1.Introduction Energy efficiency and environmental performance are mainstream issues for ship operators who are aiming through low carbon shipping and cost reductions. Although reducing fuel consumption seems to have priority, environmental considerations also push the shipping industry to operate in more efficient way. Strict legislations on GHG emissions and increasing fuel prices turn the fo...

Improving end-use energy efficiency—that is, the energy-efficiency of individuals, households, and firms as they consume energy—is often cited as an important element in efforts to reduce greenhousegas (GHG) emissions. Arguments for improving energy efficiency usually rely on the idea that energyefficient technologies will save end users money over time and thereby provide low-cost or no-cost o...

Energy consumption cost and environmental effect are dynamic challenge to cloud computing. Data centers are the backbone of cloud computing. They continue to be challenging problems to energy efficiency. We investigated previous research based on energy efficiency approach and obtained the conditions to facilitate green cloud computing. Reducing energy consumption and emissions of carbon dioxid...

Air pollution is an example of a negative externality; it imposes harmful effects and costs on people other than polluterS. In controlling air pollution, efficiency argument implies that, there is a rolefor the government to play. Studies show that taxation of fuels can be a powerful indirect instrumentfor controlling air polluticn because of the association between fuels use and emissions. In ...

During the past few decades, the encouragement of Iran's economic development programs has brought a series of side effects such as the reduction of resources, the depletion of economic reserves and the subsequent destruction of the environment, In this process, sustainable economic and social development has become a big challenge. Therefore, the aim of the present study is to investigate the ...

The use of agricultural machinery, fuel, fertilizers, and pesticides render agriculture dependent on energy and have negative environmental effects on water, air and land. Therefore, it is necessary to study the process of energy consumption for producting the different products and take the necessary measures to increase the efficiency and decrease the environmental effect of these inputs. In ...

to evaluate antioxidant effects of tomato pomace in broiler diets contained full-fat linseed on the production index, energy and protein efficiency, 396 one-day old ross 308 broilers were randomly allocated to 36 cages for nine dietary treatments with four replicate. this experiment were carried out in a completely randomized design with 3*3 factorial arrangement with three levels of full-fat l...

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...
