Austria aims at increasing its share of renewable energy production by 11% until 2020. Combined Heat and Power (CHP) plants fired by forest wood can significantly contribute to attaining this target. However, the spatial distribution of biomass supply and of heat demand limits the potentials of...

Ambitious renewable energy targets have been implemented in the EU that can only be attained if further measures are taken to boost biomass production for energy uses on agricultural land. The aim of this discussion paper is to explore consequences for land use and environment if biomass...

Während der EU-Schuldenkrise wurde einigen Staaten unterstellt, sie seien insolvent. Können Staaten aber tatsächlich Bankrott gehen? Der Autor hält einen Vergleich von Staaten mit Unternehmen für unzulässig. Solange ein Staat sich in eigener Währung verschuldet, kann er sich durch...

Effective visualisations of migration flows can substantially enhance our understanding of underlying patterns and trends. However, commonly used migration maps that show place-to-place flows as stroked lines drawn atop a geographic map fall short of conveying the complexities of human movement...

A high share of Brazilian power production comes from hydropower sources. A further expansion of power generation is necessary due to high growth rates in electricity demand. As an alternative to carbon intensive thermal power production and the expansion of hydropower in the ecologically and...

Brazil has to quickly expand its power generation capacities due to significant growth of demand. Government plans aim at adding hydropower capacities in Northern Brazil, additional to wind and thermal power generation capacities. However, new hydropower may affect environmentally and socially...

Low emission prices have stirred up discussion about political measures that aim to increase emission prices. District heating system operators, often municipal utilities, use a variety of heat generation technologies that are affected by the emission trading system. We examine whether district...
