"This powerful and important book confirms the depth of energy poverty in post-communist Europe, with ten, detailed, country chapters. It provides an accolade to the European COST programme - and the ENGAGER project in particular – as it shows the real benefits that come from sharing knowledge and then learning from it. This, the first comprehensive review of energy poverty in post-communist Europe, will help to ensure that future policy is based on a clearer understanding - if the policy-makers want to listen. And, where politicians continue to evade the issues, we, the academics, activists and the concerned, will have a stronger basis for holding them to account. It is strongly recommended." -- Brenda Boardman, Emeritus Fellow, Environmental Change Institute, University of Oxford, UKThis work was supported by a grant of the Romanian Ministry of Education and Research, CNCS/CCCDI-UEFISCDI, project number PN-III-P3.6-H2020-2020-0063.
