2024年5月,尽管用电需求持续增长,清洁能源发电量占到中国全国总发电量的44%,创下历史新高;燃煤发电量占比降至53%,达到历史低点。

基于官方数据和其他数据,Carbon Brief 的新分析揭示了煤炭在能源结构中占比下降的真实程度。

2023年5月,煤炭在中国发电量中所占比例为60%。一年后,这一数字下降了7个百分点。

该分析揭示的其他关键信息包括:

  • 国家统计局按发电方式分列的月度发电量数据现在对风能和太阳能发电量计入非常有局限性。例如,它未纳入“分布式”屋顶光伏和较小的集中式太阳能发电站,因此只能捕捉到约一半的太阳能发电量。
  • 国家统计局的月度总发电量为718太瓦时(TWh),而国家能源局报告提出月度电力需求为775太瓦时,两者的差距显著。实际上,由于发电厂和电网损耗,发电量肯定应高于需求量。
  • 媒体报道曾猜测,创纪录的新增可再生能源装机容量会在5月份触及电网上限,但新数据显示情况并非如此。
  • 2024年5月,中国电力需求同比增长49太瓦时(7.2%)。
  • 与此同时,清洁能源发电量创纪录地增长了78太瓦时,其中太阳能发电量创纪录地增长了41太瓦时(78%),水力发电量从早些时候干旱造成的低点回升了34太瓦时(39%),风力发电量小幅增长了4太瓦时(5%)。
  • 随着清洁能源的增长超过电力需求增长,化石燃料发电量被迫回落,出现了自2019年新冠大流行以来最大的月度降幅。天然气发电量下降了4太瓦时(16%),燃煤发电量下降了16太瓦时(4%)。
  • 化石燃料发电量的下降意味着电力行业的CO2排放量下降了3.6%,而电力行业的CO2排放量约占中国温室气体排放总量的五分之二,是近年来排放增长的主要来源。

从2024年3月开始,中国化石燃料和水泥行业的CO2排放量由增变减。新的研究结果表明,这一趋势仍在继续。

如果目前风能和太阳能的快速部署得以继续,那么中国的CO2排放量很可能会继续下降,从而使2023年成为中国碳达峰的一年。

月度数据差异

国家统计局每月都会公布中国按发电方式分列的发电量数据。2024年5月的数据是在近一个月前的6月中旬公布,并被广泛报道。

然而,这些数据的局限性越来越大,因为其中不包括“分布式”光伏电站,如家庭和企业屋顶上安装的光伏系统。本文的分析表明,这使得大约一半的太阳能发电总量被遗漏。

如果仔细审视用电量,国家统计局发电量数据不完整这一事实显而易见:国家能源局报告的5月份用电量为775太瓦时,而国家统计局报告的发电量仅为718太瓦时。实际上,由于发电厂和输电过程中的损耗,发电量肯定远远大于用电量。

国家统计局报告的太阳能和风能发电量似乎很少,这引起了人们的困惑,并导致有报道声称中国的风能和太阳能发电表现不佳。

中电联收集的“利用率”数据可跟踪风能和太阳能发电的表现,显示相对于最大潜力的实际出力。这些数据通常包含在国家能源局发布的月度统计数据中。

国家能源局因在5月份发布的数据中略过了利用率,这导致彭博社和路透社猜测背后原因可能是风能和太阳能数据不佳。这一猜测在中电联直接提供其数据后基本被证明不成立,因为太阳能发电利用率大幅上升;风能利用率虽然下降,但在正常的年度变化范围内。

另一个数据集追踪了由于电网灵活性低而浪费的太阳能和风能发电量的比例,结果显示两者分别小幅增长了0.8和1.7个百分点。这对电厂运营者来说是个问题,但该升幅远未达到会显著影响利用率的程度——消纳率的年际变化幅度通常超过5%。

现在有足够的数据来破解国家统计局发电数据的局限性,并描绘出中国5月份发电结构的全貌。

首先值得一提的是,国家统计局的数据是以30天为一个月进行归一化处理的,这造成了部分数据不匹配。本文剩余部分使用归一化后的30天数据。

除了使用国家统计局数据,还可根据报告的装机容量和利用率来估算太阳能和风能发电量。通过将这些估计值与其他技术的报告发电量相结合,得出总发电量为783太瓦时,同比增长8%。

