But a new white paper says that data centers should be the least concerning energy drainer when it comes to the “wireless cloud ecosystem.”
Researchers at The University of Melbourne calculated the energy consumption of the different components that are used to support cloud services accessed through wireless networks. What they found is that energy consumption by the wireless cloud will be massive, and data centers are only a fraction of the problem. Take a look:
