The following definition applies

Energetic efficiency is a measure of the energy input required to achieve a defined benefit from products. The labeling of energy consumption for different products serves to support purchasing decisions. It provides information about energy efficiency during use (economic principle). A well-known example of this is the EU energy label for electrical appliances.

According to the EU regulation, for items with the indication of an energy efficiency class, a datasheet must always be provided.
