In spite of significant energy savings from efficiency in the residential sector since the year 2000 in many International Energy Agency (IEA) countries, it is often found that energy intensities of appliances (GJ/ dwelling) had either been kept at constant levels, or have even increased in this period and across different geographies. This is particularly relevant as residential appliances are the second-largest end use in IEA countries (after space heating), and diffusion of appliances like PCs more than doubled in this time frame.
The results found from the latest data of the IEA energy efficiency indicators database suggest that we need to set more ambitious energy efficiency policies if we aim at outpacing recent ownership patterns and decreasing intensity of residential appliances.
For these and more detailed insights (e.g. energy use and stocks by appliance type), as well as energy end use and activity data for other consumption sectors (residential, services, industry and transport) please see the newly released 2019 edition of the IEA energy efficiency indicators database with more recent data up to 2017. The IEA strives to release as complete and timely data as possible. In order to meet increasing user’s data needs, the IEA is releasing for the first time the energy efficiency indicators database in July, with the latest updates, based on availability.
The IEA energy efficiency indicators database will be updated again in December 2019, with more recent data and expanded geographical coverage, at the same time of the publication of the 2019 edition of the Energy Efficiency Indicators Highlights report.
