•We conducted bibliometric analysis on emergy from 1996 to 2014.•Citespace software was used to visualize the literature data.•The trend and publication patterns of existing emergy literature were reported.•The intellectual core of emergy research was identified through citation analysis.
A bibliometric approach, along with Citespace software, was used to quantitatively and visually evaluate global scientific research on emergy from 1996 to 2014. 637 publications – in accordance with the search criteria from the Science Citation Index Expanded (SCI-Expanded) and Social Science Citation Index (SSCI) of the Web of Science database – were statistically analyzed. The assessments on document type and language, publication year, authorship, subject categories and journals, countries/territories and institutions, most-frequently cited publications and author keywords were conducted with respect to seven categories. The amount of emergy publications per year has sharply increased in recent years. The most productive author was S. Ulgiati with 50 articles, who was also one of the most frequently cited publication authors. China produced 35.95% of all pertinent publications followed by the USA with 25.59% and Italy with 21.66%. Ecological Modeling, Ecological Engineering and Ecological Indicators were the three most common journals in this field. By synthetically analyzing the keywords, the dominant hot spots of emergy research could be concluded as “energy”, “sustainability”, “transformity”, and “indicators”.
