Energy is the driving force for the prosperity of western societies. Because of this the energy demand increases steadily plus the consumption of fossil sources of energy. From todays perspective, the European energy system is mainly based on conventional resources. Because of this the energy sector in particular offers high CO2 avoiding potentials. The technologies for the transformation of the energy system are already in place. The diffusion of photovoltaic (PV) technology is on an advanced stage, those of concentrated solar thermal (CSP) technology is on an early market phase. The market for PV is promoted in Germany and other European countries in particular. Due to the political influence, the market is characterized by incentive schemes for the implementation of solar projects. The currently prevailing incentive schemes already provide for the implementation of economically oriented projects. Due to the progressing diffusion, a learning curve effect appears which enables a massive cost reduction with increasing installation capacities of the technology. To realize a supply perspective by renewables for Europe and the MENA region, it is necessary to transform energy in locations where the insolation is higher related to locations in Europe. On the one hand, the MENA region offers very good conditions for large scale expansion of CSP plants, because of its high direct normal insolation. On the other hand, the potential expansion areas are not in rivalry with other ways of utilization. Especially for this region arising perspectives for a long term economic growth and regional stability.
