Therefore, reducing resource use through resource efficiency promises significant contributions to climate protection. This “climate-resource-nexus” has mostly been explored from a scientific, Global North-oriented perspective. The present study analysed potential interactions between climate and resource policy through literature review and exploratory interviews with experts from different world regions. It did not find a generic climate-resource-nexus policy. Scientific studies mostly address greenhouse gas emission reduction potentials of resource efficiency approaches, e.g., lifetime extension, material substitution, and recycling. Interview findings reveal that climate and resource policy measures will have to differ regionally to improve the relevance and fit and that silo culture may prevent an integrated climate-resource-nexus perspective. It is argued that creating an overarching line of policy reasoning through cross-departmental cooperation could help to overcome silos and grant flexibility to national and regional policy-making to adapt policies to their interviews with topical experts from international civil society and across different world regions. This paper presents findings from this research. The literature review reveals that policies-addressing academic publications mainly analyse potential GHG emission reduction effects of different material efficiency and circular economy strategies. However, the climate-resource-nexus appears to guide policy considerations hardly. Interview findings reflect this, as only a few interviewees mention mutual effects of climate protection and resource conservation policies. Those who mention interactions consider insufficient cross-departmental exchange and silo culture as reasons for the lack of climate-resource-nexus thinking in the policy. This kind of analysis could contribute to strengthening systemic nexus thinking in international climate and resource policy while also fostering a view on adapting policies to the needs of specific contexts. guideline questionnaires prepared to obtain the expertise of both regional climate and regional resource experts. Each questionnaire contained the same set of questions differing only in the policy measures exposed to expert feedback – climate protection policy for climate experts and resource policy (including circular economy) for resource experts. Furthermore, each questionnaire posed a question on the climate-resource-nexus, whether or not the measures discussed could impact resource use or GHG emissions in their regions.","PeriodicalId":46202,"journal":{"name":"Journal of Sustainable Development of Energy Water and Environment Systems-JSDEWES","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45119190","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}

While especially Sweden is a large electricity producer and net exporter, the Baltic countries suffer from a lack of capacity, which makes them highly dependent on trade. In addition, the present electricity mix of Estonia is very carbon intensive compared to the Nordic countries. There is a debate regarding nuclear power in Sweden. This paper explores four possible solutions for a Nordic-Baltic electricity system: with and without nuclear power in Sweden and with the current transmission network, as well as with a considerably expanded network. The impact on electricity mix, electricity prices, carbon dioxide intensity and import dependence in the Baltic countries from the EU transition to electricity systems with very low carbon dioxide emissions is investigated. The electricity and district heat market model Enerallt is used to quantify electricity prices, electricity trade and system costs. The results show that the development of the transmission network affects electricity prices and especially electricity trade in the Baltic countries. With transmission expansion, the demand weighted average prices in the Baltic countries increase from 62 €/MWh to 65 €/MWh and 70 €/MWh with and without nuclear power in Sweden, respectively. If transmission is expanded, phasing out nuclear power in Sweden can increase the revenue from electricity export by over 100% for the Baltic countries. However, significant new investment in wind power is required.","PeriodicalId":46202,"journal":{"name":"Journal of Sustainable Development of Energy Water and Environment Systems-JSDEWES","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45156734","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}

This scoping review examines communities in low and lower middle-income countries, and their use of renewable energy and flood warning systems. Its primary focus is vulnerable communities and how they can achieve hazard protection as part of sustainable development initiatives. The findings highlight that it is important to consider institutional, environmental, social/ethical, economic and technical indicators in developing a comprehensive understanding of the success or failure of a given system.

