暴雨、洪水和热浪等极端天气事件被称为中国的“新常态”。

今年四月的暴雨和洪水导致中国损失近120亿元人民币(16.5亿美元),灾害损失“为近10年同期最重”。六月,中国约有33条河流“超过警戒水位”,数十人丧生。广西桂林遭遇自1998年以来最大洪水。

不到一年前,北京气象部门在2023年7月的短短五天内记录了745毫米的降雨量,几乎是该市往年整月的降雨量。

北京周边的河北省在同一时间也出现了强降雨。2023年7月,临城县的降雨量超过1米,是其年平均降雨量的两倍。

2021年7月,河北的邻省河南出现了“千年一遇”的暴雨。

虽然中国已经出台了更多政策来改善其应急系统和基础设施,但日益增多的极端天气事件仍继续带来挑战。

在本篇Q&A中,Carbon Brief将探讨中国近期洪灾的原因、中国如何适应洪灾,以及是否需要未雨绸缪、重新审视其防洪系统。

近期洪灾背后的原因是什么?

近年来频繁发生的暴雨和洪水背后有各种因素。

英国布里斯托尔大学地理科学学院名誉研究员奥利弗·温(Oliver Wing)博士告诉Carbon Brief:“总体而言,由于克劳修斯-克拉佩龙方程,我们预计气候变暖的世界将更加湿润。”

根据该方程,气温每升高1°C,空气中的湿度通常会增加约7%,这意味着气候变暖时降雨量可能会更大。

奥利弗·温指出,“对于日以下降雨量,我们看到的比例关系比该方程所显示的还要大。这使得地表水(更有可能)由于短时和高强度的局部降雨增加而在城市形成洪水”。

此外,他表示,“气候变暖正导致大多数地方的海平面上升,这意味着风暴潮造成破坏的基线更高”。

据《中国日报》引述中国气象局国家气候中心首席预报员郑志海称,自四月份以来,中国广东和广西等南部沿海省份频繁出现强降雨,其原因是“高于正常水平的温度”。

郑志海补充说,厄尔尼诺/南方涛动(在2023年中期进入厄尔尼诺升温阶段的自然气候周期)是部分原因,因为其提高了海面温度,并将大量水蒸气从南中国海和孟加拉湾引向中国南部。

宁波诺丁汉大学地理科学系系主任陈加信博士告诉Carbon Brief,今年4月广东的降雨模式与2023年9月6日至8日台风“海葵”过后的强降雨十分相似。

具体而言,强降雨是由来自东南亚和南亚季风模态中的低压湿气流,与来自菲律宾和西太平洋的另一个低压雨带碰撞产生的。

台风“海葵”给香港带来了140年来最严重的暴风雨,并在广东和福建两省造成了最严重的降雨。

陈加信表示,虽然在气象学意义上这些强烈暴风雨并不罕见,但由于全球变暖,其发生的频率越来越高。

四月是季风季的开始。大范围的暴风雨通常在四月平均发生三次。但是,今年中国仅在该月就遭受了至少八次区域性极端降雨事件侵袭,而且都是接连发生的。

在重庆和湖南等受影响地区,河流洪水的现象十分普遍。对于一般的河流洪水来说,确定原因可能更为复杂。

“有很多调节因素。在气候变暖的情况下,较干燥的土壤可能会使土地吸收更多降雨,从而减轻洪水带来的危害。许多洪水不是由强降雨造成,而是由融雪或落在饱和土壤上的低强度、长时间降雨造成的。 因此,单凭气候变暖导致降雨量增加不能合理推断出河流洪水也会增加。”奥利弗·温说。

陈加信表示,自然原因“当然”增加了湿度,“但人类引起的气候变化导致温室效应,造成海水温度上升,从而引起更多的风暴和低压雨带。这是事实。”

奥利弗·温同意,人类导致的气候变化的“热力学影响”增加了与风暴相关的降雨量。

但他补充道:“我们不甚了解的是,人为气候变化如何改变了气候系统的动态,以及这种变化在哪里和如何加剧或抑制了热力学响应。”

人类导致的气候变化起了什么作用?

