Résumé: The alternative energy is varied according to its source and its alternatives .Energy categories are represented in the non-renewable energy that has an economic efficacy ,however it causes many damage to environment like coal and nuclear power. Another kinds like the continuously renewable energies and the possibility of realizing economic and environmental efficiency unless if ti has been well exploited. In spite of all theses advantages , the progress of of alternative energies suffer several difficulties the most important one is the high financial cost and the specialized manpower. Concerning Algeria the alternative energies is depending on the renewable energy sector instead of the hydrocarbon sector ; since it has the the biggest potential of solar and wind and for this reason Algeria is one of the most countries in the world that has solar energy estimated by 3000 hour in the year , especially in the south . For this reason Algeria has set a strategy to develop the use of renewable energy ; that is depending on the administrative constructions and the charged institution that organizes the use and the exploitation of the renewable energy such as the Governorate Commissioner of developing renewable energies as well as adopting a set of regulations which protect this system. Our study aims to recognize the alternative energy and its types and effects, in addition to that is to know the Algerian capacities in renewable energies . The problematic of our study is about : what is the real position of alternative energies of global energy market ?and where did Algeria arrive in the use of the renewable energies since it si one of the riches countries in this resources , specially the solar energy ?
