Despite record additions, clean energy sources could not fully meet a surge in electricity demand in 2024, driven mainly by the effects of rising temperatures, an annual review by the International Energy Agency (IEA) showed on Monday.

Renewables and nuclear energy provided four-fifths of the rise in electricity generation, which increased by 4% last year – marking “a significant acceleration” from the average annual growth seen in the last 15 years, the IEA said. The rest of the growth was covered by coal – still the largest source in the total global electricity mix – and by an expanding supply of fossil gas power.

Record temperatures push up power demand

Soaring use of cooling technologies like air conditioning in response to extreme heat was a key factor in the growing appetite for electricity, especially in China and India, which are heavy users of coal power, the IEA said.

Last year was the hottest on record and the global average temperature for 2024 exceeded the Paris Agreement benchmark of 1.5C above pre-industrial levels for the first time.

Growing electricity consumption by industry, the rollout of electric vehicles and the expansion of data centres also drove power demand, the Paris-based watchdog said.

Fatih Birol, the IEA’s executive director, said in a briefing on Monday that “even though oil and gas will remain essential energy carriers, we hear the footsteps of the age of electricity coming”.

He also noted that demand for all major fuels and energy technologies rose in 2024 as a result of rapidly growing electricity use.

World uses more coal, gas and renewables

Power generation from solar panels and wind turbines increased at a record pace thanks to a rapid rate of new installations, while nuclear power output was boosted by new projects and the restarting of reactors in France and Japan, the report noted.

But electricity generation from fossil gas and coal kept growing and, overall, fossil fuels still represented 60% of the global electricity mix last year.



While almost all regions saw an acceleration in electricity consumption, China and Southeast Asia saw the fastest increases in 2024, according to the IEA report.

After a decline in 2023, advanced economies led by the United States saw a return to growth in electricity consumption driven by strong demand for cooling, growth in the data-centre sector and a pickup in industrial production.

China continued to lead global expansion of renewables, making up almost two-thirds of all
renewable capacity connected to the grid in 2024. The United States, India and Brazil also saw record levels of solar photovoltaic roll-outs last year.

But intense heatwaves pushed coal and gas use higher in both China and India, while the United States and Eurasia also saw strong increases in gas demand for electricity, the IEA report noted.

Energy-related emissions still rising

Rising gas and coal use fuelled a 0.8% increase in global carbon dioxide emissions generated by the energy sector in 2024, the IEA said – but trends varied widely across regions.

While energy-related emissions dipped in advanced economies, whose growth has become less polluting, the decline was outweighed by marked increases in emerging economies – especially India – and the international aviation sector.

Clean hydrogen hype fades as high costs dampen demand

Speaking to journalists, Laura Cozzi, the IEA’s director of sustainability, noted that planet-heating emissions could have been exponentially higher without the rapid adoption of clean technologies – a development that is keeping 2.6 gigatonnes of CO2 out of the atmosphere.

“Those are fossil fuels that are being displaced,” she said, adding that the transition is moving “very fast” in the electricity sector.

Paris Agreement committee names three countries snubbing it over NDCs

Published

on

Three countries have been named by the Paris Agreement’s compliance committee for failing to submit a nationally determined contribution (NDC) and repeatedly snubbing offers of help with their climate plans.

After months of internal debate over whether to identify serial non-responders, the Paris Agreement’s Implementation and Compliance Committee (PAICC) named the three countries which have failed to engage with it over their NDCs on Friday.

It named Democratic Republic of Congo, Senegal and North Korea in a footnote of its annual report, adding that it decided to name them “with a view to facilitating engagement”, adding that representatives of the three nations had been invited to its meeting in early 2027 “with the purpose of identifying any challenges and constraints”.

“The Committee noted the importance of Parties engaging with the Committee in a timely manner, while noting that some delays may be due to the national capabilities and circumstances of the Parties”, the report said.

    In July, PAICC said 12 countries had ignored its repeated attempts to discuss why they had not published an NDC as required every five years under the 2015 Paris accord.

    Members of the committee had been divided over whether to name them, but at a September meeting decided to do so in their annual report to the annual climate COP summit.

    By the time the report was published on Friday, only Congo, Senegal and North Korea “had not communicated an NDC or submitted a [Biennial Transparency Report] and had not yet responded to any of the Committee’s notifications, despite several reminders issued by the Committee in this regard”.

