Solar energy, wind energy and storage for the electricity grid of today and tomorrow

Photovoltaic (PV) generators and wind turbines (WT) are, nowadays, the most used technologies for power generation. This paper has the primary objective to explain the reasons of this success, in the present and in the future. Secondly, in this paper, an estimation of PV-WT percentage share of the electrical consumption is provided, according to a case study of power generation in southern Italy. The simulation results demonstrate that the PV-WT share can exceed the 40% threshold, considering about 10% of the national consumption located in a region where sun shines and wind blows generously
