Research and Innovation (R&I) is crucial for advancing renewable energy development and efficiency within the energy sector.However, the workforce in energy R&I remains predominantly male, influenced by two key dimensions of inequality: the gendered flow of specialized Science, Technology, Engineering, and Mathematics (STEM) students and a work environment that fails to support women's participation. This report presents data and analysis from the gEneSys survey, which targeted researchers, technicians, experts, academics, and practitioners engaged in scientific and technological knowledge production for the energy sector in 25 EU countries. The survey aimed to assess job satisfaction, organizational culture, work-related qualityof life, and collaboration dynamics, with a particular focus on persistent gender inequalities in the energy R&I workforce and potential strategies to address these issues from the workers' perspective. The cluster analysis highlights a pronouncedprecariousness among women in R&I linked to greater challenges in achieving professional advancement, formal recognition, and respect in the workplace. Furthermore, women respondents demonstrate a heightened and clearer perception of gender inequalities, emphasizing the interplay between gender, job insecurity, professional roles, and both overt and covert discrimination in the work environment.