    Rainforest and renewable energy ambitions

    The silence from Congo and Senegal is notable because the former is home to much of the Congo Basin rainforest while the latter has sought billions of dollars in climate finance to support its renewable energy ambitions.

    After Brazil, Congo has more rainforest than any country in the world. This forest, and the country’s peatlands, absorb huge amounts of greenhouse gas but are fast being lost to expanding farmland, charcoal production, logging and mining.

    Senegal signed a Just Energy Transition Partnership with Canada and wealthy European nations in 2023, to help it meet its renewable energy targets under the-then government of Macky Sall. It was chair of the Least Developed Countries group between January 2022 and December 2023.

    Tejas Rao, who is researching the PAICC as part of a doctoral thesis at Cambridge University, said the governments of the three countries should engage with the committee.

    “Engagement costs these governments very little and the committee has shown it will listen,” he said.

    “Silence leaves the committee with no basis to help, and it leaves the [governments] exposed to the narrative that they are simply disengaged,” he told Climate Home News.

    Paris Agreement requirement

    The 2015 Paris Agreement requires all parties to publish an NDC every five years outlining their emissions reduction targets, with each plan meant to be more ambitious than the country’s last NDC.

    The latest set – the third round of plans, with new targets for 2035 – was due in February 2025. While most countries missed this deadline, all but around 30 – mostly small emitters but including Egypt, Vietnam and Argentina – have now submitted them.

    Over the year, the PAICC – which is made up of government climate officials from developed and developing countries – has been communicating with governments that have not submitted NDCs and trying to overcome barriers to them doing so.

    Some nations have cited exceptional circumstances as the reason for not submitting an NDC, a process that requires a significant amount of work in tracking emissions and consulting on how to curb them across the economy. For example, a letter from a Sudanese official to the PAICC, seen by Climate Home News, said that the country’s civil war had led to the suspension of its NDC preparation.

      The US and Iran are not signed up to the Paris Agreement and so do not have active NDCs, nor does Taiwan, which is not a UN member state.

      Rao said that because the PAICC is “facilitative and non-punitive”, naming the countries “is meant to open a door, not close one – the invited consultation is the point”.

      “In recent months, governments that explained their constraints, whether capacity, finance or domestic process, have been met with follow-up and support rather than sanction, and the number of silent governments has fallen sharply,” Rao said.

      Q&A: Why a pivotal IPCC meeting in Ethiopia ended in ‘profound disappointment’

      Article Contents

      Countries have failed – for the sixth time running – to agree on the timeline for publishing the Intergovernmental Panel on Climate Change’s (IPCC) next set of influential reports.

      The IPCC’s 65th session (IPCC-65) was seen by many to be the final opportunity for countries to agree on a schedule where its seventh assessment report (AR7) would be published in time for the UN’s second “global stocktake” of climate action.

      Before last week’s meeting in Addis Ababa, Ethiopia, IPCC chair Prof Sir Jim Skea had warned that releasing the reports in time for the stocktake in 2028 would depend on a timelines being agreed by the end of 2026.

      But the week-long meeting descended into fraught disagreements between governments, resulting in Skea “suspending” the talks on Friday evening with no decision made.

      Countries were also unable to agree on the IPCC’s budget for the rest of the AR7 cycle, leaving the body with a “serious funding crisis”.

      The IPCC has pledged to reconvene the meeting at the “earliest opportunity”; however, it has not yet given an indication of when this will be.

      In his concluding remarks, Skea described the Addis Ababa summit as a “profound disappointment” and “among the most difficult IPCC meetings”, according to reporting from the Earth Negotiations Bulletin (ENB).

      Some countries have reacted with dismay to the breakdown of negotiations, warning that a failure to have the IPCC’s latest assessments on climate adaptation and mitigation ready for the UN stocktaking exercise would undermine global climate action.

      A climate envoy from a Pacific island state said it was a “travesty that a handful of countries continue to delay the IPCC’s reports – the science we need back home to help us save lives and livelihoods”.

      Below, Carbon Brief explores the key developments, debates and disagreements at the IPCC meeting.

      What timeline options were delegates debating?

      Top of the agenda during the Addis Ababa meeting was a decision on the timeline of the publication of AR7’s three working group reports – also known as the “work plan”. The three reports cover climate science (WG1), impacts and adaptation (WG2) and mitigation (WG3).

      Countries failed to reach a resolution on the scheduling of the influential reports at five consecutive IPCC meetings since 2024 – despite drafting being well underway.
