Wind and solar grew rapidly, but fossil power also expanded风电和太阳能快速增长，但化石能源发电也在扩张

01The Story新闻事实

Wind, solar and other non-hydro renewables supplied 19.8% of global electricity in 2025, up from 2.0% in 2005, and are projected to reach 21.8% in 2026. Fossil generation also grew as global electricity demand rose 75% between 2005 and 2025, highlighting the importance of comparing today’s system with a counterfactual without clean-energy growth.风电、太阳能和其他非水电可再生能源在2025年占全球发电量的19.8%，高于2005年的2.0%；预计2026年将达到21.8%。与此同时，全球电力需求在2005年至2025年间增长75%，化石能源发电也继续增加，因此评估清洁能源影响时需要与“没有清洁能源增长”的反事实情景比较。

• Non-hydro renewables supplied 2.0% of global electricity in 2005, 6.8% in 2015 and 19.8% in 2025.非水电可再生能源占全球发电量的比例从2005年的2.0%升至2015年的6.8%，并在2025年达到19.8%。
• The IEA projects non-hydro renewables to provide around 21.8% of global electricity in 2026, slightly above natural gas at 21.6%.国际能源署预计，非水电可再生能源在2026年将提供约21.8%的全球电力，略高于天然气的21.6%。
• Global electricity demand increased by 75%, or 13,600 TWh, between 2005 and 2025.2005年至2025年间，全球电力需求增长75%，增量为13,600太瓦时。
• Between 2005 and 2025, wind and solar supplied 5,400 TWh of new electricity demand, while fossil fuels supplied 6,100 TWh.2005年至2025年间，风电和太阳能满足了新增电力需求中的5,400太瓦时，化石能源满足了6,100太瓦时。
• Global fossil electricity generation was around 50% higher than in 2005; coal generation rose by 3,300 TWh and gas generation by 3,200 TWh.全球化石能源发电量比2005年高出约50%；煤电增加了3,300太瓦时，燃气发电增加了3,200太瓦时。

The rapid growth of renewables has supplied a substantial share of rising electricity demand, but has not yet prevented fossil-fuel generation from reaching higher levels.可再生能源的快速增长满足了不断上升的电力需求中的相当一部分，但尚未阻止化石能源发电量继续创出更高水平。

Key takeaway核心结论

Renewables have grown rapidly and met a major share of new electricity demand, but total fossil generation has continued to rise because global demand expanded substantially.可再生能源快速增长并满足了新增电力需求中的重要部分，但由于全球需求大幅扩张，化石能源发电总量仍在上升。

04What to Watch后续关注

1. Whether non-hydro renewables exceed natural gas in global electricity generation in 2026.2026年非水电可再生能源是否会超过天然气，成为全球第二大电力来源。
2. Whether continued electricity-demand growth in emerging and developing economies is met increasingly by clean energy rather than fossil fuels.新兴经济体和发展中经济体持续增长的电力需求，未来是否更多由清洁能源而非化石能源满足。
3. Whether coal and gas generation continue reaching new highs despite rising renewable generation.在可再生能源发电量上升的同时，煤电和燃气发电是否会继续创下新高。
