Energy as currency is interesting, but still has problems where cheap energy such as oil and coal has side effects which do affect others. And are you constantly "rebaselining" the division of energy production or to you let the accumulation ride? If you let it ride, you'll have the same slow redistribution of a wealth gap between those who are capable/lucky enough to get a little bit of a headstart and continue to leverage it to more and more wealth. (or do you think you need some hybrid between the two, some something else entirely?)
