Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for...

According to the official document of Romania's energy policy for the period 2020-2030, with a view to 2050, the main objective of the strategy is to increase the energy sector in conditions of sustainability by setting targets for reducing greenhouse gas emissions and promoting renewable...

In recent years, bioeconomy strategies have been implemented and adapted internationally. In the bioeconomy, materials are to a certain extent circular by nature. However, biomaterials may also be used in a rather linear way. Lately, a transition towards a circular economy, a more restorative...

This study describes the relationship between GHG emissions and a set of economics and environmental variables in the energy sector of the 27 Brazilian states, during the period 2010 to 2020. The system Generalized Moments Method (system GMM) was used to verify the influence, in particular, of...

This paper summarizes the main findings of the results in the literature on the role of ethanol in reducing retail gasoline prices in the United States. We provide a comprehensive overview of the key results and methodologies used to obtain them. The paper documents the growing research interest...

We analyze the relationships within the liquid fuels system and its associated supply chain using innovative network filtering methods, namely the Minimum Spanning Tree and Triangulated Maximally Filtered Graph. Our findings reveal that biofuels form robust connections with their feedstocks that...

Vorliegender Bericht gibt einen Überblick über den Stand und die Projektionen der globalen Landnutzung sowie der Nahrungs- und Futtermittelversorgung bis 2050, wobei die Frage im Mittelpunkt steht, ob zum einen die wachsende Bevölkerung ernährt werden kann und zum anderen, welche...

Dieser Aufsatz argumentiert, dass die deutsche EE-Förderung auf einer falschen Konzeption beruht. Sie hat sich vorwiegend befehlswirtschaftlicher Methoden bedient und eine Staatsschuldillusion zu erzeugen versucht. Es verwundert infolgedessen nicht, dass enorme Kosten entstanden sind,...

Biofuels and other forms of bioenergy have received increased attention in recent times: They have partly been acclaimed as an instrument to contribute to rural development, energy security and to fight global warming but have been increasingly come under attack for their potential to contribute...

It is still difficult for biofuel producers to proof the contribution of their biofuels to reducing carbon emissions because the production of biofuel feedstocks can cause land use change (LUC), which in turn causes carbon emissions. A carbon map can serve as a basis to proof such contribution....
