Today, policymakers are aware of the substantial advantages of renewable energies. From the point of view of national and regional decision-makers, the first priority of preparing a com-prehensive energy plan and the second priority of determining the share of renewable energy in the total energy production basket of the country is an essential step in the energy policy pro-cess. In choosing from various renewable energy options, environmental dimensions are com-bined with economic, technical, and social criteria, which shows the need to combine these crite-ria, the multi-criteria of the governing decision-making space, and policy-making. Multi-criteria decision-making techniques can play an important role in choosing the best solution and option. The statistical population of this study is eight cities in the case study. The renewable energy sources studied include wind, solar, water, geothermal, and biomass. First, the potential of re-newable energy for the study areas was identified. Then the two main criteria of sustainable de-velopment: economic criteria with 5 sub-criteria and environmental criteria with 3 sub-criteria were analyzed. Finally, using the Economic Analytic Network Process (ANP) sub criterion, the environmental sub-criterion of each of the weighted renewable energies was allocated. One of the essential results of this research is the income of 72868.8 $ from solar power in Ardabil. The cost of energy is $ 2.72 kWh. The lowest cost per unit of energy produced is related to Khalkhal geothermal energy at $ 0.144.

In this research, technical and economic analysis of the use of storage devices in the hybrid system of wind and solar is performed with the aim of providing a maximum electrical load of residential buildings. To this aim, two scenarios of grid-connected and off-grid system have been studied. two parameters of high reliability and cost per production capacity were used. According to these two parameters, due to the low cost of grid energy and the high cost of purchasing the second scenario cell was selected with the grid-connected system approach. Based on this system, the final generation that has a surplus of production sells the energy to the network and uses the network to supply the load when there is a lack of power to supply the load. According to the cases mentioned in the second scenario, more than 50% of the requested load is supplied by the photovoltaic cell, which indicates the high potential of the study area. For the selected system, the return on investment was 7.53 years, considering the cost of energy is 0.13 $/kWh

Due to the needs of modern societies to provide their energy fully or partially from the renewable energy sources and its necessity as a main principle of sustainable development, its necessary to assess and evaluate renewable energy and its integrating for utilizing a part of consumed energy for societies from cheap energy resource and solving the ecological and social problems. Despite of great potentials of Ardabil province in agriculture, water streams, climatic precipitation and climatic conditions, the necessity of appropriate investments in order to better exploitation form these capabilities (renewable energy) increases. The goal of this research is to potentiometry for the exploitation of renewable energies (solar, wind, biomass and bio-energy, water) based on farming, improvement of policy making for developing renewable energies, developing atlas of renewable energies based on farming and improving policy making of developing renewable energies in Ardabil province. According to the results of this study, the most talented town of Ardabil province in terms of renewable energy is Meshgin shahr town. Solar energy 3/449 kW h/m2/y, hydropower 270/34 Gw h/y and geothermal 76/11kw h/y ranked the first among all the cities of Ardabil province. And the lowest was Sarein city.
