Abstract
Electrical energy is a vital sector for humanity, which is why its production is constantly increasing. However, it produces CO2 emissions which are among the factors causing global warming. Aware of this problem and in order to reach the objective of zero greenhouse gas emissions by 2050, multiple countries have decided to switch to renewable energies, in particular, wind energy which is considered the least polluting source of electrical energy. The objective of this paper is to give a quantitative and qualitative study of the development of wind energy in the world, examining its evolution during the last decade, its distribution by regions and leading countries and its share in the global electricity mix while giving an assessment of the most powerful wind farms in the world. The focus is on its impact on electric energy autonomy, job creation and reduction of carbon dioxide emissions, as well as its prospects towards 2050
