At which point the concept of money becomes trivial at best, it wont go away, there will always be value for scarce things of use.... but the need for it will certainly decrease as time goes on.
That discussion is a bit beyond this particular thread, but market forces WILL ALWAYS dictate the value of scarce things (nearly everything). The only way your scenario can happen is if each human being can create this energy (mindpower x chi' + crystals^2, or something) for nothing, because there will always be original capital costs.
Truly infinite energy? Wow. No idea what happens then. All bets are off. I still think my comment above won't change. 8^]
Do not forget the knowledge, entertainment, art, qualification, friendship etc. Even with abundant energy (and Startrek-like replicator) those will be scare and wanted.
