🤖 AI Summary
**要約(日本語)**
2025年、中国は太陽光・風力の導入が急増する一方で、過去数年に比べてはるかに多くの石炭火力発電所を建設したことが報告された。主なポイントは以下の通りです。
- **新設石炭ユニット**:1 GW以上の大型ユニットが50以上稼働開始し、総計で78 GWの新たな石炭発電容量が追加された。これは過去10年でインドが10年間に建設した容量を上回る規模。
- **再生可能エネルギーの伸び**:同年、太陽光は315 GW、風力は119 GWの新設で、再エネ総量は大幅に増加。結果として石炭発電のシェアは約1 %低下した。
- **政府の姿勢**:石炭は風力・太陽光のような変動電源の安定的なバックアップと位置付けられ、2022年の水不足による水力不足を受けた供給不安を補う目的でもある。
- **懸念点**:大量の石炭容量拡大は、老朽化・非効率な石炭プラントの早期廃止を阻害し、クリーンエネルギーへの転換を遅らせるリスクが指摘されている。
- **報告書の提言**:次の五か年計画(2025‑2030年)で、電力部門の排出増加を防止し、老朽石炭プラントの早期退役を加速することを求めている。
**結論**
中国は再生可能エネルギーの急成長と同時に、電力供給の安定確保を理由に大規模な石炭火力投資を続けているが、これが温室効果ガス削減目標やクリーンエネルギーへの移行に逆行する恐れがある。政策面での明確な排出抑制策と石炭プラントの退役が求められている。

Even as China's expansion of solar and wind power raced ahead in 2025, the Asian giant opened many more coal power plants than it had in recent years — raising concern about whether the world's largest emitter will reduce carbon emissions enough to limit climate change.
More than 50 large coal units — individual boiler and turbine sets with generating capacity of 1 gigawatt or more — were commissioned in 2025, up from fewer than 20 a year over the previous decade, a research report released Tuesday said. Depending on energy use, 1 gigawatt can power from several hundred thousand to more than 2 million homes. Overall, China brought 78 gigawatts of new coal power capacity online, a sharp uptick from previous years, according to the joint report by the Centre for Research on Energy and Clean Air, which studies air pollution and its impacts, and Global Energy Monitor, which develops databases tracking energy trends. "The scale of the buildout is staggering," said report co-author Christine Shearer of Global Energy Monitor. "In 2025 alone, China commissioned more coal power capacity than India did over the entire past decade."
At the same time, even larger additions of wind and solar capacity nudged down the share of coal in total power generation last year. Power from coal fell about 1% as growth in cleaner energy sources covered all the increase in electricity demand last year. China added 315 gigawatts of solar capacity and 119 gigawatts of wind in 2025, according to statistics from the government's National Energy Administration...
The government position is that coal provides a stable backup to sources such as wind and solar, which are affected by weather and the time of day. The shortages in 2022 resulted partly from a drought that hit hydropower, a major energy source in western China... The risk of building so much coal-fired capacity is it could delay the transition to cleaner energy sources [said Qi Qin, an analyst at the Centre for Research on Energy and Clean Air and another co-author of the report]... Political and financial pressure may keep plants operating, leaving less room for other sources of power, she said. The report urged China to accelerate retirement of aging and inefficient coal plants and commit in its next five-year plan, which will be approved in March, to ensuring that power-sector emissions do not increase between 2025 and 2030.
