Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…
2021
The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…
L'urgenza di un identikit
2015
L’idea di Millennials è nata, si è sviluppata e articolata, strutturandosi in modo ben più complesso da quelle che erano le istanze iniziali, intorno a una necessità: fotografare la scena della grafica italiana degli anni più recenti, focalizzandosi sulle produzioni di autori nati dopo il 1980. Il discrimine temporale nasce dalla constatazione di un cambio di passo, di una trasformazione radicale dovuta a più fattori: l’evoluzione tecnologica (è questa la prima generazione completamente digitalizzata), la crisi economica, che ha necessariamente imposto nuove modalità di produzione e di autorappresentazione, i percorsi formativi, strutturati da corsi di studi rivolti all’ambito disciplinare …
Environmental assessment of 2030 electricity generation scenarios in Sicily: An integrated approach
2020
Abstract This paper deals with the environmental assessment of two electricity scenarios in Sicily, for 2030, characterized by a high exploitation of renewable energy sources in order to quantify the potential contribution of the local strategies in the achievement of the European climate policies and the potential improvement in the future electricity mix, compared to the current one (2014). In order to match these goals, authors integrate the Life Cycle Assessment with a scenario analysis. The future electricity mix scenarios, characterized by a share of renewables (57% for 2030-BS scenario and 51% for 2030-DS scenario) show a reduction of the greenhouse gases emissions per kWh of electri…
Electric mobility in Sicily: An application to a historical archaeological site
2016
Transports should be a key focus in the close future for decarbonization efforts, if the optimistic climate change mitigation objectives to be reached by 2050 on a global scale are to be met. Choosing an emblematic and historical location in the center of Sicily as object of the study, the potential for decarbonization and the reduction of the energy and environmental impacts in the site for electric mobility is assessed, by considering electric mobility scenarios based on different shares of electricity generated through renewable energy technologies. The analysis is performed by means of a life-cycle approach, through the use of the Life Cycle Assessment methodology. A parametric analysis…
Life-Cycle Assessment Applied to Future Scenarios of Electricity Generation in Sicily
2018
Fighting global warming and increasing the energy security are some of the most relevant objectives of the European energy policy. Thus, defining potential low carbon pathways for the energy sector is of paramount importance in order to identify strategies with the lowest impact on climate. This paper presents an overview of environmental assessment of future electricity scenarios in Sicily (Italy), for 2020 and 2030, characterized by a high exploitation of renewable energy sources. Authors apply the Life Cycle Assessment methodology, according to the standard of the ISO 14040 series, in order to evaluate the environmental impacts of electricity generation in the future scenarios in compari…
Monitoring tropical forests under a functional perspective with satellite-based vegetation optical depth.
2020
Monitoring ecosystem functions in forests is a priority in a climate change scenario, as climate-induced events may initially alter the functions more than slow-changing attributes, such as biomass. The ecosystem functional properties (EFPs) are quantities that characterize key ecosystem processes. They can be derived by point observations of gas and energy exchanges between the ecosystems and the atmosphere that are collected globally at FLUXNET flux tower sites and upscaled at ecosystem level. The properties here considered describe the ability of ecosystems to optimize the use of resources for carbon uptake. They represent functional forest information, are dependent on environmental dri…

Risk profiles for re-profiling sovereign debt
2015
Purpose – This paper aims to use a risk management approach for re-profiling of sovereign debt. It develops profiles that trade off expected cost of financing alternative debt structures against their risk. The risk profiles are particularly informative for countries facing sovereign debt crisis, as they allow us to identify, with high probability, debt unsustainability. Risk profiles for two eurozone countries with excessive debt, Cyprus and Italy, were developed. In addition, risk profiles were developed for a proposal to impose debt sanctions in the Ukrainian crisis and it was shown that the financial impact could be substantial. Design/methodology/approach – Using scenario analysis, a r…
