E lectricity has particular importance in the national economy and providing socio-economic welfare. It is considered an essential infrastructure of the countries development. This is why the management of electricity consumption and the formulation of proper policies for it is very important for policy-makers. To do this successfully, it is necessary to identify energy consumption p...

train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. on the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. first, we propose a fuzzy energy ...

drying of agricultural products is a sophisticated process with high energy consumption. energy needed for sustainable development, is one of the biggest challenges facing humanity. the performance of a heat recovery assisted solar dryer was evaluated in this study. drying time, collector efficiency, energy consumption, solar fraction and energy recovery fraction were investigated at different ...

this paper estimates the trend of total energy subsidies from year 2003 (that is 16.68% of gdp) and running a model, predicts that energy subsidies will reach to 20% of gdp by 2019 if subsidies continue. also environmental damage costs of energy consumption have been entered the model (environmental cost-benefit analysis model: ecba model) in addition to the vast amounts of subsidies. so damage...

Energy plays an active role in sustainable development in Iran, both in the sustainable and the development aspects. This study aims to estimate the nexus of economic growth and the renewable energy in Iran during 1981-2012. We employ the Auto-Regressive Distributed Lag (ARDL) model to estimate a log-linear equation. The results suggest that renewable energy consumption is an insignificant driv...

for over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. on the other hand,traditional buildings of iran were designed according to ecological conditions...
