Ukraine, facing challenges from Russian attacks and a fossil-dependent energy system, is embarking on a transformative journey towards a greener and decentralized energy future. The country's goal to join the EU has prompted the implementation of a revised energy system focused on renewable sources and decentralization. Partners such as the EU and the US are actively involved in supporting Ukraine's energy sector restructuring to enhance energy security and pave the way for EU integration. The potential for Ukraine to serve as a model for decentralized electricity systems powered by renewables highlights the importance of this transition. To accelerate progress, a robust institutional and regulatory framework must be established, alongside efforts to attract investments in the sector. Furthermore, plans to repurpose existing gas infrastructure for green hydrogen production reinforce Ukraine's aspirations to export environmentally friendly energy to Europe. The proposed Green Agenda aims to steer policy reforms in the energy sector, ensuring alignment with EU standards and guiding Ukraine towards a sustainable energy future.
