The way I understand "energy" (this may be totally different from Gulenko's view) is that it comprises all of the non-reusable resources available to the psyche (possibly also including physical energy and effort). Information itself is a kind of resource but it is a reusable/copyable one: if you send someone a piece of information you can keep your copy of it. This is not true about money, for example, or time and space. At the meta-level generally deals with reusable resources while deals with non-reusable resources. So in a sense this completes the picture initially painted by Augusta.
