Growth and renewable energy in Europe: Benchmarking with data envelopment analysis

This paper conducts data envelopment analysis (DEA) for the purpose of calculating inefficiencies in the European countries' growth using as main inputs the variables typically used in the growth-energy literature nexus such as energy consumption, carbon emissions, employment and capital but also with a particular focus on renewable energy sources (RES) consumption. Since we have a panel data set, we also apply the Malmquist method to calculate total factor productivity and an analysis of peers. Mean overall efficiency has been calculated to be equal to 0.892, while mean pure technical efficiency is 0.569 and scale efficiency 1.798. Countries with remarkable renewable energy performance have medium to low efficiency, while renewable energy laggards are among the most technically efficient countries in Europe. Results from this paper are useful for monitoring and benchmarking purposes with respect to their 2020 renewable energy obligations stemming from 2009/28/ED Directive.
