The International conference on Green Computing, Communication and Conservation of Energy ICGCE-2013 aims to bring researchers, scientists, engineers and scholar students together to exchange and share their experiences, new ideas, and the research outcome of all possible aspects of Green Computing, Communication and Conservation of Energy ; and to discuss the practical challenges encountered, and the solutions. Green computing or green IT, refers to environmentally sustainable computing or IT. As computing becomes increasingly pervasive, the energy consumption attributable to computing is increasing, despite the clarion call to action to reduce consumption and reverse greenhouse effect The aim green computing is to reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Research continues into key areas such as making the use of computers as energy-efficient as possible, and designing algorithms and systems for efficiency-related computer technologies. The mobile industry is seen as a potential enabler to reduce greenhouse gases. To meet the requirement of low-carbon economy development, it is necessary to reduce the operation expenditure or energy consumption of mobile networks, while maintaining acceptable quality of service. In this regard, the conference aims to establish a forum to bring together research professionals from diverse fields including green mobile networks, system architectures, networking & communication protocols, applications, test-bed and prototype, traffic balance and energy-efficient cooperation transmission, system and application issues. Replacing the classical energy with alternative green energy, such as bio-energy, solar energy and promoting use of clean energy, and that way, polluting emissions to the air will be reduced. Bio-energy is renewable energy derived from biological sources, to be used for heat, electricity, or vehicle fuel. Bio-fuel derived from plant materials is among the most rapidly growing renewable energy technologies. Photovoltaic technology makes use of the energy in the sun, and it has little impact on the environment. Photovoltaics can be used in a wide range of products, from small consumer items to large commercial solar electric systems. This conference brings together the challenging technical aspects for supporting and producing renewable energy with less or no impact on the ecosystems. We solicit both academic, research, and industrial contributions. We welcome technical papers presenting research and practical results, position papers addressing the pros and cons of specific proposals, such as those being discussed in the standard fora or in industry consortia, survey papers addressing the key problems and solutions on any of the above topics short papers on work in progress, and panel proposals. The goal of ICGCE 2013 is to provide a forum for scientists, engineers, and researchers to discuss and exchange their new ideas, novel results, work in progress and experiences on all aspects of green computing and communications, as well as to identify emerging research topics and define the future directions. This conference will be conducted on the following themes: GREEN COMPUTING GREEN COMMUNICATIONS AND NETWORKING GREEN ENERGY GREEN ELECTRONICS AND INSTRUMENTATION GREEN IT SOLUTIONS
