Energy as one of the factors of production along with labor and capital has an important role in development and social welfare. Due to the pollution of non-renewable resources and its negative impact on welfare, the use of renewable resources can improve social welfare by eliminating pollutants. In this study, the effect of renewable and non-renewable energy consumption on social welfare of de...
Hydrogen production has gained increasing attention as a potential energy carrier, which can utilize many forms of renewable energy, such as biomass, wind and direct solar power. It has increased its significance as fossil fuels are being used up at a high rate and energy security is of greater importance to the United States and many other countries. Furthermore, hydrogen production offers the...
Climate change and the increasing population of countries have made the importance of greenhouses more important for future food security. One of the most important considerations in greenhouse production is the need of energy to create suitable greenhouse conditions. Therefore, in this paper, the problem of greenhouse energy planning with a focus on renewable energies will be investigated. To ...
In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...
By increasing the extraction of natural gas, its role in the restructured power systems is being expanded, due to its lower pollution. Iran has the second largest reserves of natural gas in the world and exports it to different countries. This paper represents long run analysis of natural gas export from Iran to Turkey as a case study, considering direct transfer and exporting via the power mar...
With the increasing population and standard of living, energy demand is increasing. But non-renewable resources are decreasing with for energy. So, we should focus on renewable resources. According to report REN21 in 2019, 73.8%of electricity generated from resources, only 26.2%of where 15.8% Hydropower, 5.5% Wind Power, 2.4% solar PV (Photovoltaics), 2.2% Bio-power 0.4% Geothermal, CSP Ocean p...
Recent estimates and forecasts of the oil, gas, coal resources and their reserve/production ratio, nuclear and renewable energy potential, and energy uses are surveyed. The impact of the rapidly growing economies of the highly populated countries, as well as of the concern about global warming, are presented and assessed. A brief discussion of the status and prospects of fossil, nuclear and ren...
increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
In the present book under review, the reader will have an opportunity to study and understand Australia’s different energy sectors. The reader will update him/herself with the technical, environmental, and economical aspects of energy production. The book’s novelty is in its discussion of the sustainability of different energy sources, ranging from non-renewable to renewable energy sources. The...
