The decarbonisation of the energy system requires that all European citizens can make full use of renewable energies. However, there is a high percentage of citizens with many difficulties to have renewable energy facilities and equipment, in particular the vulnerable groups, including those affected by "energy poverty". These difficulties are motivated by economic and technological issues (renewable energy solutions are not adapted to vulnerable groups), but also by other factors of a social and cultural type, use and owners of housing, etc., which influence the types of solutions that should be used, as well as how to manage them. The general objective of the project is to increase the use of renewable energies in vulnerable groups. This way, thanks to the project, new renewable energy installations will be facilitated to provide safe and clean energy to vulnerable households. In addition, companies supplying renewable energies will be encouraged through the project to offer technological solutions that are adapted to vulnerable groups, activating their corporate social responsibility. In this way, POWERTY will help to tackle energy poverty, promoting vulnerable households with adequate energy supplies, thanks to renewable energies. Given the exceptional conditions of these households, social innovation measures will be promoted, based on greater participation, integration and empowerment of vulnerable groups. The project will develop a complete learning process to facilitate an effective knowledge flow among regions, counting on 6 partners with different complementary expertise and different levels of competences (regional/national) which enriches the transfer of knowledge. More than 50 best practices and almost 50 events involving 60 stakeholders will establish 5 Regional Action Plans covering a population of more than 25 million inhabitants .
