Who are the invisible energy precarious groups? What needs to be done? What are the barriers to achieve ‘what needs to be done’? How can we overcome these barriers? In this context, the ENGAGER right to energy toolkit aims to assist scholars, civil society, policy-makers, students and media in engaging with energy poverty through the concept and language of the ‘right to energy’. It is a collaborative effort through which more than 25 ENGAGER researchers and practitioners are jointly reflecting on the principles and practice of the right to energy.
