This paper estimates the efficiency of the power generation sector in the USA by using Window Data Envelopment Analysis (W-DEA). We integrate radial and non-radial efficiency measurements in DEA using the hybrid measure while we extend the proposed model by considering inputs and good and bad outputs as separable and non separable. Then in the second stage analysis we perform various econometric techniques (parametric and non-parametric) in order to model the relationship between the calculated environmental efficiencies and economic growth in attaining sustainability. Our empirical findings indicate an N-shape relationship between environmental efficiency and regional economic growth in the case of global and total pollutants but an inverted N-shape in the case of assessing local pollutants and using the appropriate dynamic specification. This implies that attention is required when considering local and global pollutants and the extracted environmental efficiencies.
