The importance of investigating both energy and exergy flows for assessing the environmental profile of buildings has long been acknowledged. Nevertheless, although an ample number of standalone case studies have performed energy analyses in the hospitality industry, empirical studies focusing on exergy are scarce. Extending this line of research, the present study aims to exemplify the conduct of exergy analyses alongside energy ones in optimising environmental management intelligence and improving decision making processes in hospitality accommodation. In doing so, hotels located in international tourism destinations, where tourism has a significant economic impact on the respective countries’ Gross Domestic Product (GDP), participated in the study. Energy data from two hotels situated in the Dominican Republic and, from two hotel units located in Greece was collected and analysed in a comparative manner. Findings revealed that energy flows and energy efficiency alone are not sufficient for a comprehensive assessment of hotels’ energy profiles. Thus, it is suggested that corresponding exergy flows and efficiency rates should also be estimated along with the energy ones. This study infers that location and hotel star rating classification do not seem to be key parameters in assessing lodgings’ energy quality profiles, which suggests the need for further research. The practical implications for hotel managers are also discussed.

Electrifying transportation is a promising approach to alleviate climate change issues arising from increased emissions. This study examines a system for the production of hydrogen using renewable energy sources as well as its use in buses. The electricity requirements for the production of hydrogen through the electrolysis of water, are covered by renewable energy sources. Fuel cells are being used to utilize hydrogen to power the bus. Exergy analysis for the system is carried out. Based on a steady-state model of the processes, exergy efficiencies are calculated for all subsystems. The subsystems with the highest proportion of irreversibility are identified and compared. It is shown that PV panel has exergetic efficiency of 12.74%, wind turbine of 45%, electrolysis of 67%, and fuel cells of 40%.

The transportation sector is one of the largest sources of EU’s greenhouse gas emissions. In 2011, transportation represented approximately 25 percent of total EU’s greenhouse gas emissions. Urban mobility accounts for 40% of all CO2 emissions of road transport and up to 70% of other pollutants from transport. As, transportation and mobility play a crucial part both in urban economics and the quality of life, it is of great significance to ensure a low carbon transportation sector, so as to deal with the threat that climate change poses to urban areas. This study examines the factors that affect the production of carbon dioxide (CO2) as well as of air pollutants, in 9 major European cities, aiming to provide a comprehensive overview of the actual knowledge on the atmospheric pollution from public transportation systems. CO2 emissions as well as air pollutants, such as CO, HC, PM, NOx are calculated for the diesel and CNG bus fleets of the European cities under study. Finally the environmental benefits, in terms of CO2 and CO, HC, PM, NOx emissions reductions, from the penetration of different biodiesel blends (from B10 to B100) to the bus fleets are estimated.

Lignite is by far the most used fuel in Greece for the production of electricity as there are large reserves in the country. The high emissions of global warming gases have led to the need for the adaptation of measures and initiatives to reduce emissions in the Greek energy system for the period up to 2030. It is imperative that an environmental policy and measures are implemented to limit CO2 emissions towards the Kyoto targets. The objective of this work is to analyze the environmental impacts associated with the atmospheric emissions and other wastes that are produced during the extraction, transportation, and use of lignite for electricity production in Greece using the methodology of life cycle assessment. The results presented here indicate that the most significant emission's reduction can be made from technology substitution. The introduction of advanced fossil fuel technologies can also lead to improvements in life-cycle GHG emissions. NOx, SO2, and PM emissions from the lignite life cycle, contributing to the respiratory effects impact category (21.1–28.3%), have a bigger impact than the climate change (10–32.7%) and acidification/eutrophication effects (2.17–3.82%). As per Greece's National Renewable Energy Policy the penetration of renewable energy sources in country's energy mix is investigated. © 2016 American Institute of Chemical Engineers Environ Prog, 2016

The transportation sector accounts for approximately one-fifth of global primary energy use and one quarter of all energy related carbon dioxide emissions, with nearly half of those emissions originating from passenger vehicles. In order to reduce significantly the use of fossil fuels in urban mobility, whilst improving air quality and increasing the accessibility and attractiveness of urban areas, it is necessary to increase the use of non-conventionally fuelled vehicles for passenger and freight transport in urban areas. The introduction of electric vehicles (EVs) is a promising option, so as to achieve decarbonisation objectives, energy security, improved urban air quality and to increase energy efficiency. However, there are a number of challenges for the large-scale deployment of EV both on global and European level. These, in particular, are the high cost of the battery, lack of a standardised recharging infrastructure, relatively low range of battery electric vehicles or lack of interesting value proposition for consumers. A few studies have attempted to calculate the costs and benefits of EVs, but none consider the cost and benefits of EVs at a level of detail comparable to what has been performed for other vehicle technologies. This study constructs the Total Cost of Ownership (TCO) of EVs, based on real data from the auto-industry, in order to assess the costs and benefits as well as the potentiality of electro-mobility deployment in urban areas.

