Background In order to achieve an environmentally friendly and sustainable energy supply, it is necessary that this goal is supported by society. In different countries worldwide it has been shown that one way consumers want to support the energy transition is by purchasing green electricity. However, few people make the leap from their intention to a buying decision. This study explores parameters that influence whether German consumers decide to switch to a green electricity tariff. Methods We conducted a quota-representative online survey including a discrete choice experiment with 371 private households in Germany in 2016. For the econometric analysis, a generalized multinomial logit model in willingness to pay space was employed, enabling the estimation of WTP values to be as realistic as possible. Results The results show that consumers’ decision regarding whether or not to make the switch to green energy is mainly influenced by the source of green energy, whether a person can outsource the switching process, and a person’s attitude towards the renewable energy sources levy that currently exists in Germany. Conclusions As our findings indicate politics should focus on supporting wind and solar energy as German consumers prefer this sources over biogas. As suggested by our results, the EEG levy is a reason why consumers have lower WTP for a switch to a green tariff. Therefore a switching bonus with a specifically “framed” bonus in the amount of the current EEG levy could be a promising strategy for the increase of green energy tariff acceptance. Furthermore, attention should be given to psychological and behavioral aspects, as our results indicate that these factors influence the consumer’s choice for a green electricity tariff.

“…The sugar market in the European Union was a regulated market since 2006, and sugar beet producers were subject to production limits [1]. From 1 October 2017, the existing regulations on the EU sugar market have ceased to apply [2]. Liberalization of the sugar market has increased farmers' interest in sugar beet production.…”

The usefulness of sugar beets for biogas production in relations of the storage time and sugar content

The aim of the study was to evaluate the usefulness of sugar beet for biogas production, taking into account the duration time of storage and sugar content in the roots. The research has included analysis of methane and biogas yield of sugar beet. The relations between the sugar content in the roots and the length of storage period and the course of the methane fermentation process were determined. Sugar beets with sugar content of 17.6% and 19.6% were used for this experiment. In order to analyse the fermentation process, the fresh beets and the beets stored in flexible, hermetic tanks in the period of 43 and 89 days were used. Based on the analysis of the obtained results, it was found that the sugar content and the storage time of sugar beet roots can differentiate the production of biomethane and that it influences the methane fermentation process and the quality of the produced biogas.

Abstract:In an effort to support the long-term viability of the bioenergy industry through an end market for digestate, we investigated purchasing preferences for fertilizer product features in the home gardening market. We conducted a discrete choice experiment (DCE), presenting 504 respondents with a total of 6048 product attribute choices in a simulated context that replicated the tradeoff decisions made in the real marketplace. We analyzed the choice data using a hierarchical Bayes estimate to generate part-worth utilities for fertilizer product attributes. We then conducted a latent class analysis to identify market segments that could be expected to respond to differentiated product design strategies. We were able to quantify both purchasing preferences for fertilizer product attributes as well as the importance of each attribute to the perceived utility of a product. We were further able to identify five distinct market segments that make clear the potential for differentiated strategies in the home gardening market. We found both negative and positive price sensitivities, with sociodemographically distinct subgroups that favored low-, mid-, and high-priced products. We also found purchasing preferences for brand status, product labeling and nutrient values. Our results provide insights that should help product managers in the biogas industry develop marketing strategies to integrate digestate into a sustainable energy production system.
