This small geographical area is planning to expand its RES share to reach 15 % of the national electricity demand by 2030. This study investigates the effects of two large sandstorms on different RESs employed in Kuwait: (1) photovoltaic (PV) power plants, (2) concentrated solar power (CSP) plants, and (3) wind turbines (WTs). Sandstorms exhibit crucial weather-related characteristics as the solar irradiance decreases significantly during storms whereas the wind speed increases. These two weather parameters are the fuel used in RESs. Therefore, the power produced by the PV and CSP plants decreases substantially, whereas the power produced by the WT increases to its rated value for several hours. This causes a decrease in the total energy generated by the PV and CSP plants, in contrast to the WT plants, which always overperform against their typical daily average values. By comparing the daily energy average of May 2021 with no major sandstorms present, the energy generated by the PV is 83.3 % (Storm 1) and 49.1 % (Storm 2), whereas the energy generated by the CSP is 100.4 % (Storm 1) and 18.2 % (Storm 2). Conversely, the energy generated by the WTs is 198.6 % (Storm 1) and 237.6 % (Storm 2). This study illustrates one of the benefits of employing hybrid RESs. Different hybrid configurations are investigated with the PV-WT configuration showing great potential with near-constant produced power and overperformance in the total energy generated.</p></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":null,"pages":null},"PeriodicalIF":5.5,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141263759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To help mitigate these impacts, the Jet-Flame forced draft cookstove retrofit accessory was designed to apply jets of high-momentum air into the fuelbed of existing cooking stoves to improve combustion efficiency and cooking speed. Paired with a rocket cookstove and solar home power kit and light, the device usage and resulting changes in cooking time and kitchen PM_2.5 concentrations were measured in 40 households in Malawi across four study phases using an integrated suite of sensors. Results revealed cooking time across all households was reduced by 29 % upon introduction of the Jet-Flame. Households that used the Jet-Flame more than 80 % of the time in a rocket stove showed an average reduction of 64 % in kitchen PM_2.5 concentration relative to the baseline. Battery power consumption data showed the daily power consumed by the Jet-Flame(s) (200 mAh) was about 10 % of the power consumed relative to the lights and phone chargers (1000 mAh each), suggesting a low power draw by the Jet-Flame and remaining battery capacity available for other uses that are valued by these unelectrified households. Finally, the estimates of carbon dioxide equivalent (CO_2e) emissions reductions earned by implementing the stove and Jet-Flame kit, including fuel savings and reductions in black carbon fraction from 38 to 19 % measured in the laboratory, indicated a reduction in 5.7 tons of CO_2e per stove year from baseline at a fuel harvest non-renewability of 26 % when using the stove and Jet-Flame together. These findings indicate this suite of technologies may potentially help to affordably address global goals for climate, health, and gender equity; especially if supported by carbon and co-benefit financing.</p></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":null,"pages":null},"PeriodicalIF":5.5,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141231922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a comprehensive exploration of key indicators including biogas production, waste levels, conversion efficiency, and operational stability, utilizing fuzzy paraconsistent logic, enhanced approaches to energy recovery and environmentally responsible waste management are identified. This study examines biogas production in different urban scales, assessing its correlation with key indicators. Notably, a consistent pattern of moderate energy generation throughout the year emerges, regardless of city size. This uniformity underscores the potential for optimizing waste-to-energy conversion and highlights the role of effective waste management in pollution mitigation. Furthermore, a direct correlation between city size and generated biogas underscores the potential of larger urban areas to utilize substantial waste volumes as an energy source. Consistency in waste levels across diverse contexts further emphasizes the positive environmental impact of this approach. Conversion efficiency exhibits predominant uniformity, indicating consistent energy recovery strategies across various cities. The direct link between operational stability and conversion efficiency highlights its role in optimizing biogas production. This holistic approach underscores the urgency of adaptive strategies and sustainable practices for a cleaner environment and enhanced energy efficiency. Future research can explore the economic implications of energy recovery strategies and delve into their long-term social and cultural viability.

The Democratic Republic of the Congo (DRC) has one of the lowest electrification rates globally, placing undue constraints on the country's small enterprises. Efforts are currently underway to improve electricity access in the DRC and throughout sub-Saharan Africa using decentralized solar mini grids. Their effect on small enterprise energy access and enterprise operations remains largely unexplored, particularly in urban settings. We address this gap by evaluating the impact of a recently established solar mini grid on small enterprise operations in an un-electrified district in the city of Goma. We use a case-control study design to assess the adequacy of electricity supply in a sample of 128 qualitatively similar small enterprises. Cases include enterprises connected to a newly constructed solar mini grid operated by a private energy service provider. The control group includes enterprises connected to the long-standing parastatal utility grid. We analyze indicators of electricity availability and usage, reliability, perceived affordability, overall satisfaction, and value to construct a profile of electricity access and supply characteristics across the two groups. We find that electricity from the solar mini grid provides significantly improved energy access compared to the existing public utility evidenced by more hours of electricity, consistently strong voltage levels, and fewer outages. However, solar energy is more expensive. Our results confirm that investment in decentralized solar mini grids is a viable solution to improve electricity access for small enterprises in African cities. DRC is heavily investing in decentralized solar mini grids as an alternative to building out grid connectivity.</p></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":null,"pages":null},"PeriodicalIF":5.5,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0973082624000905/pdfft?md5=2693f19b1b4e0e90ad46b9c8f397b386&pid=1-s2.0-S0973082624000905-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141239380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a numerical study on the performance of a photovoltaic-pumped hydro storage (PV–PHS) system in a high-rise residential building context. The designed system operates in the Mediterranean climate of the city of Oran, Algeria. Real data on the building's electricity demand and the region's actual climatic conditions are used for system sizing and simulation. A Fortran programming code is developed based on an energy management strategy and a realistic mathematical model that considers all system losses. The performance analysis demonstrates that the PV fully meets the residence's daily load demand for 7 h, reducing reliance on the public grid. Furthermore, approximately 50 % of peak evening consumption is supported by the storage capacity. Accordingly, the PV–PHS coverage rate is around 46 % throughout the year, with an overall PHS efficiency of 60 %. Parametric analysis indicates that enlarging the discharge pipe reduces system losses and that increasing the storage volume improves the coverage rate. Other results reveal that the coverage rate is more sensitive to variations in load demand than to building height, and remains limited by installed PV capacity. The economic study was carried out for three different scenarios based on electricity price and feed-in tariff. In the most favorable scenario, the system achieves a payback period of 8.5 years and a net present value of 94,904 euros, making it economically viable and profitable. These results highlight the performance of a PV–PHS system in a high-rise residential context while providing the necessary information for the design and optimization of such systems. They can also guide policy-makers in adjusting tariff policies to enable private investors to achieve economic profitability.</p></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":null,"pages":null},"PeriodicalIF":5.5,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141239373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
