The equality implications of tariff design for household gas and electricity, two essential substitutes, present a significant concern for policymakers. In this study, we examine this issue using a sample of household income quartiles across various social groups, exploring the diverse effects of changes in electricity and gas prices. The findings reveal that an increase in gas prices exerts a more pronounced impact on low-income groups compared to an equivalent increase in electricity prices. Our partial analysis indicates that gas exhibits less elasticity, likely attributed to the absence of a suitable substitute in the event of a price increase for this commodity. This observation underscores the lack of energy diversity that is rooted in the critical role of gas appliances in cooking and heating. This phenomenon poses a potential threat to the energy security of Iranian households.

Electricity is one of the essential factors for the economic development in almost all countries. On the other hand, the increasing use of the non-renewable energy, like fossil fuels for electricity generation, would lead to the depletion of the non-renewable reserves. Also, the use of fossil fuels is one of the most important factors contributing to environmental pollution and climate change. Hence, the optimal use of energy in the process of the economic development has always been considered as an important objective for the sustainable development. In this research, a small open economy has been devised by considering a structure for its electric power market based on the Dynamic Stochastic General Equilibrium model, taking into account four main sectors, including households, production, government and the foreign trade sector. Furthermore, the dynamic effects of shocks in the economy on macroeconomic variables have been examined in the study. The simulation and analysis of impulse response functions of the model indicated that the productivity shocks in the electricity industry have significant effects on macroeconomic variables. The adjustment of the effects of shocks takes place in the long run. Moreover, the mechanism of the effect of a consumer’s preferences shock is quite different, and even its adjustment on some macroeconomic variables occurs over a longer period of time compared to the other shocks

Despite self-replenishing nature and lack of negative external effects of new energies, the energies entail higher costs than the conventional energy resources. The governments cannot afford these extra costs, and it needs to take part the public. This study examines extent of public participation in the funding of these costs. The study employed the double-bounded dichotomous choice (DBDC) contingent valuation (CV) method. We release 400 questionnaires under five corresponding prices. Two cost-related questions were asked from each participant (once twice the original price, and once half of that). The interviewees determined the extra cost they would incur, taking into account seven factors, namely: regional economy, demand for electricity, environmental considerations, diplomatic relations, safety, ethics, and the economy. The results suggest a willingness-to-pay of 46360 Rials (≈1.2USD) per month. The findings also indicate that the items including willingness to new energies, importance of environment and influence of the energies have the highest effect on the willingness of payment.

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.
