Despite global efforts to achieve sustainable development goals (SDGs), many energy projects have failed due to technical and institutional problems and misunderstandings. Failure leads to uncertainty at the end of long-term transformative change, but discussion of failure in socio-technical transitions has been limited as the current body of knowledge focuses primarily on highlighting ‘winning’ innovations and their historical path. Exploring project failure can potentially reveal the misalignments in socio-technological configurations that lead to stagnation in progression of transition trajectories. Failures have discursive implications as they can result in a period of instability and so trigger actors to revisit their commitment towards transition visions and effectiveness of trajectories. This article contributes to debates around project failures by tracing their impact on overarching ideas of transition. The case of Sumba Iconic Island (SII), as one of the strategic efforts of Indonesia's energy transition, is selected for an in-depth exploration. Our analysis found that the ideational power of SII, which is embedded in the overarching discourse of Indonesia's energy transition, is relatively stable despite numerous technical and managerial failures. However, people's trust in renewable energy ambition has been diminished as centralised diesel-generated electricity offers better reliability.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552284","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}

Xinghualing District, Taiyuan City, Shanxi Province, China was selected for the case study. The constructed combination analysis method supports the key phases of the assessment process, including land classification, PV available area calculation and PV technology optimization deployment. The solar radiation receiving capacity of the plots is calculated by using the parameterization method, and a weighting on the four PV criteria of power generation capacity, economic cost, environmental impact and aesthetics is calculated by using the analytic hierarchy process (AHP). The best PV deployment scheme is determined by TOPSIS. The evaluation results show that the PV potential of Xinghualing District is 2790.5GWh per year, and the plot type with the highest power generation potential is multi-storey residential, which reaches 635.9GWh per year. The PV potential of the high-rise buildings lies more in their facade. The area with the highest PV potential in the region is located in the southwest, with dense buildings and of complex function. The proposed method in the case study takes into account the different requirements of different plots and building skins for the PV deployment, which improves the accuracy of the assessment.

The results show that charging infrastructure availability and cost concerns (resale anxiety and high upfront vehicle cost) are the major barriers to EV adoption. The findings identify subsidies for charging points, along with the establishment of battery and charging standards, and battery swapping services, as the most effective policies for mitigating the barrier of charging infrastructure availability.

However, it remains unclear whether HSR can meet carbon peak goals on time, under the high uncertainty of future electricity development. This study integrates scenario analysis and Monte Carlo simulation into life cycle assessment, proposing a probabilistic framework for dynamically simulating the carbon dioxide (CO₂) emissions over the entire life cycle of HSR. Monte Carlo simulation-Latin hypercube sampling method is introduced to model the uncertainty in the development of electricity. The results show that with the gradual increase in the proportion of clean electricity, the time when the CO₂ emission intensity of HSR is lower than that of electric cars and electric coaches is most probable to occur in the 2nd–3rd years and the 5th–14th years of operation, respectively. The emission trend of HSR is primarily influenced by the passenger growth rate and the depth of transition to clean electricity, with minimal impact from the loading factor and initial passenger volume. When the passenger growth rate reaches 5 % by 2030, transitioning solely to clean electricity can peak CO₂ emissions from HSR by 2030. However, with passenger growth rates of 6 %, 7 %, 8 %, and 9 %, the peak time is most probable to be delayed by 6–7 years, 13–14 years, 16 years, and 19 years, respectively.

Some industries in India are proactively leveraging their available resources and cost-effective measures to optimize their energy systems for sustainable industrial development. However, numerous process industries, grappling with limited resources and intense competition, encounter heightened challenges on the path to energy optimization. This paper focuses on the development of a conceptual framework to assess the energy optimization potential of process industries in India, focusing on their energy management policies and processes, and the realization of benefits from energy optimization, after analyzing gaps from an exhaustive literature review. Further the framework helped in development of Energy Management Maturity Matrix (EMMM) for the process industries in India, which is used as a tool to analyze and assess the energy optimizing potential based on the current energy systems of process industries. The primary data was collected using an exploratory survey conducted among process industries through in-depth interviews using structured questionnaire, which provided insightful findings, enriching our understanding of current energy practices in process industries and the energy conservation measures they employ which are discussed in the paper. The responses of the survey were analyzed and mapped with the EMMM that segregates the firms based on the obtained scores. The energy optimization potential of the firms were also calculated indicating the capacity for improvement within the company's energy management systems.

As the world's population grows and living standards rise, building energy use rises. Climate change is expected to impact interior environments, leading to uncertainty in analyzing energy and thermal usage of existing structures. Among the effects of climate change is a temperature increase that affects the indoor climate. Understanding future climate scenarios and their impacts can enhance the adaptability of existing buildings. The article extensively analyzed how climate change affects the energy usage of housing developments to address this problem. This study aims to determine the thermal behavior of existing buildings in Jordan in present and future timeframes, considering the effect of different orientation scenarios. Using Design Builder software, a family's home in a Hot Semi-Arid Climate zone presented by Amman City is modeled, and its internal circumstances are documented for the current climate and the next 40–70 years' predictions. Larger homes will see higher fluctuations in their energy load than smaller homes. Based on Köppen climate classification of the present and future times, the findings indicate that by 2100, mechanical cooling will be needed most of the time. Even with suggested tactics, the structure will not be pleasant without conditioning. The research indicates that the climate zones in Amman city are expected to shift from their current classification to arid zones with two distinct thermal regions, according to the climate maps provided. This transition is predicted to increase cooling loads significantly, rising from 2544.90 kWh/year to 4076.34 kWh/year, while heating loads are predicted to decrease from 4197.56 kWh/year to 3719.15 kWh/year.