许多研究发现,海面温度升高正在加剧高强度的连续极端降雨。

联合国政府间气候变化专门委员会(IPCC)的第六次评估报告(AR6)也指出,温室气体排放造成的人为气候变化导致海洋变暖,这也“很可能是已观测到的全球陆地强降水加剧的主要驱动因素”。

根据第六次评估报告,在全球相比工业化前升温1.5°C的情况下,东亚和中亚极端年最大日降雨量(Rx1)和五日累积降雨量(Rx5)预计将比1971年至2000年分别增加28%和15%。

该报告还指出,与之类似的是,在中国的城市群中,“全球从升温1.5°C增加到2°C可能会使非常潮湿日子的总降水强度增加1.8倍,最大五日降水量增加一倍”。

中国气象局中国气象科学研究院的陈阳教授告诉Carbon Brief,中国人为造成的强降雨的强度甚至超过预期。

“由于气候变暖导致大气湿度增加,潜热释放与潮湿风暴中的上升运动之间的反馈作用更强,因此人为造成的中国季风区强降水的加剧程度明显大于预期。”他解释说。

他补充说,与纬度相似的其他地区相比,这种反馈在中国东部尤为明显。

最近发表在《自然》上的一项研究还预计,由于气候变暖,中国的风暴活动将变得更加频繁和剧烈。研究显示,到21世纪末,中国东部沿海热带气旋的年平均发生频率预计将比现在增加16%。

除了人类活动引发的气候变化之外,城市设计和建造不当,以及地下水开采、城市发展导致的建筑物重量、城市交通系统和采矿活动造成的沉降,也会加剧洪灾。

美国路易斯安那州立大学社会学系助理教授凯文·斯迈利(Kevin Smiley)博士告诉Carbon Brief:“气候变化正在加剧极端天气的严重程度和频率。由气候变化引起的额外降雨可能会导致原本只是建筑物的停车场在下雨天出现水坑,而现在洪水会漫过建筑物大门,造成数千美元的损失。”

“重要的是要记住:气候变化是人为的,所以这种风险的增加也有人为的根源。”

中国如何适应日益频繁的洪水?

中国修建了许多大型水利工程来防止洪涝灾害,例如2002年启动的从长江取水的南水北调工程。

在中国国务院最新公布的《国家水网建设规划纲要》中,在2035年前建成“国家水网”是未来防洪的“骨干”措施之一。

文件中的“骨干”工程还包括主要河流上的大型硬工程结构,如堤防、防洪闸和河道泄洪网络,以减轻洪水风险。

与此同时,发表在《海洋与海岸管理》(Ocean & Coastal Management)杂志上的一项研究发现,“基于自然的解决方案”在中国也变得流行起来。

沿海岸线和河口恢复和保护淡水沼泽、红树林和湿地,正在被用来为潮汐和风暴潮提供缓冲。它们包括上海的崇明岛湿地(长江三角洲)和深圳湾的福田和米埔湿地(珠江三角洲)。

规划文件中提出的另一个概念是“加快智慧发展”,利用互联网、数据和技术来监测和预防洪水。

首都北京已整合高清摄像机、望远镜、雷达图和卫星云图的数据,以提供实时灾害更新,从而改善应急响应时间。

中国东部港口城市宁波与电信公司合作,分析大数据并发布信息。

应急管理部表示,这些措施使2018年至2022年因自然灾害造成的死亡和失踪人数与2013年至2017年相比减少了54%。2023年,死亡人数继续下降,但与2018年至2022年水平相比,被毁建筑物数量和直接经济损失分别上升了97%和13%。

2015年,海绵城市的概念被写入住房和城乡建设部的政策文件。该计划在全国推广,武汉(1100万人口)、郑州(1000万人口)等30个主要城市被选为试点城市。

这些海绵城市旨在通过城市地区的“绿蓝设施”,如绿色屋顶、透水路面和雨水公园,收集、净化和再利用至少70%的洪水。整个系统旨在一次性解决城市供暖、淡水匮乏和洪水泛滥等问题。

中国也改进了其恢复过程。例如,在2021年台风“烟花”期间,宁波的洪灾受害者通过改进的在线文件系统,在一小时内就能获得经济补偿。

这些措施效果如何?

