    The development of smart energy systems is a crucial enabler of the transition towards a decarbonized renewable energy (RE)-based society with universal energy access as it provides flexibility to integrate variable RE sources. This paper analyzes the development of new RE-based smart energy systems while introducing energy technologies and effective methods for energy systems development, recent progress of energy systems by using RE, practical government measures in pioneer countries for energy systems, development with quantitative data for these countries, and PEST (political, economic, socio-cultural and technological) analysis. Our findings show that the development of smart energy systems requires appropriate policies and that thorough collaboration between all national executive agents like national and local governments and citizens in this regard is crucial. Smart energy system development needs to be tailored to local conditions, and due consideration must be given new technologies and methods for development, correct policies, investment, collaboration national/local and their citizens, societal support, and citizens acceptance.

    Abstract Sustainability targets can be achieved by pursuing environmental-friendly and energy-efficient design and construction. Being sub-standard in terms of stability, buildings would pose serious threats to the environment and natural sources. Therefore, having sustainable design and construction is of great importance in building industry. To achieve sustainability targets, recently recycled aggregates attracted special attention. While several studies have been conducted on the thermal and hydrometric characteristics of recycled materials, there are few studies available on the evaluation of the applicability of these materials in buildings. Accordingly, in this study, the performance of four different recycled concrete panels, produced using waste and recycled materials, has been investigated in terms of energy consumption in a residential building using Design-Builder software. Moreover, a model tree algorithm (M5′) has been used to evolve formulas for predicting the total energy consumption in the reference building. To do this, up to 1200 simulations using various recycled materials and glass areas have been carried out in Design-Builder software. The performances of the developed formulas have been evaluated on the basis of statistical measures. The results suggest that M5′ could serve as a valuable tool for the estimation of total energy consumption in residential buildings.

    Abstract Boosting biomethane production makes it possible to offset the required energy in a wastewater treatment plant. In this research, using batch biomethane potential assays, various techniques including pretreatment, co-digestion, and digestion temperature rise were evaluated to increase the methane productivity of municipal sewage sludge (SS). Between thermal and sonication pretreatment methods, thermal pretreatment was shown to be more efficient and there was no need to pretreat SS for more than 0.5 h. Thermophilic digestion of SS led to 160.8% rise in the methane productivity, compared to mesophilic digestion. The most suitable co-substrate for co-digestion with SS was food waste (FW). FW and SS had little negative synergistic effect, however higher FW concentration caused to higher specific methane yield. Thermal pretreatment was not effective on FW. To evaluate the techniques, a combined cooling, heat and power plant was suggested. The energy recovery balance was positive for all the techniques, but co-digestion was not successful to reduce the levelized cost of energy (LCOE). Unlike co-digestion, thermal pretreatment and digestion temperature rise decreased the LCOE. The thermophilic digestion of SS, pretreated at 90 °C for 0.5 h, resulted in the lowest amount of LCOE by 43.70% reduction, compared to the mesophilic single digestion of non-treated SS.

    Abstract Rural electrification challenges in Iran are the most important obstacle to achieve electricity access for the entire population. The current study focuses on finding an optimal renewable energy system to meet the load of a small village by renewable resources. This village faces frequent power outages, common in many far-off villages in Iran. A hybrid photovoltaics/wind turbine/biogas generator/fuel cell renewable energy system is proposed and analyzed for both stand-alone and on-grid application. Fuel cells are used alongside a hydrogen tank, batteries, and a reformer or an electrolyzer, to act as storage devices and backup component. The main goal is to find an optimal configuration that can meet the electricity demand and be satisfactory from both an economic and environmental point of view. The results indicated that using solar, wind and biogas is the most affordable method and that adding fuel cell to this configuration would increase costs by 33–37%, but also improve system flexibility. Using a reformer is more efficient and about 6% less costly, but also creates more pollution. The cost of energy for a stand-alone system with reformer was calculated to be 0.164 to 0.233 $/kWh, while the on-grid system cost of energy was 0.096–0.125 $/kWh.

    Abstract Gasoline is currently the main fuel of choice in many cities worldwide, and hence, the consequent exposure to its emissions, i.e., CO, NOX, unreacted hydrocarbons, particulate matters, lead, sulfur dioxide, and ozone, is inevitable. Among the various solutions put forth to mitigate the toxic gasoline-related air pollution, while improving fuel performance at the same time, is the application of nanoparticles. Considering the above, the present paper aims to review and critically discuss the improvements made in engine performance and exhaust emission parameters by adding nanosized fuel additives in gasoline. Overall, the addition of fuel nanoadditives enhances the thermo-physical properties of the fuel and improves combustion characteristics. Moreover, the inclusion of the fuel nanoadditives generally results in early combustion and shortened ignition delay. In more detail, the optimum quantity of fuel nanoadditives is associated with improvements in ignition characteristics and reductions in exhaust emissions. The present work also scrutinizes the adverse health effects of various gasoline-related emissions. Finally, possible mechanisms underlying the improvements in gasoline properties and its combustion in the presence of nanoadditives are also reviewed and discussed.