Islands present sustainable energy growth challenges due to a number of reasons such as remoteness, limited energy resources, vulnerability to external events and strong dependence on international trade agreements. In particular, the Dodecanese Islands of the Aegean Sea cover their electricity needs mostly on the basis of autonomous conventional stations, consuming significant quantities of imported oil annually. Renewable energy sources (RES) penetration increase addresses the global requirements towards a carbon neutral environment, and wind farms (WFs) are among the most well-known green electricity-production alternatives. The study explores wind power installation potential of the Dodecanese Islands and the storage or interconnection options, based on the national and European legislative framework and the international scientific literature. The major finding is that, due to the high wind potential of the area, the National policy and targets focus on the installation of great RES power at Greek islands. Hence, private interests, who are willing to carry out the electrical interconnection of islands to the mainland, serve the same objective. Both scientific and business proposals overcome the local wind power installation capacity and neglect local specifics and needs.

The increasing rate of energy consumption, the depletion of conventional energy sources and the environmental degradation caused has led to thorough research on Renewable Energy Sources (RES), which have been seen as a sustainable solution to climatic change. However, RES installation has a considerable environmental impact, which should be taken into consideration. The present study deals with the development of an integrated framework so as to evaluate land environmental suitability for RES installation, especially for Wind Farm (WF) siting. The proposed methodology consists of the Analytical Hierarchy Process, the Geographic Information System and Remote Sensing tools. In the first part, a set of constraints, which are based on Greek legislation and international research, identifies the potential sites for wind park installation. In the second part, a variety of criteria are employed to evaluate the area under consideration. To exemplify the utility of the methodology, an application of the proposed framework to the Dodecanese Islands is further illustrated. One of the first findings is that, despite the implemented restrictions, 1/4 of the land remains suitable for WF siting. The necessity of the method used is confirmed through the comparison of results with the already installed wind parks.

An exergoenvironmental analysis is conducted at the component level of a system and identifies (a) the relative contribution of each component to the environmental impact associated with the entire system, and (b) options for reducing the environmental impact associated with the overall system. In an exergoenvironmental analysis a one-dimensional characterization indicator is obtained using a Life Cycle Assessment (LCA). An index (a single number) describes the overall environmental impact associated with system components and exergy carriers. It should be mentioned that the evaluation of environmental impacts would always be subjective to some degree. The paper discusses the effect of the indicator used in an exergoenvironmental analysis on the conclusions obtained from the analysis using a compression refrigeration machine as an example. The results demonstrate that the contribution of the component-related environmental impact can be neglected in the exergoenvironmental evaluation, and that only the environmental impact associated with the exergy destruction should be considered in the analysis. For the case study reported here, the conclusions extracted from the exergoenvironmental evaluation are independent of the employed environmental indicator.

The need to tackle climate change has pushed the cultivation of energy crops for the production of biofuels to the top of the global agenda. While biofuels produced from energy crops are useful for the reduction of greenhouse gases (GHGs), energy crops per se constitute a farming system that contributes to GHG emissions. The agricultural sector, energy crops included, accounted for an estimated emission of 6.1 Pg CO2 equivalents per year in 2005. The main goal of this study is the development of a consistent methodological approach to quantify the environmental impact of first generation energy crops under the conditions of arid isolated island states, by utilising Life Cycle Assessment (LCA). Comprehensive data regarding the cultivation of maize, sweet sorghum, winter wheat, sugar-beets, potato and winter barley in Cyprus are analysed with the aim to quantify their environmental impact. The study was based on primary data retrieved from pilot studies of energy crops conducted by the Agricultural Research Institute (ARI) in Cyprus. The total environmental impact of the examined crop systems for the production of 1 MJ of crop product was calculated using the CML 2001 methodology and the GaBi software. A comparison of the obtained results with the typical GHG emissions reported in the Renewable Energy Directive (RED) and other studies was carried out. The environmental impact of the investigated crop systems is presented by means of six impact categories: global warming potential (GWP 100 years), acidification potential (AP), eutrophication potential (EP), ozone depletion potential (ODP) and abiotic depletion potential (ADP-fossils). Barley, potato, and wheat crop presented the highest impact. Lower GHG emissions were obtained for wheat and maize crop systems compared to the reported emissions in the Renewable Energy Directive (RED).

The increasing concerns regarding the environmental pollution derived from anthropogenic activities, such as the use of fossil fuels for power generation, has driven many interested parties to seek different alternatives, e.g. use of renewable energy sources, use of “cleaner” fuels and use of more effective technologies, in order to minimize and control the quantity of emissions that are produced during the life cycle of conventional energy sources. The work presented in this paper focuses on the examination of the possibilities of integrating the environmental aspects in the preliminary phase of the conventional design and planning of energy systems in conjunction with other parameters, such as financial cost, availability, capacity, location, etc. The integration of the environmental parameter to the design is carried out within a context where Eco-design concepts are applied. Due to the multi-parameter nature of the design procedure, the tools that are used are Life Cycle Analysis and Multi-criteria Analysis. The proposed optimization model examines and identifiesoptimum available options of the use of different energy sources and technologies for the production of electricity and/or heat by minimizing both the financial cost and the environmental impacts, with regard to a multiple objective optimization subject to a set of specific constraints. Implementation of the proposed model in the form of a case study for the island of Rhodes in Greece revealed that an optimized solution both cost and environmental-wise, would be an almost balanced participation of renewables and non-renewable energy sources in the energy mix

