The purpose of this paper is to analyze wind climate parameters and performance functions, on the basis of two years of data, and reliability of Pakistan’s first wind farm located at Jhimpir, Sindh.

The methodology covers assessment of wind climate parameters including wind variation at different hub heights, wind shear and diurnal wind shear. In addition, a performance assessment of a wind farm on the basis of technical and real availability, capacity factor and failure rate of mechanical and electrical components has been conducted. The Weibull method has been used for reliability analysis. The maintenance model is proposed for improving the performance. Last is about annual energy volume lost and of financial constraints’ assessment.

The monthly mean wind variation at heights of 80, 60 and 30 m was found to be 8, 6.9 and 5.9 m/s, respectively. The monthly mean wind shear coefficient was found to be 0.2419. The performance assessment of the wind farm includes technical and real availability, and the capacity factor was found to be 97, 90 and 35.5 per cent, respectively. The failure rate found in the first and second year was 8 and 14 per cent, respectively. Reliability decreased from the first year to the second year, i.e. 0.89 to 0.71 per cent. The components’ failure frequency rose to 57.2 per cent in the second year. The lost energy production due to electrical and mechanical failures was 27.241 GWh in two years that cost Pakistani Rs. 329.8m.

The results of the assessment show that a wind farm needs drastic maintenance strategies to maximize the its performance.

Determining the suitable material and accurate thickness of the thermal insulation layer used in exterior walls during the design phase of a building can be challenging. This study aims to determine suitable material and optimum thickness for the insulation layer considering both operational and embodied factors by a comprehensive assessment of the energy, economic and environmental (3E) parameters.

First, the energy model of an existing building was created by using Autodesk Revit software according to the as-built floor layout to evaluate the impact of five alternative insulating materials in varying thickness values. Second, using the results derived from the model, a thorough evaluation was conducted to ascertain the optimal insulation material and thickness through individual analysis of 3E factors, followed by a comprehensive analysis considering the three aforementioned factors simultaneously.

The findings indicated that polyurethane with 13 cm thickness, rockwool with 10 cm thickness and EPS with 20 cm thickness were the best states based on energy consumption, cost and environmental footprint, respectively. After completing the 3E investigation, the 15-cm-thick mineral wool insulation was presented as the ideal state.

This study explores how suitable material and thickness of insulating material can be determined in advance during the design phase of a building, which is a lot more accurate and cost-effective than applying insulating materials by assumed thickness in the construction phase.

To the best of the authors’ knowledge, this paper is unique in investigating the advantages of using thermally insulating materials in the context of a mosque structure, taking into account its distinctive attributes that deviate from those of typical buildings. Furthermore, there has been no prior analysis of the cost and sustainability implications of these materials concerning the characteristics of subtropical monsoon climate.

This paper aims to quantify the potentials for the development of combined heat and power (CHP) in Europe.

To this end, it uses the TIMES-EU energy-economic model and assesses the impact of key policy options and targets in the area of CO₂ emissions reduction, renewable energies and energy efficiency improvements. The results are also compared with the cogeneration potentials as reported by the Member States in their national reports.

The paper shows that CHP output could be more than doubled and that important CHP penetration potential exists in expanding the European district heating systems. This result is even more pronounced with the far-reaching CO₂ emissions reduction necessary in order to meet a long-term 2 degree target. Nevertheless, the paper also shows that strong CO₂ emission reductions in the energy sector might limit the CHP potential due to increased competition for biomass with the transport sector.

Given the proven socio-economic benefits of using CHP, the paper identifies the areas for future research in order to better exploit the potential of this technology such as the combination of CHP and district cooling or country- and industry-specific options to generate process heat.

