**7. Conclusion and future work**

Today, many countries set a policy goal commonly recognized in the long term, energy supply must be laid out more sustainably. The fossil energy source, which is still largely used to satisfy this demand, is the main cause of climate change. Energy demand cannot be satisfied with a sustainable and climate‐friendly way that if energy supply and energy use are reworked in depth. Two lines of action are preferred: first, energy demand should be reduced substantial‐ ly by its more efficient use and voluntary parsimony (sobriety); second, the energy supply in

the future must be based on renewable energy sources. The investments required for this reorganization of the energy system are enormous, and it will change in depth the energy sector and consumption patterns. This requires political framework conditions granted internationally. Compared to this point, we have used in this work evaluating method of cost/ benefit analysis and introduced the economic criteria in uncertain future for the assessment of costs.In the coming decades, nuclear power stations of the majority of countries will reach the end of their life in terms of the installations security. Approximately half of the current electricity supply will no longer be available. Meanwhile, despite the efficiency improve‐ ments, demand continues to increase, with the use of new technologies requiring electricity, population growth, increased consumption possibilities, and substitution of fossil fuels in the areas of heating (heat pump) and mobility (electric vehicles).The accident at the Japanese nuclear plant in Fukushima in March 2011 has raised a new urgency to the question of how the majority of developed countries rely on ensured electricity supply. Nucleartechnology has at least for now lost acceptance; availability to start the "energy revolution" seems to have increased. To meet this energy revolution, we must, however, make decisions under uncer‐ tainty. Always incur certain risks, and it is unclear how to react dynamic system made by humans and their environment. Decisions must be taken, so that the electricity supply remains assured on one hand, and can be adapted to the changed framework conditions on the other.It must also respond to economic issues: how the investments are made in a liberalized electric‐ ity market, in which the generation, transmission, and distribution are separated? How will be the future of the business of electricity supply companies? so they must be compatible with a decentralized production of renewable electricity, more efficient use of electricity by consumers, and maintenance.The supply of future electricity of any country depends largely on technical and economic developments. The preferences of individual electricity consum‐ ers and the behavior of electricity producers and network operators in terms of investments likewise play a central role. Finally, political and legal decisions also influence the future of electricity supply. These decisions concern the efficient use of electricity, renewable electrici‐ ty, the problem of adjustment and storage, network expansion, and liberalization of the electricity market. The decisions of the months and years ahead will influence the supply of electricity for decades. The question therefore arises of the bases on which lay the next milestones. And it is in this context that the AHP‐method‐based consensus was introduced with the details of the opportunities, benefits, costs, and risks of all proposed alternatives. The AHP method combined with BOCR merits becomes popular, looking to its simplicity, flexibility, and intuitive appeal. It was demonstrated that this combination allows the project holder to think objectively and to consider simultaneously profitability, customer satisfac‐ tion, and life quality on one hand and have the certitude that status quo is not sustainable on the other. The future work consists of the issue of combining AHP‐BOCR paradigm with new information and communication technologies to solve the problem of unpaid bills of dimin‐ ished customers by transforming state's aids on energy prepaid cards using the advantages of smart energy counters from one hand and the management of high pick of energy demand by shedding load for customers' owners of emergency resources instead of ordinary customers, using current power lines (CPL) from the other hand.
