Can solar energy reach everyone, everywhere by 2030?太阳能能否在2030年前惠及“所有人、所有地方”？

An open letter signed by climate leaders urges governments, businesses and the public to provide clean, affordable energy to everyone, everywhere by 2030. Solar capacity and renewable generation are expanding rapidly, but universal access would require faster electrification, major financing and stronger political backing, especially in regions where electricity access remains limited.一封由气候领域领导者签署的公开信呼吁各国政府、企业和公众在2030年前让所有人、所有地方都获得清洁且可负担的能源。太阳能装机容量和可再生能源发电正在快速增长，但要实现普遍供电，仍需加快电气化、扩大融资并获得更强的政治支持，尤其是在电力供应仍有限的地区。

01The Story新闻事实

An open letter signed by climate leaders urges governments, businesses and the public to provide clean, affordable energy to everyone, everywhere by 2030. Solar capacity and renewable generation are expanding rapidly, but universal access would require faster electrification, major financing and stronger political backing, especially in regions where electricity access remains limited.一封由气候领域领导者签署的公开信呼吁各国政府、企业和公众在2030年前让所有人、所有地方都获得清洁且可负担的能源。太阳能装机容量和可再生能源发电正在快速增长，但要实现普遍供电，仍需加快电气化、扩大融资并获得更强的政治支持，尤其是在电力供应仍有限的地区。

  • Global solar power increased by a record 30% in 2025 compared with the previous year and has risen more than tenfold since 2015.全球太阳能发电量在2025年较前一年创纪录增长30%，较2015年增加了十倍以上。
  • Installed solar capacity worldwide stands at about 3 terawatts, while roughly 1 terawatt of new photovoltaic capacity is produced each year.全球太阳能累计装机容量约为3太瓦，而全球每年新增光伏产能约为1太瓦。
  • About 655 million people still lack access to electricity, and the electrification pace in Sub-Saharan Africa would need to triple to achieve universal access by 2030.目前约有6.55亿人仍无法获得电力；若要在2030年前实现普遍供电，撒哈拉以南非洲的电气化速度需要提高至三倍。
  • Renewable energy sources overtook coal in the global electricity mix in 2025 for the first time in 100 years, according to Ember.Ember称，2025年可再生能源首次在全球电力结构中超过煤电，这是100年来的首次。
  • Meeting global energy demand entirely with renewables could require about 50 terawatts of capacity, according to Eicke Weber.Eicke Weber表示，如果全球能源需求完全由可再生能源满足，可能需要约50太瓦的装机容量。

Solar deployment is advancing faster than expected, but reaching universal clean-energy access by 2030 depends on financing, infrastructure and political will as much as on technology.太阳能部署速度超出预期，但要在2030年前实现清洁能源普及，融资、基础设施和政治意愿与技术本身同样关键。

Comparison对比

Rapid growth, large remaining gap快速增长与巨大的剩余缺口

Solar growth has accelerated sharply, yet current installed capacity remains far below the level some experts associate with a fully renewable global energy system.太阳能增长明显提速，但当前累计装机容量仍远低于部分专家认为实现全球可再生能源体系所需的水平。

Installed solar capacity太阳能累计装机容量

Current目前3 TW

Estimate估计50 TW

  • Solar capacity has grown more than tenfold since 2015.太阳能装机容量较2015年增长了十倍以上。
  • The world currently produces about 1 terawatt of new photovoltaic capacity each year.目前全球每年生产约1太瓦的新增光伏产能。
Stakeholder impact利益相关方

Electricity access remains the central test电力可及性仍是核心考验

The 2030 goal is not only about adding generation capacity. It also requires connecting people who lack electricity, with Sub-Saharan Africa identified as requiring a much faster pace of electrification.2030年目标不仅是增加发电装机容量，还要让缺乏电力的人接入电力系统；撒哈拉以南非洲被指出需要大幅加快电气化速度。

  • The article says areas without electricity could move directly to clean technologies rather than first building fossil-fuel systems.文章称，没有电力的地区可以直接采用清洁技术，而不是先建设化石燃料系统。
Cause因果关系

Technology exists; deployment depends on policy and finance技术已经具备，部署取决于政策与融资

Experts cited in the article say solar and battery technologies are available and costs have fallen, but a global transition would require a major political program and blended finance from public and private institutions.文章援引的专家表示，太阳能和电池技术已经具备，成本也已下降，但全球能源转型仍需要大规模政治行动，以及公共和私营机构提供混合融资。

  • Eicke Weber said battery costs have fallen alongside the cost of solar modules.Eicke Weber表示，电池成本已与太阳能组件成本一同下降。
  • Catherine McKenna called for funding from governments, the World Bank, the African Development Bank and the private sector.Catherine McKenna呼吁各国政府、世界银行、非洲开发银行和私营部门提供资金。
Future signal前瞻信号

2030 ambition versus longer global timelines2030年目标与更长期的全球时间表

The experts describe universal clean energy by 2030 as possible but highly ambitious. One estimate in the article suggests that reaching 80% to 90% renewable electricity worldwide could take until 2040.专家认为，2030年前实现清洁能源普及并非不可能，但目标极为激进。文章中的一项估计称，全球可再生能源发电占比达到80%至90%可能要到2040年。

  • Estimate估计 2,040 year2,040年
  • The open letter calls for clean, affordable energy for everyone, everywhere by 2030.公开信呼吁在2030年前让所有人、所有地方获得清洁且可负担的能源。
