“…Exergy is the amount of work obtainable when a matter is brought to a state of thermodynamic equilibrium with the uniform environment reference (Szargut, 1980;Rosen and Dincer, 1997;Dincer, 2002;Rosen, 2009b), and it is an effective measure of the potential the matter impacts or changes the environment (Dincer and Rosen, 1998;Utlu and Hepbasli, 2004;Dincer, 2007;Koroneos and Tsarouhis, 2012). Therefore, some researchers suggested that the environmental impacts of emissions are best addressed by considering exergy (Rosen and Dincer, 1997;Dincer, 2000;Midilli and Dincer, 2010;Caliskan, 2015).…”

“…Rosen (2017b) furthered to state that sustainable development is a multidisciplinary concept involving environment, ecology, sociology, economy, science, and engineering. Generally, sustainable development involves economic sustainability, social sustainability, and environmental sustainability, and all of them link to energy and resources sustainability, since all of these are strongly interlinked (Dincer and Rosen, 2005;Romero and Linares, 2014) and energy/resource sustainability is of great importance to the overall sustainability (Rosen, 2009b). Energy/resource sustainability is therefore focused on in the following sections.…”

“…The world production of fossil fuels nearly increased monotonically in the range of 9.76-11.39 ×10 3 Mtoe with an increase rate of 16.70%.

“…Generally, sustainability encompasses several perspectives or pillars. Most of the scholars prefer that sustainability is a triangle of economic sustainability, environmental sustainability, and social sustainability which is shown in Figure 1 (Rosen, 2009b;Romero and Linares, 2014;Bilgen and Sarıkaya, 2015;Rosen, 2017 a). Dincer and Rosen (2005) furthered to state that sustainable development involves four key factors: environmental sustainability, economic sustainability, social sustainability, and resource/energy sustainability (Figure 2).…”

At the same time of providing a huge amount of energy to the world population (social sustainability) and global economy (economic sustainability), the fuel itself also releases a great amount of emissions to the environment the world people live in in the forms of gaseous pollutants (SOx, NOx, CO, CO2, CH4, etc.) and ash compositions (Al2O3, CaO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SO3, SiO2, TiO2, etc.), seriously impacting the environment (environmental sustainability) for the world population and global economy. Sustainability generally encompasses economic sustainability, environmental sustainability, and social sustainability, and all of these are significantly related to the energy/resource sustainability. This study addresses the sustainability of fuel from the viewpoint of exergy. It is demonstrated that the energy of a fuel is best evaluated by its chemical exergy, and the environmental impact of a fuel can be assessed through the chemical exergy of its emissions (the specific impacts such as toxicity or greenhouse effect are not detailed). Then, the sustainability of fuel can be understood from the viewpoint of exergy through three ways: (a) high chemical exergy of the fuel, (b) high exergy efficiency of the fuel conversion process, and (c) low chemical exergy of the emissions.

“…The economic sustainability of rural electrification solutions requires ensuring the funding or affordability of the systems (i.e. the initial investments and the operation and maintenance (O and M)) (see, e.g., [23,[38][39][40]). In this context, it is important to provide a cost-effective solution for electrification [23,38].…”

Are the Rural Electrification Efforts in the Ecuadorian Amazon Sustainable?

Abstract:In this paper, we assess the sustainability of rural electrification programs in Ecuador, paying special attention to programs targeting small indigenous communities in the Amazon basin. Our assessment considers four dimensions of sustainability (institutional, economic, environmental, and socio-cultural) and is based on an exhaustive qualitative document analysis, complemented by semi-structured expert interviews. We found that disruptive changes have affected the electrification policies in Ecuador during decades of avoiding the development of strengthened institutions. Despite this major drawback, we found that there is a consensus on granting access to energy for all. This partially explains the national efforts, persistent through different administrations to fund rural electrification. However, in the case of off-grid photovoltaic solutions, these efforts have consistently neglected allocating funds for operation and maintenance, which has seriously compromised the sustainability. Moreover, although Ecuadorian officials declared to favor stand-alone photovoltaic systems in the case of indigenous communities in the Amazon, we found that environmental or socio-cultural aspects have a minor role in the selection of these systems. Progress regarding environmental awareness, social acceptance, and cultural justice, is still needed for ensuring the sustainability of rural electrification efforts in the Ecuadorian Amazon.

Thermal energy is one of the most widely encountered energy forms in our daily life. To ensure efficient utilization and conversion of this energy, the balance between supply and demand needs to be maintained. For this purpose, thermal energy storage is required. There are various thermal energy storage systems available; one of the most basic is sensible thermal energy storage which includes rock thermal energy storage (RTES). This rock‐based energy storage has recently gained significant attention due to its capability to hold large amounts of thermal energy, relatively simple storage mechanism and low cost of storage medium. Accordingly, numerous studies have been conducted to elucidate the basic flow and heat transfer mechanism and to evaluate the performance of this energy storage. The major technical challenges hindering the wide adoption of this technology are the enormous pressure drop across the storage and nonoptimal heat transfer from the heat transfer fluid to the storage medium and vice versa. These issues will directly and indirectly affect the overall cost (capital, operational, and maintenance costs) of the system. To eliminate this issue and assist further development of this technology, it is crucial to compile and extract important findings from these previous studies, identify the challenge and research gap, and draw guidelines for the upcoming research and development. At the moment, this kind of compilation does not exist. Hence, this paper is prepared with the primary objective to comprehensively review the current technology and development of RTES and to propose a potential way forward based on the pain point identified. Discussion on the nontechnical aspect such as policy and regulations as well as community awareness will also be outlined and discussed.
