Summary: Wind energy plays a crucial role in the energy transition, but local conflicts often arise in wind energy projects. Mayors and local council members are important actors in deciding the siting of wind energy projects. This study explores the experiences of four Bavarian case studies in Germany, revealing that mayors have a significant impact on local responses, but their support alone is insufficient for local acceptance. The findings have implications for policymakers and practitioners in terms of communication and information strategies in wind energy project design and planning.

Summary: Decision makers often worry about the potential impacts of offshore wind development on coastal tourism, but little research has studied tourists' attitudes towards an offshore wind project over time. This study used an intercept survey to collect viewpoints of visitors to Block Island, USA, before, during, and after the construction of a nearshore, five-turbine development. The results show that tourists' acceptance of the project increased over time, and there was a positive correlation between acceptance and having seen the construction activities or the completed project. Regression and path analyses support the values-beliefs-norms theory, with underlying values and beliefs explaining a significant portion of tourists' acceptance.

Summary: This study provides a baseline for longitudinal studies on public acceptance of offshore wind farms along the US East Coast. Using a visual-only discrete choice design, the preferences of US East Coast residents for offshore wind farms are evaluated. Factors such as distance from shore, project size, turbine size, and the presence of birds in the images are examined for their impact on viewers' perception and willingness to accept potential projects. The results show that distance from shore is the most important factor for social acceptance, followed by project size, while turbine size has an insignificant effect. The study highlights the need to focus on public attitudes towards the visual impacts of proposed projects, particularly the distance from shore, in order to achieve the goal of reaching 30 GW by 2030.

Summary: This article examines the acceptance of wind power in Sweden by municipal decision-makers through semistructured interviews, document analysis, and statistical data. The findings suggest that wind power opposition is not solely a NIMBY effect, but also influenced by the attitudes of local residents and perceptions of distributional injustice. Furthermore, the acceptance of wind power by municipalities is influenced by national politics, economic factors, institutional settings, regulations, and sociopolitical factors. To overcome acceptance barriers, the article suggests the implementation of formal compensation schemes for local communities and municipalities, and allowing municipalities to levy taxes on wind power to address energy injustice and accommodate different interests.

Summary: Local community acceptance plays a crucial role in wind farm siting decisions but existing studies on social acceptance do not consider how perceptions of the local community may change over the operational life of a wind farm. This paper presents survey results from two English wind farms that have experienced end-of-life applications, increasing our understanding of social acceptance over time. The findings reveal that community support for repowering or life-extension applications is influenced by the experiences of living with the wind farm, and factors such as benefits, involvement in the planning process, and relationships with the developer can impact responses to end-of-life applications. These insights provide recommendations for end-of-life policy.

Summary: As the demand for a fair and equitable energy transition grows, disruptive clean energy technologies are becoming more visible to the public. However, the rapid deployment of these technologies poses various technical and non-technical challenges, such as grid integration, public opposition, and competition for land use. In this article, a reinforcement learning-based methodology is proposed to minimize contention risks and maximize renewable energy production during siting decisions. The methodology is tested on a case study of wind turbine siting in Illinois, showing significant reduction in potential delays compared to random decision-making. This approach has the potential to be applied to other clean energy technologies as well.

Summary: The number of studies on social acceptance of wind energy in the United States and Canada has greatly increased since the 1980s. This review of literature on wind acceptance research (WAR) examines the location of study sites, the success of different study designs and incentives, the dominant disciplines and theories, and dissemination practices. The findings suggest that most studies focus on controversial or unique projects in regions distant from areas with high installed wind capacity. The review also highlights the lack of underlying theories in most WAR studies and recommends greater integration of existing theories and research methods, as well as consideration of the broader community contexts.

Summary: The research aims to study and evaluate the conflicts caused by the rapid increase in wind parks, in order to find ways to carry out such projects in conditions of cooperation, mutual interest and profit. Data was collected through a survey with approximately 600 responses and analyzed using SPSS. The results show that the NIMBY effect does not significantly influence the acceptance of the project, and the acceptance is independent of income. The main determinants of the public attitude are continuous briefing and reduction of greenhouse gas emissions, as well as the impact on flora and fauna and the lack of trust in investors.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.
