The study highlights the importance to develop the national economy through assuring energy security. The study aims to analyze how to develop renewable energy sources, determine the main priorities of Ukraine’s national security policy and discover novel ways of assuring energy security due to developing the industry of renewable energy in the light of environmental safety, energy conservation...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
Energy carriers are addressed today as one of the main pillars of energy generation due to the increased growth of industries in developed and developing countries. According to the global view, increased consumption of energy carriers is causing an increase in the production of greenhouse gases, the global average temperature, and this, in turn, results in the quicker melting of ice in Antarct...
introduction despite the abundant renewable energy sources, the iranian energy sector relies almost entirely on fossil fuel energy resources. power sector is dominant source of co2emissions and responsible for about 35% of total co2 emissions in the country. additionally, long-term electricity demand of iran is expected to grow quickly, which in turn requires extensive investment to meet the gr...
To reduce the GHG emissions of IP over WDM networks, we introduce renewable energy usage at each network node and design the networks considering the state of renewable energy available at each node location. Results indicate that the designed network can save up to 50% or more non-renewable energy consumption in the example scenarios considered here compared with the design method which simply...
Energy consumption is very high in greenhouses mainly due to off-season production. The main source of its energy supply is fossil fuels. Due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. In this research, a solar heating system, equipped with a concentrat...
In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, the application of active solar systems for the dining hall is evaluated. The impact of solar systems and energy management designed for this hall on energy consumption and environment was investigated.This study measures the electricity and thermal energy consumption of the dining hall , p...
This study investigates the relationship between renewable energy consumption, agricultural value added and per capita GDP with CO2 emissions in selected countries of MENA region. The study estimates the values of cointegration amongst the selected varaiables using panel data from selected countries for the period 1990 to 2014. The results indicated a long-run relationship between these variab...
This study investigates the causal relationship between clean and non-clean energy consumption and economic growth in Brazil over the period of 1980–2009. Clean energy consumption at aggregated level of total renewable energy consumption and disaggregated levels of hydroelectric, new renewables, and nuclear energy consumption are tested within a production function framework. A cointegration te...
This paper uses panel cointegration techniques to examine the causal relationship between renewable energy consumption, economic growth and CO2 emissions for a group of 12 MENA countries covering the annual period 1975-2008. The Granger-causality results indicate that there is no causal relationship between these variables in short run except a unidirectional causality running from renewable en...
