در این تحقیق کارایی مصرف نهایی انرژی در صنایع بزرگ ایران با استفاده از یک تابع تقاضای تعدیل جزیی برآورد و مورد تجزیه و تحلیل قرار می گیرد. ضرایب مدل شامل نرخ تعدیل پویا، کشش های قیمتی مستقیم و غیرمستقیم کشش های درآمدی و ضریب سرمایه بری بوده که به تفکیک حامل های سه گانه انرژی شامل: برق، گاز طبیعی و فرآورده های نفتی با استفاده از آمار ترکیبی دوره (378 1-358 1) برآورد گردیده اند. مدل برای دو گروه ...

Using natural gas is known as a clean energy resource and apart from environmental aspect, it is economically and politically of great importance so that countries having conventional and unconventional gas resources have increased investment in novel tech developments especially in unconventional ones. The aim of this study is to analyze the effect of shale gas production on the gas price in t...

صنایع انرژی‏بر، بخش قابل توجهی از مصرف انرژی بخش صنعت را بخود اختصاص داده‌اند. در سال 90، بیش از 75 درصد از مصرف فرآورده‌های نفتی بخش صنعت، مربوط به صنایع انرژی‏بر بوده است. در این راستا توجه به بهبود کارایی مصرف انرژی در این بخش از اهمیت ویژه‌ای برخوردار می‏باشد. بهبود کارایی در مصرف انرژی پیامدهایی نظیر اثرات بازگشتی و اثرات معکوس خواهد داشت، چرا که کاهش مصرف انرژی متناسب با بهبود کارایی رخ ن...

Despite the presence of 90% of double-fuel taxis (gasoline + CNG) in the urban taxi fleet, fuel consumption choices are more dependent on pricing policies and factors such as gasoline subsidies and quotas, and with the slightest change in fuel rates and quotas, use natural gas fuel. . Impact and challenge fuel management in the public transport fleet. The main purpose of this is to identify way...

In this study, for the first time, we model gasoline consumption behavior in Iran using the long-term memory model of the autoregressive fractionally integrated moving average and non-linear Markov-Switching regime change model. Initially, the long-term memory feature of the ARFIMA model is investigated using the data from 1927 to 2017. The results indicate that the time series studied has a lo...

Electricity plays an important role in the production of various economic sectors.  Power outages can thus impose high costs on these sectors and ultimately on economic growth and development.  The purpose of this study is to estimate the welfare losses resulting from a possible power outage in the productive economic sectors of Iran. This study was conducted in two stages using provincial pane...

Iran is ranked as the ninth largest greenhouse gas producer in the world, with an annual emission of nearly 180 million tons of CO2 by thermal power plants.. The purpose of this research is to simulate and optimize the optimal economic and environmental load dispatch and a portfolio of efficiency improvement strategies on both supply and demand sides in MT1, MT2, and EEP scenarios in using the ...

    Energy is one of the factors used in most economic activities. The economic security of most countries depends on secure access to energy. Therefore, the production and consumption of energy and its optimal use are of particular importance. The purpose of this study is to investigate the relationship between energy consumption and economic growth in the framework of nonlinear self-regressi...
