This paper presents a comprehensive framework for understanding public acceptance of sustainable energy technologies, based on psychological theories and empirical studies. It identifies key psychological factors influencing acceptance, including attitude, social norms, perceived behavioral control, and personal norm. The framework suggests that attitudes are shaped by perceived costs, risks, and benefits, positive and negative feelings towards the technology, trust, and fairness. Personal norm is influenced by perceived costs, risks, benefits, outcome efficacy, and awareness of adverse consequences of not accepting the technology. The framework also considers the effects of perceived context, such as trust and fairness, and the role of knowledge and experience in shaping acceptance. The study concludes that the framework can be used to improve the design and communication of sustainable energy technologies, and to enhance their acceptance and implementation. The framework is applicable to various sustainable energy technologies, including wind power, carbon capture and storage, and hydrogen technology. The paper emphasizes the importance of understanding the psychological factors that influence acceptance, and highlights the need for further research to clarify the causal relationships between these factors.This paper presents a comprehensive framework for understanding public acceptance of sustainable energy technologies, based on psychological theories and empirical studies.
