energiakulus
Energiakulus is a term used in energy accounting to describe the portion of input energy that is not converted into useful output within a system or process. It encompasses all forms of energy lost to inefficiencies, such as heat losses, friction, electrical resistance, transmission losses, and standby consumption. The concept helps assess how effectively a system uses energy and identifies opportunities for improvement.
Calculation is straightforward: if a device receives Ein of energy and delivers Eout as useful work or
Common examples include electric grids with line losses, heating, ventilation and air conditioning systems, engines with
Reducing energiakulus is central to improving energy efficiency and lowering operating costs and emissions. Approaches include
