Table 3: Monthly data of the German market from 2013 to 2020 used to predict the results. The model presented in this paper has confirmed that increased electricity efficiency during the last decade was responsible for lower consumption values relative to what would have been otherwise expected. This increase in the efficiency of electricity usage is probably related to the environmental actions of the EU during the last decade. These have been observed in many areas of business and household management, such as the development of engines with lower consumption, buildings insulation, more efficient equipment, and more emphasis put by individuals on energy savings. A more detailed study on the contributions of different areas to the total energy efficiency usage increase is not a part of this article.
