The harvesting of energy credits due to the transformation of a real estate property. The transformation results in improved energy usage of the real estate property, resulting in energy credits being earned by the owner of the real estate property. The energy credits are obtained by monitoring the power usage of the real estate property before the transformation, and after the transformation. An entity other than the owner of the real estate property facilitates the transformation by providing products or instructions that help make the transformation, or perhaps even by the entity taking at least partially responsibility for making the transformation. In consideration for the facilitation of the transformation, the entity receives at least a portion of the energy credits that result from the transformation.