The multi-objective optimization dispatch problem is formulated to simultaneously minimize the operating cost, pollutant emission level as well as the power loss of conversion devices. While satisfying the system load and technical constraints, ensure high penetration of renewable energy and optimal scheduling of charging/discharging of battery storage system based on a fuzzy logic approach. The weighted sum method is adopted to obtain Pareto optimal solutions, then a fuzzy set theory is employed to find the best compromise solution. Ant lion optimizer method is considered to solve the formulated problem. To prove the efficacy and robustness of the proposed algorithm, acomparison of the performance ofant lion optimizer algorithm with other known heuristic optimization techniques has been investigated. The results obtained show that the proposed algorithm outperforms the other heuristic techniques in solving the multi-objective optimization dispatch problem. They also reveal that a better compromise between the considered contradictory objective functions is achieved when priority is given to the generation of the internal microgrid’s sources with an equivalent contribution rate of 68.45% of generated power from both fuel cell and micro-turbine, whereas the contribution rate of external grid is limited to 11.72%.","PeriodicalId":46202,"journal":{"name":"Journal of Sustainable Development of Energy Water and Environment Systems-JSDEWES","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48254105","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}

However, the ways in which communities benefit from such projects has been insufficiently studied, and the establishment process has been better documented. Moreover, relevant studies from developing countries are limited. This study was conducted to provide empirical evidence of the local impacts of community-scale renewable energy projects in a developing country, using the case of solar water pumping in Indonesia. A questionnaire survey was used to evaluate the socio-economic impacts perceived by the beneficiaries, and, subsequently, qualitative and statistical analysis were conducted. The results showed that the capacity of the local management team and satisfaction in saving money were perceived as the most significant impacts. However, the economic benefit of financial savings did not translate to welfare improvement. These findings provide insights that shows that (1) members of rural communities gained knowledge regarding the renewable energy technology through project deployment and (2) creating a support mechanism along with project deployment is crucial to achieve greater development opportunities in the context of rural poverty alleviation.","PeriodicalId":46202,"journal":{"name":"Journal of Sustainable Development of Energy Water and Environment Systems-JSDEWES","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47865765","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}

In this work, pyrolysis was applied to convert plastic wastes into oil yields. The physical and chemical properties of the obtained oil yields were analysed to find out whether their existence can be ascertained as the availability of standard fuel. This study was conducted in a real pilot plant using samples of low-density polyethylene plastic waste. The pyrolysis temperature varied at 200 °C, 250 °C, 300 °C, 350 °C, and 400 °C for two hours with a heating rate of 10 °C/min. Physically, the pyrolysis resulted in an oil yield similar to commercial fuel oils, having a light-yellow colour in all various pyrolysis temperatures. Gas Chromatography-Mass Spectrometry analysis showed the change in hydrocarbon chain and chemical molecular structures, thus influencing its physical properties. The increase in hydrocarbon chain length and in cyclic molecules and alkyl compounds as the temperatures increased led to the increase in density, viscosity, flashpoint, and octane number within the range of standard commercial oil fuels. Even though there was an increase in calorific values, these values were still under the commercial standard oil values. However, this can be tolerated by providing any oil-yield refined treatments.","PeriodicalId":46202,"journal":{"name":"Journal of Sustainable Development of Energy Water and Environment Systems-JSDEWES","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47859354","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}

Meanwhile, China’s energy consumption and carbon emissions associated with cement industry are expected to increase, as cement production is one of the most energy intensive industries. Introducing new and more pertinent technologies with better management, as indicated by government goals and measures, can improve energy efficiency and reduce carbon emission. However, many challenges and uncertainties in the cement industry have been addressed without considering several interconnected processes among sectors including industry, energy, construction, and services, which lead to little improvements in the industry. Nexus approaches are recognized as effective methods to simultaneously examine interactions among multiple sectors with various elements. This research intends to provide insights for future energy-cement-carbon emission nexus, through integrated assessment capabilities, related to China’s new urbanization planning toward 2050. Several challenges and uncertainties, including different trends in population growth, structural transformation of economic driving forces, and new but stricter policy targets for resource use efficiency and environment production, are put into multiple scenarios.