This paper aims to discuss the urgent need to develop a sound and robust universal framework that would prove helpful in creating uniform acceptability of Islamic financial instruments. Among many problems, a particular problem in developing a uniform global framework for Islamic financial instruments is the existence of different madhahib within Islamic Fiqh. The leading and the most prominent Sunni madhahib that have survived till today are four, the Hanbali, Shafi, Maliki and Hanafi, while the most prominent Shia madhab is the Jafari madhab.

The research approach was descriptive and exploratory in nature. Secondary resources were used except for a semi-structured interview with a Shariah scholar with the justification that his knowledge and experience regarding the subject matter may prove helpful. The methodology included a systematic review of already issued Sukuk by various madhahib. Compared to a simple narrative review of a few case studies regarding Sukuk, this methodology has a benefit to provide the reader the power to assess the review and even replicate it. The results of this systematic review are summarized in the form of tables.

Ingredients were determined that would help make a truly global Sukuk security, a model acceptable to all madhahib of Islamic Fiqh. These ingredients include rentals, relationship between special purpose vehicle (SPV) and originator, transference to SPV, Sukuk structure, guarantee, liquidity, listing and tradability, convertibility, subordination and post-Ijarah price. Moreover, specific steps were also analyzed that must be taken to issue such type of Sukuk al-Ijarah.

This study is focused only on a type of Islamic financial instrument, i.e. Sukuk whose underlying was Ijarah-based contracts. This is due to lesser global acceptability for other Islamic financial instruments including other forms of Sukuk. Based on the nature of study, purposive/judgmental sampling was done. The sample population was 40 Sukuk (nine each from Hanafi, Shafi and Maliki madhahib, five each from Hanbali and Jafari madhahib and three from non-Muslim zones). Some Sukuk were dropped due to non-availability of enough data and to keep some semblance between the impact of the madhab on financial world and the data.

For practitioners and regulators, on the basis of the given recommendations, it would be possible to create a standardized product, acceptable for all madhahib of Islamic Fiqh. This standardization will lead to a unified platform that can attract a larger investor pool as well as better integration. For practical purposes, the proposed model of Sukuk al-Ijarah can be replicated for other Islamic financial instruments for global acceptability.

For an Islamic society, the expansion of Islamic economic system depends principally on unity. So integration is critical and also essential for the success of any Islamic financial instrument. When the society will move away from Riba and its associated evil, the society will move in a positive direction, while still making profits. The proposed model may also be utilized for socially responsible initiatives like protection of natural resources, advancement of renewable energy, economic development and rehabilitation to name a few.

Previous studies were silent on the development of comprehensive frameworks acceptable to all madhahib of Islamic Fiqh. This research study is the first study of its kind and is the first step toward integration, as it would try to suggest a global framework for Sukuk al-Ijarah that can be acceptable by the followers of any madhab of Islamic Fiqh.

Bioenergy is a key component of climate change mitigation strategies aiming at low stabilization. Its versatility and capacity to generate negative emissions when combined with carbon capture and storage add degrees of freedom to the timing of emission reductions. This paper aims to explore the robustness of a bioenergy-based mitigation strategy by addressing several dimensions of uncertainty on biomass potential, bioenergy use and induced land use change emissions.

Different mitigation scenarios were explored by two different energy-economy optimization models coupled to the same land use model, which provides a common basis for the second generation bioenergy dynamics in the two energy-economy models.

Using bioenergy is found to be a robust mitigation strategy as demonstrated by high biomass shares in primary energy demand in both models and in all mitigation scenarios.

A variety of possible storylines about future uses of biomass exist. The comparison of the technology choices preferred by the applied models helps understand how future emission reductions can be achieved under alternative storylines.

The presented comparison-based assessment goes beyond other comparison studies because both energy-economy models are coupled to the same land use model.

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

The purpose of this paper is to evaluate the soybean agricultural production system and the subsequent industrialization processes in order to assess the environmental sustainability of the soybean chain in Brazil and, also, to evaluate the amount emergy exchanged in the soybean trade.

The emergy accounting methodology was used as analysis tool in this paper.

