Public acceptance of renewable energies in Bavaria using the example of biomass cogeneration plants and biogas plants

摘要

Decentral renewable energy supply requires a higher number of plants and affected residents since centuries.Despite many advantages, like e.g. reduction of greenhouse gases due to use of renewable energies, residents areconfronted with various emissions due to such plants. However, the turnaround to regenerative energy supply canonly be realized if citizens accept these new technologies in their neighborhood. This paper presents the findings oftwo surveys concerning public acceptance of biomass cogeneration plants (BCP's) and biogas plants (BGP's) inBavaria/Germany. Data was collected at 5,000 households in the neighborhoods of ten BCP sites and one BGP site.Results show a high level of public acceptance, lacking information among residents, almost no Not-in-my-Backyard behavior (NIMBYism) and essential differences between incentives and arguments of proponents andopponents of plants. Findings deliver useful information concerning project development to plant operators.
