Hybrid Energy Systems

The energy demand within the world has improved for a few reasons because of technical advancements, increasing enterprises, and increasing commercial energy consumption. Sufficient energy models will support the accurate use of renewable resources like solar, wind, biomass, biogas, and the fuel cell is a portion of the advantages used. Hybrid energy systems of these advantages will contribute viably to sustainable development and electrification in rural areas that do not access power grids. This study reviews the performance analysis of hybrid system along with conventional resources for sustainable development in remote areas. This paper also reviews the recent trends in energy usage from available renewable energy sources in addition to examine an expansive review of the performance analysis of different hybrid energy technologies in rural areas. It is also discussed the relative investigation of hybrid energy systems along with conventional energy sources particularly suited to the small and isolated areas supported by the literature. In continuation of this, the paper also discusses the future energy sources.

Prefabricated Building

In the era of sustainability as the development concept, prefabricated buildings have gradually become an important way to achieve sustainable development of the construction process due to the advantages of high construction speed, energy-saving, and environmental protection. In order to make the prefabricated building develop in a sustainable direction, it is necessary to understand the importance and performance of the critical sustainability aspects of the prefabricated building. However, the existing research has not fully explored this point, and classification research on all aspects of sustainability according to the management priorities of sustainable development is lacking. The present study determines the critical sustainability characterization items (criteria) of prefabricated buildings and uses the importance-performance analysis (IPA) method to explore the sustainability importance and performance level of prefabricated buildings in Guangzhou on the basis of the three dimensions of economic, social, and ecological sustainability. In particular, this study revises the traditional IPA method and uses the comprehensive weight obtained by the analytical network process- (ANP-) entropy weight method to obtain the importance of items. Results show that items “environmental protection” and “construction civilization” are of high importance and perform well. “Construction cost” and “product quality” are considered high-importance items with relatively poor performance; that is, these areas require urgent improvement actions. The “policy support” item at the intersection of IPA coordinates is also an aspect worthy of attention and discussion. This study provides a useful reference for decision-makers and relevant personnel on determining the priority of project management and achieving the optimal allocation of resources to promote the sustainable development of prefabricated buildings.

Abstract Continuously improving freshwater aquaculture efficiency will help promote the sustainable development of freshwater aquaculture, which is crucial to ensure fish food supply. In particular, finding ways to improve the freshwater aquaculture efficiency, by measuring and analyzing the total factor productivity (TFP) of freshwater aquaculture, is of great significance to the sustainable development of freshwater aquaculture industry. Therefore, this paper constructs a meta-frontier Malmquist index (MMI) model by considering the regional heterogeneity to evaluate the TFP of freshwater aquaculture of China from 2004 to 2019. The results show that: (1) From 2004 to 2019, the TFP of freshwater aquaculture shows dynamic fluctuations and spatial differences. Compared with coastal regions, there are obvious advantages in TFP of freshwater aquaculture in inland regions. (2) The change of TFP in freshwater aquaculture is driven by the combined effect of technology change (TC) and technical efficiency change (EC). (3) The technology gap in freshwater aquaculture of coastal regions is tiny, while that of inland regions is large. This paper finally gives some policy suggestions to improve the TFP to ensure the sustainable development of freshwater aquaculture.

Energy Intensive Industries

Egypt’s heavy reliance on energy- and capital-intensive industries currently hinders its drive towards achieving sustainable development goals. This paper studies environmental total factor productivity (ETFP) for ten energy-intensive industries using the Malmquist index and data envelopment analysis (DEA) for the period 2002-2014. Through incorporating CO2 emissions by energy intensive industries, DEA helps identify both environmentally-efficient and inefficient industries. Findings indicate that: i) ETFP has remained almost unchanged for the 10 industries, with ‘technical progress’ improvement almost fully outweighed by an efficiency deterioration, ii) excluding the environmental component indeed yields overestimated total factor productivity (TFP). In its estimation of ETFP, the paper adds to exiting empirical literature since no similar estimation has been done for Egypt. Results may be relevant to other countries with similar industrial structures. Policy implications include the reliance on renewable sources of energy, bearing directly on the achievement of the seventh, ninth and twelfth SDG goals. Keywords: environmental total factor productivity; energy intensive industries; data envelopment analysis; Egypt
