Optimal resource consumption and minimization of carbon emission is a great challenge for the Next Generation Internet. Data centres and networking devices consume significant amount of energy. It is imperative to improve energy efficiency, both locally and at Internet level. Currently there is a significant lack of transparency of environmental cost, which should be urgently resolved given the vast scale of resource usage.
There is a need to provide transparency mechanisms on the environmental cost of the Internet. Identification and tagging of most resource consuming elements is also very important and urgent. The research is needed to figure out the alternatives to improving energy efficiency. This will ensure sustainability of the Internet and of the economy relying on it.
