Among these, the method that utilizes all sky imagers to estimate the direction of cloud movement above certain observation points is able to forecast fluctuations in solar irradiation with localized temporal resolution (∼30 min) through observation of shadows cast by clouds. The one-layered cloud is usually assumed in forecasting the direction of cloud movement. However, in reality, multilayered clouds may move in different directions in the sky. While such multilayered clouds may have effect on forecast accuracy, the extent to which multilayered clouds affect the solar irradiation and the generated solar power has never been reported. Therefore, the purposes of this study are (1) to give the dataset to know the effect of multilayered clouds and (2) to decide whether the multilayered clouds have to be considered in forecasting of solar irradiation. We analyzed the number of cloud layers and their effect on the solar irradiation, the generated solar power, and the clearness index through statistical analysis for all seasons in Toyohashi city, Japan. The dataset used to analysis includes data with 4381 h. The analytical results show that multilayered clouds were observed for ∼40% of the daytime duration even in winter. In addition, the results show that multilayered clouds were observed even when the solar irradiation, the generated solar power, and the clearness index were high, which suggests that the effect of multilayered clouds must be considered. In addition, it will be shown that the maximum number of cloud layers to be considered is 3 from statistical analysis.","PeriodicalId":485144,"journal":{"name":"Renewable Energy and Environmental Sustainability","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135783314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite research on its potential, quantitative measurement of leapfrogging is still required to determine those nations who have utilized energy leapfrogging's promise. In this study, we present a quantitative analysis using World Bank Open Database data from 2000 to 2015, creating an aggregated leapfrogging estimate (ALE) through renewable energy consumption (i.e., percentage of total energy consumption) and access to electricity (i.e., percent of total population with access). We defined the ALE by subtracting (renewable consumption % in 2000 / access to electricity % in 2015) from (renewable consumption % in 2015 / access to electricity in 2000). We included only countries whose renewable energy consumption increased during the study interval. Low-income countries collectively leapfrogged more than other income groups. Somalia (48.11), Togo (3.05), Eswatini (2.76), and Timor-Leste (1.04) all had ALE values greater than 1 (range: 1.7 × 10 −5 –48.11). We then conducted a policy analysis of these countries, confirming that all four had implemented renewable energy policies to create access to electricity. Our ALE accurately determined countries with energy leapfrogging, uniquely incorporating access to electricity, consistent with the fundamental purpose of leapfrogging as a strategy to increase access. Future studies are needed to understand why low-income countries with low ALEs and access to electricity failed to leapfrog in the past. Future studies are also required to design prospective quantitative statistical models predicting the outcomes of leapfrogging strategies.","PeriodicalId":485144,"journal":{"name":"Renewable Energy and Environmental Sustainability","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135649356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From when its first entrant arrived in 1955, development has been strong, and now it presents a complex industrial cluster with a wide range of industrial enterprises present, ranging from several major industrial multi-product manufacturers to those filling niche markets. Formal reporting of its economic contribution has occurred periodically over 40 yr, with one of the features of this being a series of four earlier iterations, and in this paper, the fifth, of a schematic diagram that identifies the enterprises engaged in symbiotic relationships and the nature of the associated materials exchanged. While the earlier reports concentrated solely on the traditional materials exchanges, the present study (data collected in 2021) went beyond these to gather additional data on what the authors are proposing as additional dimensions of the traditional Industrial Symbiosis framework. Aspects of Kwinana's skilled workforce, its support industry base, and its overlying governance framework were studied to provide insights into what role they play in explaining why some industrial clusters appear to provide a supportive business environment, and why other clusters struggle to gain momentum. The new study identified that the novel posited dimensions of Industrial Symbiosis are interlinked at the precinct level, and that at the macro (societal) level, they combine to contribute to the effectiveness of the Circular Economy.","PeriodicalId":485144,"journal":{"name":"Renewable Energy and Environmental Sustainability","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135317638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People in developed nations need to reduce their carbon footprints six-fold to stabilize CO 2 levels in the atmosphere. This research develops a method of estimating and monetizing mortality costs of items. Mortality Cost of Carbon Rate (MCCR) is the fraction of a climate change related death that would probably occur over 80 yr with a specified temperature trajectory, from the emission of 1 tCO 2 e. MCCRs are allocated to items on an exponential curve generated from two researched MCCRs corresponding to temperature trajectories. MCC of an item (MCCI) is its MCCR multiplied by its life cycle CO 2 e emissions. The method was applied to the 2020 Australian passenger vehicle fleet and 6 vehicle types. MCCI was compared to mortalities from crashes and exhaust pollution. Total fleet mortality was estimated at around 62,000/ year. Mortality from 2020 CO 2 emissions will probably be around 56,000 - 75 times higher than crash deaths - with uncertainty range 28,000 to 106,000, compared to toxic exhaust emissions 5,600 and crashes 750. A Sustainable Personal CO 2 Footprint' of 1.5 t CO 2 / person/ year was set as a benchmark for sustainable consumption. Electric buses, E-bicycles/ scooters and micro-EVs are sustainable and if universally adopted, would reduce mortality by 96%. Social Cost of Carbon Mortality Rate (SCCMR) monetizes MCCR using a global Value of a Statistical Life Year. SCCM of items (SCCMI) is calculated as for MCCI. Research estimates of MCCR and SCCMR vary according to assumed causes of mortality, temperature trajectories and discount rates; many are underestimated as they exclude some mortality damage sectors. Toxic exhaust emission and crash mortalities were monetized using the Australian Value of a Statistical Life. Total social mortality cost of a large 4 wd ICE diesel SUV was approximately $6300, current fleet average $4800, and micro-EV $400.","PeriodicalId":485144,"journal":{"name":"Renewable Energy and Environmental Sustainability","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135504961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The project site lies in al-Azbakeya historical garden that lost more than 75% of its area to concrete structures, it is a part of historical Khedival Cairo that suffers from urban deterioration, high population, and pollution [1]. The project is a complex building that aims at converting al-Azbakeya garden into a hub of sustainable and green urbanism [2]. It also targets social and economic sustainability by tackling the problem of street vendors. The design approach is reached through site analysis to determine the challenges and opportunities of the site, and the project's targeted environmental, social, and economic impacts. Then, a functional program is established to integrate governmental and non-governmental organizations to provide collaborative sustainable solutions. The objectives are met by using four architectural design features: pixel-like interlocking masses, natural light, small buildings with local and recycled materials, and natural materials integrating with the garden context. Sustainable technologies are used in irrigation, energy use, and water use to ensure environmental sustainability [3]. Environmental analyses are developed to test the project's efficiency using Digital software plugins as Revit-Insight. Area Analysis is also carried out to check area distribution among different functions, while the Circulation Analysis shows best entrances and passages for pedestrians. The results are adding around 13 000 sqm (68% of total area) of green areas to the compact urban area, providing developed businesses in a regulated retail area for street vendors converting their problem into an asset supporting the Circular Economy Strategy, and reviving the livability of the community by cultural spaces like bookstores, open theater, and a second hand market promoting smart reuse. The project fulfills its objectives and meets the sustainable development goals 6, 7, 8, 11, 12, 13, 15, and 16.","PeriodicalId":485144,"journal":{"name":"Renewable Energy and Environmental Sustainability","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135007938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
