Energy balance information


Energy balance may refer to:

  • Earth's energy balance, the relationship between incoming solar radiation, outgoing radiation of all types, and global temperature change.
  • Energy accounting, a system used within industry, where measuring and analyzing the energy consumption of different activities is done to improve energy efficiency
  • Energy balance (biology), a measurement of the biological homeostasis of energy in living systems
  • Energy balance (energy economics), verification and analysis of emergence, transformation and use of energy sources within an economic zone
  • Energy economics, where the energy balance of a country is an aggregate presentation of all human activities related to energy, except for natural and biological processes
  • Energy Economics (journal), a scientific journal published by Elsevier under its "North Holland" imprint
  • Energy returned on energy invested (EROEI), ratio of the amount of usable energy acquired from a particular energy resource to the amount of energy expended to obtain that energy resource
  • First law of thermodynamics, according to which energy cannot be created or destroyed, only modified in form
  • Groundwater energy balance, comparing a groundwater body in terms of incoming hydraulic energy associated with groundwater inflow and outflow