陈加信告诉 Carbon Brief,中国“在洪水和干旱灾害的准备、应对和恢复方面做得非常好”,这是两种最具破坏性的自然灾害。

“作为一个全球南方国家,”他将中国称为发展中国家,“中国用海绵城市和增强生态的解决方案应对气候变化,做得相当不错”。

然而,温认为,基于自然的解决方案,如海绵城市,可能会“很快饱和”,因此“它们的作用可能会被夸大”。他继续说:

“这些类型的干预措施对于相对频繁的低强度降雨最有效。在非常强烈、罕见的降雨(其概率在全球变暖的情况下迅速变化)期间,它们将很快不堪重负,造成最大的破坏和痛苦。”

2021 年,一场“历史罕见”的暴雨和洪水影响了海绵城市郑州 1400 多万人,造成 398 人死亡,凸显了海绵城市在气候变化面前的局限性。

《自然》杂志的研究称,海绵城市的设计只能承受 30 年一遇的降雨事件。陈加信说,除此之外,它还会造成一种虚假的安全感。它鼓励更多人迁往高风险地区,导致这些地区的人口和资产增加,而这些聚集地的保护需求也应声而涨,形成一种被称为“堤坝效应”的循环。

堤坝效应是一种悖论:修建防洪堤坝会导致人们对洪水风险的认知降低,业主更有可能投资于自己的房产,从而增加堤坝决口时的潜在损失。

根据《自然》杂志的论文,洪水的影响是人口稠密的黄河三角洲和珠江流域面临的一个关键挑战,这两个地区都面临着很高的洪水风险。

斯迈利说:“当社会的脆弱性与灾害交织在一起时,风险就会显现出来。脆弱性是社会性的,社会脆弱性越大,洪水的影响就越大……社会的脆弱性还是不公平的。一个有一定财富和良好保险的家庭,比一个靠薪水度日的家庭能更快、更成功地从洪水中恢复过来。”

中国政府通过特别政府债券拨款超过一万亿元人民币(1380 亿美元),用于支持弱势公民和今年 3 月遭受自然灾害的地区重建。据官方媒体《环球时报》报道,超过一半的资金将用于“防洪等水利工程建设”。

但过去,财政支持的提供一直受到质疑。全球再保险公司慕尼黑再保险(Munich Re)称,2023 年台风杜苏芮袭击中国时,在总计约 250 亿美元的损失中,只有 20 亿美元得到了承保。

此外,2015 年至 2018 年间,这些海绵城市的建设已经花费了中国 15-18 亿元人民币(2.1-2.5 亿美元)。维护费用将使这笔费用更高。

《自然》杂志的作者建议政府应致力于将分散的“灰色基础设施”(排水沟、管道和泵站等建筑结构)整合到现有的绿色蓝色设施中,但不应仅仅依赖工程基础设施。

中国科学院西北生态环境资源研究所研究员舒乐乐博士告诉《知识分子》杂志:“仅靠传统的工程方法无法减轻目前强降雨的影响”。

“每次下大雨,它造成的损失都会成为头条新闻,主要是因为城市里住着太多人,”舒补充道。

洪水易发地区的政府部门合作不当也导致灾害管理缺乏统一调配。

《自然》杂志的研究补充说,就长江和珠江三角洲而言,其缺乏一个覆盖全区的、且可以“把地划分土和投资融合起来的水文系统”。

中国社会科学院生态文明研究所研究员郑艳博士在 2023 年北京洪水过后指出,政府机构往往只顾自己的管辖范围,只想着转移问题,迅速疏导洪水,这给下游地区的城市带来了压力。

斯迈利说:“洪水不会在意人为划定的市、区或省的边界。一个地方有效的城市设计可能会减轻那里的洪水风险,但会间接增加其他地方的风险。以正义为中心、集体思考(统一筹划)可以提供一个本地化的解决方案来帮助所有人有效恢复,而不是加剧不平等。”

中国可以从其他城市学到什么?

