Abstract:  The study of energy at work has developed from individual level towards interactive and collective levels. Based on a contingency perspective, this paper starts with interpreting the connotation of different energy patterns and discriminating them from other similar conceptions, and then constructs the convective transformation model of energy expression patterns with the basic of interaction ritual theory, to provide new ideas for maintaining and replenishing energy at work. Future studies should pay more attention to the dual-effects of relational energy and collective energy within organizations, and indigenous empirical studies should be carried out as well.

Key words:  energy, multilevel, expression patterns, convective transformation
