energiuttag

Energiuttag is a term used in Swedish energy research and planning to denote the total amount of energy drawn from a system, resource, or service by a user, process, or sector over a specified period. It describes energy demand or consumption rather than energy production and can cover electricity, heat, fuels, and other energy carriers.

In practice, energituttag is used to quantify the energy demand of households, buildings, industry, transport, and entire economies. It serves as a key input in forecasting, infrastructure planning, and efficiency measures. Analysts compare energyuttag with energy production to assess energy balance, self-sufficiency, and the need for capacity additions or policy interventions.

Measurement and methodology commonly involve units such as joules, kilowatt-hours (kWh), megawatt-hours (MWh), or terawatt-hours (TWh) at larger scales. Defining the scope and system boundaries is essential: which energy carriers are included (electricity, gas, oil, heat), the time interval, and the level of aggregation (facility, region, country). Data sources may include metering, energy bills, surveys, and national statistics. Exergy analysis can be used to evaluate the quality of energy flows within the measured energituttag.

Relation to other concepts: energituttag differs from energy production, which is the supply of energy, and from energy efficiency, which concerns reducing the energy needed for a given service. It is closely related to energy use, energy consumption, and energy intensity, and its interpretation depends on system boundaries and policy context.
