Abstract

Africa’s role in the global energy transition is undeniable as the least electrified yet fastest-growing continent on the globe, crucially in need of economic development and investment in climate resilience. Africa is on track to become the most populous continent by 2050, housing almost 80% of the world’s poor, almost 90% of those without energy access, and the most climate-vulnerable communities—all while having contributed less than 5% of global carbon emissions. Delivering climate-proofed prosperity to this growing population will require paying major attention to the continent’s energy systems, which remain underdeveloped and severely under-resourced. Africa’s power systems are largely underdeveloped, in part given the historical context in which its power utilities emerged. This presents African countries with a set of circumstances and challenges in achieving universal energy access and energy sector growth which are much different from those faced by their advanced energy market counterparts. At roughly 230 GW of installed generation, the entire continent’s generation capacity is roughly half that of India alone [1]. To truly deliver sustainable economies, dignified jobs, and prosperity for all, power supply must grow significantly—and is expected to quadruple by 2040 [2]. However, this energy system expansion is complex, especially given the immense difficulty of securing investment from the international finance community to further expand renewables on the continent; the very real and practical challenges of delivering mass amounts of reliable power entirely through intermittent renewable resources; the challenge of bringing full sectors such as transportation onto grid, far less weak grids; and the continent’s growing industrialization agenda which involves many non-electricity energy feedstock needs. With the international energy agency (IEA)’s conclusion that no new oil or gas reserves could be explored or developed to stay under the global 1.5 C threshold, Africa’s energy transitions and the role of abundant domestic fuels such as natural gas have now become a timely and polarizing debate. As such, dialogues around Africa’s future energy systems are intensifying. There is a risk that some positions are hardening, and that the space for fact-based discussion on key topics, including as the role of fossil fuels, is narrowing. In a vacuum of comprehensive and digestible data, and spaces that prioritize local voice, there is a grave risk of predetermining Africa’s options, rather than co-developing ambitious, credible new pathways based on perspective sharing and the pledge of support. This is an urgent risk to mitigate against. Energy transition decisions and policy determined now will carry tremendous weight, with nearand long-term implications for Africa’s economic trajectories, carbon lock-in, international partnerships, trust, and multilateralism, and moreover, the prosperity of millions. This Focus Issue aims to inject into the dialogues and debates a substantive body of work from predominantly local scholars across the continent that helps unpack the practical challenges of delivering Just Transitions. This Focus Issue explores the ways in which energy service delivery influences and can be influenced by other system transformations on the continent. The Issue aims to identify novel tools, methods and insights that can contribute to faster, efficient, and cost-effective delivery of energy plans, as well as the challenges and opportunities therein, and to grow the research base for energy transition dialogue in Africa.
撒哈拉以南非洲能源转型的实际解决方案
作为全球电气化程度最低但增长最快的大陆,非洲在全球能源转型中的作用是不可否认的,它迫切需要经济发展和气候适应投资。到2050年,非洲将成为人口最多的大陆,居住着世界上近80%的穷人,近90%无法获得能源的人,以及最易受气候变化影响的社区,而所有这些都只占全球碳排放量的不到5%。为不断增长的人口提供不受气候影响的繁荣,需要重点关注非洲大陆的能源系统,该系统仍然不发达,资源严重不足。非洲的电力系统在很大程度上是不发达的,部分原因是其电力设施出现的历史背景。这使非洲国家在实现普遍获得能源和能源部门增长方面面临一系列情况和挑战,这些情况和挑战与发达能源市场国家所面临的情况大不相同。整个非洲大陆的发电装机容量约为230吉瓦,约为印度的一半[1]。为了真正实现可持续的经济、体面的就业和所有人的繁荣,电力供应必须大幅增长——预计到2040年将翻两番[2]。然而,这种能源系统的扩张是复杂的,特别是考虑到从国际金融界获得投资以进一步扩大非洲大陆的可再生能源的巨大困难;完全通过间歇性可再生资源提供大量可靠电力的非常现实和实际的挑战;将交通运输等整个行业纳入电网的挑战,更不用说薄弱的电网了;非洲大陆日益增长的工业化议程涉及许多非电力能源原料需求。国际能源机构(IEA)的结论是,如果要将全球升温幅度控制在1.5摄氏度以下,就不可能勘探或开发新的石油或天然气储量。因此,非洲的能源转型以及天然气等丰富的国内燃料的作用,现在已经成为一场及时而又两极分化的辩论。因此,围绕非洲未来能源体系的对话正在加强。有一种风险是,一些立场正在变得强硬,对关键议题(包括化石燃料的作用)进行基于事实的讨论的空间正在缩小。在缺乏全面、易于理解的数据和优先考虑当地声音的空间的情况下,存在预先决定非洲选择的严重风险,而不是在分享观点和承诺支持的基础上共同制定雄心勃勃、可信的新途径。这是一个迫切需要缓解的风险。现在确定的能源转型决策和政策将具有巨大的影响力,对非洲的经济轨迹、碳锁定、国际伙伴关系、信任和多边主义,甚至对数百万人的繁荣都具有近期和长期的影响。本期焦点议题旨在为对话和辩论注入大量来自非洲大陆主要是当地学者的工作,这些工作有助于揭示实现公正转型的实际挑战。本期焦点问题探讨了能源服务提供对非洲大陆其他系统转型的影响和可能受到影响的方式。该问题旨在确定有助于更快、高效和具有成本效益地实施能源计划的新工具、方法和见解,以及其中的挑战和机遇,并扩大非洲能源转型对话的研究基础。
