Shortfall of electrical energy in Pakistan is a challenge adversely affecting its industrial output and social growth. As elsewhere, Pakistan derives its electrical energy from a number of conventional sources. The exhaustion of petroleum and conventional resources, the rising costs coupled with extremely adverse climatic effects are taking its toll especially on the under-developed countries l...
The present study mainly aims to determine appropriate strategies for performing relevant educational programs to promote the level of awareness among different people of society to replace non-renewable energy resources with clean and renewable energy resources as well as to prioritize these strategies for use in the educational system of Iran. This study is conducted in two stages. In the fir...
In the past China’s rural areas, home to 70% of its population, suffered energy shortages. China’s indigenous energy resources are limited, with the exception of coal. The widespread use of coal requires large investments in production and transport –making it costly-, and degrades the environment. As a result the Chinese government has implemented an energy policy that aims at the use of renew...
ABSTRACTRenewable Energy Sources (RES) are well – defined as energy sources, that are in abundance within the natural surroundings and are much inexhaustible. In addition, hydroelectricity (HE) is a vital part of world renewable energy supply and hydropower remains a bulk source of electricity generation because of its environmental friendliness in nature. Modeling is the analysis of the ...
Renewable energy systems (RES) have a vital role in a country’s rural and comprehensive development programs. Renewable resources for the generation of electricity (e.g., wind, solar, geothermal, etc.) are typically most abundant and practical resources for development in rural areas. Such green development plans create an opportunity for rural electric utilities that are at a geographical adva...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...
The problem of hydropower plant profit maximization includes simultaneous programming of optimal utilization of water resources and participation in the power market. The present research was performed on a chain of hydropower plants within the Karoon river basin in Khuzestan Province (Iran) (i.e. Karoon 3, Karoon 1, and Masjid Soleyman hydropower plants). In this research nonlinear programmi...
Global development in terms of increased attention to environmental protection and the finite nature of fossil resources have accelerated the use of renewable energies. Renewable energy portfolio standard (RPS), is a government policy to promote the use of renewable energy in the energy consumption basket. The RPS stipulates the minimum amount of renewable energy that each electricity supplier...
The use of air as biomass gasifying agent yields low heating value product gas and is only suitable for heat and power applications. Steam and oxygen gasification on the other hand can increase gas heating value as well as main gas constituents suitable for production of liquid fuels through synthesis processes. Experiments were carried out to investigate the influence of using oxygen enriched-...
