Google has some ideas on how to lower its electricity bill.
“The ability to seamlessly shift workloads between data centers also creates intriguing long-term energy management possibilities, including a “follow the moon” strategy which takes advantage of lower costs for power and cooling during overnight hours. In this scenario, virtualized workloads are shifted across data centers in different time zones to capture savings from off-peak utility rates.”Well the evidence is in about California. There are some terminally stupid people running that state. Fortunately there are some smart people running Google. As suggested in the article they will probably just bypass California and use Washington State or Oregon State to supply California with bits.
A geographically diverse company like Google could shift its computing loads around to follow low night-time power costs. But it also seems likely that utilities could also bid to fill Google’s computing power needs. States would want to have Google crunch its servers using their utilities power so that they would get the extra utilities tax. And utilities would want to bid to get the extra Google business. (Actually, this probably wouldn’t happen in California, where utilities are incentivized to sell less power, not more.)
