Technical, economic, and social need to define and control the efficiency of energy usage – consumer energy efficiency implies the necessity to determine the exact contents of this new concept. A deeper analysis of a consumer energy system in order to support the consumer energy efficiency value appropriate for the contents should be carried out to find the factors that affect the value. This article shows that for the purposes of advanced energy consumption analysis, the consumer energy system becomes an integral part of the whole energy system (starting with the energy generation facility) which forms the demand for the produced energy and its usage efficiency. The consumer energy system is so important that in the course of developing and improving the electric supply and consumption systems, it questions the traditional priority of the first component (energy supply) and adaptive dependence of the second one. This article proves, inter alia, that manufacturers can raise their consumer energy efficiency by improving the production technology, using materials with new properties, modernizing the energy equipment, switching to automatic enterprise design systems and using other means commonly known as scientific and technical progress.
