Energy accounting
Template:Short description Energy accounting is a system used to measure, analyze and report the energy consumption of different activities on a regular basis.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> This is done to improve energy efficiency,<ref name=Acc>Accounting: Facility Energy Use (in Encyclopedia of Energy Engineering and Technology)</ref> and to monitor the environment impact of energy consumption.
Energy management
Energy accounting is a system used in energy management systems to measure and analyze energy consumption to improve energy efficiency within an organization.<ref name=Acc /> Organisations such as Intel corporation use these systems to track energy usage.<ref>E. Curry, B. Guyon, C. Sheridan, and B. Donnellan, “Developing an Sustainable IT Capability: Lessons From Intel’s Journey,” MIS Quarterly Executive, vol. 11, no. 2, pp. 61–74, 2012.</ref>
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 is measured, as well as the form of that energy. 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.<ref>Science Notes: Energy Accounting and Balance Template:Webarchive</ref>
Energy balance
Energy returned on energy invested (EROEI) is the ratio of energy delivered by an energy technology to the energy invested to set up the technology.
