The trend of increasing energy intensity in the country, despite awareness of the officials and managers of the need to take action to improve it, is ongoing. Various studies conducted worldwide to improve the productivity of energy. These studies suggest ways for improving energy intensity; suggestions that will never be implemented, because of lack of utility consideration of actors. In this research, in search for energy intensity reduction barriers in the industrial sector of the country, a game theoretical approach has been applied. In this study’s modeling, energy consuming firms as an actor, compete with each other and the government as an important actor in the implementation or... 

Energy efficiency for Iran, which has large reserves of oil and gas but also has a high energy consumption is important because it ensures the country's energy security and saving each energy unit creates energy exports opportunity. Buildings have high energy saving potential; this sector uses about thirty percent of energy consumption (about half the gas and thirty percent of the annual electricity consumption). Households are not motivated in saving energy because government pays energy subsidy. In this research building energy consumption (in Tehran) modeled by bottom up approach. Then the effect of economic incentive tools such as subsidy, loan and tax on motivation in energy saving...

The purpose of this study is to analyze the economic, welfare, and environmental effects of the policy of reforming energy subsidies in the industrial sector. The policy of reforming energy subsidies has been examined in the form of 6 scenarios based on the elimination of the current system of payment and redistribution of income among households and producers in certain proportions using a computable general equilibrium model. In the static model, economic variables include variables of production, price and net exports at the industry level and GDP variables, consumer price index, household consumption, government spending, investment, total imports and exports, prices and employment of... 

According to increasing energy demand in Iran and the world, the role of natural gas as a relatively clean and cost-effective source has received more attention. Given the high share of the residential sector in the country's natural gas consumption, providing a model for forecasting the demand of this sector is of great importance for policy makers and decision makers in this field. In the present study, we employ three popular methods of machine learning, support vector regression, artificial neural network and decision tree to predict the consumption of natural gas in the residential sector in Tehran according to meteorological parameters (including temperature, precipitation and wind... 

In this study, the ST14 low carbon steel sheet was used as a skin layer in the construction of three-layer laminates. The use of this steel was due to its high mechanical properties and excellent formability. A thermoplastic polyurethane sheet was also used as the core layer. The selection criteria of this polymer were no need for adhesive (for bonding metal to polymer) as well as proper mechanical properties (elongation and strength) and physical (density). The perfect process for manufacturing three-layer laminates is the roll bonding process. To manufacturing a laminate with the desired properties of the designer, the rolling parameters (rolling speed and thickness reduction) must be...

For this reason, governments and various international organizations are looking for a way to change and reform the global energy system. Forecasts indicate a decrease in the share of fossil fuels and an increase in the percentage of renewable energies and hydrogen. Hydrogen has been introduced as the future fuel carrier due to its many advantages such as the... 

The use of natural gas as a thermal fuel is only a part of the various efficiency cases of this precious material. The increasing need for gas to provide energy and fuel, as well as the currency obtained from its sale and export, and the existence of common natural gas resources with neighboring countries, doubles the need to pay attention to this category. The increasing expansion of the quantitative use and diversity of natural gas consumption as an abundant and cheap energy carrier, as well as the imbalance between the supply and demand of natural gas in cold seasons, require planning to create strategic reserves in the country. These reserves play an important strategic role in...

The subsidies targeting law was ratified on October 23, 2009. At mentioned law appointed that the government redistributes up to 50% of earned revenues from price reforming of energy carriers to households by cash and non-cash payments and 30% of earned revenues to the production sector. But reports studies indicate that from 2010 to 2016, the government allocated 93.4% of the revenues to households in cash and non-cash and only 0.7% to the production sector. It can, therefore, be concluded that the subsidies targeting law has not been properly implemented. Indeed, the government has not only failed to fully reform energy carriers prices, but also has increased the households’ share of...
