Decision-Making Processes of Renewable Energy Consumers Compared to Other Categories of Ecological Products

In the scientific discourse on consumption, increasingly more attention is being paid to sustainable development. Regarding the fact that not only various types of enterprises, but also consumers contribute to the excessive consumption of natural resources, it is of crucial importance to reduce the knowledge gap in the field of sustainable consumer behavior and decision-making processes related to the choice of organic products. The paper aims to present the decision-making processes of Polish consumers of renewable energy against the background of other categories of ecological products. Special attention is paid to the extent in which the offer is adjusted to the needs of consumers of renewable energy in Poland, compared to other categories of ecological products. The paper also shows the perception of the consumer of ecological products by buyers of renewable energy and by people who do not buy ecological products. The paper is based on a literature review and the results of a quantitative empirical study. The quantitative research was performed on a nationwide sample of 1032 people, among whom 509 people bought an organic product in the last 3 months, and 523 people did not purchase such a product during this period. The analysis of the results allows us to conclude that in the case of renewable energy, factors such as price, quality and the producer’s certification play a crucial role in the decision-making processes of Polish consumers. The hierarchy of criteria considered in the decision-making process related to the purchase of renewable energy and equipment enabling the use of renewable energy sources is quite similar to the one observed when purchasing electric cars. At the same time, it should be noted that almost every second person purchasing renewable energy compares many offers and spends a relatively long time contemplating their choice

Maf1 Is Involved in Coupling Carbon Metabolism to RNA Polymerase III Transcription▿ †

RNA polymerase III (Pol III) produces essential components of the biosynthetic machinery, and therefore its activity is tightly coupled with cell growth and metabolism. In the yeast Saccharomyces cerevisiae, Maf1 is the only known global and direct Pol III transcription repressor which mediates numerous stress signals. Here we demonstrate that transcription regulation by Maf1 is not limited to stress but is important for the switch between fermentation and respiration. Under respiratory conditions, Maf1 is activated by dephosphorylation and imported into the nucleus. The transition from a nonfermentable carbon source to that of glucose induces Maf1 phosphorylation and its relocation to the cytoplasm. The absence of Maf1-mediated control of tRNA synthesis impairs cell viability in nonfermentable carbon sources. The respiratory phenotype of maf1-Δ allowed genetic suppression studies to dissect the mechanism of Maf1 action on the Pol III transcription apparatus. Moreover, in cells grown in a nonfermentable carbon source, Maf1 regulates the levels of different tRNAs to various extents. The differences in regulation may contribute to the physiological role of Maf1
