A method and process provides an approach to optimizing energy costs or any similar fungible, consumable commodity in real time use by defining and utilizing a novel analytic metric based on the ratio of the actual cumulative cost of the commodity used compared to the absolute minimum cost of the commodity during the time period under consideration. The historical energy management approach uses the price of the commodity and then tries to lower the total cost of energy use during the most expensive time periods. It may not be possible with the existing energy management techniques to be able to meet all the operational requirements of the user and still have the minimum cost of use. As a result of this invention, the user can be guaranteed the optimal energy use at the absolute minimum cost, and if the minimum is not achievable the invention allows the user to quantify how efficient his operation is, compared to the theoretical optimum. The use of a new metric called the Energy Performance Index (EPI) allows this comparison to be made across all energy use platforms. Substantial increases in efficiency, performance and economics can be achieved with this invention.
