KfW Energy Transition BarometerThe 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.
The energy transition is regaining momentum: households’ willingness to act themselves has risen – from 59% in the previous year to 66% now. The technology ramp-up is also progressing: around 14 million households, or 34%, use at least one green technology. Around 1.1 million households adopted one for the first time in the past year. Rooftop photovoltaics and electric vehicles are growing fast. By now, 53% of households have access to green electricity – up from 47% in the previous year.
Whether households participate in the transformation depends on income and housing tenure type: in the top income quartile, 51% use at least one green technology, in the bottom quartile 20%; in owner-occupied detached and semi-detached houses it is 59%, in rented flats 15%. For the transformation to reach all households, cost-effectiveness, targeted investment support and suitable information services remain decisive.
