Money is an abstraction. A useful abstraction of low complexity that people can coordinate on. Calling it a resource like energy makes sense to me on that abstraction level. But there are Weird Things About Money. People are optimizing relative wealth, not absolute wealth, and happiness is proportionate to wealth relative to peers (Envy Dominates Greed). Thus coordinating on this specific resource is sub-optimal globally even if it is efficient for individual participants locally.
The same should hold for energy as long as you can convert money to energy.
