  2. Earth's energy budget - Wikipedia

    en.wikipedia.org/wiki/Earth's_energy_budget

    Earth's energy budget (or Earth's energy balance) is the balance between the energy that Earth receives from the Sun and the energy the Earth loses back into outer space. Smaller energy sources, such as Earth's internal heat, are taken into consideration, but make a tiny contribution compared to solar energy.

  3. Energy balance - Wikipedia

    en.wikipedia.org/wiki/Energy_balance

    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

  4. Energy balance (energy economics) - Wikipedia

    en.wikipedia.org/wiki/Energy_balance_(energy...

    Energy balance, in terms of energy economics, is concerned with all processes within an organization that have a reference to energy. It derives from the ecobalance and has the ambition to analyze and verify the emergence, transformation and use of energy resources in an organization in detail. [ 1 ]

  5. First law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/First_law_of_thermodynamics

    The law also defines the internal energy of a system, an extensive property for taking account of the balance of heat and work in the system. Energy cannot be created or destroyed, but it can be transformed from one form to another. In an isolated system the sum of all forms of energy is constant.

  6. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    In 1995 the USDA released a report stating that the net energy balance of corn ethanol in the United States was an average of 1.24. It was previously considered to have a negative net energy balance. However, due to increases in corn crop yield and more efficient farming practices corn ethanol had gained energy efficiency. [3]

  7. Energy budget - Wikipedia

    en.wikipedia.org/wiki/Energy_budget

    An energy budget is a balance sheet of energy income against expenditure. It is studied in the field of Energetics which deals with the study of energy transfer and transformation from one form to another. Calorie is the basic unit of measurement.

  8. Energy accounting - Wikipedia

    en.wikipedia.org/wiki/Energy_accounting

    Energy accounting is a system used in energy management systems to measure and analyze energy consumption to improve energy efficiency within an organization. [2] Organisations such as Intel corporation use these systems to track energy usage. [4] Various energy transformations are possible. An energy balance can be used to track energy through ...
