In order to identify environmental problems and develop necessary policies, it is necessary to consider the environmental performance of countries. Therefore, measuring the environmental performance of countries is of great importance. One of the prominent indices in measuring environmental performance today is the Environmental Performance Index (EPI) developed by Yale University. The main purpose of EPI is to quantitatively measure and compare the environmental performances of countries in order to monitor their progress in environmental sustainability. As of 2022, EPI consists of three main criteria: climate change, environmental health, and ecosystem vitality. In this study, Turkey’s environmental performance was evaluated using the Entropy-based PROMETHEE method with international EPI 2022 data. Subsequently, the environmental performances of Turkey and other Eastern European countries were compared in terms of criterion superiority to determine their strengths and weaknesses. In this context, various sub-criteria were analyzed under main criteria such as climate change mitigation, air quality, sanitation and drinking water, heavy metals, waste management, biodiversity and habitat, ecosystem services, fisheries, acid rain, agriculture, and water resources. As a result of the analysis conducted as of 2022, it emerged that Turkey generally exhibited weak environmental performance among Eastern European countries and there is a need for improvement in each criterion. Giving priority to criteria such as Climate Change Mitigation, Sanitation and Drinking Water, Biodiversity and Habitat, Fisheries, and Acid Rain, in which Turkey obtained the lowest scores in the ranking, would be a more strategic approach.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 1","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000435/pdfft?md5=ddd6e2852eec60a9d2983143bdc68e8e&pid=1-s2.0-S2949736124000435-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141853453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the challenges faced by wind generators is operating with significant wind speed oscillations. A wind generator with a large moment of inertia increases the time constant in rotational speed control and delays the tracking of the optimal operating point. This delay could reduce generated power by up to 40% or more. There are numerous regions in Japan’s inland areas where average wind speeds exceed 6.5 m/s. However, frequent fluctuations in wind speeds make wind power generation challenging. Therefore, this paper proposes a control algorithm suitable for wind turbines operating under unstable wind conditions. Higher rotational speeds are required to convert sudden high wind speeds into higher power output, especially when wind speed oscillations are large. Hence, the proposed algorithm focuses on maintaining the rotational speed during periods of unstable wind conditions to improve generation efficiency. The effectiveness of the proposed control method for wind turbines is verified through numerical simulation results. The novel control algorithm aims to promote the spread of wind turbines in areas with unstable wind conditions by overcoming these disadvantages.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 1","pages":"Article 100113"},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S294973612400040X/pdfft?md5=6c63d92516ceccedd445e4ed196301ac&pid=1-s2.0-S294973612400040X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141838841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evaluating the ”greenness” of a manufactured product is a complex task due to data availability, varying definitions of ”green” products, and diverse environmental impacts. This research addresses this challenge by identifying, classifying, and prioritizing Key Performance Indicators (KPIs) to assess green manufactured products, specifically within the Indian manufacturing context. A systematic approach was employed, incorporating Pareto analysis and the Full Consistency Method (FUCOM) to identify the most significant KPIs and assign them priority. Industry, academia, and customer perspectives were considered, resulting in distinct priorities. Industry experts prioritize economic aspects, while academia emphasizes health and safety. Customers focus on air quality and greenhouse gas emissions. This diversity of perspectives underscores the need for businesses to tailor their sustainability strategies to meet evolving customer demands while considering economic implications. The study identifies 30 vital KPIs crucial for evaluating green product manufacturing, encompassing dimensions like waste management, energy efficiency, workplace safety, and societal compliance. By considering these KPIs, businesses can make informed decisions to improve sustainability, reduce their environmental footprint, and align with consumer expectations. The findings provide a roadmap for businesses and policymakers to develop more effective strategies, targeting diverse stakeholder groups and promoting the production and use of green products. This research contributes to the growing body of knowledge in sustainable manufacturing and serves as a valuable tool for manufacturers in India and beyond, aiding them in navigating the complexities of manufacturing green products and meeting the rising demand from environmentally conscious consumers.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 1","pages":"Article 100114"},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000411/pdfft?md5=9ba3dcfdd281aa8cb40d9aa71230f8ee&pid=1-s2.0-S2949736124000411-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141842899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, compared with the literature correlation for solar still simulated mass, the Power model calculation was the closest, with a 12.4% variation. Furthermore, the study showcases that CFD is an economical, efficient, and easily diagnosable technique for designing solar stills.</p></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"2 3","pages":"Article 100105"},"PeriodicalIF":0.0,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949736124000320/pdfft?md5=83ae73746c59c2f5abec794096742036&pid=1-s2.0-S2949736124000320-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141325882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
