries to formally agree to a “roadmap” away from fossil fuels at the COP30 climate summit in Brazil in November.
The nations gathering in Santa Marta for the summit co-hosted by Colombia and the Netherlands, call themselves the “coalition of the willing”.
Ahead of country officials arriving in Santa Marta, a global group of academics will gather in the city this week to present and discuss the latest scientific evidence on fossil-fuel phaseout, which will then inform debate among policymakers.
A preliminary scientific “synthesis report” circulated to governments attending the talks and seen by Carbon Brief offers 12 “action insights” for countries to consider, along with a wide range of “action recommendations”.
These recommendations range from “phase out subsidies on fossil-fuel production and consumption” to “kick-start a forum to develop a legal framework to ban fossil-fuel advertisements”.
‘Rapid’ assessment
The preliminary scientific report seen by Carbon Brief – titled, “Action insights for the Santa Marta process” – is the result of some rapid work by an “ad-hoc” group of around 24 scientists.
It is designed to present governments attending the talks with concrete and actionable recommendations for transitioning away from fossil fuels.
The preliminary version, which includes recommendations such as “halting all new fossil fuel expansion”, has already been circulated to governments, with a view that this could help them to prepare for the talks in advance.
It will be further debated and refined by scientists attending the academic segment of the Santa Marta talks, before a final version is made public towards the end of April, Carbon Brief understands.
The process to produce the report began shortly after the conclusion of the COP30 climate summit in Brazil in November, explains its lead author, Dr Friedrich Bohn, a research scientist and co-founder of the Earth Resilience Institute in Germany. He tells Carbon Brief:
“When [Brazil] announced there would be a Santa Marta conference led by Colombia and the Netherlands, I was sitting listening with a small group of scientists. We thought: ‘This is great news, but it should be supported by scientific expertise.’”
One of the members of Bohn’s group had a pre-existing relationship with the Colombian government, allowing a dialogue to quickly be established, he continues:
“In the beginning, the idea was to just write a peer-reviewed paper. But, because of this close connection to the Colombian government and some feedback from them, the synthesis paper evolved.”
The report came out of a “very rapidly evolved process” that relied on the “goodwill” and “enthusiasm” of the academics involved, adds coordinating author Prof Frank Jotzo, a professor of climate change economics at Australian National University. (Jotzo is a former Carbon Brief contributing editor.) He tells Carbon Brief:
“It’s an attempt to get broad coverage on relevant topics from researchers with good expertise and reputation.”
The group of 24 scientists involved spent around two months compiling the “action insights” for the report, drawing on their expertise and the latest available research, says Jotzo.
Given the rapid nature of the report, it does not aim to be “completist”, has not been externally reviewed and did not follow a stringent process for author selection comparable to that used by Intergovernmental Panel on Climate Change (IPCC) reports, he adds.
The contributors to the report currently skew to the global north and include more men than women, adds Bohn.
‘Direct guidance’
In a departure from IPCC reports, the preliminary Santa Marta synthesis report offers “very direct guidance to action”, says Jotzo.
The report lists 12 “action insights”, each with three “action recommendations”. (The list was cut down from a shortlist of about 40-50 insights, Carbon Brief understands.)
One of the most striking in the draft is “action insight 5”, which says:
“Take immediate measures to prevent future emissions. Ban new fossil infrastructure, mandate deep methane cuts, accelerate electrification and inscribe fossil-fuel phase-down targets in NDCs [nationally determined contributions] and clean-energy pathways support to low and middle income countries (LMICs).”
The accompanying three “action recommendations” include “halting all new fossil-fuel extraction and infrastructure projects ahead of a final investment decision”, “implementing deep, legally binding methane cuts in the energy sector” and “inscrib[ing] targets for fossil-fuel phase down, electrification and green exports in NDCs”.
(The draft report includes multiple references to “phasing out” and “phasing down” fossil fuels, rather than the “transition away from fossil fuels” language that was, ultimately, agreed by countries at the COP28 UN climate talks in Dubai in 2023.)
Another action insight says “public support for climate action is broadly underestimated and undermined by interest groups, but it can be strengthened by debunking greenwashing narratives”.
One recommendation for this insight is that nations “reject natural gas as a bridging technology and CCS [carbon capture and storage] techniques as scalable compensation”.
In a letter introducing the report to governments and civil society, the scientists note that making direct recommendations is a “challenge for our community”, but added:
“However, in the spirit of a constructive collaboration between science and policymaking, we allowed ourselves to identify some potential courses of action that our community would recommend for each particular issue – and we invite you to weigh these against your own circumstances and pick up whatever seems most useful for you and your colleagues.”
The prescriptiveness of the recommendations – something strictly prohibited in IPCC reports – was an explicit request from the Colombian government, Bohn says:
“The idea of actionable recommendations was introduced by the Colombian government.
“There was some discussion within the team about this. It’s a tricky area when you leave science and move to consultation. Therefore, we agreed, in the end, to call them ‘actionable recommendations’ and to make them as precise as possible, from the scientific perspective.”
Jotzo, a veteran of the IPCC process, tells Carbon Brief that it was “very liberating” to work on a report with a “free-form process”:
“The bulk of policy-related research is very readily deployed to recommendations pointing out what countries could do. The IPCC process, for example, just doesn’t allow that. As far as the summary for policymakers in the IPCC is concerned, it will usually be governments that filter out anything that could be interpreted as a specific recommendation.”
He adds that the hope is that some of the action insights might be reflected in the high-level segment of the Santa Marta conference:
“No one is under any illusions that governments will walk away from the Santa Marta conference and will have made a decision to implement recommendations one, seven and nine – or something like that. But it is a chance to insert directly applicable action points into national and plurilateral policy agendas.”
Colombia calling
The preliminary report will be further debated and refined by scientists attending the “pre-academic segment” of the Santa Marta talks.
This is taking place from 24-26 April, ahead of the “high-level segment” involving ministers and other policymakers from 28-29 April.
The pre-academic segment will also separately see the launch of a new advisory panel on fossil-fuel transition and a scientifically led roadmap for how Colombia can transition away from fossil fuels, Carbon Brief understands.
The high-level segment is expected to be attended by representatives from around 50 countries, including COP31 host Turkey and major oil-and-gas producers such as the UK, Canada, Australia, Brazil and Norway.
Countries expected to attend account for one-third of global fossil-fuel demand and one-fifth of global production, according to the Colombian government.
At the end of the conference, countries are due to release a report featuring a “menu of solutions” for transitioning away from fossil fuels, according to Colombia’s environment minister Irene Vélez Torres.
This report is in turn set to inform a global “roadmap” on transitioning away from fossil fuels being developed by the Brazilian COP30 presidency, which is due to be presented at COP31 in Turkey this November.
The Brazilian COP30 presidency offered to bring forward a “voluntary” fossil-fuel transition “roadmap” outside of the official COP process, after countries failed to formally agree to one during negotiations in Belém.

Technical Assessment of Woodside’s Browse Pygmy Blue Whale Management Plan
To secure their approvals, Woodside had to develop a plan for how they would manage the significant risks to threatened green turtles if the project proceeds. We’ve had two independent scientists provide a technical assessment of Woodside’s management plan for whales and turtles and their findings are gobsmacking.
Woodside’s Browse gas project could make Scott Reef’s unique green turtles extinct.
