The core objective of this paper is to analyse the impact of changes in fuel intensity and car size on energy demand of passenger cars in EU-15 countries. Of special relevance in this context is how the rebound effect due to the change in car fuel intensity and car size (average engine power)...

A forced use of renewable energy sources (RES) is necessary to reduce greenhouse gas emissions significantly. Among RES biomass-based resources play a specific role regarding their CO2-reduction potentials, their energetic potentials and their overall costs for different derived energy carriers....

In the early 2000s high expectations existed regarding the potential contribution of biofuels to the reduction of greenhouse gas emissions and substitution of fossil fuels in transport. In recent years sobering judgments prevailed. The major barriers for a further expansion of biofuels are their...

The core objective of this paper is to analyze the energy and CO₂ reduction potentials as well as the market prospects of biofuels in EU-15 in a dynamic framework till 2050. The most important result of this analysis is that 2nd generation biofuels might become economically competitive between...

The objective of this paper is to analyze the impact of changes in fuel prices and fuel intensity (i.e. liters of fuel used per 100kilometers) on overall fuel (gasoline and diesel) consumption and on the demand for vehicle km driven in car passenger transport. This is important for deriving...

Virtually all goods and services that characterize modern societies' welfare depend on the provision of commercial energy. The core objective of this paper is to identify necessary changes in trends for achieving a transition towards more sustainable energy systems and development paths. The...
