"Approaching the Kyoto targets: a case study for Basilicata region (Italy) ",
No full textApproaching the national Kyoto Protocol (KP) targets involves a re-definition of the actual configuration of local energy systems. This study deals with a local scale application of the IEA-MARKAL models generator, in which the anthropogenic system of Basilicata Region (Southern Italy) is investigated to support the definition of coherent long-term strategies and sound climate protection policies. A scenario by scenario analysis points out the behaviour of the optimal mix of fuels and technologies in the presence of carbon dioxide emissions constraints. Trade off curves and reduced costs analyses outline the most effective actions for contributing to the national KP targets, with particular emphasis on the interventions in Civil (Residential, Commercial & Services) and waste management sectors.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
LCA and MDA for an integrated characterization of the technologies for electric energy production
No full textPower production systems are responsible for most local air pollutants as well as greenhouse gas emissions.
Renewable energy technologies allow one to reduce atmospheric pollution, but their total environmental impact (all life cycle phases) should be carefully assessed to avoid environmental degradation. Power production systems are responsible for most local air pollutants as well as greenhouse gas emissions. Renewable energy technologies allow one to reduce
atmospheric pollution, but their total environmental impact (all life cycle phases) should be carefully assessed to avoid environmental degradation. The aim of this
work was to characterise with a quantitative criterion the environmental impact of the in-use technologies for power production and to develop a methodology
based on a statistical approach that detects the cause-effect relationships. A general purpose methodology, based on the integration of LCA and MDA, was then implemented and applied for analysing the technological options provided
by the Energy Plan of Basilicata Region (Southern Italy). An inventory analysis of the air pollutants emitted by these technologies was carried out using LCA.
The inventory matrices were normalised and subsequently analysed by Cluster Analysis and Principal Component Analysis. In this way, the initial data were aggregated into statistically homogeneous groups and the principal components
were individuated, characterising the relationships between technologies and pollutants. The integration of the two methods allows for improvement of the informative content of LCA results, broadening its possible fields of application
A model for representing the Italian energy system: The NEEDS-TIMES experience
No full textSustainability of energy systems has a strategic role in the current energy-environmental policies as it involves key issues such as security of energy supply, mitigation of environmental impact (with special regard to air quality improvement) and energy affordability. In this framework modelling activities are more than ever a strategic issue in order to manage the large complexity of energy systems as well as to support the decision-making process at different stages and spatial scales (regional, national, Pan-European, etc.). The aim of this article is to present a new model for the Italian energy system implemented with a common effort in the framework of an integrated project under the Sixth Framework Programme. In particular, the main features of the common methodology are briefly recalled and the modelling structure, the main data and assumptions, sector by sector, are presented. Moreover the main results obtained for the baseline (BAU) scenario are fully descfibed
A REPRESENTATION OF THE SLOVENIAN ENERGY SYSTEM USING THE NEEDS TIMES MODEL
No full textThe relationships between anthropogenic activities and the environment require a careful analysis of economic and technological implication of energy-climate policies, to redirect the energy systems towards a sustainable configuration. This implies the implementation of innovative decisional tools for policy assessment to support the policy makers in the definition of effective energy-environmental strategies, coherent at different spatial scales. In this framework partial equilibrium models as the TIMES models generator, developed under the IEA-ETSAP Programme, represent a powerful tool to analyse global, national and local issues and to support the formulation of comprehensive policies. These tools are utilized in the framework of the Integrated Project NEEDS of the VI Framework Programme to implement a unique modelling platform, the Pan European NEEDS TIMES model, based on the integration of the energy system models of 30 EU countries, which are linked by energy and emissions trades. This paper is aimed to describe the NEEDS TIMES methodological approach in the Slovenia case study, providing a full picture of the actual national energy system and discussing the model indications for its development on a 50-year time horizon, based on a least-cost approach in an unconstrained (Business As Usual - BAU) scenari
Implementation of Positive Energy Districts in European Cities: A Systematic Literature Review to Identify the Effective Integration of the Concept into the Existing Energy Systems
Full text linkThe positive energy district (PED) is a rather recent concept that aims to contribute to the main objectives of the Energy Union strategy. It is based on an integrated multi-sectoral approach in response to Europe’s most complex challenges. But to what extent have its development and implementation been supported by research and innovation programs? And what is the state of the art of its implementation and effective penetration into the current energy systems of European cities, according to the evidence provided by the scientific literature? This study aims to investigate these issues, providing a critical overview of the PED situation by means of a systematic literature review based on the use of open-access bibliometric software supplemented with content analysis. The results show that less than half of the documents analyzed refer to actual case studies, 80% of which were funded as part of research projects. This seems to lead to the conclusion that although PEDs have been strongly encouraged by the scientific community and policy initiatives at the European level, their implementation in cities is still limited. Moreover, an uneven distribution among countries can be observed. To overcome the existing barriers to PED diffusion and implementation, it would be useful to provide more ad hoc funding and, above all, facilitate its accessibility also by municipalities not yet well integrated into European projects, initiatives, and networks
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
