[edit] Energy management
Energy accounting is a system used in energy management systems where measuring and analyzing energy consumption is done to improve energy efficiency within an organization.[3]
Various energy transformations are possible. An energy balance can be used to track energy through a system. This becomes a useful tool for determining resource use and environmental impacts. How much energy is needed at each point in a system and in what form that energy is, can be measured. An accounting system keeps track of energy in, energy out, and non-useful energy versus work done, and transformations within a system. Sometimes, non-useful work is what is often responsible for environmental problems.[4]
[edit] Energy balance
Energy return on investment (EROEI) is the ratio of energy delivered by an energy technology to the energy invested to set the technology up.
