This study analyzes Brazil's potential to produce green hydrogen from the grid, which is more than 85 % renewable, as well as its applicability as an energy vector within the transportation sector. The goal is to provide a novel global and unbiased technical, economic, and environmental assessment of grid-produced hydrogen for light and heavy vehicles in Brazil, i.e., cars and trucks, respectively. For reference purposes, the results for hydrogen are compared with the results for conventionally powered vehicles, i.e., electric- and fossil fuel-based. The results indicate that if Paraná state used all renewable energy generated in 2021 to produce hydrogen by electrolysis (22 GW of hydropower installed capacity), the amount produced would power its truck fleet (i.e., 134 ton/h or 1.17 Mton/year of hydrogen). The largest hydrogen demand comes from São Paulo state, which would have a deficit larger than 500 ton/h or 4.38 Mton/year of hydrogen. Furthermore, the 20-year total cost of ownership of a fuel cell powered vehicle is approximately 150 % higher than that of a gasoline or electric vehicle. Hence, currently, a hydrogen powered transportation sector is arguably challenging for the average Brazilian user. However, the entire truck and car fleets conversion would reduce by roughly 80 % the CO2 emissions when compared with fossil fuel powered fleets.

China has proposed the goal of achieving carbon neutrality by 2060. As a key emission unit, the transport sector is receiving more attention for its low-carbon transformation path. Due to the diversity of models and parameters, the core conclusions of existing studies are not entirely consistent. Based on the IPCC AR6 database, a framework for comparison analysis of multiple models is established to explore the existence of different results. It is used to evaluate the changes in low-carbon transition pathways, drivers and potential risks to the transport sector in the context of carbon neutrality. The results show that towards carbon neutrality, China's transport sector needs to accelerate the development of the railroad system, with different fuel substitution measures for passenger and freight transport. Electricity and hydrogen will become the main sources of energy in the transport sector, but increasing the proportion of hydrogen energy may lead to a reduction in energy efficiency. The low-carbon transition of the transport sector was influenced by the path of China's carbon-neutral system. Fuel substitution will provide a more pronounced boost than other measures when more transportation emissions reductions are needed. However, as the power sector gradually shifts to renewable energy sources, mainly wind and photovoltaics, it could present a potential risk of uncertainty for transportation energy use. On this basis, the study provides meaningful policy implications for the low-carbon transformation of China's transport sector.

The electricity demand in Nepal, like in other developing countries, is increasing due to population and economic growth. To meet the increased demand, it is important to use cleaner fuels supporting global decarbonization efforts and clean energy transition. One way is through the increased use of renewable energy sources such as wind and solar energy. Despite being a Himalayan country, Nepal is blessed with significant solar resources. However, the scale of this resource has not been adequately and properly assessed. This article attempts to assess the solar PV potential using Geographic Information System (GIS) technology. A spatial analysis was performed to identify suitable areas by considering insolation, land use classifications and physical topography. The study found that Nepal has significant solar PV potential, with the ability to generate up to 552 TWh/year from ground-mounted, rooftop, and agrivoltaics, against a current demand of 12.3 TWh. The levelized cost of electricity was estimated to be in the range of $56 and $72 per MWh, indicating a huge potential to complement hydroelectricity, the main electricity source in Nepal. Of the three typologies examined, agrivoltaics appears to have a significant potential for producing clean electricity in rural areas without affecting the agricultural production. We recommend that to achieve net-zero emission targets, Nepal's policy framework should prioritize deployment of solar PV: ground-mounted PV for utility scale, rooftop PV for urban areas and agrivoltaic for rural areas. Robust Power Purchase Agreement rates and enabling policies could boost investment and accelerate the solar PV adoption. Finally, the methodology and the results presented can serve as a useful reference for undertaking similar studies in other countries.

