“…Numerous recent reviews on sustainable energy, efficient energy management and modelling for energy demand have been published and these articles are generally restricted to concentrate on dissipated infomation of scattered data on renewable energy and environmental sustainability (Islam, Taufiq‐Yap et al, 2013a; Islam et al, 2015; Kabir & Khan, 2020; Masud et al, 2019; Nazir et al, 2019, Uddin et al, 2019b, 2019a). Some studies presented the technological innovations on energy intensity (Amin & Rahman, 2019c, Chowdhury et al, 2020; Masud, Nuruzzaman, Ahamed, Ananno, & Tomal, 2020; Pan, Uddin, Han, & Pan, 2019), efficient energy management practices (Alam, Alam, Chowdhury, Sarkar, & Paul, 2019; Hasan, Hossain, Tuhin, Sakib, & Thollander, 2019) and foreign investment in Bangladeshʼs power sector (Islam, Chan et al, 2014a; Islam, Teo, Awual, & Taufiq‐Yap, 2019). Very few studies have attempted to review critically associated with fuel diversification in the future energy system of Bangladesh.…”

Despite the numerous exemplary efforts taking place to develop sustainable systems of power generation globally, coal will remain an essential and significant part of Bangladeshʼs energy generation. The Government of Bangladesh needs to provide a more reliable and transparent power market for citizens to meet Bangladeshʼs rising energy demand. Consequently, various coal‐based mega projects were undertaken by the Bangladesh government to ensure an affordable and reliable power supply. Half of the targeted electricity was designated to be produced from imported coal. Hence, the development strategy or the reformation of policy in the energy sector may contribute to the current shortcomings in policy approach including inadequate energy infrastructure, regulation and co‐ordination issues. This review focuses on the increasing demand for coal, supply issues, socio‐environmental requirements and significant coal import to encourage realistic advancement of the energy sector in Bangladesh. Moreover, forecasting the requirement of coal for mega power projects from 2021 to 2041 was highlighted. The water resource supply for coal‐based power plants and approaches for reducing CO2 and other emissions were also addressed. Finally, initiatives for fulfilling Sustainable Development Goals in the Bangladesh energy sector were also discussed in this review.

“…It revealed the 1900-1998 energy (exergy) efficiency curve for the USA, where the 25-year curve, in general, tends to form a straight line. Assumption strengthened after studying research results, among others (Badmus and Osunleke, 2010;Chowdhury et al, 2019;Chowdhury et al, 2020;Kondo, 2009;Mitra and Gautam, 2014), regarding other efficiencies. The estimation results using formula ( 23) are then compared with the results of historical efficiency improvements on average: 1 [%/year] (Gilli et al, 1995…”

Quantification of global sustainable energy security (ES) becomes urgent, but the concepts of ES are still not clear. Thus, this paper is originated from philosophical ES studies, in which the various concepts came from the differences in determining the observed multi-matters (energy, equipment, human, and ecosystem: EPME) and point of view to see the EPME. Therefore, this research is aimed at measuring the EPME variables, producing ES material quantities (Q es ). Q es is derived after a 4-stage unification and is defined in a formula. The formula is then applied to calculate the top ten populous nations in the world from 1990 to 2015. Based on the top Q es values, the rankings are Russia (Fed.), USA,

“…Sustainability assessment plays an important role in energy systems. The sustainability assessment tools on energy systems are beneficial at justifying an energy policy by discussing the effects of different sources of energy, determining the impact of waste energy and exergy on the environment, suggesting measures to reduce emissions, and encouraging the application of more environmentally benign solutions (Chowdhury et al 2020a). A sustainable system refers to a system that does not cause permanent damage to the environment and does not consume excessive resources while performing an efficient operation for a long enough service period and leaving a clean environment and enough resources to posterity to meet their needs of natural resources (Dincer and Zamfirescu, 2018).…”

This paper introduces the basics of exergy-based sustainability assessment and the framework that should be shaped within the first stage. The sustainability assessment framework leads to sustainability indicators that are used to assist policymakers and decision-making processes. The literature review shows that the energy systems are suited to sustainability assessment with exergy based assessment tools and indicators from an environmental point of view. In this study, an exergy based sustainability assessment is carried out by using the exergy analyses results of an ORC (organic Rankine cycle) integrated waste heat recovery system on a 1,221 TEU container ship. The exergy analysis results are used to derive comparable and quantified exergetic sustainability indicators that indicate the sustainability level and further improvement potentials with the utilization of the proposed waste heat recovery system design. The assessment results show that the minimum waste exergy ratio is obtained with the value of 0.106 when R1234ze(Z) is used and the evaporating pressure is 3 MPa. R1234ze(Z) and R245fa working fluids show good environmental performance for the proposed system design. The maximum exergetic sustainability index value is obtained with the value of 8.435 when R1234ze(Z) is used and the evaporating pressure is 3 MPa.
