Energy accounting is a system used within industry, where measuring and analyzing the energy consumption of different activities is done to improve energy efficiency.^[1]

Heat, a form of energy, is the amount of random molecular kinetic energy.

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.^[2]

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.^[3]

Energy return on investment (EROEI) is the ratio of energy delivered to energy costs.

Flows of energy and CO₂ in an ecosystem.

Energy quality is the contrast between different forms of energy, the different trophic levels in ecological systems and the propensity of energy to convert from one form to another.

Rapidly advancing technologies mean it is now technically possible to achieve a transition of economies, energy generation, water and waste management, and food production towards sustainable practices using methods of systems ecology and industrial ecology.^[4][5]
