The idea of a consumable currancy is really risky. The price of goods will be correlated to the total supply of money, leaving prices unstable as the currency is created and destroyed st different rates. You'd end up with another fractional system to keep it more stable, where the currency isn't actually pegged to a certain amount of power. You could end up with a run on the banks situation, where there are people trying to spend their money to cool their houses in the summer only to find out that more claims on energy (the money) exist than actual power available.
