Renewable Energy Sources (RES) become important in recent years in research that enlightens the lives of people by meeting their daily electricity demand. This work focuses on shedding light on the utilization of renewable energy sources such as PV in some of the Libyan southern cities (Sebha, Murzuk, Ghat, Ubari, and Wadi Alshatti) to spread peace and avoid internal migrants. Libya with the help of the availability of resources of solar irradiance and wind speed, the load can be met along with reducing the deficit. The obtained green energy from RESs could play a substantial role in meeting Sustainable Development Goal 7 (SDG7) and Climate Action Goal 13 (CAG13) solutions. Hopefully, this study is expected to be a guideline to researchers in the field to assist them in their future studies. In this study, we compared five cities located in southern Libya in terms of global solar radiation, temperatures, and relative humidity, and also compared the productivity of PV modules for a full year by simulating 1 kW of PV modules in each city and the results were good for installing solar panel plants in the aforementioned cities.......................