To address the climate crisis driven by elevated GHG emissions, electrification of terrestrial transportation is a key strategy. This includes motorcycle taxis (moto-taxis), widely used in rural and peri-urban areas for short-distance passenger transport in Mexico. This study integrates environmental and social dimensions to evaluate moto-taxis in the Yucatán Peninsula, a region characterized by its unique energy matrix and socio-economic context. A cradle-to-grave Life Cycle Assessment (LCA), performed using SimaPro software and aligned with ISO 14040/14044 standards, compared gasoline-powered moto-taxis (M-gasoline) with electric moto-taxis using lead-acid (M‑lead) and lithium-ion (M‑lithium) batteries. The use-phase results reveal that M‑lithium has the lowest environmental impacts, followed by M‑lead and M-gasoline. Endpoint analysis further indicates that M-gasoline exhibits the highest single-score impacts in all damage categories, including human health, ecosystems, and resource scarcity. Specifically, the ecosystem damage caused by M-gasoline is more than three times that of its electric counterparts. Midpoint analysis highlights that M‑lead shows the highest impacts in freshwater and marine ecotoxicity, while M‑lithium exhibits elevated impacts in marine eutrophication, terrestrial ecotoxicity, and resource scarcity due to fossil fuel-based electricity. Social challenges such as driver safety, lack of social security, gender inequality, and limited financial support further influence the adoption of electric moto-taxis. Addressing these requires regulatory improvements, targeted subsidies, and inclusive urban planning. These findings underscore the need to enhance battery technology, transition to renewable energy, and implement socio-political solutions to advance sustainable urban mobility in developing regions. By contextualizing the study within Yucatán, this research offers insights applicable to similar regions transitioning to electric mobility.

Access to electricity in Zambia remains low, with most households dependent on traditional energy sources. This study analyzes data from a contingent valuation (CV) survey conducted by the World Bank to estimate household willingness to pay (WTP) for electricity connections among non-connected households. It evaluates two electrification technologies: grid electricity and solar home systems (SHS), categorized into low-capacity and high-capacity systems. The findings show that WTP is positive across technologies and increases with extended payment options. Mean WTP for grid electricity and high-capacity SHS exceeds market prices, indicating potential for private sector involvement in expanding access. In contrast, low-capacity SHS has a mean WTP below market prices, suggesting that subsidies are needed for viable private sector participation. This highlights the importance of offering electricity technologies that provide more than just lighting, particularly in rural areas where high-capacity systems can foster economic activities. The study also emphasizes the necessity for households to access credit financing or subsidies to afford market prices for solar PV systems and to manage their consumption effectively. Additionally, social factors such as housing quality and educational attainment significantly influence mean WTP for electricity connections across the various technologies.

Despite the introduction of clean energy technologies in sub-Saharan Africa (SSA), adoption has been slow as some households continue to rely on polluting fuels. This hinders the global energy sector's net-zero emission goal, particularly given that SSA constitutes a substantial proportion of the global population. This paper examines households' understanding of environmental issues and energy transition, with a particular focus on their role in the adoption of clean energy solutions. It further investigates households' expectations regarding the impact of a clean energy transition on their wellbeing.
Drawing on primary data collected from the Kwahu Afram Plains North and South Districts of the Eastern Region of Ghana, the findings revealed that 34 % of households did not associate energy sources with the environment and hence, disagreed that energy sources could affect the environment. Additionally, the study found that, despite its numerous benefits, a transition to clean energy solutions could adversely impact households. Some households indicated that this transition can potentially lead to a reduction in gross and discretionary incomes (40 %) and increase exposure to dangers (4 %). Furthermore, the findings showed that the livelihoods of nearly half of households (49 %) are tied to the production and sale of charcoal.
These findings underscore the need for a more sustainable energy transition that considers the potential impacts on rural households and actively involves households in the process. Consequently, this paper provides valuable insights for charting future directions to attain transition objectives, aligned with the Sustainable Development Goals and the African Union's Agenda 2063.

