**Preface to "Modeling Energy– Environment–Economy Interrelations"**

This Special Issue examines the nexus between economic growth, energy consumption, and the environment. Our industrialized world depends on fossil fuels to meet its energy needs, and since fossil fuels are associated with both economic growth and severe environmental degradation, the associations between air pollutants emissions, energy consumption and economic growth must be examined. Additionally, CO<sup>2</sup> emissions are forecasted at the Global Level, and the determinants of renewable energy consumption are discussed, along with an assessment of the economic and environmental impacts of alternative renewable portfolio standards and the possible winners and losers. There is particular emphasis on assessing fossil fuels and renewables' effect on energy poverty conditions in Europe. The findings of this Special Issue will be invaluable to researchers and policy makers.
