Due to the lack of fossil fuels and its products quantities, obtaining difficulties, and its global and local high price. It has become necessary to look for other means and methods of providing electrical energy far from fossil resources or support the existing ones. The study is focused on renewable energy sources, especially solar energy (both thermal and photovoltaic), wind energy as well as biomass which are sufficiently available in the Syrian Arab Republic. Utilizing the renewable energy sources is the main focus of this study, in which the investment in the field of photovoltaic energy and economic efficiency will be reviewed and compared to generating electricity using diesel generators.
