The nonmarket benefits of redeveloping dockland areas for recreational purposes: the case of Castellón, Spain
2003
As a consequence of the decline of central harbour sites and the relocation of port activities to the outskirts of cities, today waterfront redevelopment has become a key issue in the urban revitalisation policies of port cities. Although we are aware that city-port regeneration has strong links with the real estate market, our purpose here is very different. In particular, the contingent valuation method (CVM) has been applied in order to obtain the nonmarket benefits of the environmental and urban improvements derived from redeveloping some port-related areas for recreational and leisure purposes in the city of Castelloèn, Spain. To date, no previous study has attempted to apply this meth…
Estimación del valor económico de la calidad del agua de un río mediante una doble aproximación: una aplicación de los principios económicos de la Di…
2011
El principal objetivo de la Directiva Marco del Agua de la Unión Europea es logar un “buen estado†de las aguas europeas para el año 2015 mediante una combinación de diferentes medidas. En este estudio, dos métodos de preferencias declaradas, el método de valoración contingente y el método de ordenación contingente, han sido aplicados para obtener la valoración económica de una hipotética mejora de la calidad del agua de un río. La comparación de las dos metodologías muestra que las valoraciones obtenidas con el método de ordenación contingente son considerablemente mayores que las obtenidas con la valoración contingente. Por último, los valores estimados se agregan para obtener una apro…
Review of potential and actual penetration of solar power in Vietnam
2020
With the average solar radiation reaching up to 5 kWh/m2, Vietnam is considered as a country showing an excellent potential for solar power production. Since the year 2000, there have been a lot of studies about the potential of this source in Vietnam. So far, many applications of solar power have been implemented on small, medium, and large scales. In fact, the total capacity of current grid-connected solar power plants has exceeded the planned capacity by 2020 nearly 6 times. However, the studies of solar potential in Vietnam are still incomplete. The policies and mechanisms for developing solar power projects have received attention from the authorities but have not been really satisfact…
The Recent Change in the Italian Policies for Photovoltaics: Effects on the Energy Demand Coverage of Grid-Connected PV Systems Installed in Urban Co…
2016
In July 2013, the Italian photovoltaic (PV) support policies changed the feed-in tariff (FIT) mechanism and turned to a tax credits program, which is currently in force. The aim of this paper is to investigate how such a radical change has influenced the electricity demand coverage of the PV systems installed in urban contexts. A methodology, which connects the economic assessment to a detailed architectural and energy suitability analysis, was applied to some case studies to analyse the relationships between the physical parameters related to multi-storey buildings (roof shapes, number of floors and area of flats) and the most relevant economic and financial features affecting the viabilit…
A Conceptual Review on Using Consequential Life Cycle Assessment Methodology for the Energy Sector
2020
Energy is engaged in the supply chain of many economic sectors; therefore, the environmental impacts of the energy sector are indirectly linked to those of other sectors. Consequential life cycle assessment (CLCA) is an appropriate methodology to examine the direct and indirect environmental impacts of a product due to technological, economic or social changes. To date, different methodological approaches are proposed, combining economic and environmental models. This paper reviews the basic concept of CLCA and the coupling of economic and environmental models for performing CLCA in the energy sector during the period 2006–2020, with the aim to provide a description of the different tools, …
Efficacy and Efficiency of Italian Energy Policy: The Case of PV Systems in Greenhouse Farms
2014
The production of energy from renewable sources is a form of energy production that has less impact on the environment than the traditional one. For the farmer this new form of production represents an opportunity, especially for the economic benefits that can produce, both in terms of the incentives provided by the public operator and for higher revenues, deriving from the sale of energy back to the grid and/or the savings generated by self-consumed energy, that help to increase the farmer’s income. In this paper, we analyzed a case study of a farm that has realized a grid-connected photovoltaic (PV) system on a greenhouse. In particular, firstly the farm profitability has been estimated a…
Saving Process within a Zero Waste Strategy In Sicily: A System Dynamics Approach
2018
Disposable society represents a way of living that is not sustainable anymore, mainly in a context like our planet where resources are really scarce. As theorized by Paul Connett, the guru of zero waste strategy, there is no waste until that material still contains a drop of usefulness. The core point of the paper is the implementation of a zero waste strategy in a small municipality in Sicily. By building up a SD model we can figure out how saving process connected to the decrease of amount of waste piled up in the landfoll, has been boosting this virtuous cycle, which is bound to cope with the citizens claims about environmental care and lower tax burden level.
Costs of Using Hybrid Cloud Infrastructure: Towards a General Framework
2012
Cloud computing infrastructure is a state-of-the-art computing as a utility paradigm, offering individuals and organizations instantly-available and scalable computing capacity. Organizations may deploy the cloud infrastructure in own data centers, as a private cloud, or use the public on-demand cloud infrastructure charged on a pay-per-use basis. The organizations may also adopt a hybrid solution, i.e. use public cloud capacity to complement the resources in the private cloud, e.g. during the periods of rapid growth in the demand. One of the important factors that affect the organizations’ decisions to adopt a hybrid cloud is the total cost of acquiring and managing the infrastructure. In …
Pricing for Reclaimed Water in Valencia, Spain: Externalities and Cost Recovery
2015
The cost of reclaimed water and the tariffs paid by water users illustrate that the principle of cost recovery is not met in the majority of water reuse projects. However, such projects may also generate positive externalities, contributing to improved welfare of the entire society. This chapter describes the case of the Valencia region of Spain, referring to agreements among water stakeholders. It also includes a proposal of pricing for reclaimed water to be implemented in this area as a pilot case in order to develop a framework for costs and financial, institutional, and social arrangements for water reuse projects. A two-part tariff with a combination of a decreasing and increasing rate…
Energy saving in wastewater treatment plants: A plant-generic cooperative decision support system
2017
Abstract In Europe, the analysis of Waste Water Treatment Plants (WWTPs) shows a significant energy efficiency potential (up to 25%). Optimistically, plant managers assess their plant efficiency once or twice per year. Consequently, the time gap between an inefficiency and its detection produces avoidable operational costs. Although the installation of multiple on-line sensors can provide detailed energy information, for a human operator it is unrealistic to analyse the produced data in a satisfactory time-scale. This paper proposes a cooperative tool for energy saving that remotely accesses and evaluates WWTP databases to produce daily energy assessment reports. The novelty of this decisio…
