摘要

Optimization and reduction of energy consumption and the environmental impact of greenhouse gas emissions are among the most urgent challenges of the twenty-first century. Such challenges call for significant research to be carried out in order to develop new technologies that can enable a transition towards a more energy efficient society, leading to a reduced carbon footprint. Information and communication technologies (ICT) can reduce the environmental impact of human activities by improving energy efficiency in many sectors of the world's economies. However, recent studies indicate that global ICT energy consumption amounts to 7 percent of entire electricity production, which in turn causes about 2 percent of the world's carbon dioxide emissions.
