The purpose of this research is to explore the structure of employee energy and analyze its differences in demographic variables as well as the differences between groups. The study collected 294 questionnaires of employees in Chinese insurance companies. Confirmatory factor analysis and one‐way analysis of variance (ANOVA) were used in the data analysis. The results showed that employee energy is a three‐dimensional concept that comprises basal energy, growing energy, and behavioral energy. Employee energy only has significant differences on monthly income and the level of positions, and the employees who have high employee energy share the characteristic of both high monthly income and the level of positions. Respondents were divided into four groups: 1) high‐positive‐energy, 2) low‐positive‐energy, 3) low‐negative‐energy, and 4) high‐negative‐energy employees. High‐positive‐energy employees showed the characteristics of high basal energy, high growing energy, and high behavioral energy, showing a feature of plump wings. Finally, this research put forward suggestions to provide a reference for energy management. © 2016 Wiley Periodicals, Inc.