Nowadays, the intensive use of natural resources in order to satisfy the increasing energy demand suggests a threat to the implementation of the principles of sustainable development. The present study attempts to approach thermodynamically the depletion of natural resources in the methodological framework and the principles of life cycle assessment (LCA). An environmental decision support tool is studied, the exergetic life cycle assessment (ELCA). It arises from the convergence of the LCA and exergy analysis (EA) methodologies and attempts to identify the exergetic parameters that are related to the life cycle of the examined system or process. The ELCA methodology, beside the fact that it locates the system parts which involve greater exergy losses, examines the depletion of natural resources (biotic and abiotic) and the sustainable prospective of the examined system or process, under the scope of exergy. In order to obtain concrete results, the ELCA methodology is applied to a large-scale, grid-connected, photovoltaic (PV) system with energy storage that is designed to entirely electrify the Greek island of Nisyros. Four discerned cases were studied that reflect the present state and the future development of the PV technology. The exergy flows and balance for the life cycle of the PV system, as they were formed in the ELCA study, showed that the incoming exergy (solar radiation, energy sources, and materials) is not efficiently utilized. The greater exergy losses appear at the stage of the operation of the PV installation. Due to the fact that contribution of the renewable exergy (solar radiation) to the formation of the total incoming exergy of Life Cycle is significant, it emerges that satisfaction of electric power needs with a PV system appears to be exergetic sustainable. The increase of the Life Cycle exergetic efficiency supported by the future technological scenario in contrast to present scenarios emerges from the increased electricity output of the PV system. Consequently, the increased exergetic efficiency involves decreased irreversibility (exergy losses) of the PV system’s life cycle. The application of ELCA in electricity production technologies exceeds the proven sustainable prospective of the PV systems; however, it aims to show the essence of the application of ELCA methodology in the environmental decision making process. ELCA can be a useful tool for the support and formation of the environmental decision making that can illustrate in terms of exergetic sustainability the examined energy system or process.

Greenhouse gases (GHGs) emitted by road transport vehicles as a direct result of fossil fuel combustion and other environmental pollutants released throughout the life cycle of petroleum based fuels, encourage a shift towards alternative transport fuels. Within this frame, an environmental assessment was performed so as to evaluate the environmental implications of alternative fuels (natural gas and biofuels) penetration in the city buses of the city of Athens. The results are evaluated in terms of CO2, CO, HC, PM and NOx emissions. The findings show that CO2 emissions are significantly reduced in CNG buses compared to diesel powered buses. CO2 emissions can also be reduced by 7.85% in B10 blends and 78.45% in B100 blends, compared to diesel. The environmental assessment can be considered as a basis so as to investigate the viability of replacement of petroleum- based diesel with natural gas and biofuels in city transport buses. Concepts for sustainable bus transportation can be incorporated using the methodology defined in this study, in order to promote a sustainable transportation system and mitigate the climate change.

In the current paper, the wind potential of a relatively flat area in central Peloponnese in Greece has been studied. The chosen region was selected based on environmental criteria and the wind speed was correlated based on the measurements of three specific mountainous sites in the wider plateau area using a Wind Resource Analysis (WRA) modeling methodology. Digital elevation data sets were used for the modeling procedure together with the Wind Atlas Analysis Program for the correlation process and the basic aim was to evaluate and identify appropriate sites for wind farm development within the flat area and compare the estimated net power output with the net power output from mountainous sites in the wider central Peloponnese area. Dust dispersion mapping from mining operations in the area contributed also to defining the physical boundaries for wind farm development.

The environmental and energy parameters of Photovoltaic (PV) systems play a very important role when compared to conventional power systems. In the present paper, a typical PV-system is analyzed to its elements and an assessment of the material and energy requirements during the production procedures is attempted. A Life Cycle Analysis (LCA) is being performed on the production system of photovoltaics. Energy and environmental analyses are extended to the production of the primary energy carriers. This allows having a complete picture of the life cycle of all the PV-components described in the present study. Four different scenarios are examined in detail providing every possible aspect of scientific interest involving polycrystalline PV systems. In order to obtain concrete results from this study, the specific working tool used is the Eco-Indicator ’95 (1999) as being reliable and widely applied and accepted within LCA community. A process that relates inventory information with relevant concerns about natural resource usage and potential effects of environmental loadings is attempted. Large-scale PV-systems have many advantages in comparison with a conventional power system (e.g. diesel power station) in electricity production. As a matter of fact, PV-systems become part of the environment and the ecosystems from the moment of their installation. Carbon Footprints of various PV-systems scenarios are greatly smaller than that of a diesel power station operation. Further technological improvements in PV module production and in the manufacture of Balance-of-System components, as well as extended use of renewable energy resources as primary energy resources could make Carbon Footprint of PV-systems even smaller. Extended operational period of time (O.P.T.) of PV-systems determined by system reliability should be given special attention, because it can dramatically mitigate energy resources and raw materials exploitation
