“…This trend is in line with the transition from high-emission fossil 241 fuels to clean energy systems to meet the climate targets and the energy independency of 242 national policies. However, energy supply from renewable sources is reported as covering 243 rather a disparate percentage of the annual electricity demand -from 3,76 % (Kalkan et al, 244 2011), between 35 % and 40 % (Eggleston, 2015;Helling, 2018;Radhakrishnan and 245 Viswanathan, 2015) and above 80 % (Kobiski et al, 2015) to almost the overall electricity 246 demand (Walker and Mendler, 2017). Thus, results on its feasibility are not consensual.…”