报告的750太瓦时用电量(按30天为一个月进行归一化)与估计的783太瓦时发电量相符,另有4.2%的差异是由于传输损耗造成的。

目前尚无输电损耗的月度数据,但2023年的平均值为4.5%,与报告的用电量和预估发电量之间的差距非常吻合。

创纪录的结果

综合各种数据可以看出,2024年5月太阳能发电量创纪录地增长了78%,远高于不完整的国家统计局数据中29%的同比增幅。

太阳能发电装机容量增加52%至691吉瓦(gigawatt),产能利用率从16%提高到19%,太阳能发电量从2023年5月的53太瓦时增至2024年5月的94太瓦时,增加了41太瓦时,创下中国各发电方式发电量中最大的增幅。

水电发电量的增幅位居第二,虽然发电量仅增长了1%,但利用率却从31%跃升至41%,因为该行业正从2022年至2023年创纪录的干旱中恢复过来。这使得水电发电量增加了39%(34太瓦时),达到115太瓦时。

风电装机大幅增长了21%,但其利用率却有所下降,这可能是由于风力条件逐月变化所致。因此,发电量的增幅相对较小,仅为5%(4太瓦时),达到83太瓦时。核电和生物质发电的发电量也有小幅增长,但核电站的利用率从87%下降到85%。

如下图所示,清洁能源发电量总计增长了78太瓦时。这足以超过49太瓦时的需求增长。

因此,尽管燃气发电装机增加了9%,但发电量却大幅下降16%,利用率急剧下降了24%。燃煤发电装机增加了3%,但发电量却下降了3.7%,平均利用率下降了7%。需求下降可能会抑制过去两年火热的对新建煤炭产能的投资。

燃煤和燃气发电量的变化,加之燃煤电厂热耗率的轻微下降,意味着电力行业的CO2排放量下降了3.6%。

在发电量发生上述变化后,中国的发电结构在2024年5月已大幅减少了对化石燃料的依赖。如下图所示,燃煤发电份额从去年同期的60%降至53%,是有记录以来的最低份额。

与此同时,太阳能发电占比从去年同期的7%上升到12%,创历史最高纪录。其余为风电(11%)、水电(15%)、核电(5%)、天然气发电(3%)和生物质发电(2%)。

非化石能源的总体份额达到创纪录的44%,间歇性可再生能源(太阳能和风能)的比例也创下新高,达到23%。

如上图所示,尽管需求不断增长,但太阳能和风能在中国电力结构中的份额正在迅速增加。2016年5月,它们仅占总量的7%。

与此同时,2024年5月,清洁能源发电装机继续强劲增长,新增太阳能发电装机19吉瓦 ,风电3吉瓦 ,核电1.2吉瓦。

在2024年的前五个月,中国新增了约79吉瓦的太阳能和20吉瓦的风能。如下图所示,这两个新增发电装机数字比去年分别增长了29%和21%,而去年的数字已经创下历史新高。

就太阳能发电具体而言,2024年5月的月新增装机高于4月,与2023年5月相比也有同比增长。

太阳能发电量的快速增长表明,太阳能产能的激增正在提供新的电力供应,其规模足以满足中国大部分的需求增长。

这进一步印证了中国的CO2排放量正处于结构性下降时期的观点。

如果清洁能源的新增装机保持在2023年和2024年初的水平,那么CO2排放量可能会持续下降,这将确定2023年是中国实现碳达峰的一年。

由于中国将在明年初宣布新的气候目标,政府对清洁能源增长的雄心水平仍有待观察。

关于数据

风能和太阳能发电量,以及按燃料划分的火电发电量系通过将每月末的发电装机乘月利用率计算得出,数据来自万得金融终端提供的中电联报告数据。

火电、水电和核电的总发电量来源于国家统计局的月度发布数据。由于无法获得生物质发电的月度利用率数据,因此采用2023年的年平均利用率52%。

发电产生的碳排放量估算基于中国最新的2018年国家温室气体排放清单中的排放因子,以及国家能源局公布的燃煤电厂月平均热耗率,并假设燃气电厂平均热耗率为50%。

Analysis: EVs just outsold petrol cars in EU for first time ever

Published

on

Sales of electric vehicles (EVs) overtook petrol cars in the EU for the first time in December 2025, according to new figures released by industry group the European Automobile Manufacturers’ Association (ACEA).

