Offshore wind energy is widely regarded as one of the most credible sources for increasing renewable energy production towards a resilient and decarbonized energy supply. However, current expectations for the expansion of energy production from offshore wind may lead to significant environmental impacts. Assessing ecological risks to marine ecosystems from electricity production from wind is both timely and vital. It will support the adoption of management measures that minimize impacts and the environmental sustainability of the offshore wind energy sector.In this study, the review of literature analyzed the external effects of wind turbines, which are often considered detrimental to the promotion of wind power generation. Understanding these externalities is essential to reaching a consensus with residents who live near the site of a planned wind turbine. Our research objective was to determine the relationship between wind turbines and people's well-being in areas where they have been installed for a long time. They hypothesized that wind turbines would have a negative impact on people's well-being. Also conducted a survey by postal mail in Chōshi City, Chiba Prefecture, Japan, to examine the external effects of wind turbines, adopting a subjective well-being index to measure respondents' well-being. Regression analysis suggests that having a view of wind power turbines has a positive effect on the subjective well-being of residents. Moreover, the results indicate that such well-being increases with increasing distance from the turbines. Except for scenic elements and found that wind turbines are not always considered desirable by residents. Therefore, it is important to further clarify the external influence of wind turbines and other facilities in local communities
