Everything we do and use requires a certain amount of energy to do the work. That work is now performed mostly by technology thus increasingly removing people’s ability to garner incomes.
Instead of loading a depository (financial intuition) with diminishing access to a monetary fund of some kind, we determine what physical resources are available to convert to an energy source; divide that available energy into the population and give each their share of what we now could call “energy credits.”
The result is the ability to consume and use services far beyond what we consider adequate today. The only difference we would notice from today, is the depository has enough credits that we no longer have to worry about an “overdraft.”
