Nowadays, environmental pollution is increasing more and more and in the big cities, because of the concentration of the population, is more intense. Air pollution in the big cities has become a serious problem especially in Iran. High fossil fuel consumption of vehicles is a major cause to increase in the amount of air pollution. Using new technology of powertrain, like other developed countri...

Land leveling is one of the most important steps in soil preparation and cultivation. Although land leveling with machines requires considerable amount of energy, it delivers a suitable surface slope with minimal soil deterioration as well as damage to plants and other organisms in the soil. Notwithstanding, in recent years researchers have tried to reduce fossil fuel consumption and its delete...

Abstract: As fuel prices increase and environmental issues become more serious due to the use of fossil fuels, as well as the expiration of fossil fuels, the researchers are looking to find alternative fossil fuels. Using renewable and green energy like solar energy using photovoltaic systems would be a convenient and cost-effective way. It is important to note that the efficiency of these cell...

In recent years, Iran has increased energy prices somewhat, but because of the very low starting point they remain far below opportunity costs. In this paper we examine two broad issues: First, the estimated impact of the energy price (Gasoline and Jet Fuel) rises on producer prices entire the economy and transportation sub-sectors, and the second, the Estimated of gasoline and jet fuel elastic...

The energy crisis during the 1970s sparked the development of renewable energy sources and energy conservation measures. As supply eventually met demand, these programs were scaled back. Ten years later, the hazards of pollution led to work on minimisation and reversal of the environmental impact of fossil fuel extraction, transport and consumption [1]. The United States Department of Energy pr...

Climate change has become a challenge with adverse impacts on the Earth. Reducing the use of fossil fuel is a primary step to solve environmental problems. As the population continues to rise, to meet the growing demand for construction with a large share in energy Consumption, Efforts to make the built environment more energy efficient is crucial. The main objective of this research is to eval...