洪水是世界各地城市都面临的挑战,中国因此可以借鉴大量的想法和技术。

《自然》杂志的论文建议,长江三角洲和珠江三角洲可以向恒河-布拉马普特拉河-梅格纳河三角洲和湄公河三角洲学习,“通过利用和调整因气候变化和人类活动而迅速变化的三角洲潜在动态,改善其对沉降和侵蚀等区域挑战的应对”。

该论文还提倡建设一个“积极主动、具有前瞻性、具有足够能力限制洪水破坏性影响并及时恢复灾前状态”的弹性社会。

鹿特丹是一座四面环水、人口 60 万的荷兰三角洲城市。鹿特丹建造了蓄水设施,例如具有蓄水功能、面积相当于四个奥林匹克游泳池的地下停车场, 且安装了绿色屋顶和外墙来吸收雨水。

日本在东京郊区埼玉县在地下建造了一个复杂的混凝土隧道和拱顶网络。这个网络位于大约地下 14 层,可容纳的雨水可以装满 1,000 多个奥运会标准泳池。

这两个城市的地下洪水转移设施经常被用作气候变化前沿城市可行的防洪系统的典范。

香港在跑马地马场的下方也有一个类似的地下雨水储存系统,旨在抵御 50 年一遇的洪水事件。

然而,陈加信表示,防洪措施的有效性难以横向比较,因为每个城市的地理、人口、密度和地形都非常不同。

他告诉 Carbon Brief:“在我看来,中国的特大城市应该考虑利用地下空间来储存超强暴雨突然排放的极端雨水……东京和鹿特丹利用地下空间的做法就相当明智。”

Q&A: What does China’s 15th ‘five-year plan’ for renewables mean for climate change?

Published

on

China has released its “15th five-year plan for the development of renewable energy”, outlining key targets and policies for the sector in 2026-2030.

A key focus of the plan is boosting renewable generation and consumption as a share of China’s overall energy mix.

It calls for continued capacity additions of wind and solar – albeit at lower levels than previous years – as well as hydropower, biomass and other clean-energy sources.

Specifically, China will aim to install 3,500 gigawatts (GW) of renewables capacity by 2030, 2,800GW will be wind and solar.

The country had previously pledged to install 1,200GW of wind and solar by 2030, a goal that China met six years early.

Another major theme is the provision of wind and solar supply that is “dependable” and “grid-friendly”.

Setting a target for “dependable output” from wind and solar could help to entrench their role as a provider of “energy security”, according to analysts.

The government also aims to boost renewables consumption by developing non-power uses of renewable energy, in sectors such as steel and chemicals.

Below, Carbon Brief examines the key targets and policies outlined in the five-year plan and what they mean for China’s energy transition.

Article Contents

Why are China’s five-year plans important?

Five-year plans are key to China’s political system. An overarching plan, covering all socioeconomic issues of importance to policy leaders, is published at the beginning of each five-year cycle.

The plan for the 15th five-year period (2026-2030) was published in March 2026.

It includes what the government considers to be the most important targets and policy signals for climate and energy. For example, binding targets for carbon intensity, the share of non-fossil energy in total energy consumption and total energy production capacity.

Following this overarching document, five-year plans focused on specific sectors or themes are then published over the course of the five-year plan period.

This year, the government has already published several five-year plans related to energy and climate change. One covers the development of the “new-type” energy sector more broadly. Another wraps climate goals together with other environmental targets under the “Beautiful China” programme.

By contrast, the renewables five-year plan focuses specifically on the development of hydropower, wind, solar, biomass, geothermal and wave energy.

It was published in late July by the National Development and Reform Commission (NDRC), the country’s top economic planning agency, and the National Energy Administration (NEA).

It covers topics including capacity and generation targets, as well as efforts to increase integration and reliability of wind and solar. It also has policies to encourage “non-power use” of renewable energy and ways to strengthen innovation of clean-energy technologies.

What overarching renewables targets are in the plan?

China will aim to install 3,500 gigawatts (GW) of renewables capacity by 2030, according to the five-year plan.

Of this, 2,800GW will be wind and solar – a pledge reiterated from China’s action plan for peaking carbon emissions, which was released earlier this month.

The goal more than doubles a previous 2030 target for wind and solar to reach 1,200GW, which China met six years early.

As of June 2026, the country has installed just under 2,000GW of wind and solar capacity, as well as 454GW of hydropower. Biomass, geothermal and wave energy hold very small shares of the overall energy mix.

As such, China would need to build 160GW of wind and solar each year – and just under 220GW of renewable capacity in total – to meet the targets.

The country installed 277GW of new solar alone in 2024 – and 315GW in 2025.

