Local Green Power Supply Plants Based on Alcohol Regenerative Gas Turbines: Economic and Environmental Aspects
2020
Growing economies need green and renewable energy. Their financial development can reduce energy consumption (through energy-efficient technologies) and replace fossil fuels with renewable ones. Gas turbine engines are widely used in transport and industry. To improve their economic attractiveness and to reduce harmful emissions, including greenhouse gases, alternative fuels and waste heat recovery technologies can be used. A promising direction is the use of alcohol and thermo-chemical recuperation. The purpose of this study is to estimate the economic efficiency and carbon dioxide emissions of an alcohol-fueled regenerative gas turbine engine with thermo-chemical recuperation. The carbon …
Renewable energies: Worldwide trends in research, funding and international collaboration
2019
The main aim of this study was to analyse scientific and energy production, funding, collaboration among countries and most cited papers on the renewable energies topic through bibliometric and social network study of articles included in the Web of Science database. 12,167 papers were recovered from 2007 to 2016. Wind power is the energy from which a greater number of articles have been published (n = 3,930), followed by solar energy (n = 2,570) and ocean energy (n = 1,565). The United States leads the world production of articles (n = 2,320), followed by China (n = 1,629), the United Kingdom (n = 1007), Germany (n = 730) and Spain (n = 729). China is the leading country in financed works …
European Union commitment towards RES market penetration: From the first legislative acts to the publication of the recent guidelines on State aid 20…
2015
Abstract During the last three decades, the European Union (EU) commitment towards the Renewable Energy Sources (RES) market penetration has been very complex, involving several aspects pertaining to the economic and political action of Member States. This paper seeks to overview the historical development of the legislative EU framework, including a description of the main financial programmes established and managed by the EU Directorates General. Moreover, the work will proceed with the picture of some Investment Funds, ad hoc created for RES undertakings, and managed by the European Investment Bank (EIB) in collaboration with the EU or other foreign Bank Institutes. The delicate matter …
The socioeconomic impacts of local energy programmes: a case study of Avrig, Romania
2014
Purpose – The purpose of this paper is to investigate the expected economic and social effects of the “Local Energy Plan” – a programme of the local administration that aims to transform the Romanian town Avrig until 2020 into an energy independent town relying exclusively on renewable energy resources. Design/methodology/approach – The study uses a mixed-method approach to investigate the effects of a small town's transition to renewable energy. This approach consists of a series of in-depth interviews with the local authorities, investors, other representatives of the business sector and citizens of Avrig and economic modelling to determine the direct effects generated by the implementat…
Cost analysis of the facilities deterioration in wastewater treatment plants: A dynamic approach
2019
Abstract The implementation of the Directive 91/271 / CEE resulted in the proliferation of new Wastewater Treatment Plants (WWTPs) all around Europe. These facilities, which are compound by a wide range of assets (civil works, electromechanical equipment, pipelines, etc.), are ageing and deteriorating having an impact on the efficiency of the process. It is founded that repairs and corrective maintenance costs have increased in the last years, due to the deterioration process. Therefore, the aim of the present study is to focus on the cost effects of the deterioration process of the facilities in different wastewater treatment technologies. The analysis of these impacts will allow the opera…
The Spanish Turn against Renewable Energy Development
2018
[EN] In this study, we focus on the case of Spanish energy policy and its implications for sustainable energy development. In recent years, Spanish legislation has changed dramatically in its approach to sustainable energy sources. This change is despite EU and international efforts to increase energy efficiency, and to accelerate the transition to renewable energy sources (RES) in order to reduce greenhouse gas emissions. Based on the socio-technical transitions literature, this paper assesses the role of the new legislation in this altered scenario, and analyzes the evolution of energy production in Spain in the EU context. The results are triangulated with two expert assessments. We find…
Unwanted effects of European Union environmental policy to promote a post-carbon industry. The case of energy in the European ceramic tile sector
2016
Global warming combined with low carbon transition plans is threatening the future of high energy consumption industry sectors in the European Union (EU). The need to respond to environmental challenges is demonstrated by support for international level energy policies and legal requirements, such as the Kyoto Protocol which the EU supports, and increased EU-level environmental legislation and energy policies. The effect of these initiatives is gradually transforming industrial activities in the EU. However, since not all countries have adopted these policies, evaluation of their net effect needs to take account also of side-effects such as delocalization of industry activity and the legal …
Non-family employees in small family business succession: the case of psychological ownership
2013
This study is analysing non-family employees' perceptions on psychological ownership during the family business succession process. Three small family companies were chosen for the multiple case studies. The results of this study show that non-family employees are participating on the small family business succession and they do possess a strong psychological ownership towards the family business, their own work, and the founder generation. Non-family employees recognise the changing management and leadership in successions. Non-family employees' psychological ownership increases in succession. This has got influence on commitment and well being in unique way according to personal character…
Stakeholder perceptions of alternative food entrepreneurs
2009
This paper focuses on rural entrepreneurs' perceptions of their stakeholders with respect to their influence towards the economic success of farms and environmental issues, as well as their trustworthiness. There is special emphasis on the comparison of perceptions between suppliers of alternative food supply chains and suppliers of conventional supply chains. Survey research, with a final sample size of 522 rural entrepreneurs in Central Finland, was used as a research method. The results showed that 28% of the respondents could be defined as alternative food entrepreneurs. Significant differences between alternative and conventional food entrepreneurs were related to perceptions towards c…
The Go2School project for promoting cycling to school: A case study in Palermo
2021
Abstract The identification of transport policy measures able to reduce the use of private cars for home-to-school travel is very relevant to reduce congestion during peak hours and to ensure that the areas around schools have livable environments. An action that policymakers could apply is promoting cycling to school through the introduction of bikesharing programs and creating safe routes to school through the construction of new cycle infrastructure. The aim of the paper has been, therefore, to assess if these policies could lead the high-school students to cycle to school, considering the city of Palermo as a case study. The goal is reached through the calibration of a modal choice mode…
