Analyzing Energy Poverty and Its Determinants in Greece: Implications for Policy

Energy and environmental policies in the sector of buildings aim to achieve climate targets while ensuring affordable energy services for households. This study uses the Greek residential sector as a case study and focuses on energy poverty, examining both established and novel energy poverty indicators for its measurement, analyzing the key determinants of energy poverty, and developing statistical models to identify energy-poor households. The same models are also used for assessing the effectiveness of policies and measures implemented or planned to address energy poverty with a view to develop synergies with policies aiming to reduce greenhouse gas emissions. Energy poverty levels in Greece ranged from 8.4% to 19.6% in 2021, depending on the energy poverty measure used. The evaluation of the policies aiming at tackling energy poverty showed that deep energy renovations, combined with space heating system upgrades, can reduce energy poverty by 69–99%. Shallow energy renovations and upgrades of space heating systems, implemented either individually or in combination, are less effective. Finally, while the various subsidy schemes for vulnerable households do not significantly affect energy poverty levels, they play a critical role in alleviating the depth of energy poverty and improving the quality of energy services provided to households.