Bar chart titled “China aims for 3,500GW of renewables by 2030”, with the subtitle “China’s total installed capacity of renewable energy from 2016-2025, and its target for 2030, gigawatts”. The chart illustrates the growth of China’s solar, wind and hydro from 2016 to 2025, as well as targets for solar and wind, as well as overall renewables capacity, for 2030. Installed capacity rose from approximately 500GW in 2016 to over 2,200GW in 2025. Solar energy shows the fastest growth, particularly between 2022 and 2025, where it becomes the largest single contributor at over 1,200GW. Wind capacity increases steadily to around 600GW, and hydro capacity reaches over 400GW by 2025. As shown in the right-most bar, or 2030, China targets 3,500GW of total renewables capacity, composed of at least 2,800GW from solar and wind and 700GW from hydropower and other renewables, such as wave energy and biomass.

A key part of meeting the targets will be the development of large-scale clean-energy bases in China’s northern regions. These will generate power to be exported elsewhere via ultra-high voltage lines. The plan also encourages greater “local consumption” and installations of distributed energy (see below).

The plan says that further research will be directed at increasing the renewable share of electricity generated by these large-scale energy bases to 100%.

A recent report by the thinktank Global Energy Monitor (GEM) finds that output from these bases “continues to be paired with coal-fired generation in the name of balancing and system flexibility”. It says that currently, coal generates 42% of the power transmitted to the rest of the country from these bases.

China will also add more hydropower, says the plan, with capacity rising from 448GW in 2025 to 570GW in 2030. Some 160GW of this will be pumped-storage hydropower.

Meanwhile, the plan sets a target for renewable power generation to reach 6,000 terawatt-hours (TWh), 4,000TWh of which would come from wind and solar.

This would be a 50% increase in five years as renewables generated just under 4,000TWh of electricity in 2025, according to the National Energy Administration.

By 2030, the plan says that total consumption of renewable energy will stand at 1.8bn tonnes of coal equivalent (Gtce).

This would be up from 1.2Gtce in 2025, which represented about one-fifth of China’s total energy consumption of 6.2Gtce that year.

The renewable targets in the plan are lower than those suggested in a recent study by high-profile Chinese scholars.

The study, from the department of energy and power engineering and the Institute of Climate Change and Sustainable Development at Tsinghua University in Beijing, assessed the “likelihood of China attaining its carbon peak” under different pathways.

It found that, in order to meet its climate commitments, China would need to either install more than 4,000GW of “non-fossil energy capacity” before 2030, or to “maintain a total energy consumption” below 6.5Gtce.

The table below outlines some of the key renewables targets for 2030, as specified in the plan.

Key targets for 2030, adapted from 15th five-year plan for renewable energy
Type 2025 2030 Percentage change
Renewable energy use 1.2Gtce 1.8Gtce 53%
Total renewables capacity 2,340GW 3,500GW 50%
Wind and solar capacity 1,840GW More than 2,800GW 52%
Of which: Solar thermal 1.8GW 15GW 733%
Hydro capacity 450GW 570GW 27%
Of which: Pumped storage hydropower 66GW 160GW 142%
Wave energy 0.4GW
Renewable generation 4,000TWh 6,000TWh 50%
Of which: Wind and solar 2,300TWh 4,000TWh 74%
Non-electricity use 60Mtce 150Mtce 150%
Renewable hydrogen 0.25Mt 2Mt 700%

Why does the plan focus on ‘firm capacity’ for renewables?

As well as increasing the overall size of China’s renewable power supply, the country must also maintain an “uninterrupted and reliable power supply”, officials from the NDRC and NEA told state news agency Xinhua in coverage of the new plan.

To support this goal, the plan says that the development of renewables will “enter a new stage”. This will mean that “improving quality and serving as a reliable alternative” to fossil fuels will be as important as “expanding scale”.

The plan, therefore, proposes targets for the “firm capacity” from wind and solar (置信出力). This is the amount plants or grids can be relied on to produce during critical supply periods, in conjunction with on-site storage.

The target for wind is a firm capacity of at least 11% of total installed capacity by 2030, while the equivalent goal for solar is 6%.

Wind and solar will also be expected to supply more than 20% of total demand in peak periods during the summer and winter evenings, says the plan. It expects “reliable peak-shaving capacity from renewable sources” to reach more than 300GW.

