[This is the kind of undertaking that CANARIE is funding under its Green IT
program and hopes to deploy later this year. Cap and trade is going to
dramatically raise the price of energy from coal fired power plants so
schemes like this will be essential for the future Internet. Obviously an
energy aware routing scheme is ideal for networks where all the nodes are
powered by renewable resources. Rather than looking at cost of energy it
would look at the availability of energy. Some excerpts - BSA]

e-Internet-Routing-Scheme
http://www.technologyreview.com/business/23248/
An Internet-routing algorithm that tracks electricity price fluctuations
could save data-hungry companies such as Google, Microsoft, and Amazon
millions of dollars each year in electricity costs. A study from researchers
at MIT, Carnegie Mellon University, and the networking company Akamai
<http://www.akamai.com/> suggests that such Internet businesses could
reduce their energy use by as much as 40 percent by rerouting data to
locations where electricity prices are lowest on a particular day.
Modern datacenters gobble up huge amounts of electricity and usage is
increasing at a rapid pace. Energy consumption has accelerated as
applications move from desktop computers to the Internet and as information
gets transferred from ordinary computers to distributed "cloud" computing
services. For the world's biggest information-technology firms, this means
spending upwards of $30 million on electricity every year, by modest
estimates.
Asfandyar Qureshi <http://web.mit.edu/asfand/www/> , a PhD student at MIT,
first outlined the idea of a smart routing algorithm that would track
electricity prices to reduce costs in a paper presented in October 2008.
This year, Qureshi and colleagues approached researchers at Akamai to obtain
the real-world routing data needed to test the idea. Akamai's distributed
servers cache information on behalf of many large Web sites across the US
and abroad, and process some 275 billion requests per day; while the company
does not require many large datacenters itself, its traffic data provides a
way to model the demand placed on large Internet companies.

The team then devised a routing scheme designed to take advantage of daily
and hourly fluctuations in electricity costs across the country. The
resulting algorithm weighs up the physical distance needed to route
information--because it's more expensive to move data further--against the
likely cost savings from reduced energy use. .The team found that, in the
best scenario--one in which energy use is proportional to computing--a
company could slash its energy consumption by 40 percent. "The results were
pretty surprising," Maggs says.
Spiraling energy consumption has become a major concern for the world's
largest Web companies; a report published by McKinsey
<http://www.mckinsey.com/> & Company and the Uptime Institute
<http://www.uptimeinstitute.org/> in July 2008 estimates that datacenter
energy usage will quadruple during the next decade in the absence of efforts
to improve efficiency.
Koomey suggests that spiraling energy costs could encourage some companies
to consider radical steps such as rerouting data: "Electricity use is a big
enough component of data-center costs that this just might work."
