可再生和可持续能源的科学技术对我们未来的社会和经济是不可或缺的。为了实现可持续能源发展的目标，全球范围内的研究努力越来越多。能源研究的规划者必须掌握科学和技术研究的更广泛的覆盖面，并对有前途的和新兴技术的有效投资做出决策，特别是在资源有限的情况下。本文利用引文网络分析方法，对能源研究中的新兴研究领域进行了追踪。我们的分析证实，燃料电池和太阳能电池是能源研究中快速增长的领域。通过对这两个领域中的出版物进行聚类，我们进一步研究了这两个领域的详细结构。每个引文集群都有自己的特色研究课题，并且集群之间呈现出不同的增长趋势。通过引文网络分析，我们可以高效地在一堆出版物中跟踪新兴的研究领域。(C)2007 Elsevier Inc.保留所有权利。
Science and technology for renewable and sustainable energy are indispensable for our future society and economics. To meet the goal of sustainable energy development, there is a growing body of research efforts world wide. The planner of energy research has to grasp the broader coverage of scientific and technological research, and make decisions on effective investment in promising and emerging technologies especially under circumstances of limited resources. In this paper, we track emerging research domains in energy research by using citation network analysis. Our analysis confirms that the fuel cell and solar cell are rapidly growing domains in energy research. We further investigate the detailed structure of these two domains by clustering publications in these domains. Each citation cluster has characteristic research topics, and there is a variety of growth trends among the clusters. By using citation network analysis, we can track emerging research domains among a pile of publications efficiently and effectively. (C) 2007 Elsevier Inc. All rights reserved.
