“…The two main steps of this study are to determine (a) weights of criteria for the assessment of energy alternatives, and (b) performance scores of energy alternatives for each criterion and a city of interest. Previous research investigated several aspects in the assessment of renewable energy, including environmental concerns [18], incentives [6], investment strategies [3][4][5], jobs and economic development [11], and research development [34]. These perspectives may be grouped into five main criteria (Table 1).…”

“…Financial support systems in Spain were also identified in the study. Another study on the European side was conducted by Bulavskaya and Reynès [11]. This study focused on macroeconomics and job creation potential of renewable energy technologies in the Netherlands.…”
Background: Cities around the world face a great challenge in establishing a long-term strategy for the development of energy alternatives. Previous research tried to identify renewable energy across many different cities. Because each city has unique characteristics in terms of geographic and environmental conditions, population, economic development, and social and political environment, the most sustainable energy source for one city might be the least sustainable for another. Methods: This research develops and implements a systematic approach to assess renewable energy and identify the energy alternatives for a city using the analytic hierarchy process. The methodology integrates experts' input and data analytics and helps decision-makers form long-term strategies for renewable energy development. Results: The decision support system is applied to three cities, Chengdu in China, Eskisehir in Turkey, and Chicago in the United States of America. Results show that improving energy efficiency and development of solar and wind energy are the most preferred energy alternatives whereas nuclear and hydroelectric are the least preferred energy alternatives for these three cities. Conclusions: The results of this study are in line with decades of research and development in energy alternatives and show a clear direction for the future development of energy alternatives around the world. There are differences in the rankings of energy alternatives for different cities, indicating that it is necessary to apply the decision support system developed in this study to help form customized energy strategies for cities with unique characteristics.

“…The impacts of renewable energy on the economy include direct and indirect ones. A large body of literature focuses on the direct impact of renewable energy [2,11,19,37,38]. Some also assess the direct and indirect impacts of renewable energy from the life cycle perspective [20,39].…”
It is believed that renewable energy may become a dominant energy in the future. However, whether renewable energy can promote industry development like the use of fossil energy is still unknown. This paper uses social accounting matrix (SAM) multiplier model to analyze the economic effects of renewable and coal energy in China. The transmission mechanisms of renewable and coal energy on production factors are also compared from the perspective of sector industry chain based on the structural path analysis (SPA) analysis method. We found that; renewable energy plays a stronger role in promoting the national economy than coal energy. Meanwhile, renewable energy can better promote the upgrading of the industrial structure compared with coal energy. Additionally, renewable energy affects economic development, mainly through the intermediate industries such as electrical machinery manufacturing and transportation, warehousing and service industries. These findings provide further insights into the influence path of renewable energy, which yields important implications for reasonably designing and choosing new energy development planning.
“…Numerous studies of GT have been performed in technological fields [17] such as renewable energy [24][25][26], solar cells [27][28][29], fuel cells [30,31], and water management [32,33]. Similarly, numerous studies have been conducted on GT and green innovation from an economic perspective; examples include an analysis of green innovation factors in small and medium-sized enterprises in Korea [34] and a study on how environmental taxes affect the adoption of GT [35].…”
Section: Literature Review Of Green Technologymentioning
This study examined how green technology (GT) has evolved recently in the domain of national research and development (R&D) in Korea. The analysis considered social network analysis by using keywords of national R&D projects in environmentally benign ('green' in this paper) technologies. Data for analysis were collected from the R&D database of the National Science and Technology Information Service (NTIS). By selecting the official GT category in the NTIS's database, we gathered 53,896 GT R&D projects from 2011 to 2016 inclusive. By constructing a co-occurrence matrix with keywords, we conducted a centrality analysis (including degree, closeness, betweenness centrality) and visualized the network matrix to display a cluster map. This study presents the following findings: (1) the chronical trends of GT R&D, (2) focused fields of GT R&D, (3) the relations between keywords and GTs, and (4) the characteristics and problems in GT R&D. The paper ends with suggested policy implications to boost national GT R&D and to develop GTs in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
