摘要

China has committed to reduce energy and CO_2 intensitythrough 2020 but whether and how specific energy efficiencymeasures can help achieve these goals is unclear. One area withsignificant energy and emissions reduction potential is residentialend-uses, as urbanization and rising incomes continue todrive household ownership, usage and demand for residentialenergy services. However, because China only recently startedfocusing on energy efficiency and has followed an iterative regulatoryapproach to raising equipment efficiency levels, thereis significant remaining – but not yet quantified – technicalsavings potential from residential end-use efficiency improvements.In this paper, we evaluated the technical potential of maximizingChina’s residential equipment efficiency and the subsequentenergy demand and CO_2 emissions implicationsthrough 2030. A detailed LBNL bottom-up, end-use energymodel is used to highlight residential end-use energy linkagesbetween urbanization, economic development and China’sgrowing buildings sector. Scenario analysis with a referenceenergy efficiency scenario and a maximum technically feasibleefficiency improvement (Max Tech) scenario is used toevaluate two possible pathways of energy and emissions reductionand the efficiency gap by residential end-use through2030. Relative to the reference scenario, achieving Max Techresidential efficiency improvements could save 3.91 EJ and395 million tons of CO_2 per year by 2030. Energy savings opportunityvaries across end-uses, with major appliances havingthe largest savings potential despite a smaller share of totalenergy demand followed by space heating and cooking efficiencyimprovements. Electricity savings and the associatedCO_2 reduction from equipment efficiency improvements canbe magnified by power sector efficiency improvements andfuel switching, underscoring the dual importance of end-useefficiency improvements and power sector decarbonizationin China’s future.
