A fundamental transformation of the energy system is urgently needed to address this issue. To gain a better understanding of how exposure to extreme weather events and perceptions of climate change influence support for expanding renewable energies, a nationally representative survey was conducted in 2021, incorporating contextual data on the cost of billion-dollar disasters and carbon dependency. The study's findings suggest that extreme weather events influence the public's perception of climate change, especially among Republicans. Age also plays a role, with younger people more likely to prioritize climate change. Public support for renewable energies is influenced by the perception of climate change as a priority issue, and carbon dependency decreases support for renewable energies. Policymakers should focus on highlighting the link between extreme weather events and climate change, target younger generations with messages about climate change, and consider alternative approaches to supporting carbon-dependent regions. The study has some limitations, including that it is based on cross-sectional data which may not account for potential endogeneity. Additionally, there are no contextual variables at a geographic level finer than the state, and future research should consider adopting measures at finer scales such as county and zip code. The study's theoretical framework could be further validated by integrating observational climate extreme data into understanding individuals’ perception of local weather and climate, and future studies should adopt path analysis or structural equation modelling to validate the proposed path when all relevant variables are included.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"5 ","pages":"Article 100139"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141278109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study Sweden as a case of a country that is comparatively advanced in its planning for transitions to low-carbon industrial production. We find that the size of capital investments or the availability of financing for these investments is not perceived as a significant obstacle. There are a number of factors explaining this, such as the fact that the companies involved in this study are well-established, large corporates, and hence well placed to finance their transition plans through conventional corporate finance channels, that conditions for market demand are good in the EU, and that many of the firms are in early stages of developing new technologies, when capital need is smaller compared to later stages. We also find that many financial actors express a strong appetite for sustainable investments. Finally, we observe that despite financing not being perceived as an obstacle, there is still a large and important role to play for public actors for reducing the risk of investments and accelerating the pace of change going forward.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"5 ","pages":"Article 100138"},"PeriodicalIF":0.0,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141325217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solar water heating system (SWHS) is one of the most adopted technologies all over the world. Moreover, the building sector consumes significant energy from fossil fuels worldwide to meet hot water demand. This fossil fuel consumption can be reduced with the surplus economic and environmental benefits through the refurbishment of SWHSs in residential buildings. Additionally, the student hostels of academic institutes/Universities have great potential to save energy, environment, and money. In view of the same, the technical, economic, and environmental analyses of refurbishing SWHS in the student hostel are presented in the present paper. The analysis is carried out for the hostel named ‘Raman’ of DIT University, located in Dehradun, India. The energy-saving potentials of flat plate collector (FPC)-based and evacuated tube collector (ETC)-based SWHSs to accomplish the hot water demand of selected site are assessed in comparison with electric geyser. Moreover, the economic analysis is also reported in terms of net present value and benefit-to-cost analysis. Whereas the environmental benefit is presented in terms of reduction in equivalent CO<sub>2</sub> emissions through implementing both types of considered SWHSs. It is found that the FPC-based and ETC-based SWHSs can fulfil 60.9 % and 67.6 % of the energy demand to heat the required water. Whereas, both of the systems are found economically as well as environmentally beneficial and ETC-based SWHS is recommended for the selected site. The present study may be useful for the energy planning and management of student hostels under academic institutes/Universities.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"5 ","pages":"Article 100137"},"PeriodicalIF":0.0,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140906080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our analysis was conducted using an ARDL panel data model with data from 26 countries representing four sub-regions. The results demonstrated that an increase in renewable energy consumption is significantly associated with a decrease in GHG emissions, with a long-term coefficient of -0.422 and a short-term coefficient of -0.757. Additionally, natural resource rents, agricultural land use and population density have a positive impact on greenhouse gas emissions, with coefficients of 0.0605, 0.392 and 0.690, respectively. However, renewable energy production does not have a significant effect on greenhouse gas emissions. This suggests that promoting renewable energy consumption can be an effective way to combat greenhouse gas emissions in the region, and policymakers should implement policies and programs that encourage and facilitate the adoption of renewable energy whilst taking into consideration the impact of agricultural land use. Overall, this study emphasizes the importance of promoting renewable energy consumption and managing agricultural land use as a viable approach to combating greenhouse gas emissions in sub-Saharan Africa, and highlights the potential of climate mitigation technology as a tool for regulators to optimize policy development and counter climate change.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"5 ","pages":"Article 100135"},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140791261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, large-scale deployment of green hydrogen has associated potential trade-offs in terms of climate and other environmental impacts. This study aims to shed light on a comprehensive sustainability assessment of this large-scale green hydrogen deployment based on the EMPIRE energy system modeling, compared with other decarbonization paths. Process-based Life Cycle Assessment (LCA) is applied and connected with the output of the energy system model, revealing 45% extra climate impact caused by the dedicated 50% extra renewable infrastructure to deliver green hydrogen for the demand in the sectors of industry and transport in Europe towards 2050. Whereas, the analysis shows that green hydrogen eventually wins on the climate impact within four designed scenarios (with green hydrogen, with blue hydrogen, without green hydrogen, and baseline), mainly compensated by its clean usage and renewable electricity supply. On the other hand, green hydrogen has a lower performance in other environmental impacts including human toxicity, ecotoxicity, mineral use, land use, and water depletion. Furthermore, a monetary valuation of Life Cycle Impact (LCI) is estimated to aggregate 13 categories of environmental impacts between different technologies. Results indicate that the total monetized LCI cost of green hydrogen production is relatively lower than that of blue hydrogen. In overview, a large-scale green hydrogen deployment potentially shifts the environmental pressure from climate and fossil resource use to human health, mineral resource use, and ecosystem damage due to its higher material consumption of the infrastructure.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"5 ","pages":"Article 100133"},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666278724000096/pdfft?md5=d596eea3f8715806ea95d3047f59de72&pid=1-s2.0-S2666278724000096-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140755978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The indicator rests on the latest definition of the IPCC, which treats risk as the combination of <em>Hazard, Exposure and Vulnerability</em>. In our risk index, Hazard is described as the drop in production of fossil fuel-related sectors due to the transition risk, Exposure is the respective employment share, while Vulnerability is a composite index of socioeconomic sub-indicators that further describe <em>Sensitivity</em> and <em>Adaptive Capacity</em> of the regions. We find a wide divergence across the risk profiles of EU regions. 6 % of all EU regions are found to be at high risk, while 74 % of the regions face no risk.
