The paper examines three social dimensions of energy. The first one is cognitive; energy is a way of knowing, a macro-concept which works as a frame. Moreover, energy is conceived as a social product; its physical aspects are inextricably bound up with human interactions and meaning attributions. The second dimension is energy organisation. Energy is an instrument used by human beings in order to
achieve a goal. In that sense, energy can be assimilated to a technology: that is, a set of knowledges, tools, and actions assembled according to certain rules and traditions. Of energy as organisation it is interesting to consider how it becomes an institution. Its third dimension is practical: it guides our behaviour. This meaning sums up the other two. Energy consumption makes it possible to understand
different lifestyles, different logics of action, different habits or customs. It is intrinsic to the most common practices. Worries about consumption or resources depletion are included in some practices of which energy is one of the most
important components. The paper concludes with a comment on the energy crisis as a test for the illustrated multidimensional scheme.
