Cost benefits of energy-aware internet routing

Researchers from Carnegie Mellon, MIT and the networking company Akamai suggests companies that run large data centers can potentially save millions by utilizing an Internet-routing algorithm that moves data where electricity costs are lowest at a particular time. Based on their findings, when considering the cost of rerouting information is compared from possible savings from lower energy costs, experts found that companies can cut 40% of their energy consumption.

There are still concerns in the actual reduced energy consumption and emission that energy-routing systems can bring. According to Jonathan Koomey, a Lawrence Berkeley National Scientist, “”The trick is to be able to control these systems well enough and to create controls that are cheap enough to be able to take advantage of the arbitrage opportunity available from differential electricity prices, without affecting reliability or latency”.