The main findings were, first, the distribution of emergy flows inputs according to soybean chain stages, being 94 percent used by the agricultural production system, 1 percent used by transport to industry, 4 percent used by crushing, and 1 percent for oil refining. Second, emergy indicators showed negative sustainability trends trough the soybean chain stages. Third, the emergy exchange ratio demonstrated that the soybean farmers are delivering around five times more emergy with the soybean sold that the emergy they are receiving with the money paid for it and, thereby, depleting its local natural resources.

The agricultural production stage uses the highest amount of resources. Therefore, any improvement in the management of this stage will result in improvement of the whole soybean chain. In this context, the adoption of more sustainable soybean agricultural production systems becomes fundamental for the long‐term environmental sustainability of the soybean chain. Organic production models and agro‐forestry technologies should be used toward more sustainable soybean chain because it can help to decrease the dependence of the soybean production systems on external non renewable resources.

Emergy accounting methodology provides a very comprehensive tool to complement and complete energy, economic and social information about the soybean chain in Brazil. The emergy exchange ratio provides information to access and enrich the discussion about soybean fair trade.

The neighborhoods north and northwest of downtown St Louis are blighted by their abundance of substandard, abandoned, and demolished housing. Crime, poverty, and unemployment are high while family stability, educational achievement, and health outcomes are low. These conditions are not unique to St Louis, but can be found in neighborhoods in every city in America. How did this happen? What factors led to the demise of these neighborhoods? This chapter examines the history of St Louis along with theories of neighborhood succession to identify possible explanations for the city's collapse.

This paper aims to explore the functionality of long tail markets (LTM), where the consumers cannot be reached or are ignored by the traditional mainstream businesses, in new products and business development.

First, the authors review two Chinese entrepreneurial practices in the Fintech sector and low-speed electric vehicles (LSEV) and describe their stylized facts; second, they explore a possible theoretical LTM framework to underscore these practices; third, they make a connection between LTM and existing business models and analyze its significance and practical implications in business, in particular, in developing economies.

The LTM business approach has helped Chinese companies in the Fintech sector and LSEVs gain global attention. The success factors of LTM for businesses are identifying a specific customer base, being aware of localization products and playing skillfully with regulations; the LTM approach has several overlaps with existing studies on niche products and base of the pyramid market.

Based on some emerging and attractive business practices in China, this paper offers a valuable attempt to theorize them as long tail phenomenon. The LTM thesis provides a potential framework to reference for similar methods elsewhere and may illuminate entrepreneurship to be explored in similar markets.

The main objective of this paper is to analyze works of literature on SRI sukuk to highlight the potential for these kinds of instruments in financing more sustainable financial systems (SFSs). The analysis mainly accentuates a dearth of knowledge on the various challenges and opportunities in the realm of SRI.

This paper pioneers the bibliometric and systematic literature review of the development of the SRI sukuk from 2016 (the first available year in the field) to and 2021.

The study findings highlighted several pertinent SRI issues: the lack of standardization due to the different interpretations of Shariah and green, the lack of retail investors, which inevitably produce a lack of liquidity in the secondary market, thus limiting their growth, its funding allocation’ close resemblance to green financing, and the role of Malaysia and Indonesia as global sustainable financial hubs to stimulate the development of Shariah-compliant sustainable instruments and contribute to the international debate about the building of a global standardized framework related to sustainable investments.

The integration of the environmental principles of a green bond with the Shariah-compliant financial structure of a sukuk, the SRI sukuk, represents a vital crossroad in both sustainable and Islamic finance. Social-impact sukuk and green sukuk is an undervalued instrument that could play an important role in financing a more sustainable economic and financial system, including Islamic investing. This kind of instruments, which is based on a “pay for success” principle in the conventional layout, perfectly fit with the profit-and-lost sharing’s (PLS's) ethicality, the sustainability principles of Islamic finance and the religious principles of Islamic law.
