Managing Supply Chain Activities in the Field of Energy Production Focusing on Renewables

: Nowadays, the research community focuses on sustainability studies that are at the severe phase in the transformation towards a sustainable world. In addition, reducing the human impact on the environment requires a shift from traditional energy to renewables, which have increased signiﬁ-cantly during recent decades as sustainable energy sources. Hence, this study assesses renewable energy sources and their related production phases from a supply chain management perception, screening and reviewing the integration between the supply chain management within the area of energy production focusing on renewable energy resources. The study executes a systematic review of English literature published on international scientiﬁc databases, focusing on the previous decade 2010–2020, to congregate the recently updated knowledge related to such research area. Thus, this study provides an authentic review of the literature that points to the relationship between supply chain operations and the area of renewable energy manufacturing from another side. Several literature reviews have been available concentrating on particular areas of managing renewable energy supply chains; however, no review has highlighted the practices of supply chain processes in energy production, focusing on renewables. The searching process relies on the published works that focus on such an area to be analyzed and characterized based on different methodologies they propose; thus, prospective and future research interests are delineated.


Introduction
Renewable Energy (RE) has been a vital concern in the clean economy by decreasing the usage of polluted energy (e.g., fossil energy) because of its greenhouse gas (GHG) emissions [1][2][3][4][5][6][7].RE sources such as solar, wind, and tidal power are environmentally friendly by nature [2,[7][8][9][10] and cheaper energy production [11,12].Therefore, RE sources are evolving options to fulfill the energy future demand [8,13] because they are renewed with a continuous cycle [14].RE as reasonable resources has grown extensively in the last 30 years [15], as governments and worldwide companies extensively unrestricted their goals to boost the development of RE production [16].For example, a cooperative work has been prepared to discover several methods in which wind energy will offer 20% of U.S. electrical power by 2030; wind power projects conducted in China aim to transfer 15% of its total energy consumption in 2020 by operating 24 offshore wind projects with a capacity of 6.7 GW [17,18]; and leading IT companies, such as Apple, Google, and Facebook are pushing noteworthy plans to run their organizations with a growing percentage of RE resources [11].
P. Venturi, et al. (1999) [19] was the first published work representing the relation between the Supply Chain (SC) and RE production unintentionally, as the paper analyzed the production chains of woody energy crops.From that time, the importance of Supply Chain Management (SCM) in the RE sector has attracted the attention of the public, private actors, and academic communities, with the knowledge that an effective SC for the RE deployment can extensively support power sector expansion [20].Nonetheless, the SC systems for the RE deployment are still challenging with regard to the capital investment, energy conversion costs, logistics networks, geographical constraints, and lack of economies of scale [9,21].Besides, with reference to the growth of environmental responsiveness in terms of the supply chain concepts, new trends initiated in the literature explicitly include the Green Supply Chain (GSC), the Sustainable Supply Chain (SSC), and the circular supply chain [22][23][24].Concepts such as the SSC and the sustainability implications of the GSC have an influential role in the RE sector, offering weighty sustenance for the expansion of the power sector and making it easy for organizations to simply approve these practices [25,26].However, the challenges of energy SCM show a discrepancy in the literature concerning energy production technologies, especially renewables.
Therefore, the SCM of energy sectors and their infrastructures clarifies energy resources' availability and their costs, which might blaze a trail for further saleability of RE resources [27,28].Nevertheless, higher conversion costs, limited sites, environmental influences, etc., pose obstacles to such development [9].Therefore, the significant expansion of renewable energies has challenges from a SCM side; also, the integration between RE and the SC has a fundamental part in the economic and social improvements [29], so the relation between them is one of the imperative research topics.As a result, the literature on logistics and supply chain practices in the renewable energy context has been amalgamated with transportation, forecasting, network optimization, and inventory management [1].
The primary purpose of this review is to offer an incorporated decisive analysis and synthesis of the literature that provides a conceptual outline for the interrelation between SCM and its related activities in the RE production field.Consequently, this paper systematically investigates the variety of know-how and options by examining the literature on SCM, which can be exploited to utilize the available RE resources and motivate how supply chain views may boost the RE production expansion and identify a specific practical involvement between supply chain and RE production.In addition, researchers may use this study to catch a general synopsis of supply chain contributions in RE production previously shown with various methodologies and the scientific gaps existing in the published works.
Hence, this research inscribes the subsequent research questions: (i) What is the recent state-of-art related to SCM and RE production? and (ii) What are the prospective scopes in SC activities corresponding to the RE production?Thus, the two research questions are explored by precisely revising the relevant publications in different scientific databases are the leading research goal, which could be accomplished based on the systematic review conducted on the published literature in the specified research area, focusing on the period from 2010 to 2020 in order to encompass the most updated knowledge.
The arrangement of the remaining review sections is as follows: Section 2 pinpoints the relation between SCM and RE production; Section 3 outlines the approach used to conduct this study; Section 4 clarifies the analysis and results of the reviewed literature.Meanwhile, the limitations of this study and future scopes for the prospective works of this research discipline are specified in Section 5, followed by the practical and managerial implications in Section 6; then, the conclusion and future research prospectives are delineated in the last section.In the end, the appendices are separated into (A) demonstrates the distribution of literature according to the covered regions studied, and (B) comes up with the classification of the literature according to their research perspectives.

