Bulgaria ranks first in energy poverty in the EU, Ivan Ivanov, Chairman of KEVR, said. About 46% of households in Bulgaria are energy poor. This was revealed by a report on energy efficiency prepared by a consortium headed by INSIGHT_E and funded by the European Commission. The report assesses how number states define the issue of energy poverty and vulnerable consumers, as well as the measures they have taken to cope with the problem. Lithuania and Cyprus rank second. About 30%-35% have problems with heating in winter. They are followed by Portugal, Malta, and Italy (20%-30%). Problems are not related to heating only but to cooling in the summer, too. Bulgaria has the largest share of homes that are not cooled in the summer – 40%-45%.
