This is due to the increasing prevalence of hypertension, diarrhea, and skin illnesses among the population residing in the southeastern coastal districts of Bangladesh. The necessity of establishing a drinking water supply system that is free from salinity for the people of the southeastern coastal region of Bangladesh is indisputable. It is crucial to assess the value of saline-free drinking water in order to provide useful information to policymakers and implementers regarding the willingness of the population to pay for such a service. The objective of this study is to estimate the Willingness To Pay (WTP) of people of Anowara Upazilla, a coastal sub-district of Chattogram district of Bangladesh for salinity-free drinking water supply. A cross-sectional study design was used to estimate the value of salinity-free drinking water in Anowara Upazilla of Chattogram by using the Contingent Valuation Method (CVM). A Systematic sampling method was employed to survey 410 households from six salinity affected unions of Anowara with structured questionnaire. This study additionally applied binary logistic regression model to identify the significant factors that influenced the WTP of the people for receiving salinity-free drinking water. The findings of this study revealed that 69% of the surveyed population from six salinity-affected unions of Anowara was willing to get salinity-free drinking water. The estimated mean WTP for salinity-free drinking water was BDT 222.50 per month per family. The logistic regression analysis revealed that household income higher than Bangladeshi Taka (BDT) 18,000 per month (p-value: 0.022), perceiving water salinity level as moderate (p-value: 0.002) by the respondent and family size with five members (p-value: 0.046) in the household were the statistically significant factors that influenced the overall WTP of the respondents. Moreover, most respondents preferred to have salinity-free drinking water supplied to their households through the piped network. The estimated aggregated WTP was BDT 6,228,887.50, which indicates that government intervention to supply salinity-free drinking water in Anowara Upazilla will be financially feasible if the project cost remains less or equal to the aggregated WTP. The findings of the study will be useful to the environmental practitioners of Bangladesh.</p></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"13 ","pages":"Article 100272"},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772427124000032/pdfft?md5=98dd5db4d367b441644996aec87939f8&pid=1-s2.0-S2772427124000032-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139814980","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}

RNG is gaining popularity as a sustainable alternative to fossil fuels, but it is facing significant obstacles in the market. One of the main challenges for RNG developers is obtaining a consistent and reliable supply of feedstocks, which is complicated by high production costs and the need for more infrastructure. The paper examines the various types of feedstocks used in RNG production, including agricultural waste, municipal solid waste, and wastewater treatment plant sludge. Each feedstock has its unique challenges, such as transportation costs, storage requirements, and processing technologies. Furthermore, RNG production requires significant capital investments, which can be challenging to secure, particularly for small and medium-sized enterprises. In addition to feedstock and financing challenges, RNG developers face regulatory hurdles. RNG projects are subject to various federal and state regulations, including the Renewable Fuel Standard (RFS) and state-level Low Carbon Fuel Standard (LCFS) programs. The RFS has limited RNG's growth potential due to its focus on corn-based ethanol, while the LCFS program varies from state to state, creating regulatory uncertainty for RNG project developers. Despite these challenges, stakeholders are taking steps to promote the adoption of RNG. Industry groups are advocating for supportive policies, RNG developers are investing in infrastructure and developing new technologies, and policymakers are exploring options for expanding the RFS and implementing a national LCFS program.</p></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"13 ","pages":"Article 100270"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772427124000019/pdfft?md5=3fee40ee8dc8ac8e0bc0e0bf72f25751&pid=1-s2.0-S2772427124000019-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139675436","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}

An innovative system was devised to simultaneously produce cooling, electricity, hydrogen, and freshwater by combining an absorption chiller, reverse osmosis, PEM Electrolyzer, and two double Organic Rankine Cycles. To assess the impact of local weather conditions, case studies were conducted in the cities of Hong Kong (China), Bandar Abbas (Iran), Tepic (Mexico), and Melbourne (Australia). Computational modeling employed EES software, and optimization using Response Surface Methodology aimed to enhance system performance and minimize costs. The geothermal system was engineered to meet the electricity demands of residential households during peak consumption. The optimal results demonstrated that the proposed geothermal system, in its most efficient configuration, could achieve an exergy efficiency of 73.17 % and an energy efficiency of 25.25 % while operating at a cost rate of 74.36 $/h. An economic analysis revealed that among the system components, ORC1 unit and PEME incurred the highest costs. Additionally, the PEME, evaporator, and absorption chiller were identified as the main contributors to exergy destruction. The total exergy destruction rate of the proposed geothermal system is 1840.7 kWh and the total cost rate of the system is 51.73 $/h. Lastly, the assessment of the suggested geothermal system across the studied cities indicated that it performed most effectively in Melbourne, Australia. The results of the study of the production capacity in the four study cities showed that Melbourne has the highest production rate with a rate of 14,573 MWh, Tepic with a rate of 13,425 MWh, and Hong Kong with a rate of 13,174 MWh. The lowest annual rate with the amount of 12,784 MWh belongs to the city of Bandar Abbas. The environmental results showed that by producing 14,573 megawatts of electricity in the city of Melbourne, it is possible to expand 14 hectares of green space per year.
