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...

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;...

This paper estimates the productivity evolution of the Brazilian electricity distribution industry decomposing it in terms of technical efficiency, scale-efficiency and technical change. This exercise aims to understand one important issue that has not been analyzed in previous papers, that is...

The Canary Islands offer an example of an isolated electric grid of relative important size within the EU. Due to its peculiarities, the role of renewable energies and their complementarity with fossil fuels offers a solid path to achieving the main energy policy goals of the Islands. The...

Buena parte del diseño de política energética actual se centra en el estudio individual de los costes de las diferentes opciones tecnológicas de generación de electricidad. En este artículo mostramos que el riesgo asociado a los costes de generación para las distintas tecnologías...
