EMPOWER 2.0 is an Interreg North Sea Region project aiming to empower citizens to become active energy citizens. To assist citizens, authorities and energy communities in producing their own green energy, the project created an online toolbox with resources relevant to that purpose. The toolbox is a collection of guides, projects, example cases and tools, including calculators, apps, and other platforms, either of local interest for countries participating in the project, or general for Europe. The user can browse these resources while filtering by theme, location or type of tool, or depending on the type of problem they want to solve. The approach provides resources to address technical, legal and economic challenges, as well as building up the community.
