The aim of this research was to study the energy flow and the modelling of energy use in broiler production in the Guilan Province of Iran. The data were gathered through interview with 25 broiler farm managers out of a total of 146 broiler producers in Rasht, the center of Guilan Province, Iran. The effect of broiler farm size at three levels—small (˂20,000 birds), medium (20,000–30,000 birds)...
Distributed generation (DG) has many uses in commercial and industrial field depends on energy uses such as renewable and non-renewable energy sources. But nowadays it is broadly used with wind and solar power. The main motto behind this is to provide a system which is environmental friendly i. e. greenhouse effect, carbon footprint reduction and limited renewable energy sources which increase ...
Renewable energy types such as solar, wind or geothermal energy have been increasingly considered by different countries over the last few years in order to diversify power sources, reduce dependence on one single of energy, and achieve sustainable energy. On the other hand, rising prices of fossil fuels and the fact that they are finite, environmental pollution and evolution of the related tec...
Energy as a geopolitical factor has gained a special occasion in power games of the world and access to energy resources has become a strategic importance for all levels of hierarchy of global power. Hormozgan province is one of the industrial provinces of Iran and this subject has caused to has been growing energy consumption in the province. Limited fossil energy resources and the problems of...
Current conventional agricultural systems using intensive energy have to be revitalized through new integrated approaches relying on renewable energy resources, which can allow farmers to stop dependence on fossil resources. The aim of this study was determining the amount of input–output energy used in onion (Allium cepa L.) production in Khorasan Razavi province. For this purpose, the data wa...
a r t i c l e i n f o Due to the growing concern about climate change and environmental sustainability, hybrid renewable energy system (HRES), which refers to a system that combines several renewable power sources and a conventional power generator to cover the power shortage when the renewable power is insufficient, has gained more and more popularity over the decades. While the HRES is very a...
The energy demand is sharply increasing due to industrialization, huge population growth, and increased comfort lives etc. This energy demand mostly extracts from the fossil fuels which is non-renewable and the known reservoirs expected to finish in near future. The whole world may face energy crisis soon, altogether the fossil fuel produces greenhouse gasses (GHG) which cause the climate chang...
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...
This paper ascertains which state policies are accelerating deployment of nonhydropower renewable electricity generation capacity into a states electric power industry. A state fixed-effects model is used to simultaneously estimate the effects of multiple state policies in all fifty states. As would be expected, policies that lead to significant increases in actual renewable capacity in that st...
