This gap raises questions about the factors influencing individual attitudes towards renewable energy infrastructures. Drawing on the literature about the acceptance of renewable energy, we examine the impact of attitudes towards climate policy, populism and place attachment on the acceptance of renewable energy infrastructure. Additionally, we examine differences in acceptance between East and West Germany. Using instrumental variables (IV) regression and Blinder-Oaxaca decomposition with a representative survey sample of 8,643 individuals, our study shows that positive attitudes towards climate policy significantly increase the acceptance of renewable energy infrastructures in Germany. Conversely, populist attitudes are associated with lower levels of acceptance. While place attachment has no significant effect, acceptance is notably lower in East than in West Germany. These results provide insights into the complex reasons behind the acceptance or rejection of renewable energy projects and highlight the need for climate policies that are sensitive to regional and political nuances. Tailored communication strategies that take these differences into account are essential to foster acceptance and bridge the gap between general acceptance and local rejection. In conclusion, the successful advancement of the energy transition in Germany requires acknowledging and addressing the diverse socio-cultural contexts across the country.</div></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"7 ","pages":"Article 100232"},"PeriodicalIF":5.6,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146038106","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}

Through a systematic review of 43 peer-reviewed studies that follow the PRISMA protocol, results reveal that renewable energy can enhance agricultural productivity by reducing operational costs, increasing efficiency in irrigation and processing, and providing reliable access to energy. However, challenges exist, including competition for land and water resources between renewable energy projects and food production, high upfront costs of clean energy technologies, limited access to credit facilities, and institutional bottlenecks. To overcome these challenges, recommended policies include offering subsidies and financial incentives to make clean energy more affordable for farmers, as well as providing education and training to support the adoption of sustainable practices. Furthermore, promoting collaboration between the public and private sectors is crucial to stimulate investment in renewable energy infrastructure. Moreover, these policies must be designed for specific national circumstances. High-income or upper-middle-income countries can deploy capital-intensive agrivoltaic and biogas technologies via concessional finance. In contrast, low-income settings should prioritize low-cost, decentralized solar pumps and off-grid dryers to build farmer confidence and trust. Countries with stronger regulatory frameworks and secure land tenure systems are better equipped to support large-scale renewable energy projects. At the same time, regions with weaker governance tend to benefit most from community-owned mini-grids. The mapping of policy options onto economic, institutional, and agro-ecological dimensions provides a nuanced, context-sensitive framework to guide equitable and effective energy transitions in diverse agricultural landscapes.</div></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"6 ","pages":"Article 100222"},"PeriodicalIF":5.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145519421","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}

Previous model comparison studies in Japan did not adequately address uncertainties from technological development under the latest net-zero commitment, potentially hindering effective stakeholder decision-making. This study coordinates multiple integrated assessment and energy systems models to analyze consistent policy and technology scenarios, focusing on energy transition pathways in end-use sectors. The results show that, to meet the net-zero requirement, all models exhibit a similar trend of declining total final energy demand, with a reduction of approximately 30% by 2050 relative to 2020. Meanwhile, electricity may account for around 50% or more of the total final energy in 2050 while hydrogen could grow to approximately 13%, with growth accelerating after 2040. Hydrogen is effective in achieving deep reductions in industrial emissions, and its necessity increases as emission targets become more stringent. The government has set ambitious targets for the utilization of hydrogen, but its deployment in end-use sectors requires further policy guidance to facilitate investment.

Specifically, the proposed modeling approach takes into account the reduction of empty trips, the optimization of cargo consolidation, and the promotion of eco-driving practices based on national freight transport data (i.e. covering more than 7.99 million trips). The proposed approach examines the effect of introducing contemporary vehicle technologies, such as new diesel vehicles (EURO VI or higher), new natural gas vehicles (EURO VI or higher), electric vehicles and hydrogen vehicles, as feasible replacements for aging vehicles powered by conventional fossil fuels. The adoption of these cleaner and newer technologies demonstrates the potential for emission reductions of up to 13% (2,070,000 tons CO₂e) by 2030 and 47% (13,232,000 tons CO₂e) by 2050.

This paper summarizes the potential contribution of bioenergy use in the electric power, transportation, industrial, and buildings sectors toward meeting that target based on model results. Thirteen modeling teams reported bioenergy consumption in the Reference and Net Zero scenarios. Consumption of bioenergy increased over time in the Reference scenario, from an average across models of 3.2 exajoules (EJ) in 2020 to 3.8 EJ in 2050. Average bioenergy consumption in 2050 increased further to 7.3 EJ in the Net Zero scenario. All scenarios that reach net-zero emissions required some form of carbon dioxide removal to offset emissions that are difficult to reduce. Carbon dioxide removal using bioenergy with CO₂ capture and storage (BECCS) varies widely across models, up to 1000 Mt CO₂ in 2050. Some models rely instead on direct air carbon capture and storage (DACCS), up to 2200 Mt CO₂, and others use a combination of BECCS and DACCS. Model results show a strong inverse relationship between the amounts of BECCS and DACCS deployed. All modeling teams assumed a carbon sink from land use, land use change, and forestry, further offsetting a portion of emissions from fossil fuels and industry that are expensive to eliminate. Bioenergy consumption in 2050 decreased by an average of 1.5 EJ across eight models in a Net Zero+ scenario relative to the Net Zero scenario, due in part to a lower equilibrium carbon price resulting from optimistic cost assumptions for all energy technologies.</div></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"6 ","pages":"Article 100209"},"PeriodicalIF":5.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723071","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}

This study aims to assess potential decarbonization pathways for the industrial sector and their impact on production costs. A bottom-up optimization approach, using the TIMES model, was employed to determine optimal technology pathways by minimizing production costs while achieving the targeted CO₂e emission intensity for each industry. The results indicate that an ambitious Net Zero Emission (NZE) scenario will reduce emissions from 466 MtCO₂e to 56 MtCO₂e by 2060.
