Mapping Seasonal Variability of Buildings Electricity Demand profiles in Mediterranean Small Islands
2023
In communities with a high tourist influx and warm climate, such as Mediterranean small islands, the energy demands for space cooling and domestic hot water are expected to significantly increase during summer. Considering the current energy context, for succeeding energy transition and reducing the dependency on not endogenous fossil fuels, it is paramount to increase the deployment of renewable sources of energy, especially wind and solar which, however, are aleatory and unpredictable. Hence, to reduce the high costs for energy supply in these contexts, the analysis of the variation of energy consumption is fundamental. Moreover, mapping the spatial distribution of energy profiles can be …
Sulla presenza di Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae) nella Riserva Naturale di Isola delle Femmine (Palermo, Sici…

[On the presence of Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae) in the Nature Reserve of Isola delle Femmine (Palermo, Sicily, Italy)] The presence of a living population of Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae), endemic species of the coastal strip of the Palermo Mountains (Sicily), from Isola delle Femmine or Isola di Fuori (Isola delle Femmine Nature Reserve) is confirmed
System Stability of a Small Island's Network with Different Levels of Wind Power Penetration
2018
The reduction of the inertial response of the generation system has been one of the main obstacles to the penetration of high sharing of renewable energy sources in islanded systems. This issue can be solved thanks to innovative control that makes wind turbines able to provide the so-named synthetic inertia. The paper investigates some scenarios with different levels of wind power penetration in a small island whose grid is not supplied by the main grid, by the use of the software NEPLAN 360, simulating the wind power plants accordingly to the standard IEC 61400-27. The aim of the paper is to assess the maximum level of penetration in the island of wind generation, with traditional control …
An Economic Approach to Size of a Renewable Energy Mix in Small Islands
2022
The importance of renewable energy exploitation reduces the energy dependence on fossil fuels. Despite technological progress, in several remote areas and small islands the energy production is nowadays dominated by the utilization of fossil fuels. With new, increasingly stringent laws on polluting emissions and the need to lower production costs, it is necessary to exploit as many renewable sources as possible. In order to implement these considerations, it was decided to study renewable energy production. The study was carried out by estimating the energy production on a monthly and annual basis considering a mix of three plants, namely marine, solar, and wind. Simulations on wave product…
Characterization of a small Mediterranean island end-users’ electricity consumption: The case of Lampedusa
2017
Abstract The paper presents the results of a study carried out on Lampedusa Island (Italy) and based on the survey of electricity consumption data. The main outcomes of the study are: • the characterization of the energy demand of private houses and hotels in Italian small islands with significant touristic flows during the summer period; • the identification of inefficient use of the electric loads; • the construction of aggregated load profiles for clusters of homogeneous domestic end-user to be used for implementing Demand Response strategies. The study shows how electricity consumption in Mediterranean small islands are very high with respect to the national average and lays the basis f…
A renewable energy mix to supply small islands. A comparative study applied to Balearic Islands and Fiji
2019
Abstract Power plants supplied by renewables are expanding around the world, increasing the sustainability of the energy sector. In this context, small islands are heavily reliant on fossil fuels. However, this paper shows that the same problem can be found also in small islands belonging to developed countries. To increase the energy sustainability of small islands, the authors assembled a simplified mathematical approach to evaluate the potential electricity production, exploiting the local available energy sources: solar, wind and sea wave. The mathematical model requires few information in input, such as climatic data about the local energy sources and technical features on the selected…
Wave Energy Assessment and Performance evaluation in Mediterranean Sea
2020
The paper proposes a revolutionary device for the utilization of a new entry of renewable energy sources: sea wave. This technology is based on linear generators, able to converts directly a linear motion into electrical output, limiting to minimum the chain of energy conversion. A preliminary feasibility assessment considers a case study applied in Lampedusa, a small island in the Mediterranean Sea. Economic and environmental evaluations are here reported.
Insurance mechanisms for tropical cyclones and droughts in Pacific Small Island Developing States
2016
One group of locations significantly affected by climate-related losses and damage is the Small Island Developing States (SIDS). One mechanism aiming to reduce such adverse impacts is insurance, with a wide variety of products and models available. Insurance for climate-related hazards affecting Pacific SIDS has not been investigated in detail. This article contributes to filling this gap by exploring how insurance mechanisms might be implemented in the Pacific SIDS for tropical cyclones and droughts. The study examines opportunities and constraints or limitations of some existing insurance mechanisms and programmes as applied to the Pacific SIDS. Eight insurance mechanisms are compared and…
A sustainable energy production: Sea Wave in the small island of Ustica (Italy)
2018
Nowadays the electrical energy production is based on fossil fuels in the greatest part of smaller islands in the Mediterranean Sea. Despite the availability, the renewable energy sources are practically unused, as landscape constraints. So, the paper presents the case of study of Ustica, a small island located at north of Sicily, in the middle of Mediterranean Sea. Starting with the analysis of the electrical energy consumption of public buildings, the paper suggests an energetic scenario, based on solar and sea wave. In particular, in order to use this new resource, the paper presents an innovative wave energy converter. Finally, the energetic and economic evaluations encourage the realiz…
Evaluation of the optimal renewable electricity mix for Lampedusa island: The adoption of a technical and economical methodology
2020
Abstract Worldwide, the majority of small islands not connected to the main grid is still dependent on fossil fuels. From an economic and environmental point of view, this condition is no more sustainable given the high costs for electricity generation and the high level of pollutant emissions. Furthermore, the dependence on fossil fuel represents a risk for the security of the supply of several small developing Countries since they are obliged to import those resources from foreign Countries. The introduction of renewable energy sources in small islands represents a valid solution to solve these problems. In this context, the paper investigates the case of Lampedusa, a small Italian island…
