Energy geographers have characterized energy as a borderland topic because of its ability to straddle and interconnect different geographic concepts and debates. In this review, we evaluate how the borderland of energy geographies has been emerging in recent years by analyzing scholarship on energy published in top geography journals and a leading energy studies journal, Energy Research & Social Science. In part 1 of our review, we evaluate how the borderland of energy geographies is evolving by mapping the geographic range of empirical studies, the processes and types of energy systems being researched and the key geographic concepts/theories engaged across the four main sub‐fields of geography. We find that energy geographies scholarship has primarily centered on the Global North, remains focused on the extractive and production phase of energy development and is evolving across and within three of the four sub‐fields of geography. Energy transitions, governance, justice, space, and landscape are key topics and concepts examined. Notable underrepresentations include a relative lack of energy geographies scholarship within physical geography, as well as limited studies that engage geographic concepts to study the transportation sector, unconventional energy development and the food‐energy‐water nexus. In part 2, we identify three broad research themes to expand the frontier of energy geographies: (a) geographies of energy knowledge production, particularly indigenous knowledge; (b) materializing energy, especially through engaging political‐industrial ecology; and (c) advancing geographic thought by critically assessing how studying energy advances/challenges/transforms core geographic concepts and debates. Collectively, our review demonstrates that energy geographies have established firm footing within and across geography. Deepening engagement with emerging trends elsewhere in geography and the social sciences will not only help to better conceptualize what a geographic perspective on energy means but will also help to make clearer sense of the rapid economic, social, environmental, and political transformations currently underway within the global energy system.

不断演变的能源地理边界

能源地理学家将能源作为边境地区的主题来描述，是因为它具有跨越和联系不同地理概念和辩论的能力。在这篇评论中，我们通过分析在顶级地理杂志和领先的能源研究期刊《能源研究与社会科学》上发表的能源奖学金来评估近年来能源地理的边界领域如何发展。在我们的审查的第1部分中，我们通过绘制实证研究的地理范围，正在研究的能源系统的过程和类型以及跨四个主要子领域的关键地理概念/理论，评估了能源地理的疆土如何演变地理。我们发现，能源地理学的奖学金主要集中在全球北部，仍然侧重于能源开发的开采和生产阶段，并且在地理学的四个子领域中的三个领域内和内部不断发展。能源转型，治理，正义，空间和景观是研究的关键主题和概念。代表性不足的案例包括自然地理领域内相对缺乏能源地理学的奖学金，以及涉及地理学概念来研究运输领域的有限研究，非常规能源发展与食品-能源-水关系。在第2部分中，我们确定了三个广泛的研究主题来扩展能源地理学的前沿领域：（a）能源知识生产的地理学，尤其是本地知识；（b）物化能源，特别是通过参与政治工业生态；（c）通过批判性地评估研究能源如何进步/挑战/转变核心地理概念和辩论来推进地理思想。总体而言，我们的审查表明，能源地理已经在地理内部和整个地理范围内建立了牢固的立足点。加深对地理学和社会科学其他领域新兴趋势的参与，不仅将有助于更好地概念化地域能源观点意味着什么，还将有助于使人们对快速的经济，社会，
