    KfW Energy Transition Barometer

    The KfW Energy Transition Barometer is a study conducted annually since 2018 on the basis of a survey of a random sample of some 4,000 representative households in Germany. Responses from each household were received from one household member of full age who takes decisions on household energy supply and consumption. The aim of the survey was to find out to what extent energy transition technologies are being used in the different households. The survey also covered any planned use in order to estimate in what areas the greatest growth was to be expected. Taken together, the surveyed data provide an overview of current sentiment and households’ participation in the energy transition in Germany.

    Support remains stabile – one in three households uses green technologies

    In many countries, stronger climate action is becoming less of a priority. After moderate declines in recent years, support for the energy transition in Germany has grown slightly again. According to the KfW Energy Transition Barometer, 83% of households consider the energy transition to be important or very important, up from 82% last year. In contrast, the share willing to take action themselves has dipped slightly to 59%.

    Overall, 13.5 million households (33%) use at least one green technology – an increase of around 800,000 households, or about two percentage points, on the previous year. Green technologies include for example heat pumps, photovoltaic systems and electric vehicles. Cost-effectiveness is crucial for uptake; rising fossil fuel prices under the EU-ETS2 could support future adoption.
