| 1: Own calculation based on data provided by the Working Group on Energy Balances (Arebeitsgemeinschaft Energiebilanzen) and RWI - Leibnitz Institute for Economic Research. Energy Balance data has been adjusted for temperature differences, heating oil data has additionally been adjusted for inventory changes. 2: Including communication. 3: Data as in the national energy balance, but without energy use of commercially used spaces in private households of self-employed persons. 4: Source: Microcensus 2022 (household at primary residence). The comparability of the time series before and after 2011 is limited due to the extrapolation change. The information represents a revision compared to previous editions of "Private Households and Environment". As a result, all information per household in this publication has also been revised.