SCM and RE Production
The field of SCM expands to various interdisciplinary ranges: economics, business, organizational science, industrial psychology, and operations research.As a result, from one side, the concerns in SCM regarding knowledge remain to enshrine attention from an assortment of study areas.On the other hand, supply chain administrators have recognized the incorporation of environmental, economic, and social aspects; thus, they are concerned about green and supply chain management sustainability [29].Businesses initially use SCM to help regulate the chains of events related to both products or services [30].Hence, from an energy production perspective, SCM presents a combination of principles that qualify active administration of flow between the place of usage (transference to the end clients) and the location of raw materials [27].
There are various approaches and methodologies in the published studies revealed that the SC in RE fields has a significant role in economic growth [29], with the fact, SC for RE deployment shares similarities to other typical supply chain systems [9]; therefore, the Renewable Energy Supply Chain (RESC) term is created, which is defined as "the transformation of raw energy into usable energy and involves an effective set of management principles from the acquisition of energy resources to the consumption of usable energy" [20].Consequently, the RESC fundamentals include information flows and physical and financial streams [9].
The RESC can be divided into three phases: upstream, production, and downstream, mainly consisting of five sub-phases: procurement, generation, transmission, distribution, and demand.These phases cover all processes along the RESC from raw materials until converted into final useful products.Hence, RESC main objectives are to provide a regular and consistent supply of raw materials and promote RE technologies [20,21].In this sense, SC behavior should consider main elements like suppliers, prospective locations, prospective consumers, and the capacities of service and their areas from the RE facilities to the end-users [9].
The principles of SCM can handle the challenges of energy production generally via two groups: organizational performance and operational performance [27].SCM is imperative for two specific areas, (i) Characterizing the organization that shapes the energy production supply chain sectors, managers must handle the geographical distribution of minor actors and large organizations from the place of raw materials to the site of usage, recognizing demand diversity, and to offer a tactic for management of buyer-supplier interactions.(ii) Sharing the features of perishable goods for numerous lower-valued energy carriers, expressly the raw materials, especially in biomass.Thus, practices have to be designed around operational performance (sizing, timing, eco-efficiency, and capacity utilization) [31].Hence, this review is conducted to discover how scholars handle such previous aspects, especially for renewable energy deployment.

Literature Refinement
The approach used to conduct the review has multiple procedures; firstly, the manual search was employed to exclude word search restrictions that could avoid pertinent publications.Then, the search and review criteria were conducted on two separate topics, which are supply chain management and energy production, considering the renewable energy supply chain.Hence, all relevant keywords related to the specified topics wereidentified according to synonyms and main concepts to ensure the search is comprehensive.Therefore, keywords such as "logistics", "supply chain", "energy production", and "renewable energy production" were used during the publications gathering and filtering processes.The search strategy combines all concepts into a singular search, as the search protocol used was "supply chain" OR logistics of "energy production" OR "renewable energy production".Finally, the search criteria depended on titles, abstracts, keywords, highlights, and subject terms.
The Egyptian Knowledge Bank (EKB) has facilitated institutional access to the full texts of the searched papers from various data sources that contain the most popular scientific databanks like Web of Science (WoS), Scopus, Google Scholar, as well as ProQuest.Additionally, the integral software is used to manage the citation of references.The search was restricted to articles in English from 2010 until the end of 2020 and most closely related to aspects for a good grasp of renewable energy production and the supply chain systems.The following Tables 1 and 2 represent the narrowing process and ignore the repetition; hence this study focused on 330 filtered publications out of 378 resulting from the searching processes.The coding criteria have been established to assess the content of the scientific works refined by searching on the key concepts identified instead of looking only at the actual words, which a computer algorithm cannot as yet accomplish.It involves coding for inclusion or exclusion that makes a judgment based on the title and abstract whether the study under consideration fits the predetermined inclusion criteria; therefore, they should be retained or discarded from further analysis.Hence, the authors manually executed the exclusion phase by reading each paper abstract to determine and assess its quality and to what extent the publication was relevant to the intended criteria.Figure 1 explains the dataset processing phases that consist of three main phases followed in conducting this study that started with the inclusion phase and ended with the analysis phase.As a result, the study focused on 272 works out of 330, including 136 peer-reviewed scientific papers, 81 postgraduate dissertations, mainly Ph.D. theses, 37 conference papers, 13 book chapters, and 5 technical articles, as demonstrated in Figure 2. Hence, the research process includes the maximum number of relevant publications that explain the relation between RE production and the supply chain systems from one side and the importance of well concurrence of RESC systems from the other side.In addition, the review shows a portentous increase in recent years, as illustrated in Figure 3.As a result, the study focused on 272 works out of 330, including 136 peer-reviewed scientific papers, 81 postgraduate dissertations, mainly Ph.D. theses, 37 conference papers, 13 book chapters, and 5 technical articles, as demonstrated in Figure 2.

