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 (CO<sub>2</sub>) 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 CO<sub>2</sub> 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 CO<sub>2</sub> 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.

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. The findings of this paper helps to understand the existing status of surveyed process industries and comprehend the tapped potential toward energy optimization along with identification of untapped potential to be harnessed in future and emphasize the need to treat energy as strategically vital to business.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"83 ","pages":"Article 101579"},"PeriodicalIF":4.4,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142527301","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}

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.

By meticulously accounting for geographic and depth-related constraints, the study assesses the feasibility of implementing both fixed-bottom and floating wind energy technologies. Revealing an offshore wind capacity of 1,609.7 GW, capable of producing an estimated 12,688 TWh annually, our analysis highlights the capacity to exceed Mexico’s current energy consumption by thirty-three-fold. Significantly, it determines that 58% of the evaluated maritime area is suitable for floating technologies, while 42% could support fixed-bottom installations. Economic evaluations, including the Levelized Cost of Energy (LCOE) analysis, suggest a competitive price range of 63 to 241 USD/MWh, positioning offshore wind as a viable alternative to conventional and hydroelectric power sources. Although the study identifies considerable potential, it also exposes significant infrastructural challenges in Mexico’s electrical grid, which pose barriers to the effortless integration of offshore wind technology. The findings underscore the urgent need for infrastructural improvements and strategic policy modifications to maximize the use of Mexico’s plentiful offshore wind resources. Additionally, the research stresses the critical role of international cooperation, through North-South partnerships, in expediting the shift toward renewable energy sources.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"83 ","pages":"Article 101565"},"PeriodicalIF":4.4,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142427246","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}