The new targets are a “positive move”, says Yao Zhe, global policy advisor at Greenpeace East Asia, as it “only applies during peak load and critical supply periods, when coal power is typically used to stabilise the power supply”.

She adds that this could, theoretically, “prevent the construction of new coal-fired power projects that are proposed and approved for the reason of meeting peak demand”.

The new metrics mark a change in focus, says Lyu Wenbin, director general of the Energy Research Institute – a state thinktank under the NDRC – in an “explanatory reading” posted on BJX News. He says it “marks a shift in renewable energy development from the mere pursuit of installed capacity to…also taking into account system support capabilities”.

The plan pledges to “accelerate the construction of grid-friendly wind and solar power stations”. It says this will enhance “reliable peak-load generation” and strengthen renewables’ ability to ensure “safe and stable operation” of the grid.

It says this will particularly be a focus in the energy-hungry east, central and south areas of China.

It sets out a slightly different focus for areas that already have a high share of renewables in their power mix, such as north-west China. Here, the aim will be to develop wind and solar parks that are “capable of providing voltage, frequency and inertia support”.

“This is a real challenge”, says James Norman, research analyst at GEM. He says these challenges are particularly acute in some circumstances:

“[For example], when the share of wind and solar is very high, relatively few synchronous generators (like coal) are online or large volumes of electricity are being transferred through high voltage DC lines.”

The plan mentions many technological solutions to address the problem, he tells Carbon Brief. However, he adds, there are no quantitative details for the issue. For example, he notes there is no target for “how many gigawatts of wind and solar must gain grid-forming capability”. This is in contrast to the goals for overall renewables capacity or generation.

Norman was a co-author on the recent GEM report, which identified further barriers to renewable uptake. It said these include transmission bottlenecks, alongside systemic features such as dispatching and power-contract mechanisms.

As a result, said the report, renewable power – especially solar – is increasingly being “curtailed”, particularly in north-western and northern provinces.

Yao also notes that the plan does not “spell out specific measures to address systemic constraints” around the electricity grid and the role of coal in the power sector.

“I interpret this as evidence that the vested interests are still strong in the policy debate,” she adds.

What does the plan say about ‘distributed’ energy?

Alongside gigawatt-scale clean-energy megabases, China also aims to expand construction of “distributed” energy. This means smaller-scale installations, such as rooftop solar.

More than 300GW of “distributed new energy” is to be added over 2026-30, some 60GW per year.

The plan aims for distributed new energy to be adopted in sectors such as industry, transport, buildings and agriculture.

Applications include the use of distributed solar and wind in industrial parks, coal mines and oilfields, as well as encouraging residents to install solar panels on buildings and developing rural clean-energy grids.

In some regions, distributed solar and wind is “likely to meet a large proportion of local demand”, says Prof Pan Jiahua at the Hong Kong University of Science and Technology (Guangzhou). He tells Carbon Brief that micro- and mini-grids using such resources will be particularly important in central and coastal China.

The 60GW annual target for new distributed energy is not “overly ambitious”, says Isadora Wang, head of China at the thinktank Transition Asia. She tells Carbon Brief that distributed solar additions, alone, exceeded 100GW in both 2024 and 2025.

Cosimo Ries, analyst at the consultancy Trivium China, agrees that the target is reachable. The biggest question mark, he tells Carbon Brief, is whether it will continue to make sense for industry and utilities to build distributed power at the volumes seen during the 14th five-year plan period.

He adds that market conditions for distributed solar have deteriorated sharply over the past two years. He says a range of factors have hit investor confidence:

“[Distributed solar faces] growing exposure to market trading, worsening returns in spot markets, growing risks of curtailment and new policies limiting or forbidding the selling of power back to the grid.”

What does the plan say about non-electricity use of renewables?

The plan also sets goals for renewable energy’s role in “non-electricity use”.

This means using renewable energy for purposes other than generating electricity, through converting it to other forms, such as heat or mechanical energy.

The government is aiming for non-power use to nearly triple from 60m tonnes of coal equivalent (Mtce) in 2025 to 150Mtce in 2030.

Ries tells Carbon Brief that he thinks this target is “one of the main highlights” of the plan. However, he notes that limited available data means it is hard to assess the level of its ambition. He adds that, given the relative conservatism of China’s other recent clean-energy targets, this one may also be met relatively easily.

