1: Own calculations based on data provided by the Working Group on Energy Balances (Arbeitsgemeinschaft Energiebilanzen) and the Rhineland-Westphalia Institute for Economic Research (RWI - Leibnitz Institute). Energy Balance data has been adjusted for temperature differences, heating oil data has additionally been adjusted for inventory changes. 3: Until 2010, energy consumption per household is based on national account data. Beginning in 2011, Census data is used. Results are therefore not entirely comparable . . = Numercial value unknow or not to be disclosed. | |||||||
