Share of renewable energies in Energy Portfolio -How to enhance its share to reach the targets of the resilient economy.

One of the main pillars of the General Policies of Resilient Economy is reducing reliance on oil revenues, so development  and expansion of renewable energies should be taken as the main policies of relevant entities. In the same line, in 2015, implementation of tariff policies, known as Feed in Tariffs (FiT), as a supportive and vastly applied policy across the world, for renewable energy development was launched in Iran. This study makes a comparative analysis of share of renewable energies between Iran and some other countries and proposes, a System Dynamics Model Simulation for the renewable energy development process and also evaluates the strengths and weaknesses of Feed in tariffs policy in Iran . The model considers sociological consequences of financial mechanisms. The results indicate that, the system does  well till 2021, in line with 5GW targets set in the sixth development plan, later on some other mechanisms will prevail, resulting in a financial crisis.  By analyzing the dynamics of the system, three scenarios were examined showing that the optimum policy is to levy annual taxes for development of renewable energies.