Key applications for non-power use of renewables include “green hydrogen, ammonia and methanol”, says the plan. It also points to using wind and solar for heat, as well as to biomass and geothermal for heating and cooling.

Green hydrogen, ammonia and methanol are the “centrepiece” of the non-power push, according to state-owned newspaper Economic Information Daily.

For hydrogen alone, China plans to scale up renewable hydrogen production to 2m tonnes in 2030, up from 250,000 tonnes in 2025.

Today, non-power use of renewables accounts for only around 1% of China’s total energy consumption, NEA and NDRC officials said in a Q&A. They added that there is “considerable room for growth” in sectors such as industry, transport and buildings.

Potential new applications include the use of wind and solar for heat. This could see the use of centralised wind and solar heating stations in the chemicals, textiles, pharmaceuticals, papermaking and food sectors.

New projects in the steel and cement sectors should use locally-generated wind and solar to power electric-arc furnaces and kilns, adds the plan.

Wang tells Carbon Brief that she believes the naming of individual sectors is a “clear indication” that they will be included in China’s renewable consumption quotas. These already cover aluminium and other heavy industry sectors.

She adds that power and heat demand from the named sectors may help absorb distributed renewable energy. It will also serve as a testing ground for matching demand with supply through increased grid flexibility and power price reforms.

To Ries, the growing focus on non-power use signals that China’s decarbonisation efforts are “now entering deeper waters”. That means regulators are turning from easier-to-abate sectors, such as aluminium, to more challenging industries, such as steel.

The plan could create a “second growth curve” for the new-energy industry, says He Zhao, in a commentary for China Power News Net. He, the vice-president of the China Electric Power Planning and Engineering Institute (EPPEI). says this might begin with non-power use, before shifting to fuel, feedstock and heat substitution.

What does the plan say about China’s cleantech dominance?

The next five years is a prime opportunity for China to “consolidate our leading position across the entire industrial chain” for clean-energy technologies, says the plan.

It adds that the government will “strengthen technological innovation” and accelerate the roll-out of new applications of artificial intelligence in China’s renewable-energy system.

A particular focus for new R&D will be “cutting-edge, original and disruptive technologies”. It also points to technologies that “enhance the reliability of renewable energy” as a substitute for fossil fuels.

The plan names technologies for further development. For wind power, these include “reliable and low-cost” blades, ultra-tall towers and new types of floating platforms. It also mentions the development of “high-altitude wind power”. For solar, it points to the development of perovskite and other “high efficiency” solar cells, as well as space-solar technologies.

The plan also pledges to develop a power market that supports the “full entry” of renewable-energy companies. It underscores that companies should plan for an increasingly market-based and competitive environment.

Meanwhile, the government will also deepen cooperation with other countries on clean energy and “advance” global climate cooperation, it says.

A priority will be “strengthening” international coordination on investment and development in “green energy projects”. Another is “actively promoting the free circulation of China’s high-quality green technologies and products in global markets”.

Chinese exports of clean-energy technologies have been surging, especially since the closure of the strait of Hormuz.

At the same time, Chinese investment in clean-energy projects in Belt and Road Initiative member states totalled $20bn in the first half of 2026. This is also driven by the crisis.

The US, EU and others have launched tariffs and pricing mechanisms to curb imports of Chinese cleantech. This has contributed to pushback from China, against what it and others refer to as “unilateral trade measures”.

China is transitioning from a “major energy nation” (能源大国) to an “energy powerhouse” (能源强国), writes the Energy Research Institute’s Lyu in his explanatory reading. He says this will enable China to increasingly shift to building “systemic” advantages in developing clean-energy technologies.

He continues that, from 2026-2030, China will “move to the very forefront of the global stage” on clean energy, “venturing into uncharted territory”. This will create both “major new challenges and significant opportunities” for the country, he adds.

International Seabed Authority Assembly underway as calls for deep sea mining moratorium grows

Published

on

SYDNEY/KINGSTON, Wednesday 29 July — The future of deep sea mining will be a focus for world leaders this week as the International Seabed Authority (ISA) Assembly takes place in Kingston, Jamaica.

Country delegates and members from Pacific Civil Society have come together to discuss a deep sea mining code, while the call for a moratorium grows. It follows the ISA’s contentious decision last week to extend The Metals Company subsidiary Nauru Ocean Resources Inc’s (NORI) exploration contract, despite its support for the pursuit of unlawful deep sea mining via US unilateralism.

