Ein moeglichst kostenguenstiges und oekologisches Heizsystem zu waehlen, ist fÜr Gebaeudebesitzer von größter Wichtigkeit. Bisher gängige Antworten sind jedoch spätestens seit diesem Jahr nicht mehr uneingeschraenkt gültig. Zum einen waren die Preise für Erdgas und Heizoel zuletzt starken...

In Germany and other Central and Northern European countries, energy demand for space heating dominates the energy demand of households. In line with European and national energy efficiency and emission reduction objectives, policy makers have identified the residential building sector...

The European energy policy is substantially driven by the target to reduce the CO2-emissions significantly and to mitigate climate change. Nevertheless European power generation is still widely based on fossil fuels. The carbon capture and storage technology (CCS) could be part of an approach to...

The German Energiewende envisages achieving a climate-neutral building stock in 2050 by means of two major pillars of regulation: First, residential buildings should consume 80% less primary energy and, second, the remaining energy demand should be covered primarily with renewables. This paper...

Ueber das Fuer und Wider einer Foerderung Erneuerbarer Energien mittels spezifischer Foerderinstrumente wie dem EEG sowie ueber die bestmoegliche Ausgestaltung dieser Instrumente sind in den letzten Jahren viele sowohl praxisorientierte als auch wissenschaftliche Debatten gefuehrt worden. Dabei...

In principle, portfolio optimization in electricity markets can make use of the standard mean-variance model going back to Markowitz. Yet a key restriction in most electricity markets is the limited liquidity. Therefore the standard model has to be adapted to cope with limited liquidity. An...

Small decentralized power generation units (DG) are politically promoted because of their potential to reduce GHG-emissions and the existing dependency on fossil fuels. A long term goal of this promotion should be the creation of a level playing field for DG and conventional power generation....

Optimal capacity allocation for investments in electricity generation assets can be deterministically derived by comparing technology specific long-term and short-term marginal costs. In an uncertain market environment, Mean-Variance Portfolio (MVP) theory provides a consistent framework to...

Natural gas storages may be valuated by applying real options theory. However it is crucial, not to ignore that most evolving gas spot markets, like the German spot market, lack of liquidity. In this context, considering storage operators as price takers does not account for interdependencies of...

The efficiency of capital markets has been questioned almost as long as the efficient market hypothesis had been worked out. Numerous critics have been formulated against this hypothesis, questioning notably the behavioural assumptions underlying the efficient market hypothesis. The present...
