<p>Renewable energy technologies, e.g., solar photovoltaics, electric vehicles and wind turbines, are instrumental in producing renewable energy and promoting environmental safety. We examined how these technologies enhance environmental safety, considering regulatory governance and public awareness from the perspectives of residents in the Hail Region of Saudi Arabia. We administered a questionnaire survey using a purposive sampling technique with 275 respondents and analyzed the data using a PLS-SEM approach. Wind energy technology significantly improved environmental safety, moderated by regulatory governance and public awareness. In contrast, the roles of solar energy and electric vehicle technologies in environmental safety were found to be ineffective, even when moderated by both regulatory governance and public awareness. While the age of respondents emerged as a relevant factor, gender, occupation and education level did not significantly impact the improvement of environmental health. We conclude that advocating for the establishment of robust regulatory governance can enhance the functionality of solar and electric vehicle technologies and contribute to the environmental safety of Hail, Saudi Arabia.</p>
