While the environmental benefits of the transition to low-carbon energy supply systems have been widely discussed, economic effects have only been touched upon in a piecemeal fashion, e.g. through employment in the renewable energy sector, the increasing cost competitiveness of energy from renewable sources, or the rise of energy poverty. In particular, it remains unclear how the economies of Europe's diverse regions are affected by the shift to decentralised, low-carbon energy supply. As recent political initiatives in relation to coal regions and islands however show, Europe's energy transition has a distinctively regional dimension. The EESC is currently working on an own-initiative opinion on "The effects of a new carbon-free, decentralised and digitalized energy supply structure on jobs and regional economies". In this opinion, it seeks to take stock of existing economic analyses on the regional effects and develop an assessment framework. To this end, it invites representatives from the regions, civil society, and experts from the EU institutions and beyond to discuss new approaches to regional development propelled by regional energy transition in the context of a public hearing.
