Consequences of warm utility costs: impact analysis of current and future heating costs for private households, energy suppliers and housing companies

Initial situation

In Germany almost half of all homes are heated with natural gas. As a result of the Russian war of aggression on Ukraine, the supply of natural gas from Russia has been drastically reduced, which has led to a significant increase in the price of natural gas. End consumer prices for natural gas, as well as for oil and electricity, are currently significantly higher than in 2021.

The increased prices have a different impact on different private households. In addition, households can also react in different ways (reducing consumption, investment in new heating systems etc.) Large differences can be observed here not only by not only by household income, but also between households in rental housing and those in owner-occupied housing. In addition to private households energy providers as well as landlords are affected by the changed conditions and may have to make adjustments.

Aim of the project

The aim of the research project is to consider the effects but also the adaptation reactions to the increased energy prices. In all considerations, different groups of private households, energy providers and housing associations are to be distinguished. Within the scope of the overall project, the following research questions are to be answered.

Subsequently, recommendations for action are to be derived:

To what extent and in what way are further support measures necessary or which measures should be adapted or changed?What future energy price increases can be expected and how should energy price increases be responded to in the future? How can the "heat transition" (Wärmewende) be implemented in a socially responsible way?