Limitations and Prospective Scopes
This review has several limitations; considering the descriptive data and the results presented in tables and figures, the statistical analysis is not deployed.Besides, the four scientific search engines only used: WoS, Scopus, Google Scholar, and ProQuest, which might not be enough to cover all relevant published works comprehensively.However, the study has offered a wide range of published scientific works related to such a field without harming the entire study and its reputation.In addition, the publications divergence produced from the searching in different search engines with various datasets and filtering procedures that cannot assure the quality levels of filtered works is the same.In the future, the prospective studies can enhance the searching strategies by more determinations for the databases used for conducting such research and assess the reliability and validity of results using statistical analysis and focusing on the datasets with the identical strands to ensure the quality of the publications gathered.

Practical and Managerial Implications
This review classifies and categorizes all relevant concerns related to SCM for energy production, with more concentration on renewable energy resources.Accordingly, the study has organized this relationship into two main categories with eight key sub-branches to facilitate the literature refinement process and to determine the research gap regarding this field accurately; thus, the findings illustrated from this classification have led to clarify the scientific research gaps, which might be covered thereafter in the future studies which are the critical intent of this study.Additionally, although the increasing number of publications regarding SCM and RE production.However, according to the analysis of the published works and their classifications highlighted in this review, it could be determined that:

•
Various aspects of the supply chain and logistics activities within the RE production field are adequately covered in the literature, such as managing, controlling, and modeling the supply chain for biomass, wind, and solar power production.However, it needs more attention for the rest of the renewables (i.e., geothermal, hydropower, and tidal).

•
Most of the studies concentrated on bioenergy, approximately 68% of the screened literature addresses this category.Additionally, managing the supply chain of biomass products to produce bioenergy such as bioethanol, biofuel, or biogas was the central theme within this category as it represented about 65% of the published works in this area.Hence, increasing the scientific contributions regarding the other disciplines is required, especially the intelligent logistics system for biomass production such as optimization and modeling, intelligent transportation systems, or blockchain and information control.

•
Some regions were sufficiently studied, while others need more adequate research in such a field; for example, the highest ratio goes to North America and Europe.At the same time, in contrast, the West of Asia, the golf area, and Africa have the lowest research studies.However, those areas have good opportunities to establish and develop renewable energy farms.Moreover, due to their nature, location, and weather, they might also be hub areas in renewable energy production.Notwithstanding, most of these areas comprise developing countries, and most of them have a deficiency in energy resources.

•
Transportation; as one of the logistics activities, it is covered only in biomass production because the biomass production scope is the only field that has physical movements, while the rest of RE transportation operations are via networking and grids, so no physical movements exist but only designs and planning for such networks that require engineering techniques.Nevertheless, the research community should contemplate supply chain activities of non-physical activities such as optimal network planning, network capacity optimization, and timely distribution and delivery.
Furthermore, the results of this review show some positive managerial implications in the existing literature for business sectors, especially for supply chain service providers to reduce dependency on traditional energy.Simultaneously, the analysis presents that using renewable energy in supply chain activities to be green operations was one of the streams covered during the last decade.Hence, they are required to adjust their activities and strategies for sustainable expansion based on renewable energy in order to sustain their business by merging renewable energy usage into their services to reduce carbon emissions in the long run and achieve sustainable business performance.However, boosting the supply chain activities to be green is restrained by some obstacles, such as the transformation cost, governmental procedures, organization characteristics, service limitations, etc. [26].Thus, the proper understanding of these barriers is the key success factor in executing the green supply chain activities and applications.

Conclusions and Future Research Prospective
The relationship between SC and RE technologies development has been a subject of growing attention in the previous published scientific works.Although the literature related to the logistics and supply chain practices associated with the renewable energy context has been amalgamated with transportation, forecasting, network optimization, and inventory management; however, the most concentrated on biomass as it has more materialistic activities than the others.Therefore, according to the analysis conducted, the oncoming research may opt and dedicate an in-depth consideration via empirical examinations, proper modeling, and simulation tools to cover the types of RE and their related supply chain and logistics activity, which are rare in the literature, such as geothermal, hydrogen, hydropower, tidal, and HRES.Additionally, the most newly cradle aspects that need more investigation due to their importance principally for a sustainability concept, such as intelligent logistics for RE production, using simulation tools to optimize the supply chain activities within RE production, the supply chain for maintaining the RE systems (i.e., maintenance supply chain).2011) [3,16,30,33,40,44,63,64,67,71,76, Table A5.Oceania (Region 5).
