【 摘 要 】

Energy problem has been the focus of attention. Energy efficiency evaluation is an important part of energy conservation and emission reduction, but the evaluation system of energy saving measures and its effect is not perfect. Firstly, a more perfect and scientific energy efficiency evaluation system is established. The kinds of energy are classified. The concepts of extended system, global system, transfer extended system and local extended system are put forwarded. The connection of the two energy efficiency evaluation indices, energy consumption ration and energy utilization efficiency, was analyzed. On this basis, the concept of energy consumption transfer and energy consumption feedback is introduced, and its significance is expounded.
