The research project asked how increasing energy costs and hence increasing costs for mobility affect a growing number of poverty households. Furthermore, the project searched for solutions how the people concerned can be enabled to reduce their energy and resource consumption with the help of a more efficient and sustainable way of consuming. It was revealed that increasing energy costs are a growing problem for poverty households. Particularly heating costs of Hartz IV-claimants are more and more only partly covered with social benefits. At the same time, the group concerned is often hardly informed about ways how to reduce costs and about amortisation periods of technical devices.
