Prioritizing energy conservation and controlling total energy consumption by improving comprehensive energy efficiency are the basic principles of energy revolution

and also the im portant prerequisites for promoting energy structure optimization and upgrading

leading green and lowcarbon transformation

strengthening energy security and achieving high-quality energy development. Firstly

the progress of energy intensity and consumption “double control”is analyzed

as well as the coming situation and challenges. Secondly

the new missions of energy conservation and comprehensive energy efficiency improvement in the new era are put forward

including 3 aspects of promoting energy transformation

building ecological civilization and expanding new momentum of green development. Finally

the ideas and approaches of energy conservation and improving comprehensive energy efficiency in the “14th Five-Year Plan”period are discussed from the aspects of systematic optimization

multidimensional collaboration and synthetical integration. It can be concluded that

in the“14th Five-Year Plan”period

the efficiency of energy system must be greatly improved

and the control and management for total energy consumption should be implied

especially fossil energy consumption. The strategic position of energy conservation and comprehensive energy efficiency also should get enhanced

and the energy conservation should fully play the role as“the first energy”.
