Energy efficiency


 
The energy efficiency class supplies information on the energy consumption of technical devices, buildings or automobiles. The energy efficiency classes were classified into different categories and named based on the American school grading system, with "A" being the best energy efficiency class (low consumption) and "G" describing the highest consumption level. The scale for quality category A was already defined in 1994 and it corresponded to the latest technological standards at the time of realisation. In order to be able to reflect new technological developments, in particularly with regard to electrical and household appliances, additional efficiency classes (A , A , A ) were introduced for some products such as refrigerators, washing machines or TVs.
 

Costs and savings potential of light sources

The following table provides an overview of the costs as well as the savings potential of different illuminants in comparison to conventional incandescent lamps. The column "Savings per year" contains the amount that can be saved when using the respective illuminant. The "energy costs per year" for the conventional incandescent lamp are used as reference value.
