PublicationBalancing the books: unveiling the direct impact of an integrated energy system model on industries, households and government revenues( 2024)
;Marx, AlexanderBackground: The transition towards a sustainable energy system is reshaping the demand for final energy, driven by the diffusion of new end-use technologies. This shift not only impacts consumers’ energy expenses, but also holds implications for the public budget. Building on data from a German energy transition scenario, we analyse the direct impact of energy costs on industries, low-income households, and changes in government revenues from the taxes and levies on final energy carriers. Our analysis considers the impact of current policies and explores a scenario introducing additional excise tax rates to offset potential revenue losses. Results: We found that substantial carbon price increases could generate revenues that offset the losses from excise taxes on fossil fuels while enabling the financing of renewable support from the public budget by the end of this decade. Nevertheless, a decline in government revenues from taxes and levies is anticipated after 2030 until the middle of the century due to the declining use of fossil fuels. Maintaining current excise tax revenues during the transition could be achieved by introducing additional excise taxes on fossil fuels and electricity. Lastly, our analysis indicated a continuous decline in household energy expenditures until 2050, whereas energy-intensive industries face adverse impacts due to decarbonisation. Conclusions: This research provides valuable insights into the fiscal implications of the energy transition, shedding light on different industrial sectors and households while considering the evolving impact on the public budget. Policymakers may need to consider systemic reforms or alternative financing mechanisms outside the energy system to balance the books. -
PublicationThe landlord-tenant dilemma: Distributional effects of carbon prices, redistribution and building modernisation policies in the German heating transition( 2023)A carbon price on heating fuels aims to reduce the use of fossil energy in the heating sector. However, it has a greater effect on tenants than on landlords. The heating transition requires adequate building insulation for efficientuse of low-temperature technologies. To encourage this particular kind of investment, German landlords are given the option to apply a modernisation levy of up to 8% on top of rents. Similar to carbon pricing, rent increases cause distributional effects. The net effect of these measures on tenants has not been analysed so far. Using a micro-simulation integrating representative empirical data on tenant households in Germany from KOSMA and the detailed building database TABULA, we analyse direct distributional effects of a carbon price (€55/t and €250/t), a per-capita redistribution of carbon price revenues and the modernisation levy (8% and 2% rent increases). The analysis shows that carbon prices and modernisation levies have strong regressive effects. These can be mitigated by the per-capita redistribution. However, the effect on tenants within a given income decile varies largely due to the diversity of buildings. Thus, when designing and evaluating policies, looking at average effects is not sufficientto assess economic impacts for individual households.

Publication7 Empfehlungen zum Gelingen der Energiewende(Fraunhofer-Gesellschaft, 2021)Die verschärften europäischen Klimaschutzziele und das neue deutsche Klimaschutzgesetz sind sehr ambitioniert und erfordern drastische und sofortige Maßnahmen. Zur Frage, wie diese am besten ausgestaltet sein sollten, hat das Fraunhofer Cluster of Excellence Integrated Energy Systems (CINES) sieben Empfehlungen für ein Gelingen der Energiewende erarbeitet.