    Abstract These days, climate change issues and their impacts on the economy, social and natural system of countries have become the main concern of worldwide, even for those countries that are facing major economic problems. These issues arise from the combustion of fossil fuels. One of the major contributors to global CO2 emission is the transport sector. Therefore, in order to identify the trends and characteristics of transport carbon emissions this study reviews the relevant literature significantly; and decomposes carbon emission in this sector in 7 top transport CO2 emitter countries by applying the logarithmic mean Divisia index (LMDI). The results indicated that, during 2000–15, transport carbon emissions increased in the United States, China, India, Canada, Russia, and Brazil whereas decreased in Japan. Hence, in the majority of these countries, energy conservation strategies were not successfully implemented during the study period. In the majority of countries, the main contributor to CO2 emission reductions was carbon intensity, whereas the main drivers of CO2 emission increases were electricity structure and economic output effects. Reductions in carbon emissions could be achieved by further optimizing energy structures, limiting the private vehicle population. A set of policies and regulations, from demand-side and supply-side, must be implemented to be effective in reducing GHGs emissions.

    This paper presents a multistage stochastic programming model to address sustainable power generation and transmission expansion planning. The model incorporates uncertainties about future electricity demand, fuel prices, greenhouse gas emissions, as well as possible disruptions to which the power system is subject. A number of sustainability regulations and policies are considered to establish a framework for the social responsibility of the power system. The proposed model is applied to a real-world case, and several sensitivity analyses are carried out to provide managerial insights into different aspects of the model. The results emphasize the important role played by sustainability policies on the configuration of the power grid.

    Predominance of fossil-fuel technologies and lack of enough incentives to expand sustainable technologies has intensified energy issues and the global warming problem. Combining mathematical programming and decision-making techniques, this paper proposes a novel comprehensive multistage method to insert sustainability costs in determining the optimum strategy of energy system expansion for an energy-rich developing country. Since the sustainability attributes have the same value respecting all conversion technologies, a nonlinear equal-weight data envelopment analysis is used to evaluate the technologies based on environmental, social and economic sustainability dimensions, the weightings associated with which are calculated. Sustainability costs, including pollutant emission costs, water and land utilization, etc. are then calibrated by the weightings and a mixed integer programming model is used to determine the optimum share of each technology in electricity generation for Iran, during the period of 2013-2040. The results suggest a late shift from fossil-fuel consumption by increasing the share of renewable energies. The model demonstrates that in countries with excessive fossil-fuel resources and high contribution of fossil-fuel technologies, including sustainability costs/benefits cannot lead to commercialization of renewable energy technologies, unless governments design effective incentive/tax policy, or fuel prices ascend again. The recent fuel price drop even deteriorates the situation.

    Abstract In this study the energy and economic flows and greenhouse gas (GHG) emissions of olive oil production in Iran were investigated in terms of a life cycle assessment with considering four main stages of agricultural olive production, olive transportation, olive oil extraction and its oil transportation to the customer centers. Data was collected from 150 olive growers in Guilan province of Iran. Results revealed that the total energy consumption through the olive oil life cycle was 20 344 MJ ha −1 while the mass-based allocation method results indicated that the total energy consumption was 8035 MJ ha −1 . The total energy output was estimated as 23 568 MJ ha −1 . The total GHG emissions was estimated to 1333 kg ha −1 (CO 2 eq) while the mass-based allocation method results indicated that the total GHG emissions was 525 kg ha −1 (CO 2 eq). The agricultural production stage ranked the first in GHG emissions among the four stages with the share of 93.81% of total GHG emissions. Results of econometric model estimation revealed that the impact of human labor, farmyard manure and electricity on olive oil yield and the impact of electricity and chemical fertilizers on GHG emissions were significantly positive.

    Abstract Climate change and global warming have been a focus of attention in several countries in recent years. Greenhouse gas emissions (GHGE) are one of the most significant contributors to an environmental hazard. Electricity generation is frequently associated with adverse environmental consequences resulting from fossil fuel use, with carbon dioxide emissions being the most concerning greenhouse gas issue. Thus, renewable energies (RE) development for electricity generation has been favored in recent decades. The current study's primary objective is to determine the impact of renewable energy development on Iran's carbon dioxide emissions. The study employs a system dynamics approach to examine the effects of renewable energy development in Iran in terms of carbon emissions and examined five distinct scenarios: increasing the feed-in tariff, eliminating fossil fuel power plant subsidies, gradually eliminating fossil fuel power plant subsidies, and two combined scenarios that consider the carbon cost of electricity generation. Based on this model, carbon emissions can be reduced by 7 %–41 % in the 2040 horizon than the Business as Usual (BAU) scenario.
