A part of the Algerian Sahara is a vast region, on which scattered oases where life is possible are grafted, as consequence of water presence. These oases that verge consistency, involve combining homes by their rich architecture, unfortunately at risk of extinction. The protection of this heritage goes exordium by seeking a balance between preserving the historical and cultural identity, and especially the improvement of living conditions of people who inhabit it. Indeed the life standard in these regions is inadequate, hence many villages scattered across the Sahara ksour are dependent on electricity supply in the north. The latter constitutes the major disarray because of the low density, the fundamental mismatch of tissues, and their situations at the expense of depression at the bottom of the slope. Consequently, the electrification of houses and infrastructure is quite difficult and sometimes virtually impossible. It is now appropriate to introduce solar energy that is able to contribute to solving energy problems in many regions of southern Algeria, where all conditions for using solar energy are available. The use of renewable energy in southern Algeria is a strategy for the development of the citizens’ life. This will integrate them into their surrounding contexts in order to stabilize them, namely to safeguard the vernacular heritage in transmitting collective memory.
