if i were the supreme dictator of the world, i would replace currency as a form of exchange, and use Joules as a form of exchange, and then mandate that all energy production be distributed equally to every single living human. E.g., lets assume 30 petawatthours of energy per year(approx 108 000 peta joules), divided by 6 billion people, is approx 18000000000 joules per year, or approx 50 million joules per day for each person.
To pay for food, you "pay" the amount of joules it takes to fuel the robots that create your food. Ditto with any automatable production (clothing, houseing), and any land has a tax equivalent of the amount of solar energy extractable from the land.
You could attempt to save your joule allocation, but i suspect it will become too difficult. You cannot borrow joules the way you can borrow money (that is, the "bank" cannot be a fractional reserve system). But you would be encouraged to invest your joule allocation into useful endeavours, such as scientific research, which is always made available to all to use.
You can get richer by investing in improvements, and get richer by growing the size of the pie. There would be no way to get richer at the expense of making someone else's allocation lower.
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?)
