Additionally, in metropolises like Istanbul/Türkiye, traffic congestion is one of the most significant issues. Taking these factors into account, there is a need to promote the use of public transportation vehicles and electrification of the system. This study focuses on the optimal energy management of multi-swap stations (MSSs) with photovoltaic (PV) systems serving an electric metrobus (EM) line. The presented framework is modeled using a mixed-integer linear programming (MILP) approach. In this system, when the batteries of the EMs on the route are running low, they can come to the stations where the swap operation can be performed, allowing them to exchange their batteries within the passenger boarding and disembarking times. Besides, the power transferring between batteries at swap stations is considered, which helps ensure flexible operation. The PV systems can be utilized for battery charging, and surplus energy can be sold to the power grid. Various test studies are conducted using data from the Istanbul Z34 metrobus route in this research. According to the results obtained from the study, the proposed structure demonstrates the effective operation of swap stations serving EMs. Doubling the PV capacity increased the profit to 6103 Turkish Liras (TL). In October, the highest energy selling revenue of 4791 TL was recorded due to elevated electricity prices. Inter-battery power transfer provided cost savings, with up to 50 TL saved in January, while prioritizing PV energy sales to the grid further reduced operating expenses.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"86 ","pages":"Article 101722"},"PeriodicalIF":4.4,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715917","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}

National MSW output in Malaysia is estimated at 1.17 kg per capita. This issue is crucial since 29 Malaysian landfills produce 200 thousand tons of MSW per month, releasing greenhouse gasses (GHGs). Anaerobic digestion (AD) may convert MSW into biogas to lower its organic content for landfill disposal. The AD system aims to produce biogas from domestic organic waste to create a circular economy. This study also surveyed Seremban, Malaysia, inhabitants on MSW composition and disposal. The organic fraction of MSW was subjected to the pilot-scale 500 L AD reactor, resulting in a daily average biogas production of 92–262 L, where a significant proportion of the biogas constituent, ranging from 60 to 70 %, is CH<sub>4</sub>. Biogas production was shown to be enhanced by an increase in feedstock, as seen by a greater daily intake of 5 kg. <em>SimaPro</em> was then used to quantify the resulting GHGs emissions from the AD process. The results indicated a value of 0.215 kgCO<sub>2</sub> equivalent for every 5 kg food waste that underwent processing. The proposed AD system exhibits a remarkable 80 % improvement in GHG emission reduction per kg of food waste processed, in comparison to existing methods. A thorough familiarity with organic waste's make-up and disposal patterns is necessary for its effective implementation. Statistics revealed that only 35.45 % of Seremban residents disposed of MSW daily, and that waste segregation rates were below 50 %. As a percentage of MSW, organic waste account for 55 %, or 0.35 kg/person/day. With a daily capacity of 20 kg for processing food waste, the proposed AD system is highly dependent on a constant organic waste supply. Instead of continuing to be inept at waste management, this effort offered an alternative. MSW poses significant environmental concerns, but the proposed pilot-scale AD system shows promise in addressing these issues and encouraging sustainable habits in local communities. At the very least, this could result in a reduction in MSW sent to landfills and GHG emissions for residents of Seremban.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"86 ","pages":"Article 101718"},"PeriodicalIF":4.4,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715959","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}

Results indicate a significant energy-related employment effect. We find an increase in non-farm employment participation among women in households that use clean energy for cooking. In particular, clean cooking energy is associated with a higher likelihood of women working in wage or full-time employment. The mechanism underlying the increase in female employment is that clean cooking energy leads to better health and a reduction in the prevalence of serious illness. Further evidence suggests that the effect on employment participation varies by women's age and family size. To improve the well-being of rural women in developing countries, this study emphasizes the necessity for policy support to increase access to clean energy for rural households.

The current business model is traditional, that is, the public sector exclusively purchases electricity from distribution companies at fixed rates. However, the electric sector business model has become outdated by the development of renewable distributed generation sources, energy storage systems, and competitive retail electricity markets. In this context of grid-edge technologies, where decarbonization, digitalization, and decentralization urgently promote energy transition, big data analytics applied to the BDGD can be useful for proposing more advanced business models for the public sector, focusing on enhancing electricity affordability, efficiency, and government sustainability. Therefore, this study contributes to an innovative framework called BDA4ES (Big Data Analytics for Energy Sustainability) by (i) creating a methodology that enables researchers to access the BDGD, process the data, and add complementary data, and (ii) conducting a thorough evaluation of investment opportunities in photovoltaic (PV) generation to make the Brazilian public sector more sustainable (financial, social, and environmental). Preliminary results demonstrate that by investing in PV generation, the Brazilian public sector could save R$ 476 billion (US$ 95 billion) over 25 years, representing a return on investment of 366 %, thus avoiding 46.2 Mt CO<sub>2</sub>-eq of global warming potential (GWP), representing 3.4 % per year of the annual Brazilian carbon footprint on electricity generation. Moreover, when assuming an interest rate of 4.4 % (2019 average Brazilian basic interest rate – SELIC) the discounted payback time is 6.3 years (again, between 1 and 2 political mandate of 4 years), and the Net Present Value (NPV) is R$ 233 billion (US$46.5 billion) over 25 years. From this perspective, considering the overall socieconomical, environmental and political benefits, it becomes evident the public sector energy sustainability project's potential. The conventional optimized tariff model (TAROT) indicates that such a project would imply regulatory tariff increases up to 2.52 %, which is not particularly worrisome. Therefore, the results demonstrate the economic, social, and environmental viability of deploying PV systems to supply green electricity to the public sector, thereby enabling sustainable cities.

Numerous studies have examined how clean cooking technology can, under the right circumstances, reduce household air pollution and shift household time use. Yet, empirical research on the adoption and impacts of bioethanol, an emerging clean cooking fuel that is frequently promoted in policy dialogues, remains limited and largely descriptive. Thus, this paper evaluates the effects of a large-scale, UNIDO/GEF-sponsored ethanol promotion program implemented in Dar es Salaam, Tanzania. To mitigate against bias from non-random selection into ethanol stove ownership and confounding by observable factors that may influence the outcomes of ethanol stove adoption, we apply multiple regression and matching methods to analyze survey data collected from 844 households. We document increases in cooking time with ethanol fuel and primary use of ethanol stoves, indicating that this technology was taken up by targeted households.
