“…In addition to installing a solar tracking controller and a temperature controller for the distillation process, the type of solar receiver used in the new design was changed to a vacuum-tube type to reduce heat loss. The parameters affecting ethanol production include the initial ethanol concentration, the distillation temperature, and the condensation temperature of the ethanol vapor [31].…”

Thailand is an agricultural country with several agro-industrial by-products that can be processed into fuels. Although producing ethanol from agro-industrial by-products is an interesting option, the process of distilling ethanol from fermented agricultural products requires a high temperature to increase the ethanol concentration from 10% to 95%. In this research, solar ethanol distillation equipment incorporating a solar parabolic collector with a vacuum heat absorber tube to increase efficiency by reducing heat loss was designed and developed. An electronic device was used to control the distillation process, maintain the required temperature, and make suitable adjustments to the solar radiation acceptance angles of the parabolic solar collector. Ethanol dilution at concentrations of 10%, 15%, and 20%, and Sato (Thai Rice Wine) were used as the reactant in the distillation process. The result of distilling ethanol distillation with a semi-automatic control using a vacuum-tube parabolic solar collector showed that the thermal efficiency of the receiver was 12.61%, 13.93%, 18.58%, and 17.40%, respectively. The thermal efficiency of the heat exchanger was 11.27%, 10.76%, 13.35%, and 12.35%, respectively. The final concentration of ethanol was 67%, 76%, 82%, and 80%, respectively, and the amount of the distilled ethanol was 330 mL, 352 mL, 398 mL, and 360 mL, respectively.

“…Nevertheless, renewable energies are periodic and uncertain as they mainly depend on resources with stochastic nature. Moreover, system stability and balance between power production and demand are needed to guarantee the security of supply 20,21 . For instance, energy generation in wind turbines and photovoltaic (PV) cells is intermittent depending on environmental factors.…”

Off-grid renewable energy systems are a solution for power generation in areas where access to the grid is not possible or cost-effective; in particular, low population rural areas located far away from grid lines or in rugged terrains. Furthermore, over-reliance on fossil fuels for supplying global energy demand has led to the depletion of nonrenewable resources and environmental issues. This paper presents a feasibility assessment of an off-grid hybrid renewable energy system for a remote rural area in Kohgiluye and Boyer-Ahmad Province in Iran. Regarding the available energy resources in the region, a photovoltaic (PV)-biomass energy system is considered. HOMER Pro software is utilized to find the optimized sizing of the PV-biomass system to fulfill this load demand. The objective function in this optimization is the system's total net present cost. Due to the rapid fluctuation of economic factors in the country, several rates of inflation and discount rate are considered to investigate their influence on the costs of the system. The optimization result for the current inflation rate of 40% and the discount rate of 18% in the country proposes a hybrid energy system consisting of a 3 kW biogas-fueled generator, 4.74 kW PV, 10 kWh battery, and 2.07 kW converter to meet the 2.64 kW peak load and 14.53 kWh/day consumption of the community. The total net present cost and cost of energy are $93,057 and 0.0933 $/kWh, respectively. Finally, the environmental assessment of the proposed hybrid system shows an annual CO 2 emission of 2.95 kg, which means 99.9% CO 2 emissions mitigation compared to a conventional coal-based electrical plant.

“…Therefore, laws and policies must be formulated and implemented in such a way as to minimize side costs while maintaining the dynamism and quality of the environment 5 . Incentive and punitive policies are among economists' proposed policies in this field 6 . It is an incentive policy with subsidies and a punitive policy with energy consumption taxes.…”

Policy‐making in improving the quality of the environment and social welfare and increasing the rate of economic growth to achieve sustainable development has been considered by policymakers in recent years. Punitive policies such as taxes on fossil energy consumption and incentive policies such as subsidies for investment in research and development are among the policies used to achieve sustainable development goals. In this study, using a computable general equilibrium model, two scenarios of subsidy to investment in research and development and subsidy with the taxation of fossil fuels, to double the ratio of investment in research and development GDP have been considered. First, the subsidy rate required to invest in research and development to achieve this goal is determined, and then, the economic, welfare, and environmental effects of the policies implemented are examined. This study shows that in the first scenario, the subsidy rate required to invest in research and development to achieve this goal is 10.74% and in the second scenario is 10.21%. Meanwhile, the required tax rate in the second scenario is estimated at 2.5% of fossil energy consumption. The results show that both the fossil energy tax policy and the research and development subsidy policy are able to reduce energy consumption, air pollution, and social welfare. The reduction in welfare in both scenarios is regardless of the social benefits of reducing greenhouse gas emissions.
