Summary/Abstract

This paper quantifies the direct rebound effects associated with the switch from incandescent lamps (ILs) or halogen bulbs to more energy efficient compact fluorescent lamps (CFLs) or light emitting diodes (LEDs) using a large nationally representative survey of German households. The direct rebound effect is measured as the elasticity of energy demand for lighting with respect to changes in energy efficient lamps. In particular, the rebound effect is decomposed into changes in lamp luminosity and burn time. For the average bulb, the associated total direct rebound effect is estimated at about 6%. The larger part (around 60%) of this rebound effect results from increases in bulb luminosity. For the most frequent (modal) bulb switch, i.e. the replacement of the main bulb in the living or dining room, the total direct rebound effect is just below 3%, with around 60% attributable to an increase in burn time. Average and modal bulb differences suggest that the magnitude of the rebound effect may decrease with intensity of initial bulb use. The magnitude of the direct rebound and the relative contributions of changes in luminosity and burn time also differ by initial bulb type and by replacement bulb type.

Summary/Abstract

Carbon pricing is a policy instrument that is very popular with researchers and many policy makers as well. To be implemented effectively, it requires widespread acceptance by society. This paper presents an empirical study carried out in Germany directly before the implementation of its new carbon-pricing scheme for fuels in 2021. The empirical study with 83 participants focused on how different revenue use options were perceived by population groups that are particularly burdened by carbon pricing: single parents with commutes, social welfare recipients, long-distance commuters as well as pensioners with large homes. The study applied a mixed methods design involving focus group participants also completing questionnaires. The findings show a good level of acceptance of carbon pricing in view of the need to mitigate climate change and the widespread expectation that the revenues will be used to achieve this. The preferred option for revenue use are public investments in sustainable transport and climate protection. Overall, the topics discussed were often perceived as complex. The paper concludes by recommending policy makers to use combinations of revenue uses and to ensure that the overall impacts of carbon pricing and revenue use are visible to the public.