The figures show that registrations of battery EVs – sometimes referred to as BEVs, or “pure EVs” – reached 217,898, up 51% year-on-year from December 2024, as shown in the chart below.

Meanwhile, sales of petrol cars in the bloc fell 19% year-on-year, from 267,834 in December 2024 to 216,492 in December 2025.

Overall in 2025, EVs reached 17.4% of the market share in the bloc, up from 13.6% the previous year.

(EVs run purely from a battery that is charged from an external source, plug-in hybrids have both a battery that can be charged and an internal combustion engine, whilst regular hybrids cannot be plugged in, they have a smaller battery that is charged from the engine or braking.)

According to ACEA, 1,880,370 new battery-electric cars were registered last year, with the four biggest markets – Germany (+43.2%), the Netherlands (+18.1%), Belgium (+12.6%), and France (+12.5%) – accounting for 62% of registrations.

In a release setting out the figures, ACEA described this as “still a level that leaves room for growth to stay on track with the transition”.

Meanwhile, registrations of petrol cars fell by 18.7% across 2025, with all major markets seeing a decrease.

France accounted for the steepest decline in petrol registrations at 32% year-on-year, followed by Germany (-21.6%), Italy (-18.2%), and Spain (-16%).

Overall, 2,880,298 new petrol cars were registered in 2025, a drop in market share from 33.3% in December 2024 to 26.6%.

Hybrid vehicles, which are entirely fuelled by petrol or diesel, remain the largest segment of the EU car market, with sales jumping 5.8% from 307,001 in December 2024 to 324,799 a year later, as shown in the chart below.

However, cars that can run on electricity – battery EVs and plug-in hybrids – are growing even faster, with sales up 51% and 36.7% in December 2025, respectively.

The registration figures follow the EU’s automotive package, released in December to “support the automotive sector’s efforts in the transition to clean mobility”.

It includes a proposed shift from banning the sale of new combustion-engine cars from 2035 to reducing their tailpipe emissions.

Under the proposals, the EU will target a 90% cut in carbon dioxide (CO2) emissions from 2021 levels by 2035, rather than all vehicle sales having to be zero-emissions.

If approved, the package would require that the remaining 10% of emissions be compensated through the use of low-carbon steel made in the EU or from e-fuels and biofuels.

This would allow for plug-in hybrids (PHEVs), “range extenders”, hybrids and pure internal combustion engine vehicles to “still play a role beyond 2035”.

There has been repeated pushback from the automotive sector in Europe against the introduction of “clean car rules”, which has led to targets being shifted more than once.

For example, the head of Stellantis, one of the largest car manufacturers in Europe, recently claimed that there was no “natural” demand for EVs.

Automakers have argued that EU targets for cleaner cars should be eased in the face of competition from Chinese producers and US tariffs.

ACEA figures show Volkswagen continued to claim the largest market share in the EU, accounting for 26.7% of new registrations in December, up from 25.6% a year earlier.

It was followed by Stellantis, Renault, Hyundai, Toyota and BMW.

EV giant Tesla saw its market share drop from 3.5% in December 2024 to 2.2% in December 2025. Over the course of 2025, the brand saw its market share in the EU fall 37.9% from 2024, following controversy around its owner, Elon Musk.

Meanwhile, Chinese EV brand BYD tripled its market share from 0.7% in December 2024 to 1.9% in December 2025.

For proof of the energy transition’s resilience, look at what it’s up against

Published

on

Al-Karim Govindji is the global head of public affairs for energy systems at DNV, an independent assurance and risk management provider, operating in more than 100 countries.

Optimism that this year may be less eventful than those that have preceded it have already been dealt a big blow – and we’re just weeks into 2026. Events in Venezuela, protests in Iran and a potential diplomatic crisis over Greenland all spell a continuation of the unpredictability that has now become the norm.

