This paper explores the implementation of the circular economy in the energy sector. The research findings contribute to our understanding of the practical application of the circular economy, enabling policymakers and stakeholders to make informed decisions and develop targeted strategies. The study analyzes 88 Portuguese companies’ reports, examining the presence of circular economy strategies and initiatives. The results reveal that energy sector companies tend to prioritize reporting their greenhouse gas reduction efforts over their circular economy strategies. The findings align with previous studies in the oil and gas industry, emphasizing the significance of sustainability reporting and potential biases in reporting practices. The study also identifies a gap between circular economy terminology and its representation in reports, indicating the need for greater incorporation of circular economy-oriented initiatives in the energy sector. The research highlights the role of technology in fostering innovation and calls for strategic alliances and knowledge sharing to drive circular economy practices. Further research is recommended to understand the barriers to implementing circular economy practices and identify effective solutions. Overall, this paper provides valuable insights for advancing the circular economy in the energy sector and achieving broader sustainability goals.

In light of new trends and realities, today's society promotes and values the importance of innovation and sustainability as a solution to the challenges ahead, where companies contribute to the attraction and retention of young talent through Telework. This study addresses Telework as a solution to new challenges. The focus of the study is five small and medium-sized companies. It was concluded that companies opted for Telework at home, with advantages of cost reduction, conciliation of personal and professional life, and reduction of pollutant gases; and as disadvantages, the investment in equipment, social isolation, and precariousness of the labor market. The impacts of telework were verified at the level of productivity, commitment, and performance, where it was concluded that telework can be partially maintained. The contribution of this work focuses on the importance that virtual experiences have in Generation Z and the flexibility of companies in adopting pre-existing work models.
