Focuses on establishing a dynamic, international learning community to foster knowledge exchange in the sustainable energy sector. Central to WP5 are efforts to streamline shared standards, approaches, and experiences across various regions. This endeavor includes hosting a European Conference on Regional Cooperation to underscore vocational excellence in Fossil Free Energy, fostering a collaborative environment for learning and innovation. The package also encompasses a series of actions: organizing workshops to outline and implement regional learning strategies and action plans, facilitating an international workshop for transnational learning strategies, and creating a framework for regional innovation and adaptation of SEED lessons learned. These actions aim to gather, review, and implement feedback for continuous improvement. Additionally, WP5 is dedicated to the long-term development of the SEED community, involving the expansion of partnership strategies, development of online content contribution mechanisms, and providing guidance for the sustainable growth of SEED initiatives. Through these comprehensive measures, WP5 aspires to bridge regional and international gaps, promoting a continuous exchange of innovative ideas and practices, crucial for advancing the fossil-sustainable energy landscape.
