Although Latin America contributed relatively little to global energy-related CO<sub>2</sub> emissions and maintains a predominantly renewable electricity mix, it remains the largest emitter in the world from land use change and forestry sectors. The region's continued dependence on fossil fuels, particularly in high-emission sectors such as transport, as well as, its reliance on oil revenues and extractive industries presents significant structural barriers. Weak, often non-binding, climate governance frameworks further undermine progress. While national commitments increasingly emphasize renewable energy deployment, achieving a meaningful transition requires systemic reforms, stronger institutional enforcement, and improved policy coherence.

The findings reveal that sugarcane, maize, and rice-based ethanol provide the most significant ecological benefits, with net CO<sub>2</sub> emissions of −1.61 kg/L, −0.19 kg/L, and 0.81 kg/L, primarily due to their superior carbon sequestration potential and installation of carbon storage plants in the distilleries, making them environmentally preferable to petrol. Additionally, ethanol demonstrates better combustion properties and a lower carbon intensity compared to petrol, thereby reinforcing its role as a cleaner alternative for energy. The study further highlights that integrating CO<sub>2</sub> capture technologies in ethanol distilleries can significantly reduce emissions, thereby enhancing both environmental sustainability and economic feasibility.

Consumer preferences and infrastructure availability are critical to BEV diffusion, especially for electric motorcycles. In addition, total motorcycle stocks are projected to decline after 2036 due to the potential mode shift to passenger cars as socioeconomic conditions improve.

Data is collected through an online survey conducted in five major cities in Indonesia. This study adapts the features of the double-bounded Contingent Valuation Method (CVM) to elicit preferences.

Why these non-positive results occurred are not explained in many of the primary studies, showing a need for more research. When the non-positive findings are analysed, the most common preventative barriers related to electricity supply quantity and quality, and service affordability. Barriers caused by a disconnect between what people value compared to what is being provided were also common. This work contributes insights into the importance of understanding how individual and community values influence the structural provision of electricity access.

The paper seeks to unpack empirically the evidence that counters the misconceptions around e-cooking among urban and peri-urban households in the Greater Accra Region and to assess their willingness to use and pay for e-cooking technologies. Two methodological approaches were employed to achieve these objectives. Firstly, standardized semi-controlled cooking tests were carried out with four local meals prepared using 4 fuel technologies. Secondly, a mixed method (quantitative and qualitative) approach was utilised, involving the survey of 1203 households from Adenta, Ga East, and Ga West Municipalities. The results revealed that at least 70 % of the households sampled perceived e-cooking to be more expensive than cooking with charcoal and LPG. However, the cooking experiment outcomes showed e-cooking to be far cheaper compared to cooking with charcoal and LPG. Households' willingness to use e-cooking technologies increased after they saw the results of the experiment. However, most of them demonstrated a lower willingness to pay values than the market value of the Electric Pressure Cooker due to lack of affordability.

The model is built with manually gathered country-specific data, made available in open-source, and validated against official national statistics. The model is then applied to Nigeria and South Africa to evaluate the impact of national transmission expansion and pumped hydro energy storage (PHES) on variable renewable energy (VRE) penetration. Our results highlight that strategic combinations of storage and grid enhancements can significantly increase renewable utilization, reduce curtailment, and lower emissions. While PHES is particularly effective in solar-dominated contexts, transmission expansion plays a crucial role in overcoming regional grid constraints, as observed in South Africa. The findings emphasize the importance of country-specific strategies for VRE integration and reinforce the role of infrastructure planning in achieving Sustainable Development Goal 7 (SDG7), particularly Target 7.2 on increasing the share of renewables, and how this can potentially have beneficial indirect effects on Target 7.1, universal access, and 7.3, increased efficiency. This work introduces a novel application of the Calliope framework tailored to African countries, combining high-resolution national models with a flexible scenario-based methodology to quantify the role of PHES and grid expansion. Unlike existing studies, it leverages open-access, validated data and focuses on less-explored storage options such as PHES rather than BESS, thus filling a methodological and thematic gap in the current literature. By demonstrating how different approaches shape renewable integration outcomes, this study provides a replicable methodology for policymakers and energy planners seeking cost-effective, resilient pathways towards decarbonization.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"88 ","pages":"Article 101760"},"PeriodicalIF":4.4,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271968","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}
