The main purpose of this paper is to determine the amount of subsidy required to promote the share of renewable energy in total electricity production. To do so, different scenarios have been studied by a hybrid approach of Computable General Equilibrium model. The results have been created by entering the details of technology-specific information for electricity generation into this model. The result of codification and calibration of the model shows that in the case of applying same subsidy to achieve 10 present shares of renewable energies in total electricity production, there is a need for 851 percent subsidy rate. Although in this case the wind energy is the only activated resource and the solar and biogas sections have not succeeded in achieving any rise in production rate. The other scenario was based on the unequal subsidy, proportional to disadvantage of different renewable energy. The result shows that, to achieve a balance growth of 4 percent energy productions from renewable sources, the rate of subsidy for wind energy should be 887 present. This rate for solar is 1776 present and for biogas is 1585 present. So, in the first scenario, the proper tariff for purchase of electricity from renewable energy is 4100 Rials per kWh. This tariff in the second scenario is 4260, 8520 and 7600 Rials per kWh respectively.

Since the consumption of gasoil and gasoline in the Iranian economy, especially in the transportation sector is high, It is essential to thought serious solutions to improve the efficiency of these two petroleum products in various sectors. Improve the efficiency of gasoline and gasoil coupled with a problem called rebound effect (RE) Where the initial reduction in gasoline and gasoil consumption resulting in improved performance, partially neutralized. It is natural that neglecting the effect of the consumption of gasoline and gasoil would undermine the policy optimization. The purpose of this paper is to measuring the RE and changes in the transport sub-sector activity following a 10-percent improvement in efficiency of gasoline and gasoil. CGE model based on SAM1385 have been used to achieve the purposes of the paper. The results show that following a 10-percent improvement in efficiency of gasoline and gasoil, the maximum amount of RE for gasoline is in road transport sector (27.45 percent) and maximum amount of RE for gasoil is in road transport sector (25.21 percent). The average total RE of gasoline is equal 12.95% and for gasoil is equal 13.79%. It is noteworthy that following a 10-percent improvement in efficiency of gasoline and gasoil, rail transport sector has the greatest increase in activity level (13.4 percent).