The global energy sector is undergoing a transition towards sustainable sources, with hydrogen emerging as a promising alternative due to its high energy content and clean-burning properties. The integration of hydrogen into the energy landscape represents a significant advancement towards a cleaner, greener future. This paper introduces an innovative decision support system (DSS) that combines multi-criteria decision-making (MCDM) and decision tree methodologies to optimize hydrogen production decisions in emerging economies, using Saudi Arabia as a case study. The proposed DSS, developed using MATLAB Web App Designer tools, evaluates various scenarios related to demand and supply, cost and profit margins, policy implications, and environmental impacts, with the goal of balancing economic viability and ecological responsibility. The study's findings highlight the potential of this DSS to guide policymakers and industry stakeholders in making informed, scalable, and flexible hydrogen production decisions that align with sustainable development goals. The novel DSS framework integrates two key influencing factors technical and logistical by considering components such as data management, modeling, analysis, and decision-making. The analysis component employs statistical and economic methods to model and assess the costs and benefits of eleven strategic scenarios, while the decision-making component uses these results to determine the most effective strategies for implementing hydrogen production to minimize risks and uncertainties.

The energy sector is pivotal in driving the transition towards a sustainable net-zero future, with the adoption of digital technologies playing a key role in this evolution. While much of the existing research has centered on sustainability through centralized energy generation and large-scale transmission systems, this paper addresses a notable gap by focusing on how data-driven decisions in local power systems, supported by digitalization, can enhance efficiency, reliability, and sustainability. The framework of this paper is derived from a survey from eight organizations of power sector, covering transmission and distribution, aiming to answer the question: “Which decisions within local power systems need to be informed by data?”. Through inductive coding of survey responses, we identified key themes fall into two main categories: requirements of local energy systems and opportunities provided by digitalization to meet these requirements. Mapping responses to each of these categories underscore the equal significance stakeholders place on the role of digitalization in both planning and operation. Also, with this mapping, we uncovered four key opportunities of digitalization, with predictability and interoperability being the most crucial, followed by responsiveness and automation. Aligned with the identified codes, academic research, industrial implementations and ongoing projects are reviewed to showcase the current practical applications of digitalization. Finally, we identify potential research areas that could further benefit local energy systems through effective use of digitalization. This paper provides insights into the digitalization opportunities in local power systems, offering a comprehensive overview for the data science and power engineering communities.

This paper presents a methodology for evaluating and identifying potential areas for the installa- tion of solar and wind power plants, including consideration of social aspects. The methodology is based on Geographic Information Systems (GIS) and maps derived from open data provided by various institutions. Multi-criteria analysis is used, which considers environmental and physical conditions, as well as social indicators and the specific cultural and economic characteristics of the area under analysis. The objective of this is to explore the intersection of potential power plant locations with social maps that represent different problematics that can be critical to the successful implementation of a generation project in a given area. The results indicate that solar energy is the most viable resource for electric generation in the Colombian territory. This can be equivalent to a total of 8.24T W · km2. In contrast, when considering the environmental impact, it becomes evident that viable zones begin to shift away from bodies of water and areas that are natural reserves. The results obtained are not only relevant for energy planning in Colombia, but may also be applicable in other contexts, contributing to the development of sustainable energy strategies at a global level. Furthermore, the methodology can serve as a model for other developing countries that seek to transition towards a more sustainable energy future.

Productive uses of energy – tied to the usage of energy for economically productive appliances – to catalyze improvements in livelihoods, healthcare, and education have gained increased attention recently from governments and donor organizations. Through an intensive qualitative field-study of 64 rural entrepreneurs in southern Indian state of Karnataka who adopted different types of Decentralized Renewable Energy Assisted Machines (DREAMs) to start or improve existing rural enterprises such as roti-making, blacksmithing, tailoring, and food-processing, we contribute toward understanding when, how, and for whom do such productive uses make a positive impact. Going beyond the analysis of financial returns, we present an integrated impact-resilience framework to analyze the non-financial and broader socio-economic impacts of improved electricity access for rural enterprises. We show that DREAMs activate a cascade of interlocking set of impacts and livelihood resilience measures. While there is a general appreciation that DREAMs may contribute to making the adopting households more resilient, we trace the pathways through which such resilience building might occur. The reorganizational effects of DREAMs on the economic and social fabric of rural life appear to be quite large and potent. Our observation of multi-faceted positive spillovers resulting from the adoption and use of DREAMs lends support for policy interventions to develop and support the local and regional ecosystems that undergird deployment of DREAMs in rural areas.
