Energy efficiency has a vital role to mitigate increased power consumption and carbon dioxide emissions. Future wireless communication systems should be designed in such a way that energy efficiency as an important design rule. Heterogeneous Networks (HetNets) have recently being considered as an effective approach to provide better cellular network coverage and capacity. In the proposed system...

The social cost of carbon may be the most important number you’ve never heard of. U.S. climate legislation may or may not make it through Congress this year, but in the meantime, the Environmental Protection Agency is moving ahead, authorized by the Supreme Court to limit greenhouse gas emissions. The Department of Energy is setting energy efficiency standards for residential appliances and com...

Nowdays, energy consumption as a critical issue in distributed computing systems with high performance has become so green computing tries to energy consumption, carbon footprint and CO2 emissions in high performance computing systems (HPCs) such as clusters, Grid and Cloud that a large number of parallel. Reducing energy consumption for high end computing can bring various benefits such as red...

Energy efficiency is likely to influence the characteristics and magnitude of residential energy demand in the future. In particular, improved thermal insulation, patterns of appliance ownership, and turnover of housing stock will change the residential energy landscape. The economics of residential micro combined heat and power (micro-CHP) a technology to provide heat and some electricity to i...

Nowadays, the major challenge of diesel engines development is simultaneous nitrogen oxides and soot emissions reduction without the thermal efficiency drop. Hence, different combustion concepts should be investigated to reach optimum emission and performance conditions in diesel engines without expensive aftertreatment systems. This paper presents the results of a study on a dual fuel (DF) eng...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

Achieving sustainable economic growth is one of the most important goals of countries' economic programs and policies in the current era. Along with economic growth, consumption of energy rises. Since fossil fuels provide a major share of the world's energy, increased fuel consumption is an inevitable feature of economic growth.  Continuation of this trend increases greenhouse gas emmissions, n...
