Bapat is also right to point to electricity as a weak link in the system. The centralization of computing can bring dramatic increases in overall energy efficiency, compared to the fragmented, subscale private data centers we have today. The megacenters tend to operate at much higher levels of capacity utilization than the private centers can achieve, and their operators have the skill and wherewithal to install cutting-edge power-management and cooling technologies. At the same time, however, the centralization of computing assets concentrates energy demand, putting new strains on the aging electric grid. Efficiency increases, but vulnerability does, too.

politicians will soon be forced to wake up to the importance of data centers as national assets. maybe data centers can lead the necessary changes to the energy grid?
