The risks associated with current and prospective costs of different energy technologies are crucial in assessing the efficiency of the energy mix. However, energy policy typically relies on the evolution of average costs, neglecting the covariances in the costs of the different energy...

This paper studies the change in Energy Intensity (<i>EI</i>) of the main economic activities in the EU15 countries, which represents approximately 45% of their final energy consumption. The purpose is, first, to measure the different patterns between the countries by establishing differentiated...

The main purpose of this paper is to assess efficiency of the Brazilian electricity generation mix proposed in the 2020 Decennial Plan for Energy Expansion (DPEE 2020). It evaluates estimated costs, risks and CO2 emissions following the mean–variance portfolio theory. The efficiency frontier...

Este trabajo estudia la evolución del índice de intensidad energética (IIE) de los principales sectores de actividad (primario, industria, construcción y servicios) en la UE-15 entre 1991 y 2005. Para cada país, realizamos una desagregación amplia de los sectores económicos y sus consumos...

This paper estimates changes in the productivity of the Brazilian electricity distribution sector using Data Envelopment Analysis (DEA) on a panel of 18 firms from 1998-2005. The study decomposes the productivity change of these distribution firms in terms of technical efficiency;...

The objective of this paper is to chart the productivity of Spanish port terminals, which are private firms under concession and can be regarded as representative of medium size firms worldwide so as to evaluate the effects of different regulatory reforms applied in the 1990s. We perform a...

This study analyzes customers' preferences and their willingness to pay (WTP) for certain service attributes in an electricity supplier choice context. Specifically, a stated preference choice experiment is conducted in the Canary Islands' residential market where limited competition exists....
