Energy poverty, or the inability of households to afford adequate access to energy services, is an issue that can have a significant effect on the quality of life and even the state of health of individuals and even the overall development of a nation. Since it was first brought into focus more than two decades ago in the UK, this topic has gradually gained the attention of academics and policy makers all across the EU and beyond. The current paper addresses the topic by providing not only a renewed discussion, but also an improved energy poverty indicator (with clear and relevant results at the EU level): the Compound Energy Poverty Indicator (CEPI). Moreover, knowing that the risk of poverty and social exclusion, efficiency of heating systems, total consumption of energy per household and rising energy prices tend to increase the severity of this problem in some countries, CEPI is then included into an econometric model so as to determine some possible factors that tend to put pressure on an already existing issue of energy poverty. The results of this research are expected to be relevant not only for academics (as it offers insights into the structure and severity of this topic within the European Union), but also for national and EU policymakers who are confronted in the field with the problem of sustainable development.

The actual development challenges impose new criteria of national performance evaluation, the concept of wellbeing tending to be measured not just in terms of economic and social dimensions, but also vs. the environment. Accordingly, considering the national environmental performance among the EU countries in 2006–2019 period, we grouped them and concentrated on the clusters registering the highest and lowest levels, analyzing how the components of the human and economic dimensions influence it. Applying panel data models, our main results emphasized that, firstly, for the countries with a better environmental performance, sufficient drinking water, safe sanitation, education, gender equality, and good governance were significant; in the countries with the lowest levels of environmental wellbeing, sufficient food, sufficient to drink, education, and income distribution were insignificant, while the remaining components were relevant. Secondly, in both groups of countries, organic farming and public debt were significant; nevertheless, differences were observed for genuine savings and employment, for which the peculiarities of economic activities seemed to be materialized as different influences upon environmental wellbeing. Our study draws alarm signals regarding the development patterns applied in the EU, seeming to have results that strengthen the sustainable goals, but not sufficient for exceeding the traditional growth-oriented model.

The literature formed around the concept of sustainable development emphasizes that its achievement depends on how its dimensions evolve. Considering that the economic dimension is not an end in itself, but a means for achieving the other two dimensions, we concentrated on the relation between environment and society. Using the framework of Sustainable Society Index, we applied path analysis for identifying the effects of human wellbeing components on environmental wellbeing for 71 countries around the world in 2016. The countries were grouped into two groups—factor-driven and innovation-driven economies—according to Global Competitiveness Report. The main results revealed that once the society develops, the pressure upon the environment tends to move from the necessity of offering the basic human needs to the one regarding superior societal needs. While the least developed nations have to pay attention especially to population growth, safe sanitation and health as primary channels of better protecting the environment, in the case of the most developed countries, the main directions of environmental improvement may be education and good governance. Thus, a high environmental concern has to be cultivated in the development process, whichever its stage, but with distinct directions of action, as shown by this study.