As is so often the case, it is impossible to separate energy and the industry that provides it from the geopolitical incidents shaping the future. Increasingly we hear the phrase ‘the past is a foreign country’, but for those working in oil and gas, offshore wind, and everything in between, this sentiment rings truer every day. More than 10 years on from the signing of the Paris Agreement, the sector and the world around it is unrecognisable.

The decade has, to date, been defined by a gritty reality – geopolitical friction, trade barriers and shifting domestic priorities – and amidst policy reversals in major economies, it is tempting to conclude that the transition is stalling.

Truth, however, is so often found in the numbers – and DNV’s Energy Transition Outlook 2025 should act as a tonic for those feeling downhearted about the state of play.

While the transition is becoming more fragmented and slower than required, it is being propelled by a new, powerful logic found at the intersection between national energy security and unbeatable renewable economics.

A diverging global trajectory

The transition is no longer a single, uniform movement; rather, we are seeing a widening “execution gap” between mature technologies and those still finding their feet. Driven by China’s massive industrial scaling, solar PV, onshore wind and battery storage have reached a price point where they are virtually unstoppable.

These variable renewables are projected to account for 32% of global power by 2030, surging to over half of the world’s electricity by 2040. This shift signals the end of coal and gas dominance, with the fossil fuel share of the power sector expected to collapse from 59% today to just 4% by 2060.

    Conversely, technologies that require heavy subsidies or consistent long-term policy, the likes of hydrogen derivatives (ammonia and methanol), floating wind and carbon capture, are struggling to gain traction.

    Our forecast for hydrogen’s share in the 2050 energy mix has been downgraded from 4.8% to 3.5% over the last three years, as large-scale commercialisation for these “hard-to-abate” solutions is pushed back into the 2040s.

    Regional friction and the security paradigm

    Policy volatility remains a significant risk to transition timelines across the globe, most notably in North America. Recently we have seen the US pivot its policy to favour fossil fuel promotion, something that is only likely to increase under the current administration.

    Invariably this creates measurable drag, with our research suggesting the region will emit 500-1,000 Mt more CO₂ annually through 2050 than previously projected.

    China, conversely, continues to shatter energy transition records, installing over half of the world’s solar and 60% of its wind capacity.

    In Europe and Asia, energy policy is increasingly viewed through the lens of sovereignty; renewables are no longer just ‘green’, they are ‘domestic’, ‘indigenous’, ‘homegrown’. They offer a way to reduce reliance on volatile international fuel markets and protect industrial competitiveness.

    Grids and the AI variable

    As we move toward a future where electricity’s share of energy demand doubles to 43% by 2060, we are hitting a physical wall, namely the power grid.

    In Europe, this ‘gridlock’ is already a much-discussed issue and without faster infrastructure expansion, wind and solar deployment will be constrained by 8% and 16% respectively by 2035.

    Comment: To break its coal habit, China should look to California’s progress on batteries

    This pressure is compounded by the rise of Artificial Intelligence (AI). While AI will represent only 3% of global electricity use by 2040, its concentration in North American data centres means it will consume a staggering 12% of the region’s power demand.

    This localized hunger for power threatens to slow the retirement of fossil fuel plants as utilities struggle to meet surging base-load requirements.

    The offshore resurgence

    Despite recent headlines regarding supply chain inflation and project cancellations, the long-term outlook for offshore energy remains robust.

    We anticipate a strong resurgence post-2030 as costs stabilise and supply chains mature, positioning offshore wind as a central pillar of energy-secure systems.

    Governments defend clean energy transition as US snubs renewables agency

    A new trend is also emerging in behind-the-meter offshore power, where hybrid floating platforms that combine wind and solar will power subsea operations and maritime hubs, effectively bypassing grid bottlenecks while decarbonising oil and gas infrastructure.

    2.2C – a reality check

    Global CO₂ emissions are finally expected to have peaked in 2025, but the descent will be gradual.

    On our current path, the 1.5C carbon budget will be exhausted by 2029, leading the world toward 2.2C of warming by the end of the century.

    Still, the transition is not failing – but it is changing shape, moving away from a policy-led “green dream” toward a market-led “industrial reality”.

    For the ocean and energy sectors, the strategy for the next decade is clear. Scale the technologies that are winning today, aggressively unblock the infrastructure bottlenecks of tomorrow, and plan for a future that will, once again, look wholly different.
