This article introduces the concept of ‘exergy’, which is a thermodynamic quantity, to show what resource is, and what consumption is. Exergy is the ability of energy and matter to disperse into their environmental space. The first part of this article briefly describes the essence of the exergy concept, and the second part describes a simple example of exergy calculation with respect to electric lighting and thereby reviews the importance of daylighting as one of the environment‐conscious technologies.