The Assembly’s agenda was agreed to yesterday, with a science item put forward by Vanuatu to be heard on Thursday local time. Overnight, Mozambique and Mauritius joined the call for a global moratorium.

Rae Bainteiti, Pacific Political Coordinator at Greenpeace Australia Pacific, said from the ISA in Kingston:

“As we move into the General Assembly this week, the fundamental issue remains that there is not enough science to guarantee the safety and protection of the ocean in a world where deep sea mining is allowed. As trustees of the ocean, the common heritage of humankind, our Pacific governments must stand firm against corporate interests that are pushing to move ahead with deep-sea mining outside the ISA framework. If deep sea mining goes ahead, Pacific communities will suffer the economic, cultural and social consequences. We continue to call on all States to support a moratorium as the principled and responsible pathway to protect the ocean.”

Currently, 45 countries, including seven Pacific nations, support a moratorium or precautionary pause on deep sea mining. Last week, Australia’s Labor National Conference committed to supporting a moratorium, but the government has yet to make an official comment.

Analysis: Wind and solar power overtake fossil fuels in Germany for first time ever

Published

on

More of Germany’s electricity came from wind and solar power than fossil fuels for the first time ever in 2025.

Together, wind and solar power generated 225 terawatt hours (TWh) of electricity – accounting for 44% of the total in 2025 – with just 217TWh (43%) coming from fossil fuels.

Solar and onshore wind have grown rapidly under Germany’s “Energiewende” strategy over the past two decades, as the nation transitions away from both coal and nuclear power.

Renewables have recently faced mounting opposition from the far-right Alternative for Germany (AfD) party and the current coalition government has been trying to develop new gas-power plants.

Nevertheless, Carbon Brief analysis of Energy Institute data – shown in the chart below – illustrates how wind and solar have continued growing, emerging as the nation’s largest power source.

The success of renewables in Germany mirrors the EU as a whole, which also saw wind and solar overtake fossil-fuel power generation in 2025 for the first time.

Germany has various targets in place that require a rapid expansion of wind and solar power, including cutting economy-wide emissions to net-zero by 2045.

The nation is also aiming to increase renewables’ share of electricity consumption to 80% by 2030 to achieve a “largely climate neutral” power system by 2035. It aims to decarbonise its electricity entirely once coal power has been phased out, which has a deadline of “no later than” 2038.

(The renewables targets also include electricity generated from hydropower and bioenergy. The latter produces a relatively large share of Germany’s power – roughly a tenth in 2025.)

Germany has to rely on renewables more than neighbours, such as France and the UK, to achieve its climate goals. This is due to its phaseout of nuclear power, which is a key part of the “Energiewende” strategy.

Nuclear power has long faced widespread public opposition in Germany. This year, the centre-right chancellor Friedrich Merz described the nuclear phaseout as a “strategic mistake”, but the government has ruled out a return to conventional nuclear power.

The country has an official coal phaseout date of 2038, but experts say the country is on track to eliminate coal from its power supply years earlier. This is despite some pressure to temporarily slow the transition away from coal during the recent energy crisis.

(Very few outside the AfD are calling to scrap the coal phaseout altogether, but the government will publish a review of the timelines in August.)

While coal generation has fallen quickly, even as nuclear was being phased out, some argue that coal could have been cut more quickly if nuclear had remained.

Gas-power expansion has also been framed by the government in recent years as an essential component of Germany’s transition away from coal and nuclear power, to support a renewables-heavy grid.

The current government under Merz has tried to boost gas and recently adopted a law to provide state support for new gas-fired power plants. The plan is for these plants to be converted to run on “green hydrogen” by 2045, in order to meet the climate-neutrality goal.

Germany aims to install 115 gigawatts (GW) of onshore wind by 2030 and approved a record 20.8GW of new capacity in 2025. 

Meanwhile, solar generation has reached unprecedented levels during the hot summer of 2026.

However, the government’s planned grid reforms have been criticised by the renewables industry for risking slowing down the energy transition. Under the proposals, renewables developers would only be granted automatic grid connections in areas with limited grid capacity if they waive compensation for future curtailed generation.
