Energy efficiency means the contribution of energy consumption which keeps and promotes the sustainable development of the whole Economic-Social-Environmental system. Energy efficiency is usually the ratio of energy output service to energy input. Because of the different method for different department to deal with the energy output service and energy input, there exists different energy efficiency measurement.
This briefing intends to introduce each energy efficiency, includes energy macro-efficiency, energy substantial efficiency, energy physical efficiency, energy factor-utilization efficiency, energy factor-allocation efficiency, energy value efficiency and energy economic efficiency.
