At the dawn of the twenty-first century, one of the major problems of humanity is to combine energy and the respect for environment. A problem of sustainable development has been clearly demonstrated in the Earth Summit in RIO (2012). Among the major battles to be fought in this century for the survival of the planet is to include energy efficiency as an international political priority with the reduction of emissions of greenhouse gases. Renewable energy, inexhaustible, clean, are needed in these conditions as a priority.The Algerian energy strategy is decidedly towards sustainable development by integrating the promotion of renewable energy. The legislative and regulatory framework adopted in recent years testifies to this irreversible commitment. A national program for renewable energy and energy efficiency in Algeria allows at the horizon 2030 the production from renewable energies of 40% of the needs of Algeria in electricity. Since twenty years, Tunisia has established the institutional and regulatory framework of energy management in general. A Tunisian Solar Plan (TSP) with 40 projects was launched in December 2009. Its objective is to provide Tunisia a capacity of renewable energy production of about 1000 MW in 2016 and 4700 MW in 2030.
